Imran,
I am not going to use System 3 as the crack filler, totalBoat epoxy is perfectly fine as filler.?

Not an expert on the topic but I did not think west system 3 is designed as a crack filler. I have used it extensively as a general purpose adhesive in lieu of yellow glue like titebond.
I have used MAS penetrating epoxy and boy does it flow. Its best feature is also it¡¯s worse. Sealing the potential escape routes, in some cases, can be challenging. I am sure there are others out there but for filling the narrowest of checks this stuff works.

Lucky,
I used West Systems before, mainly as the crack and hole filler. What I found is West Systems' viscosity is higher, so it tends to leave air bubbles when filling the deep crack and hole. That is why I bought the TotalBoat epoxy with low viscosity. I will probably try System Three G-2 epoxy in my next rocking chair build.
Polyurethan glue should be fine as the wood glue. The UK woodworker from Bradshaw Joinery uses Polyurethane exclusively.?

I would not use epoxy for edge banding.
I used TotalBoat clear high performance epoxy?to glue the arm to the rear leg for the rocking chair. I thought the epoxy?bond was stronger than Titebond III. This is the first time I used epoxy in the chair

But the result is not what I expected. The glue line of the front leg to seat using Titebond III is so much better (perfect) than the arm to rear leg joint using epoxy. It seems like epoxy had the chemical reaction with the walnut, no matter how much sanding
I did, I cannot get rid of the dark color on the glue line.
From now on, I will only use Titebond III.

I missed that the uprights were veneered, I thought they were solid. If you use a pattern to cut the odd shape, could
you not use that same pattern to create a support that would hold the uprights in the same orientation that you did the half lap/dado's? Essentially a jack that would hold the piece so that the top was parallel to the table surface. Then you could just use
the same program style with two cuts per opening to trim the edge banding flush with the existing slots.

Re: Cantilevered Lumber Storage Ideas
Gents,
?
All of you have had great ideas.? I really appreciate you leaning in.? ?I made some deals with my wife to get the new shop.
?
- The garage needed to go back to being JUST a garage.? No tools, no wood, no storage creep.? After having the vehicles back in the Garage for a few months, I agree.
- I just built my 990 sqft shop and part of the plan was that I already had a separate shed for the wood/sheet goods.? I do not have space in the new shop for storage.
- The shed is 50 yards from the shop across a concrete patio and pathway.
- The shed's door is 43" wide and 76" tall (I know, I did not build it) and is centered on a wall.? No stackers or forklifts for me, for now.? They would not fit down the path or in the shed. Someday I would love to add and reconfigure to allow for that.
- If need be, I can back up my truck right to the shop entrance and deliver lumber to the shop.
?
So, looks like I need to buy some racking...

Re: Sliding Table ¡°90 Degree Jig¡±
#sawsetup
Lucky -?
Trial and error the arcs vs. thickness, but I'd say at 3mm thick most edge band will pull in nicely on gentle radii given good end-point clamping,?1.5mm might start feeling flimsy. Keep shelf?vertical, banding laying?across top, clamp one end secure and pull it down by hand to the other end then clamp final?end. If you have a frame press or assembly table with stop?dogs and?extending clamps, it's super easy and hands free.? If you take Mike's band clamp concept one step further, you could band clamp the arc across a bench top with the straps fastened at the ends of the bench and the board assembly secured vertically in the middle and get both hoop tension and downward compression spread across the entire surface simultaneously in one action as well.
Lipping the edgebanding on the widebelt sounds smart and easiest when you have one available. By scoring, I was referring to the excess length ends of the edgebanding. On softer woods I often just slide a razor edge to sever enough fibers to allow a snap-break. On harder woods, chisel/mallet until similar can be achieved, sometimes angling the?blade for a guillotine effect.? It's quick and true when I know I'm following up with sanding/finishing. If your bands are 3mm or less, probably 2-3 good blows with a chisel already wide enough for the board thickness, then snap, you're on to sanding and no tearback.
Kumiko? Oh yeah!

Hi Brett:

Thanks so much for the encouragement. I appreciate your thoughts ¨C and I don¡¯t think you¡¯ve missed anything. The power of brainstorming is such that even if multiple ideas end up getting dismissed, there is
no telling what new ideas or solutions arise from those initial ones.
?
For example, I had never thought about the success of edge banding by fastening just the ends. I can picture how that would work but I¡¯d be so fearful that the glue line might not be ¡°perfect¡± along the arc.
But this raises another question: what thickness of edge lamination would you use? The face laminations are 3mm, but I find this a bit too stiff for the curve, although it is quite a gentle curve. I have prepared 31mm x 2mm thick strips for the lamination
project. But I can thin these down further in my wide belt sander, to 1.6mm which is the thinnest it will do without a carrier, although I¡¯m sure I could play with the manual ¡°cam-action¡± controls and trick the machine in going thinner. As a solid wood guy,
I don¡¯t have a lot of experience with edge laminations, and I¡¯m (irrationally) fearful of going ¡°too thin¡± ¡

I totally understand your nailing comment. I¡¯ve become very respectful of the use of nails, especially the plastic nails shot by Omer guns. I do have a 23g pinner and it is indeed nearly invisible. But I just
can¡¯t bring myself to use nails on this build!
?
I¡¯m not sure what you mean by the scoring comment? I¡¯m going to send the uprights through my widebelt sander one more time each side to clean up the width of the lamination and bring it flush to the Zebrano
faces. Is that what you mean? As for the lengths, Zebrano at 2mm is too thick/hard to score easily, hence the thought of using a hand saw, or going the router with backer method suggested by Imran and James. I may have missed your point entirely.
?
I¡¯m excited by this build. Wait until you see what I have planned in terms of ¡°kumiko windows¡± in the uprights, featuring solid copper strip (30mm x 3mm) for the kumiko details. I really need a shaper origin

Forgive if my thoughts are misguided, I might have missed some details of context:
1. If you are cutting the curve in the boards, assuming concave, save the outside waste cut to make a clamping caul for the edgeband to sandwich until glue is set.
2. I have successfully?glued bows in solid edgebanding?by simply flexing across the arc and fastening the ends only.
3. If you can bury a nail or staple without destroying the sancitity?of the build...I feel you squinting at this remark ...? esp if a 23ga pin nailer shooting double toenails will hold, they are practically
invisible.
4. Solid edgeband end trimming success is so species dependent, but I generally prefer scoring outside edge in until bend/break and leaving proud enough to power sand or block sand to contour.
5. This set is going to be awesome finished, already loving the proportions and joints now - great work Lucky.
?
I would make the caul (one side matching the shelf curve and flat on the other side), use the regular clamps. You can make the caul the same length as the shelf's, so you can use the router to trim the lamination.
Power tools with the proper jigs are always my?preference.

Hi Brian:

Apologies, I should have provided more detailed photos.

The bookcase uprights in Zebrano are composed of a solid wood core lamination with 3mm thick shop sawn Zebrano veneers on both faces. This is the
material I¡¯ve been machining for the half laps.
?
?
?
If you look closely at the photo below, you can see that I have edge laminated the back side of the uprights with Zebrano veneers, prior to the half
lap machining process. This worked well.
?
?
The problem with the front edge is that it will be curved. I could not machine the curve until the half lap joints were done. This means that the
front edge laminations have to be applied after the machining is done.

The horizontal shelves sit out from the uprights by 20mm. In the photo below you can see how the shelves are proud, and you can see the laminated
nature of the uprights.
?
?
My dilemma is how best to apply/trim laminations to the front edge,
between each shelf, on the soon-to-be-curved front edges of the uprights. Gluing will be tedious. I¡¯m thinking of using dozens of clamps like this:
?
?
But how to trim the laminations to length after the glue dries? I guess the flush cut hand saw method is the best one I can think of.
?
Lucky

I'm not following the need to laminate the front edges of the uprights? The sides are solid wood, correct? Are you doing
it to cover the slots and make the front surface proud of the shelves by 2mm? Color me confused...

Hi FOG:

By way of update, the aforementioned Leitz blade is phenomenal. It cuts as smoothly as any blade I¡¯ve owned which is saying something for such a large blade with relatively narrow
kerf width of 3.5mm. The details appear again here, just in case anyone else wants to consider it as a 400mm blade option: item number 133130, 400mm diameter, 3.5mm kerf. 2.5mm body, 30mm bore, 96 teeth, 10 degree irregular pitch, ATB.
?
This is the first time I¡¯ve used a blade of this size. The dust it throws off is horrendous; I assume it has something to do with making 125mm and 135mm deep cuts. My 3M Dustmaster
is in continuous use.
?
?
This is very fine dust from a couple of hours work at the saw:
?
In the end, the powered rip fence and associated programming has been gold. I¡¯ve used the special programs on the overhead display a lot, including rebating, trenching, etc., but I
must say that I have not really used the specific programming mode for the Kappa 400. It is wonderful.
?
There are 10 program positions, and each of those 10 has 100 spaces to enter specific parameters that can be called up at the press of an arrow key and the start button on the overhead
display. You can imagine its use as follows. For the first half lap joint, I needed a cut at 125mm deep, at 120mm from the end of the Zebrano board. So for P1 (where ¡°P¡± stands for ¡°Program¡±), number 1, I¡¯ve entered 125mm blade height, 0 degrees blade tilt,
and 120mm rip fence position. It works out that I need the fence (which is acting as a bump stop) to move over 16.1mm to give the half lap width I need, so I¡¯ve programmed the number 2 position with 125mm blade height, 0 degrees blade tilt, and 136.1mm rip
fence position for the second cut (i.e. both shoulders of the lap joint). And so forth and so on for all 7 half lap joint positions along the bookcase upright. After 4 cuts, my rip fence is out at about 1150mm. So at this point I have to flip the upright end
for end and start again on the final 3 shelf positions (working from the top of the uprights). This is made easy using the programming on the Kappa 400. Obviously my uprights all need to be dimensioned accurately which I have done.
?
I forgot to say that I could not use special programming function which the Kappa 400 offers, where the rip fence can be programmed for a number of grooves or trenches of a specific
width and depth, at fixed intervals. The reason? Because my shelves are deeper at the bottom and much shallower at the top, so the position of each half lap joint on the uprights is of decreasing distance (from the bottom up) and increasing distance (from
the top down). Programming mode made this process easy. Seems like cheating. Comparing uprights at random, and I¡¯d say the 0.1mm claimed tolerance is verified. I¡¯ve used lots of compressed air between cuts to make sure registrations are accurate, and I¡¯d say
the Kappa 400 has worked as advertised. I strongly recommend a Felder powered rip fence as a wonderful option.
?
Anyway, the 3.5mm blade width allowed for 6 passes to remove the waste for each half-lap joint. No drilling, no knocking out timber, no marking lines, and definitely no chiselling.
I¡¯ve decided I can live with the bumpy but regularly reliable surface in the middle of each half lap joint.
?
?
Last night I assembled the first and smallest of the bookcases. It went together very nicely but I think I¡¯m going to tweak the Walnut shelves (through the wide belt sander) so the
fit is less tight. In the picture below, you¡¯ll see the upper shelves don¡¯t seem the correct width. That¡¯s because the uprights have not been curved yet, to reflect the design where shelves at the bottom are full depth (260mm) while the shelves become less
deep by the top (210mm).
?
l¡¯ll use a template to pattern route the curve after I¡¯m completely satisfied with the joinery. And then another tricky part is headed my way: I have to edge laminate 2mm solid Zebrano
onto the front edges of all the curved uprights. I¡¯ve agonised over this because I could not cut the curves and laminate before machining the joints because I needed parallel edges. Adding the solid wood lamination to the edge after the machining is going
to be time consuming and I¡¯m not sure how best to do it. I could apply over long sections to each curved edge (between shelves) and then flush them, but how?
?
-
Router (risk of splinters)
-
Chisel (not looking forward to that)
-
Flush cut hand saw (might be the best option)
-
Cut the lamination exactly to length and glue it exactly in position¡
?
If I used the flush cut handsaw, I could use overlength Zebrano pieces (but maintaining continuous grain) and then not stress the clamping process. I guess after that many cuts (224
to be precise) I¡¯ll be pretty good with the flush cut saw? Thanks for your brainstorming thoughts!

Hi David B and Michael:

Funny you should mention the flatbed CNC. Although not the same, I have been pondering how much use I¡¯d get out of a Shaper Origin. That tool would fit nicely somewhere in my shop!
?
Thanks David for your vote on the vertical method. I think the clean corners are swaying me strongly for that option. I¡¯ve wondered if I make a very accurate registration jig and use
a small pattern bit (I can get an 8mm dia. bit from across town) to establish the majority of the 20mm flat across the joint, then there would be very little chisel work at all:
?
¡¤????????
corners squared by the saw blade
¡¤????????
majority of waste drilled out
¡¤????????
shoulder established by the pattern bit
¡¤????????
minor chisel work to finish.
?
Your jig making has always been a source of inspiration for me. Your lock mitre jig is especially egregious! I absolutely love it. Of course, now I know I should have made a much larger
vertical jig that does not depend on the crosscut fence for registration. Something like what you¡¯ve done would have been much better. Cheers.

I actually like your original concept of using the rip as a bump-stop, a 400mm blade cutting both edges, and a jig on the crosscut fence to hold the material vertically.? Here¡¯s a couple more jig I¡¯ve

Thanks for your ideas. You¡¯re correct about the slotting blade. If I go the vertical machining route I¡¯ll need nearly every bit of the 400mm blade¡¯s depth of cut. If I were to go back

You have rightly identified the time-wasting point of needing to take two passes (minimum) and then deal with the waste by drilling a hole with a forstner bit to get rid of the septum.
I would then have to mark and chisel the waste which is fine for 1-10 joints, but not 280 trenches¡

Methodology Quiz
How would you make 280 non-through cuts that have to be precisely machined at 125mm deep and 20mm wide?
?
-
Vertical method as discussed to date using the 400mm sawblade, to make two cuts to establish each shoulder, drilling out the waste, and then A) mark a line and use a chisel to square up the joint,
or B) use a router and small pattern bit to establish the shoulder and then chisel out the corners.
?
-
Horizontal method using the same dado stack that machined the shallow trenches, dado raised all the way up for the stopped cut, and then employ either option A or B above to clean up the joint.
?
-
Rely on the existing shoulders of the trenches (5mm deep on both sides), and use a router and pattern bit to obtain the 125mm ¡°half lap¡± joint, and then square up the joint using option A or B above.
?
-
Something else?
?
I personally can¡¯t see a way to avoid handwork of some kind. The reason why I favour the vertical method (as I¡¯m calling it) is because I can get precise and square internal corners
for the stopped cuts. I find it much easier to clean out the waste if the corners are already established. I have never liked chiselling corners square, even with a square chisel (e.g. Veritas). And I would
hate chiselling 560 corners!
?
Thanks in advance for your input,
Lucky
?
I have another more stable jig for demonstrating tenoning on the slider that could be adapted for this also.

Hi Brett:

I don¡¯t have a lot of experience with edge laminations, and I¡¯m (irrationally) fearful of going ¡°too thin¡± ¡

I totally understand your nailing comment. I¡¯ve become very respectful of the use of nails, especially the plastic nails shot by Omer guns. I do have a 23g pinner and it is indeed nearly invisible. But I just

How would you make 280 non-through cuts that have to be precisely machined at 125mm deep and 20mm wide?
?
-
Vertical method as discussed to date using the 400mm sawblade, to make two cuts to establish each shoulder, drilling out the waste, and then A) mark a line and use a chisel to square up the joint,
or B) use a router and small pattern bit to establish the shoulder and then chisel out the corners.
?
-
Horizontal method using the same dado stack that machined the shallow trenches, dado raised all the way up for the stopped cut, and then employ either option A or B above to clean up the joint.
?
-
Rely on the existing shoulders of the trenches (5mm deep on both sides), and use a router and pattern bit to obtain the 125mm ¡°half lap¡± joint, and then square up the joint using option A or B above.
?
-
Something else?
?
I personally can¡¯t see a way to avoid handwork of some kind. The reason why I favour the vertical method (as I¡¯m calling it) is because I can get precise and square internal corners
for the stopped cuts. I find it much easier to clean out the waste if the corners are already established. I have never liked chiselling corners square, even with a square chisel (e.g. Veritas). And I would
hate chiselling 560 corners!

Thanks in advance for your input,

I have another more stable jig for demonstrating tenoning on the slider that could be adapted for this also.

Re: Sliding Table ¡°90 Degree Jig¡±
#sawsetup
Lucky -?
Forgive if my thoughts are misguided, I might have missed some details of context:
1. If you are cutting the curve in the boards, assuming concave, save the outside waste cut to make a clamping caul for the edgeband to sandwich until glue is set.
2. I have successfully?glued bows in solid edgebanding?by simply flexing across the arc and fastening the ends only.
3. If you can bury a nail or staple without destroying the sancitity?of the build...I feel you squinting at this remark ...? esp if a 23ga pin nailer shooting double toenails will hold, they are practically invisible.
4. Solid edgeband end trimming success is so species dependent, but I generally prefer scoring outside edge in until bend/break and leaving proud enough to power sand or block sand to contour.
5. This set is going to be awesome finished, already loving the proportions and joints now - great work Lucky.
I would make the caul (one side matching the shelf curve and flat on the other side), use the regular clamps. You can make the caul the same length as the shelf's, so you can use the router to trim the lamination. Power tools with the proper jigs are always my?preference.

Hi Brian:

Apologies, I should have provided more detailed photos.

The bookcase uprights in Zebrano are composed of a solid wood core lamination with 3mm thick shop sawn Zebrano veneers on both faces. This is the material I¡¯ve been machining for the half laps.
?
?
?
If you look closely at the photo below, you can see that I have edge laminated the back side of the uprights with Zebrano veneers, prior to the half lap machining process. This worked well.
?
?
The problem with the front edge is that it will be curved. I could not machine the curve until the half lap joints were done. This means that the front edge laminations have to be applied
after the machining is done.
?
The horizontal shelves sit out from the uprights by 20mm. In the photo below you can see how the shelves are proud, and you can see the laminated nature of the uprights.
?
?
My dilemma is how best to apply/trim laminations to the front edge,
between each shelf, on the soon-to-be-curved front edges of the uprights. Gluing will be tedious. I¡¯m thinking of using dozens of clamps like this:
?
?
But how to trim the laminations to length after the glue dries? I guess the flush cut hand saw method is the best one I can think of.
?
Lucky
?
I'm not following the need to laminate the front edges of the uprights? The sides are solid wood, correct? Are you doing it to cover the slots and make the front surface proud of the shelves by
2mm? Color me confused...

Hi FOG:

By way of update, the aforementioned Leitz blade is phenomenal. It cuts as smoothly as any blade I¡¯ve owned which is saying something for such a large
blade with relatively narrow kerf width of 3.5mm. The details appear again here, just in case anyone else wants to consider it as a 400mm blade option: item number 133130, 400mm diameter, 3.5mm kerf. 2.5mm body, 30mm bore, 96 teeth, 10 degree irregular pitch,
ATB.
?
This is the first time I¡¯ve used a blade of this size. The dust it throws off is horrendous; I assume it has something to do with making 125mm and 135mm
deep cuts. My 3M Dustmaster is in continuous use.
?
?
This is very fine dust from a couple of hours work at the saw:
?
In the end, the powered rip fence and associated programming has been gold. I¡¯ve used the special programs on the overhead display a lot, including rebating,
trenching, etc., but I must say that I have not really used the specific programming mode for the Kappa 400. It is wonderful.
?
There are 10 program positions, and each of those 10 has 100 spaces to enter specific parameters that can be called up at the press of an arrow key and
the start button on the overhead display. You can imagine its use as follows. For the first half lap joint, I needed a cut at 125mm deep, at 120mm from the end of the Zebrano board. So for P1 (where ¡°P¡± stands for ¡°Program¡±), number 1, I¡¯ve entered 125mm blade
height, 0 degrees blade tilt, and 120mm rip fence position. It works out that I need the fence (which is acting as a bump stop) to move over 16.1mm to give the half lap width I need, so I¡¯ve programmed the number 2 position with 125mm blade height, 0 degrees
blade tilt, and 136.1mm rip fence position for the second cut (i.e. both shoulders of the lap joint). And so forth and so on for all 7 half lap joint positions along the bookcase upright. After 4 cuts, my rip fence is out at about 1150mm. So at this point
I have to flip the upright end for end and start again on the final 3 shelf positions (working from the top of the uprights). This is made easy using the programming on the Kappa 400. Obviously my uprights all need to be dimensioned accurately which I have
done.
?
I forgot to say that I could not use special programming function which the Kappa 400 offers, where the rip fence can be programmed for a number of grooves
or trenches of a specific width and depth, at fixed intervals. The reason? Because my shelves are deeper at the bottom and much shallower at the top, so the position of each half lap joint on the uprights is of decreasing distance (from the bottom up) and
increasing distance (from the top down). Programming mode made this process easy. Seems like cheating. Comparing uprights at random, and I¡¯d say the 0.1mm claimed tolerance is verified. I¡¯ve used lots of compressed air between cuts to make sure registrations
are accurate, and I¡¯d say the Kappa 400 has worked as advertised. I strongly recommend a Felder powered rip fence as a wonderful option.
?
Anyway, the 3.5mm blade width allowed for 6 passes to remove the waste for each half-lap joint. No drilling, no knocking out timber, no marking lines,
and definitely no chiselling. I¡¯ve decided I can live with the bumpy but regularly reliable surface in the middle of each half lap joint.
?
?
Last night I assembled the first and smallest of the bookcases. It went together very nicely but I think I¡¯m going to tweak the Walnut shelves (through
the wide belt sander) so the fit is less tight. In the picture below, you¡¯ll see the upper shelves don¡¯t seem the correct width. That¡¯s because the uprights have not been curved yet, to reflect the design where shelves at the bottom are full depth (260mm)
while the shelves become less deep by the top (210mm).
?
l¡¯ll use a template to pattern route the curve after I¡¯m completely satisfied with the joinery. And then another tricky part is headed my way: I have
to edge laminate 2mm solid Zebrano onto the front edges of all the curved uprights. I¡¯ve agonised over this because I could not cut the curves and laminate before machining the joints because I needed parallel edges. Adding the solid wood lamination to the
edge after the machining is going to be time consuming and I¡¯m not sure how best to do it. I could apply over long sections to each curved edge (between shelves) and then flush them, but how?
?
-
Router (risk of splinters)
-
Chisel (not looking forward to that)
-
Flush cut hand saw (might be the best option)
-
Cut the lamination exactly to length and glue it exactly in position¡
?
If I used the flush cut handsaw, I could use overlength Zebrano pieces (but maintaining continuous grain) and then not stress the clamping process. I
guess after that many cuts (224 to be precise) I¡¯ll be pretty good with the flush cut saw? Thanks for your brainstorming thoughts!

Hi David B and Michael:
?
Funny you should mention the flatbed CNC. Although not the same, I have been pondering how much use I¡¯d get out of a Shaper Origin. That tool would fit
nicely somewhere in my shop!
?
Thanks David for your vote on the vertical method. I think the clean corners are swaying me strongly for that option. I¡¯ve wondered if I make a very
accurate registration jig and use a small pattern bit (I can get an 8mm dia. bit from across town) to establish the majority of the 20mm flat across the joint, then there would be very little chisel work at all:
?
¡¤????????
corners squared by the saw blade
¡¤????????
majority of waste drilled out
¡¤????????
shoulder established by the pattern bit
¡¤????????
minor chisel work to finish.
?
Your jig making has always been a source of inspiration for me. Your lock mitre jig is especially egregious! I absolutely love it. Of course, now I know
I should have made a much larger vertical jig that does not depend on the crosscut fence for registration. Something like what you¡¯ve done would have been much better. Cheers.

Lucky

I actually like your original concept of using the rip as a bump-stop, a 400mm blade cutting both edges, and a jig on the crosscut fence to hold the material vertically.
?Here¡¯s a couple more jig I¡¯ve made to stimulate your thinking.? I could quibble over the actual jig configuration (hence these photos of jigs I¡¯ve made to hold vertical materials on the slider as food for thought).

Thanks for your ideas. You¡¯re correct about the slotting blade. If I go the vertical machining route I¡¯ll need nearly every bit of the 400mm blade¡¯s
depth of cut. If I were to go back to the horizontal setup, I could remount the dado blade, set it to maximum height, and make a partial cut. This may well be a better solution because it gives me the exact width (to match the existing shallower trenches).

You have rightly identified the time-wasting point of needing to take two passes (minimum) and then deal with the waste by drilling a hole with a forstner

Re: Sliding Table ¡°90 Degree Jig¡±
#sawsetup
Michael:
Thanks for your clamp alternatives. I had not thought of the band clamps. I have heaps of those. Cheers.
?
Imran:
A backing piece is a good idea. Zebrano splinters quite nicely (unfortunately), maybe like white oak, but not as bad as Wenge. So care is definitely needed. Thanks for your ideas.
?
James:
The caul idea is one I had considered only briefly as I was hoping to avoid the effort of making one or more. That said, it would allow me to position all 8 pieces of lamination at the one time and then use
a reasonable number of clamps (band, bar, f-style, whatever), as the caul could be full length (just under 2200mm long).
?
Your idea of making multiple cauls to match the curve of each section and then use the caul as the backing board for routing to length ¡ that combines the clamping and trimming ideas. I would need to make
a bunch of separate cauls because the curve is irregular (progressive) and the intervals between each shelf is different. But it may be worth the effort because there are 16 uprights and 128 pieces of veneer to glue and trim (either end).
?
Thanks a lot for your input.

Re: Cantilevered Lumber Storage Ideas
Just use some sticker boards and stack on the ground, separating layers by chosen?criteria, gives you room to insert a stacker with forks to lift/separate. protects lumber, safe and cheap.
Cheap 1000# rated stackers are easily available new and used and will allow access to parts under the pile.
Otherwise make/buy a custom pallet size to keep wood off direct ground contact and/or water soaking hazards and stack even though you will cry when it comes times to pick and sort out for projects.
If you have to cut lumber to length?to fit horizontally, consider for the benefits of vertical storage instead, resulting in fewer shorts that are too short to be useful. You could bundle them together with cam straps into shocks (like old style crop shocking) that would?allow them to freestand instead of putting excessive leaning stress on a substandard structure.
I had a nice cantilever rack from McMaster-Carr. ?

The parts were light enough to move by hand and it held plenty of lumber and plywood I even used one set of arms for the infeed to my cutoff saw.? Access for the stacker to load and unload material from the rack was also good. ?

Two 8' long pallet racks along each side and just span across them. You could put in as many cross members as levels you desire. That or Metro style racking and again, span between two units to create levels of storage.

On Saturday I was lucky enough to find a shop selling a stack of Walnut, Mahogany and White oak for an amazing price. I jumped at it and rented a 6x12 uhaul trailer. Upon arrival at the shop it was obvious that they had come into the wood for free and really had no way of using it in the cabinet business they had. They were making builder paint grade stuff.
It totally filled the 6x12 trailer. It is about 4000 pounds of lumber. When I got home I sorted it. These numbers are conservative:
- About 200 bdft of walnut - off cuts mostly and not very valuable IMHO - cutting board stuff
- About 600 bdft of 4/4 mahogany - nice, wide and clear some 16" widths
- About 100 bdft of 5/4 mahogany - nice, wide and clear
- About 350 bdft of 5/4 rift sawn white oak - really good stuff - a few 13" widths
- About 140 bdft of 4/4 rift sawn white oak - some skip planed
- About 25 bdft of 6/4 rift sawn white oak
I paid less than 10% of what it is worth in So Cal.
Now that the gloating is done, I need a way to store this.
I have a 10'x10' shed on a concrete pad that is 8' tall that is my wood storage. The traditional wall mounted racking will result in this sheds demise as it is not built to handle those loads. I have looked into the traditional 8' tall steel cantilevered rack. I can get it for about $1k locally with 4 adjustable shelves, and that may be a great investment. The drawback is that it is way over engineered for my use. the uprights are 10" deep and the bases are the same 10" tall. The shelves are only 4" thick.
Anyone have a better idea? I do not have a welder...

I would make the caul (one side matching the shelf curve and flat on the other side), use the regular clamps. You can make the caul the same length as the shelf's, so you can use the router to trim the lamination. Power tools with the proper jigs are always my?preference.

Hi Brian:

Apologies, I should have provided more detailed photos.

The bookcase uprights in Zebrano are composed of a solid wood core lamination with 3mm thick shop sawn Zebrano veneers on both faces. This is the material I¡¯ve been machining for the half laps.

If you look closely at the photo below, you can see that I have edge laminated the back side of the uprights with Zebrano veneers, prior to the half lap machining process. This worked well.

?
The problem with the front edge is that it will be curved. I could not machine the curve until the half lap joints were done. This means that the front edge laminations have to be applied
after the machining is done.

The horizontal shelves sit out from the uprights by 20mm. In the photo below you can see how the shelves are proud, and you can see the laminated nature of the uprights.

My dilemma is how best to apply/trim laminations to the front edge,
between each shelf, on the soon-to-be-curved front edges of the uprights. Gluing will be tedious. I¡¯m thinking of using dozens of clamps like this:
?
?
But how to trim the laminations to length after the glue dries? I guess the flush cut hand saw method is the best one I can think of.

I'm not following the need to laminate the front edges of the uprights? The sides are solid wood, correct? Are you doing it to cover the slots and make the front surface proud of the shelves by
2mm? Color me confused...

Hi FOG:

By way of update, the aforementioned Leitz blade is phenomenal. It cuts as smoothly as any blade I¡¯ve owned which is saying something for such a large
blade with relatively narrow kerf width of 3.5mm. The details appear again here, just in case anyone else wants to consider it as a 400mm blade option: item number 133130, 400mm diameter, 3.5mm kerf. 2.5mm body, 30mm bore, 96 teeth, 10 degree irregular pitch,
ATB.
?
This is the first time I¡¯ve used a blade of this size. The dust it throws off is horrendous; I assume it has something to do with making 125mm and 135mm
deep cuts. My 3M Dustmaster is in continuous use.
?
?
This is very fine dust from a couple of hours work at the saw:
?
In the end, the powered rip fence and associated programming has been gold. I¡¯ve used the special programs on the overhead display a lot, including rebating,
trenching, etc., but I must say that I have not really used the specific programming mode for the Kappa 400. It is wonderful.
?
There are 10 program positions, and each of those 10 has 100 spaces to enter specific parameters that can be called up at the press of an arrow key and
the start button on the overhead display. You can imagine its use as follows. For the first half lap joint, I needed a cut at 125mm deep, at 120mm from the end of the Zebrano board. So for P1 (where ¡°P¡± stands for ¡°Program¡±), number 1, I¡¯ve entered 125mm blade
height, 0 degrees blade tilt, and 120mm rip fence position. It works out that I need the fence (which is acting as a bump stop) to move over 16.1mm to give the half lap width I need, so I¡¯ve programmed the number 2 position with 125mm blade height, 0 degrees
blade tilt, and 136.1mm rip fence position for the second cut (i.e. both shoulders of the lap joint). And so forth and so on for all 7 half lap joint positions along the bookcase upright. After 4 cuts, my rip fence is out at about 1150mm. So at this point
I have to flip the upright end for end and start again on the final 3 shelf positions (working from the top of the uprights). This is made easy using the programming on the Kappa 400. Obviously my uprights all need to be dimensioned accurately which I have
done.
?
I forgot to say that I could not use special programming function which the Kappa 400 offers, where the rip fence can be programmed for a number of grooves
or trenches of a specific width and depth, at fixed intervals. The reason? Because my shelves are deeper at the bottom and much shallower at the top, so the position of each half lap joint on the uprights is of decreasing distance (from the bottom up) and
increasing distance (from the top down). Programming mode made this process easy. Seems like cheating. Comparing uprights at random, and I¡¯d say the 0.1mm claimed tolerance is verified. I¡¯ve used lots of compressed air between cuts to make sure registrations
are accurate, and I¡¯d say the Kappa 400 has worked as advertised. I strongly recommend a Felder powered rip fence as a wonderful option.
?
Anyway, the 3.5mm blade width allowed for 6 passes to remove the waste for each half-lap joint. No drilling, no knocking out timber, no marking lines,
and definitely no chiselling. I¡¯ve decided I can live with the bumpy but regularly reliable surface in the middle of each half lap joint.
?
?
Last night I assembled the first and smallest of the bookcases. It went together very nicely but I think I¡¯m going to tweak the Walnut shelves (through
the wide belt sander) so the fit is less tight. In the picture below, you¡¯ll see the upper shelves don¡¯t seem the correct width. That¡¯s because the uprights have not been curved yet, to reflect the design where shelves at the bottom are full depth (260mm)
while the shelves become less deep by the top (210mm).
?
l¡¯ll use a template to pattern route the curve after I¡¯m completely satisfied with the joinery. And then another tricky part is headed my way: I have
to edge laminate 2mm solid Zebrano onto the front edges of all the curved uprights. I¡¯ve agonised over this because I could not cut the curves and laminate before machining the joints because I needed parallel edges. Adding the solid wood lamination to the
edge after the machining is going to be time consuming and I¡¯m not sure how best to do it. I could apply over long sections to each curved edge (between shelves) and then flush them, but how?
?
-
Router (risk of splinters)
-
Chisel (not looking forward to that)
-
Flush cut hand saw (might be the best option)
-
Cut the lamination exactly to length and glue it exactly in position¡
?
If I used the flush cut handsaw, I could use overlength Zebrano pieces (but maintaining continuous grain) and then not stress the clamping process. I
guess after that many cuts (224 to be precise) I¡¯ll be pretty good with the flush cut saw? Thanks for your brainstorming thoughts!

Thanks David for your vote on the vertical method. I think the clean corners are swaying me strongly for that option. I¡¯ve wondered if I make a very
accurate registration jig and use a small pattern bit (I can get an 8mm dia. bit from across town) to establish the majority of the 20mm flat across the joint, then there would be very little chisel work at all:

¡¤????????
corners squared by the saw blade
¡¤????????
majority of waste drilled out
¡¤????????
shoulder established by the pattern bit
¡¤????????
minor chisel work to finish.

Your jig making has always been a source of inspiration for me. Your lock mitre jig is especially egregious! I absolutely love it. Of course, now I know
I should have made a much larger vertical jig that does not depend on the crosscut fence for registration. Something like what you¡¯ve done would have been much better. Cheers.

Thanks for your ideas. You¡¯re correct about the slotting blade. If I go the vertical machining route I¡¯ll need nearly every bit of the 400mm blade¡¯s

You have rightly identified the time-wasting point of needing to take two passes (minimum) and then deal with the waste by drilling a hole with a forstner

Methodology Quiz
How would you make 280 non-through cuts that have to be precisely machined at 125mm deep and 20mm wide?
?
-
Vertical method as discussed to date using the 400mm sawblade, to make two cuts to establish each shoulder, drilling out the waste, and then A) mark a line and use a chisel to square up the joint,
or B) use a router and small pattern bit to establish the shoulder and then chisel out the corners.
?
-
Horizontal method using the same dado stack that machined the shallow trenches, dado raised all the way up for the stopped cut, and then employ either option A or B above to clean up the joint.
?
-
Rely on the existing shoulders of the trenches (5mm deep on both sides), and use a router and pattern bit to obtain the 125mm ¡°half lap¡± joint, and then square up the joint using option A or B above.
?
-
Something else?
?
I personally can¡¯t see a way to avoid handwork of some kind. The reason why I favour the vertical method (as I¡¯m calling it) is because I can get precise
and square internal corners for the stopped cuts. I find it much easier to clean out the waste if the corners are already established. I have never liked chiselling corners square, even with a square chisel (e.g. Veritas). And I would
hate chiselling 560 corners!

Thanks in advance for your input,
Lucky

I have another more stable jig for demonstrating tenoning on the slider that could be adapted for this also.

Re: Sliding Table ¡°90 Degree Jig¡±
#sawsetup
Hi Lucky,
Thanks for the details. As for your question about trimming the edge banding,?I have not used Zebrano to know how easy it is to splinter with trim router. Would a backing material help? If so, you?could use a second, as thick as possible, piece as a backer. This can be held by std F clamps while you trim with router. You will need to re-clamp for each side though.
