In that same puckering vein, I just bought a 16 5/16¡± Skil saw on Prime day for some future beam projects. This plus a chisel would make quick work of some slots but you¡¯d need to do some significant set up to hold the pieces and come up with some jigs for guidance.

Hi David B. ? I love your stack of Forrest Dado blades. That must have made quite some noise on start-up!

Imran,
I dealt with this many years ago. ?I ended up using a 300mm Forrest Dado King on the spindle shaper on my KF700. ?This gave me a slot/mortise/tenon DOC of 5¡±. ? Since your KF700 is configured as a shaper now,
why don¡¯t you just mount a large saw blade on the arbor, build yourself some kind of simple hood for safety, and cut the slots in that manner. ?Successive cuts while raising the blade between cuts should do it. ?You can angle your crosscut fence as required
to get the bottom of the slot angled perfectly. ?

I also have some slot clutters you are willing to borrow if you pay the postage. ?I have a pair of 4mm slot cutters that are 230mm diameter which would give about a 75mm DOC.
I also have a groover that is 250mm diameter - two piece that can be sized for 8-15mm thickness. ?This would also provide about 70mm DOC to the hub area.
Both of those would required a tenoning hood for safety that can be shop built. ?Let me know if this would help.

David,
Thanks for the detailed response. You have reinforced what I have experienced in my trials. I started the project attempting the 4¡± angled bridle slot and tenon and found while cuts were crisp there was slight
variation in joints.
If I can get a slotting blade in 350mm dia, I would like to still give it a try on the saw. None have come up in my searches. S&S top out around 200mm. FS Tool has a 250 mm dia/10mm kerf for $463 but unlike
Felder (300mm-6 teeth) it has 24 teeth. Do you know of any on your end??

You raise a method of work question worthy of consideration. The limits of slot cutters, and machinery are why we do not see large bridle style joints in mainstream furniture and magazines. They have to be
done by hand or else a fair bit of money is needed. Both limit commerciality.?
The issue you raise is similar to my half lap joint problem, except that the inside faces of half lap joints are hidden. Bridle joints are entirely exposed and so any clean up work is there for all to see.
Consequently your scenario is even harder than mine.?
-
You could use a large blade on saw or shaper and cut the inside faces, similar to what I¡¯ve just done on the saw. But you have to clean out the bottoms by hand. Plus doing single cuts takes a lot of care to get right fitting joinery.?
-
I ?would test the quality of your bandsaw cuts in the timber you¡¯re planning on using. I¡¯ve been surprised at times to discover that the bandsaw can cut well enough (smooth enough) for glue-quality joinery but not in very many
species. Most splinter just enough to make exposed joinery like bridle joints problematic. And you are still doing the hand work.?
-
That leaves oversize slot cutters on the shaper with a homemade hood. I¡¯m planning on making chairs with bridle joints and will purchase one or more identical fixed width cutters from Whitehill. I agree that the adjustable versions
are expensive. Getting said cutters, say 300/350mm x 10/12mm will do a beautiful job on the shaper. But even those cutters (non adjustable) add up.?
I think you¡¯re asking the right questions. The solution you choose will come down to how much handwork you want to do, how well your selected timber machines, and how much money you want to spend. Keep us
posted please!
Just use one blade and raise/lower it accordingly. Don't need to spend the money on a dado set for one project.

Thanks Brian. That is an option and if I go that route, I would like to build a tenoning hood to make it safe. Since Forrest 12¡± dado king is ~$700, I thought I ask what others are
doing.

Largest I've done on the saw was a back bevel on a table top using a 12" blade on the shaper spindle giving me right at about 4" of depth. It's scary as hell given
you can't run it in any sort of guard. If you have a 350mm blade and want to try... you can get it done. I think the safer, if more work route, is the bandsaw and clean up the slot on the bottom.

Thanks Brian. Bandsaw is definitely an option. I am trying to find out if anyone is doing this on shaper or saw. If so, how?

Bandsaw... you can slot as deep as you would like. Cut both sides and the flatten out the bottom of the slot.

Hi Brett,
I assume you have more the 4¡± capability on the saw. Do you slot that high on the saw?
I am trying to figure out if I am giving up on this option too quickly, after a few tries. I believe the blade is sharp but I could try it again with a sharpened blade.
I wish I could find a 350 mm slotting blade.

Bandsaw and chisel or sanding block to achieve finished edges where circular blades can't reach.

??Hi Mikelis,
Can¡¯t take credit for the design, following caught my eye:
I should have added that while I can get ~4¡± cut (never tested it) on KF700 with 300-315 mm blade, I only get 3.3¡± on K975. KF700 is now configured as a shaper so this is putting
me at a disadvantage. Therefore, Felder slotting blade does not get me to 4¡± depth of cut.

That looks like a cool design for the stepstool.
Not sure if this helps any, but Felder makes a slotting/grooving blade in two sizes - 230x4 and 300x5 (03.0.030). It would still require multiple passes but perhaps fewer than the
rip blade, depending on how wide yours is.?

I came across a step stool design that requires ~4¡± deep slots. I know there are other ways to achieve the look of an angled bridle joint but these methods require more work. Here
is what I would like to build. 3 pieces that make each side of the frame are 4¡± wide.
Here is a prototype with just under 3¡± of slotting capability. Wood is just pine construction lumber.
I know I could have done a few things to improve the proportions but this exercise has brought up the question about slotting capabilities.
I tried the 4¡± deep angle slot on the table saw (350 mm, IIRC 28 tooth rip blade) but it was a slow process. I imagine it would be even slower in hard wood. This is where I decided
to switch to shaper which reduced my slotting capability to just under 3¡±. For the slot (for stretcher) in the upper part of the legs I rough cut on bandsaw and then cleaned up on shaper.
All this to ask the question, what slotting capabilities do you guys have? At what point do you start thinking of alternative methods? I do not want to add a machine but I could increase
my capability with a tenoning hood. If I go this route, I would like to build one that accommodates a 12¡± dado. BTW, Whitehill makes a 300 mm adj groover but it is over $1K.
