T-nut for the sliding table
I had a custom shop make some steel t-nuts a few years ago after I got?my?KF700sp. Today, I found that I have extra 2 short t-nuts and 3 long t-nuts laying around unused. I use it with Kreg automaxx clamps, see pictures below. As I mentioned before, the automaxx clamp pulls the stock a bit when clamping it. As long as you have the plywood block placed against the stock being clamped, the stock will not move at all. The short one is 70mm long, the long one is 120mm. All have 5/16"-18 thread. I can offer it ($25 for short one, $40 for long one, plus shipping), I am in Ontario, Canada. I can get the shipping quote from Canada Post or your choice of carrier like Fedex and UPS. I heard the shipping cost from Canada Post is cheaper than Fedex and UPS here. If you are interested, send me a private email. James |
Re: Efficient Method to Wrap Plywood with Solid Wood
Can you borrow a lipping planer?? Perfect for such jobs.? To attach, sounds like an application similar to how I like installing face frames, I use biscuit jointer referenced from adjustable plate to plough groove and them random biscuits on the applied edge to freely adjust left/right (it leaves a consistent reveal).? Make sense?? On Thu, Feb 17, 2022 at 11:30 AM imranindiana <imranindiana@...> wrote: I need to make a replacement table top for a friend. He wants ply because he is going to paint it.

Efficient Method to Wrap Plywood with Solid Wood
I need to make a replacement table top for a friend. He wants ply because he is going to paint it. Finished size is 20¡±x53¡±. So plan to use 3/4¡± ply to which I will apply 1¡± wide solid wood edging. Edging will be profiled. Mitered corners for edging. I can round the sharp corners.
I was excited to finally use the MFK to trim edging flush with the top but it can only do 5/8¡± (3/4¡± tops) wide edging. That means I have to clamp a wide board to the edge (for stabilizing a router) and use a flush trim bit. I am thinking of a slot and tenon interface, done on the shaper, to apply the edging. I can offset the cutter by a few thousands to ensure edging will be proud of the top and then just sand it. Does this sound like a good plan? I would like to profile before gluing the edging to avoid blow out (during profiling) and the slot/tenon arrangement sound attractive for that reason as well. Maybe just able to use painters tape to glue the edging. Imran |
#wanted Kappa 400 x motion or advice on purchase
#wanted
Hi, anyone selling a Kappa 400 x motion or advice on new configuration?? I moved from cabinet saws to sliders last year, really like my K700S but thinking more about plans for retirement which is part time cabinetry business.? Retirement is a ways out but so is availability on machines, this would be a 'final' purchase.
Thanks, Jay in Cleveland |
Re: Wide belt grit selection
¿ªÔÆÌåÓýHey JasonHa,? yes you're probably getting better resaw results.? I rarely do it- most of my resawing is really ripping edging on the table saw,? and then? widebelt with 80 at a fast feed rate. It's all about pounding out a ton of defect-free edgebanding quickly. Post edgebanding I hit the edges on the edge sander.? The sine wave seam on an angle plus soft platen does make a difference. It's just not a priority for me cause I'm going to belt sand anyway. I'm about to transition to a stroke sander for that.? The coat of the deluxe grits (zirconia) never seemed worth it.? You know how it is- I figure out what works and then don't really spend much energy engaging in speculative optimizing.? Regards Lloyd? |

Re: Wide belt grit selection
¿ªÔÆÌåÓýHi MarkI haven't found many options for the belt material when buying wide belts- usually 180 is paper and the coarser ones fabric.? Once you handle and use them, this division will make sense.? No need to pay extra to get atypical belt configurations- go with the default.? That article confirms my suspicion that the felt platen does reduce chatter but it's never been a priority for me because I almost always flood the pieces with dark dye and belt sand- this is the best way to catch all the surface defects and monitor sanding progress.This wouldn't work if you weren't going to add any color.? The article suggests that large shops do a lot of belt washing- maybe they're doing a lot of resinous material. For most of my work,? the belts wear down before clogging. You can feel the tooth wearing down.? I apply most of my own veneers and won't run veneered panels thru the thickness sander unless I'm using thick veneers (>1/24"). The cores are almost always edgebanded and thickness sanded before veneering but variations in glue thickness creates high potential for sand thru if the veneers are thinner. I think there are specialty thickness sanders for standard thickness veneer (segmented or pneumatic platens?) There is a high risk of sand thru with standard cabinet grade plywood. Anything with a thicker face ply like multi-ply (Baltic birch) or construction grade ply can work but you have to be careful.? I've sanded nonferrous metals (removing only a couple thousands of an inch at a time), plastics, epoxy and stripped finishes but these materials will wear out and clog the belts quickly.? My attitude is that sandpaper is meant to be consumed. I've also grained stainless but that shouldn't be done because of the risk of sparks/ fire.? The machine is also great for dimensioning floating tenon or spline material.? It is easy the creep up on a precise thickness in a controlled manner.? ?Running the material a 2nd or 3rd time thru the machine without changing the thickness setting removes small amounts. Rotate the material so that unequal belt wear gets canceled out. You can jump a grit size up to 120. But don't skip 120 on your way to 150 or 150 on your way to 180. Those finer belts wear out very quickly.? Regards Lloyd |
Re: Wide belt grit selection
¿ªÔÆÌåÓýJason what brand? I am looking at VSM cloth right now because I can buy a min of 2Butt it¡¯s a butt joint (pun intended)? The zirc is only $5 more per belt But here is the other thing these particular ones are not anti-static, VSM guy said won¡¯t really be an issue for me as a light user and only doing hardwood? -is non anti static ok?

Re: Wide belt grit selection

For your volume of use in a one man shop, I don't think that would pay off. We are using Aluminum Oxide, with 5 people in the shop and belts last months. Here's a photo of the diagonal wiggly seam.

Re: Sliding Table Installation
These pictures are spot on that L bracket and holes for the overarm do not line up at all at least in this picture the holes are partially visible. I am a good 3/8" off I'd say, not a big deal just didn't realize what transpired during service to get it to fit versus what I did which was leveling the table first. I question how important the bracket is too might be better just leave it disconnected.

Re: Wide belt grit selection
Mark,
? I was initially encouraged to use strictly paper backed belts by my Uneeda distributor. In the 7 years since acquiring (Safety Speed 4375), Here's what's evolved: Resawn surfaces aside, I am typically using a spiral planer for s4s prep, then to the wide belt 180 grit with platen, as I only need to remove .010 - .015" . One pass per face ~ .007 per pass, landing within a few thou of target thickness. This includes assembled FF's and doors. While I own many grits, 180 is almost all that's loaded on the machine, and the platen is used 100% of the time. Zero chatter. Slight hula-pattern from belt oscillation, but a quick (1ips) once-over with 180 on a 6" Metabo R/O = ready for a swirl-free staining, as that's typically what the job calls for.? ? Rare occasions, I lift the platen (3/8 felt with fabric backed graphite overly) and let the drum do the heavy digging if stripping finish / veneers off using 80-100 grit. As soon as I hit 150+, platen is engaged.? Cloth vs paper backed: imperceptible difference in real-world performance = I don't worry about it any more.? I've recently read about an SCM user who feels he gets too much of the sanding tracks when platen is engaged for finish sanding in the 220 range, so he never uses the platen. Very strange to me, as the drum alone typically produces chatter lines in my experience. ? = Your experience will evolve to harmonize with the behavior of your machine. Start with a decent selection of reputable brand (3m, Ekamant/Uneeda, or Hermes) in the 80-220 range.? test with / without platen. Steel drum and raw steel platen? Raises an eyebrow, as I have no experience with either.? I'd be wondering if , on a used machine, that the graphite material and felt may have deteriorated, been disposed of, and use of platen completely abandoned. (?) Only other reason would be heavy stock removal on material with irregular density, like a knotty pine, where a soft platen may result in less than a perfectly flat surface. I just feel, for users like us (NOT a high-production commercial enterprise), a properly maintained and utilized platen is a must. Again, YMMV. Jeff |
Re: Wide belt grit selection

Re: Clamps and accessories
??? I will also agree about the problem with the Kreg automaxx clamp.? I have found if you hold on firmly to whatever it is you're clamping as you activate the clamp, you can over power the lateral pull of the clamp. You will notice that the gray plastic clamping shoe will slip slightly where it slides onto the steel clamping foot each time you use the clamp. After a while you will have to push the plastic clamping shoe back into place. I'm pretty happy with the Kreg clamp overall. I made a base for it out of 1/2" x 4" aluminum stock.

Re: Wide belt grit selection
Lloyd,
My resaw setup must be better than yours as 120 is takes out saw marks in a pass or two??We can even glue directly off the bandsaw. I was having bad chatter marks off the sander for a while, it was the belts. Don't use the 3M 340D belts. They are inexpensive and last a while, but they have a straight seam. You want all your belts to have that sine wave zig zag type seam as it greatly improves the finish quality. Jason Holtz J.

Re: Clamps and accessories
?
Wade,
?
What Bill posted is a special nut that is designed to be secured at couple of locations (designed for that nut) in the slider slot to mount the short xcut fence. One does not need that for jigs but it will work as such if one was on hand.
?
I think it is too short if you are thinking of using it with plinth block. Maybe it is not as bad with manual clamps but the clamp will try to lift up in front in use so ideally, you want the Tnut securing the plinth block to the slider in front. This however is not convenient as you want the clamp to be close to the xcut fence. Fence is tall so operating a lever becomes hard. So long story short, use a long Tnut and try yo secure it as forward as possible.

With your set up, can you lock the Kreg clamp to the slider bed, prior to clapping down your material. ?I was wondering if they make a Kipp lever that would match the threads that are machined in the Felder t-nuts. ?When you buy the t-nuts from Felder, do they include the two allen head set screws?
