Yet Another Segment Cutting Jig

As Zagreb said about blue77’s turned box today – I’m been infected, the epedemic is spreading. Here is my take on the Segeasy sled, zero clearance strip and saw stop. The sled follows their plans. But since I didn’t want to mess with the drilling or cutting the insert on my SawStop table saw, I modified the plans, combining the zero clearance strip and saw stop onto a piece of old hardboard paneling scrap. Fifth picture is the first ring cut with the setup. I learned to finish the cut of of a segment slowly after having one segment get fired across my shop bouncing off one side and landing near the other side. The handmade knobs are padauk.

Any suggestions on setting the stop distance to make a planned outer segment length? When I cut the first pieces I didn’t take in to count the saw kerf.

That’s a nice looking sled! I think I’ll copy your take on the zero clearance strip / saw stop jig.

‘Scuse me for being dense but I can’t see from the photos – do both sleds move? It looks like the blade is stopping the let one moving ????

Hi Colin,
No, only the right one moves.

Socrbent, Great looking sled.

The only way I can see to solve that problem is to attach another block at the bottom which overhangs the cutting edge by the kerf thickness, and then use that to set the segment length.

As long as the block is clear of the cutting part there should be no problem with it overhanging.

Hope this helps.

Thanks for the kind comments.

Colin – The left is designed to be fixed and the right one slides in the right miter slot. The left jig has a lower and upper locking fixture (see 2nd photo for one end of the bottom of that jig). I align the zero clearance strip with the blade and tighten the 2 knobs which spreads the lock strip on the bottom to lock the jig in place. The black bolt has a sloped head that fits the slope of the recess in the lock strip. The slot in the lock strip is off center so as to force the lock strip against the side of the miter slot closest to the blade. This idea comes from the Segeasy site and it forces the zero clearance strip to align the same each time. You can’t see it in the photos but I cut a slot in the top of the black bolt under those 2 knobs so a screw driver can keep the bolt from turning as I tighten the knob.

Bob – thanks for that suggestion. As I see it the outer segment length is a diagonal between the saw stop and the left edge of the right sled less the saw kerf.

What do you think of this idea – make a bracelet out of a segment ring? Have you seen anyone do this before?

I built one like it. I find it the safest and easiest to use. I also made the wedgies to set the angle to cut 12, 18 and 24 segment rings. You did a great job and went one step more by making a stop. You gave me a great idea for the stop and drop off.

Yeah, I’ve seen seg, bracelets but you need to be sure the glue is strong enough, otherwise very fragile.

That is absolutely correct about the dimension of the segment length. You just have to remember to allow for the saw kerf every time you change the setting. If you use my idea then it doesn’t matter if you forget, because the kerf has been taken care of.

Have fun,

Bob.
