Tenoning Jig

I made this tenoning jig as what I thought could be a solution to the 22.5-degree angle required for a flag display case. I have a right-tilt arbor on my tablesaw which necessitates using the jig in reverse—moving the fence to the left of the blade.

Maybe it would work for someone else, but it didn’t work for me for that purpose. I still could not get a correct angle close enough to be worth the bother. I ultimately rough cut the angle on the bandsaw and then sanded it to perfection with this sanding protractor jig that I made.

I hope that I’ll eventually get some use out of it for cutting tenons! Meanwhile, it works really well as a fence for taller pieces.

Nice work on that jig. Necessity is the mother of invention and if it woks for you, it is top shelf!!
I do the same all the time to make work easier and some time the only way possible with the tools I have!!

Cheers, Jim

Just for giggles, and to see if your jig could work on the steep 22.5’s you were looking for, try one again.

This time use your clamp you built in, and also use a C Clamp, or some type of hand use clamp on the top, front portion of your stock. Put the clamp over the top/front edge of the stock, but clear of the cut line. I think you are just getting motion from that part of the stock, and it’s messing up the straight cut you are looking for. Anchor it down at the leading edge, and then if it’s strange you may want to look at your method for setting the angle.

Your protractor jig on the disc sander has great promise.

Nice job.

Put a ZCI on that saw now!

Looks like it should work. I like how it rides on the fence for safety. I have a similar table saw jig I use for cutting bevels and making beveled picture frames.

Like Steven said, sometimes the angel of the blade is tricky to set.

That Protractor Jig is cool. Maybe you should have called this project The Disk Sander Protractor.
Where did you get the giant protractor on the jig?

Thanks LJs for your comments.

Steven, when I have to make another steep angle, I’ll try your idea. I did use my digital angle guide to set the 22.5 angle so that part was correct, but your idea could help solve the problem.

Madmark, I keep telling myself I need to make a few ZCIs, but keep putting it off.

James, I just typed in protractor image and picked the one I liked best. I had planned to laminate it but never got around to it. I had to split it to get it accurate with the pivot point.

Nice work on the jig. Those precise angles are tricky ;-) I don’t do enough of them to ever get there.

Bob,

I haven’t “arrived” either, and probably will never get the angles just right, but the protractor jig did help me get a bit closer.
