For those who don't want the 1/8" hole from the finishing nail in the underside of their piece, the solution is simple. Do the first piece as demonstrated, radiusing the corner, and that becomes the final part of the jig. Then take your actual piece and double-stick tape it to that piece, or make that final part larger and attach a screw-on clamp to it to hold the piece (or a screw and pieces of scrap to serve as a screw-on clamp).

I would like a jig that didn't poke a hole in my work piece.

double tape thin plywood as sacrificial board for the nail hole

Yes, that is what I do currently.

[@alexreid4131]

How do you know where on the work piece to press down into the nail? Also, leaving a hole in the work piece might not be desirable in some situations.

[@David_K_pi]

I agree. But most pieces have a "show" side and a hidden side, so this will still be useable in many cases.

You are so right from Oxford England 🏴󠁧󠁢󠁥󠁮󠁧󠁿

I like simple jigs! Thank you!
You have to be willing to have a nail poke in the underside of your work as I understand it. So this won't work for every project.

Jim’s the man

[@bobd.]

Works well if your project can tolerate a nail hole on one side.

I used 3 sheets of 12"x12" hard board. One has radiuses of 1/4", 1/2", 3/4", and 1". The next begins at 1-1/4" and the 3rd at 2-1'4". When I need a radius on some work, I just clamp the appropriate guide to the workpiece and use my router with a pattern bit. Quick and easy.

Nice and compact

[@Zamboni-0805]

Great jig! Thanks for sharing

[@Peter-pf6bz]

Excellent jig. 10 out of 10.

[@CarSanSoc]

Could you make a sacrificial table like a lazy Susan with different calibrated radii holes and then use double-sided tape to affix the work piece? Thus avoiding the nail hole.

[@itsbenjiii2546]

This is awesome!

[@michaelpatrick6950]

I suppose it would make radii as well as radiuses. :)

[@Wood]

Nope, sorry. Only radiuses.

Working with engineering drawings, I had to accept that one reference feature was a datum and that multiple reference features were datums.
