At 45 degrees 1mm of slide travel will take 1.4142mm from the diameter. You might recognize that as the square root of 2, or 2 * cos(45). To do what you want, you need the angle to be 60 degrees, cos(60) = 0.5. In your example a 1/4 turn of your 1mm pitch screw takes you from 116.24mm to 115.90 a difference of 0.34mm if you multiply 0.25mm by the sqrt(2) you get 0.35mm so your jig is within about 0.01mm of what it should do, that is really good. But to do what you want to do, you need to change it to 60 degrees from perpendicular to the sanding disk.

Chris Woodhouse I understand why 45 degree isn’t 1:1 ratio, but why then is 60 degrees? It seems to me it would need to be 90 degrees.

Oops, coffee kicked in, and I realized that the if the adjustment brings the piece 1 mm closer, it reduces the size by 2 mm. I’ve been turning for 9 years, you’d think I would know that. Now I understand why 60 degrees.

This is brilliant. Could you come up with something similar for doing kumiko strips please! I tried, but I don't have your skills. I also don't quite get why you need it for the spindle moulder fitting, could you explain the context a bit? I read the blog to find out but still not clear on this.

The spindle moulder set up can be seen prominently in this video- kzbin.info/www/bejne/iZTdhZ6cnLGonJo and i made the guide ring set up in this video- kzbin.info/www/bejne/n6eWap1ujM2Josk The kumiko question is interesting and could be tricky, most of the Kumiko ive seen uses a separate jig for each angle, to be planed by hand and sometimes have a depth stop but it would sure be quicker if something could be made for the sander. Ill have a good think about it, id love to have a go at Kumiko!

thanks @@garychance4494 The sled for cutting the grid work is useful, and I did use my table saw to do them like this, but my question was more about cutting the little inserts for the Asa No Ha pattern. These have 67 degree angles etc and although one can cut them with planing jigs it somehow is a pain and not always successful, even with a very sharp plane (unless you happen to be Japanese!). Hence the idea of using the sanding jig.

Tommy, yes, I agree w/ you. But ….. I learned drafting many years ago and still have a set of drafting tools (a pain in the butt), and then I learned AutoCAD. Build your drawing in layers and the cut sheets just fall right out. Want accuracy? Build it in CAD. Want some strange angles? CAD. Absolutely has to be dead on? CAD. A crutch? You bet and a damned good one!

Question on Sketchup please, and thanks in advance for your time. Is that the free version of Nanosoft/NanoCad? if so, how is that working for you? This is something I've been eyeing in lieu of AutoCAD. If you haven't had any major bugs, I'll probably give it spin. Thanks again.
