Thanks for the welcome George. Some months ago, I repurposed an old box joint jig into a precise 45-degree miter sled. It produced an experimental project that became quite popular.

Having a shop that has a radial arm saw I never felt the need for a crosscut sled. Mine is set up for very accurate cuts at 90 degrees with clamp on jigs for common miters. The thought of a miter sled was never given consideration until I decided to try some interesting geometrical 3D experiments. Starting with a large format crosscut sled I inserted 4 T-tracks into the sled base. Using these I can orient angled "stops" to produce an infinitely selectable miter accurately and repeatably.  What I have posted here is a small example of more than 30 designs that I have produced. I now try to incorporate only 2 miters (30 & 60) into my designs. This allows me to set the miter sled to 30 degrees and using a miter gauge on my stationary belt sander set to 60 degrees I can cut parts with a bit of XS and sand/trim them to an accurate fit.



Some of my most creative moments have been when I've had to cover up an error in my woodworking.
