Rocky143 Report post Posted January 15, 2022 What leather crafters call bump jigs, wood workers call "positioning squares." They are usually sold in sets of two or four, without a straight edge. I went through Amazon's entire offering of positioning squares and found one, and only one, set of two positioning squares with a straight edge. It is selling for $11.11 with free shipping for Prime members. It is available in 3-, 4-, and 6-inch models. It is the 4-inch one that sells for $11.11. It is orange plastic. https://www.amazon.com/Chiloskit-Woodworking-Carpenter-Auxiliary-Locator/dp/B07F3WTF18/ref=sr_1_258?crid=22MNMD87XVXMV&keywords=ruler%2Bpositioning%2Bsquare&qid=1642256981&sprefix=ruler%20positioning%20square%2Caps%2C114&sr=8-258&th=1 Quote Share this post Link to post Share on other sites
Doc Reaper Report post Posted January 15, 2022 I got mine off Etsy, they aren’t square and they don’t nest well. I gave up on Etsy because the quality just isn’t there Quote Share this post Link to post Share on other sites
Simplejack1985 Report post Posted February 21, 2022 I got a set of 2 aluminum blue ones off ebay for that. Then went to the local steel yard here and had a 8" piece of stainless cut out for me. Then 2 x sets of brass mider gauges off ebay for 7 bucks a piece. I can line anything up now with minimal effort. Quote Share this post Link to post Share on other sites
