TriStool and Fixture, BenchPilot Ready
This fixture is meant for batch production of the leg tenons in our Tri Stool project. While you can use this fixture with Origin manually, it's even better with BenchPilot! Note this is designed with 1.25" thick hardwood in mind for the stool. Also included in this project are files for the leg profiles nested together; the tenon file optimized for BenchPilot; and a round stool top scaled to fit on the Shelf Upgrade Kit.

When you are ready to cut your first batch of tenons, each leg must be probed for a grid and file placed individually.
