Tablesaw Vertical Tenon Jig
Includes the STEP CAD file and instructions PDF.
A tablesaw jig for cutting precise 22.5-degree miter angles on frame pieces, built to make the Flag Display Case. Free 3D CAD model available.
I made this vertical tenon jig to cut the 22.5 degree miter angles required for my Flag Display Case. Standing the workpiece vertically against the jig provides a safe and accurate method to cut these small angles.
Tip… your miter cuts will only be as accurate as your jig. So make sure your assembled jig angles are all exactly 90 degrees!

Using the Jig
Securely clamp the workpiece to the jig, then push the jig forward while holding it firmly against the tablesaw fence to make the cut.
Cutting slowly for the final 1/8″ or so is required to prevent tear-out. As an alternative, applying tape to the workpiece along the cut line can also help minimize tear-out.
