With this fixture I can make tight, clean production-run miter cuts on my radial arm saw. Those of us who can’t always take time to readjust and tune our saws realize they work out of true. The miter jig overcomes this because any error on one piece is compensated by matching error on the other.

To make the jig, glue and screw two 1x2s to a sheet of 1/4-in. plywood about the size of the saw table. The 1x2s are fastened 45¡ from the line of the saw cut. Care with the orientation of the miter fences improves the device a 45¡ plastic drafting triangle will be helpful. The fixture can be clamped to the saw table or made as part of a permanent fence.

To use, clamp the fixture on the table (or in the fence channel if the fixture has a permanent fence). Cut one piece left and one piece right. Match these cuts, and a perfect fit will result.
