I need to make a large frame for a hybrid presentation panel, and have decided to use the mitered half-lap for the corners because of its combination of appearance and strength. Problem is, I’ve never made one before and there are apparently a zillion ways to do it.

I watched the Woodsmith video that describes the table saw method, and went for it. Tried it with some small scrap, just to see what I could do, and, well…it’s right ugly. gaps in the miters, overlaps or gaps in the lap portion, noticeably out of square.

This is apparently a joint that takes some practice. Anyone feel like offering some sage advice to a first-timer?

Before I had a shaper and a lock miter cutter I used a stacked dado cutter to make that joint. The secret is ; just a little miter and a lot of lap. The only reason for the miter is to make a joint with no end grain showing, First set your dado at a 45 degree angle and cut the miters on both halves with the stock flat on the saw table/ What will be the inside of the joint should be flat on the saw table. Now move the dado back to 90 degrees and cut the lap joints.
