Mortise and Tenon via a router.

Well, you could either use a chisel to square the corners of the mortise or a chisel to round off the corners of the tenons.

-- Gary, East TX -- The longest journey begins with a single step.

I’m in the middle of building my first mortise and tenoned piece and have done 36 joints so far. I was thinking of going the plunge router route; made a nice jig and all; but in practise I found I kept overshooting the ends and the cut just wasn’t good enough (too much play in the router I think). So I decided to use a forstner bit on the drill press with a fence to guide the hole in line, then I cleaned up the rest with a chisel. Seems to work better for me.
