My favorite one, after trying a bunch of them with a drill press, router, other joinery techniques is gonna make Duckie right proud.

Festool Domino I absolutely understand at over a grand it 's price just SUX.

After you own one you will wonder why you spent all that $$$$$ on all those other tools that mostly fail, take forever to use, and don't give anywhere near as good a result. Thank me later.

If you cannot under any circumstances swing the grand, then do what jamsomito is showing above, and make something out of scrap wood. Results will be as good as most of the marketed items sold for a lot of cash. Duh, after I posted I looked up, it was you with the jig. I think you have the right idea if you don't want to spend a lot of cash to get it done.

Pottzie. I imagine a lot of peeps here had that same router, under one of it's many names. Elu, Dewalt, Hatachi, and likely a bunch of other names I have forgotten, or never knew about. It was THEE big boy router design of the 1980's. Like most 15", 4 post, planers, it's all the same tool. I believe at one time I had a dozen DeWalt 625's :-)
