Topic tags/keywords: tip box joint jig set up

There has been a lot of recent interest and discussion of box joint jigs and how finicky/tedious they are to set up. I very meticulously set mine up the FIRST time and then cut some very hard wood scraps tweaking it until I get perfect joints. Then I keep the perfect pieces and just use them for subsequent set ups. No measuring or fussing. I hope this helps someone.

WAY TOO SIMPLE … gotta buy some high $$$$$$ jig … SHOOT … let’s just save up a BIG bunch of $$$$$$ and go CNC …

Oh … that IS a great tip, and one I’ve used for decades … thanx for bringing it up. Setup bars/blocks/samples are always a time-saver.

Absolutely a fine idea Andy. A setup block per-say. Yup

But better than set up blocks/bars because it straddles the index pin and BOTH sides of the blade or bit!

That technique will certainly work. The more care you take in jig construction and setup, the better chance you have of success.

Remember, however, depending on the jig and what cutter you use (dado on a tablesaw or straight bit on a router table), you may have 3 settings to make- (1) cutter size (same chippers, same shims, carefully stacked with the same torque on the arbor nut), (2) guide pin width, and (3) spacing between the guide pin and cutter. A carefully constructed and calibrated jig can give bad fitting joints if the cutter is not the same size. Plus, you may need to set everything each time you change finger sizes.

The problem is that if I ever get perfect pieces, I would probably frame them.
