I have made box joints using the router table, and the Leigh jig methods. The Methods of Work on box joints (FW Issue #214) has a tip on building dedicated jigs for making box joints on the tablesaw. I decided to give it a try and after a few hours in the shop today, the 1/2” box joint jig was made and the results (using scrap 1/2’ plywood) were very satisfactory.

If you’ve built a cross-cut sled before, this jig is as easy to make. I cut the runners an hair thicker than the miter slots and used a cabinet scraper to size them to exact thickness.

You can see a couple pairs of spare runners I’ve made. I plan to make one more box joint jig for the 3/4” stock.

If you don’t have the issue #214. go to here to see the interactive instructions:

The published tip is here:

(Note: The above pages are free for now but may require membership to view after a while.)

If you search ‘box joint’ in FW’s site, half a dozen articles/videos will be retrieved.

Cost of this jig: $0 as everything including the wing nuts and bolts was from the scrap bin.

Happy finger-joint making.

P.S. If you don’t want to build a jig, you can adapt this for use with your miter gauge.

You have a very useful jig there Chuck, and I see it is popular too being favorited 10 times already. I have a few projects coming up for Christmas presents that this would come in very handy for. Thanks for sharing.

Nice jig Chuck and good results as I can see. I believe you didn’t get any tearout since your plywood test pieces were well back supported, compare to a router jig, right?

Thanks for posting and thanks for the links.

Best,

Serge

PS: There is such jig in my Diary Book that should come out some day!

I want to use finger joints for my kitchen drawers, so I I have been looking for a nice, easy, safe and moron-resistant way to make the joints.

Then I stumbled upon this post and the Fine Woodworking jig.

Now, I could go into great depth describing some of my mis-steps in creating the jig (Just make sure you don’t screw the thing together along the centerline….you’re going to want to saw right through there….

BUT, the proof of this jig lies in the following picture…first try, perfect joints!

It’s gotta be the tool, it can’t be the operator.

I hope this is helpful.
