Adjustable box joint jig built from oak. This is the jig as found in Shop Notes magazine from sometime ago. Built this to enable me to build 12x draws for some shop storage units, another project in progress. Now the jig is built I can do the drawers!
It has adjustments that enable you to dial in the width and spacing of the slots and pins. In theory I could set-up to build pins and slots 1/8” to 3/4” and anything in between. I added some T-Track to enable the jig to be used at my router table with the appropriate bit, or with my table saw using a dado blade which is my preference from the first couple of tries. There is a sacrificial backer and the work piece sits on it’s own material rest to prevent it having to ride across the table surface on end.
The first try using the router table with some Baltic birch test pieces was far from satisfactory, lots of tear out in fact so much that it blew out the whole piece (even with the backer) probably due to too high a feed rate, or too high a depth of cut. I was specifically feeding slowly, using a 1/2” straight bit. (non spiral)
Second try, using the table saw and dado was far better. The only adjustment to the jig was the distance from the already set 1/2” key\slot to the blade. Very happy with the result.
Thanks for looking.
