While walking my 7 month old one day, we wandered into the library and happened to make our way to the woodworking section (his idea, I swear). I have taken out a few books from them before, but this time I got a good one. For those interested, it was this one . I have used some of their other designs to make projects from this book. I have done a couple push blocks and a featherboard using their designs, most of the time loosely. I subscribe to Woodsmith magazine, but hadn’t seen any of these.

I usually don’t follow plans exactly, tending to modify to suit my needs. This one I pretty much followed to a T. The box joint jig is fully microadjustable with the knurled nuts adjusting the width of the fingers and spacing. It also features a replaceable 1/4 inch hardboard backer board, which leaves no tearout on the back of the joint. It works great! I was pleasantly surprised with how tight and clean I was able to get the joints on the first try. I included a picture of my test joint. Well designed jig which I can’t take any credit for. Wood was cherry, which I had lying around, but any hardwood would work well. Make sure you have a dado blade and a good miter gauge (it attaches to the miter gauge) if you plan on using this on the table saw. It is also able to be used with a router table, but I don’t plan on using it with my router.

Thanks for looking.

Nice Jig Bailey

I prefer using the router table, swapping out router bits is much easier then saw blades for me, I just recently purchased the.
