I made this lap joint jig for a future project that I’m going to make for my wife. The jig was made using scraps out of my shop so I didn’t have to purchase anything new. The jig itself is made out of 3/4” plywood, screws, plexi-glass, and glue.
When cutting the lap joint, the jig slides along the table saw fence while the jig itself keeps the wood square with the assistance of the spring clamps. The plex-glass at the end acts as a stop and helps keep the wood square when clamping the wood to the jig.

Cool. Looks like it could be used for tenons too.

You’re right Wayne. I could also use it for tenons. I didn’t even think about that when I created it.

I’m a little confused. From the look of the blade you are pushing the board to be cut into the blade. That makes sense but it leaves no support on the back and, IMHO, those little clamps might not be enough to securely hold the wood. I can imagine the blade kicking the board back and ruining the wood.
If you put the plexiglass on the other end of your jig then you would have a little more support.
Just a suggestion. It’s always good to make jigs that make tasks a little easier.

Trust me, those little clamps hold very well. I could put the plexi-glass in the back but I didn’t want to give too much confidence to the screws holding the plexi being that they are fastened into the “end-grain” of the plywood. Either way I would have them clamped down so “six of one and half a dozen of the other” I guess. My design is a modification of a plan I found in one of my Fine Woodworking books and they have their wood in the front as well. If I run into problems I’ll move it.

Do you make one pass with the jig and then trim to the right size or just nibble away at it?
