I use biscuits a lot in my projects which are small and everything has to be very precise. Was having trouble w/hand holding Makita 3901 joint cutter. Made this very simple jig which is a piece of MDF about 18” long. Set the cutter on the MDF and push a block (appx.3/4” by 7/8” by 6”) thight on either side and screw them in place. Install a 1/4”screw stud in each rail toward the front. Use these to hold a small metal lock down clip to keep the cutter from tipping up or down. You can clamp the back of the tool to the jig with a quick clamp. Put two sets of holes w/nut inserts to mount the lever lock clamp in different locations. Maybe the pics will tell it better than me. This thing is quick to make and easy to use. It works for the items I make most. #1 the jig #2 with cutter mounted #3 angle cuts #4 edge joints #5 end cuts #6 vertical w/90 degree brace It is possible to shim the cutter base or the work piece to get the slots just the height you want them.

I like your jig! Holding everything in place to make the slot is always a challenge. I will copy your idea if you don’t mind…:)

That is a great way to get real performance out of a biscuit jointer. Great little jig!

When a great idea is shown, the true woodworker is drawn to it and is heard to say now why didn’t I think of that… this one of those times… well done…
