We are redecorating and it's up to me to produce miles of trim. I bought a load of nice 1 x 4s, but I really needed 1 x 2s and ½ x 2s. There was a lot of ripping to be done, and I wanted it to go well. This jig was a big help, so let's go.
You will need a scrub brush, some scrap plywood, a pair of screws, a utility knob, and a functional workshop.
Step 1: The Business End
Step 2: Make The Board Parts
Cut a strip to compression fit into your saw slot and wider one that will span the distance to the blade. It would be good to make that width have something to do with the width of your brush piece. But don't waste any time measuring.
Then cut a slot to slip the bolt on your knob. Center-ish and parallel-ish is good. I used a router and did a really bad job. It didn't matter.
Step 3: Connect The Pieces
Once again, center-ish and parallel-ish is good.
