Biscuit joiner for irregular shapes

I recently had the need to secure a top to an irregular box using glue and biscuits and was successful using careful measuring BUT the following idea came to me. Why doesn’t someone make a biscuit positioner similar to that used to position the mating dowel holes. For doweling it is a simple metal dowel that has a ridge and a centering pin. For a biscuit it would be about 60 percent of the curved part and three pins that would show where the mating biscuit cutout should be. I passed this idea on to Rockler product development this last week so we may see this become available.

Good idea Abe. I have a biscuit joiner, maybe your idea would encourage me to use it more.

I went to El Camino high school in North Sacramento about 55 years ago. Spent some good times at Folsom too
( the lake, not the prison). Haven’t been back there for about 50 years. I’ll bet it’s changed a lot.

One other way to do it is to take a biscuit and cut 1/3 off of a side. Slip the other side into your already cut slot, and cover the cut edge of the biscuit with chalk. Place the two boards to be joined together and give a light tap with your hand, you should have a nice mark to go with; if you want you can then help it stand out with a pencil.

Couldn’t you trace 1/2 a biscuit on a piece of metal with matching thickness and leave a little nib for marking in the center? Either that or cut a wooden biscuit and drive a nail in the center, clip off the excess and file the edge to a point.

By the way, I am picking up a Makita 2030 planer/jointer on Monday. What did you use to replace your feed rollers?

I could make the biscuit slot marker but thought it would be nice if a manufacturer did it and marketed it for a reasonable price.

I got replacement rollers from the local Makita repair facilit. As I recall they were about two hundred but worth it.
