Default Segmenting clamp

I have been looking at this section and have decided to try my hand at segmenting pen blanks. There were several ideas on gluing and clamping pieces cut at an angle. One remarked that he experienced some slipping of the parts. My grandson and I came up with this idea. I finished it yesterday. It is made of 1X4 pine and measures 9 inches long, base 2-3/4 wide plus 3/4 for the upright piece, 2 ea. 1/4-20 full thread carriage bolts, washers, wing nuts. If I had to do it over, I would make the moveable part the same height of the other side and drill the holes a bit higher for the wing nuts. The odd part is to put finger pressure on the top to align the parts. One wing nut turns OK but you have to hold the end of the bolt up a bit. Got lots of pine so I might make another one later.

Any plans on how to keep glue/adhesive from sticking to the clamp? My first thoughts were to use wax paper pieces.

Wax paper and lots of it. Looking forward to trying it out. Got lots of wood, need to make a jig for cutting at angles.

Like the idea for your jig. May have to modify mine. I use HDPE for my jig. The adhesive doesn’t stick to it.img_6954.jpg

Nice jig.
If you reverse the carriage bolts and put the wing nuts on the outboard side, you will gain more finger space. Also, epoxy the carriage bolts in place.
