I finally got around to building a couple of lathe chisel holders. The bulk of my “collection” used an idea that I borrowed from other people. I got some 1-1/2” and 1-1/4” black ABS plumbing pipe and glued together 2 rows (small diameter in front of the larger diameter) using the solvent glue that works with ABS tubing. Because every little black tube is glued in 3 places, the plastic “bit” is pretty rigid. The bottom is simply wood with 1” drilled through holes (so sawdust falls through). I used a roundover router bit to soften up the holes.
