Jim's diamond pattern driver inspired me to try some similiar.
Walnut blank drilled with 1/8" holes at an angle to the blank. Inserts are 1/8" dunno dowel stock.
Have a couple of holes that are not in line. Bit walk I guess.
If it doesn't work, it will be kindling.
Next is some of that scrub oak burl I found in the woods.
Seems fairly dry so I'm going for it.
