After my 5″ sanding discs have seen their last days on the random orbit sander, they see new life on the Lathe.
The wood lathe makes a great slow-speed, low-heat sander for quick de-burring of plastic with little risk of melting it. I also use the lathe for sanding sculpted spoons.
I designed an adapter for 1″ x 8 TPI spindles to mount 5″ sanding discs.
(an undersized 4.5″ version is also attached)

This + plywood circle +
- Velcro = semi-hard sanding surface.
- Mousepad + Velcro = squishy sanding surface (my favorite).
- Soft density foam interface pad = excellent for convex surfaces
It prints very well. If you have boogers in the threads, you can clean them out super quick using a 1″ x 8 TPI tap (for tapping wood).
- Finer resolution will give better threads. I used 0.1mm
- PLA works great! I’ve had extremely good experience with AmazonBasics.
- Beef up your top, bottom, and walls…then go easy on infill.
