Looks like others have already beat up this topic pretty good, but I'll add my own two cents just because I've been tinkering with something similar recently. Someone gifted me a set of spindle sanders with a standard 1/4" hex bit on each one for use with a drill. I chucked it up in my hand-me-down & junky Harbor Freight drill press and was very disappointed with the material removal rate. I couldn't apply much pressure without the chuck deflecting against the piece, so I couldn't get a good & square sanding surface against the work. Add to the fact this junky drill press of mine already has what I would guess to be several thousandths worth of runout, I stopped before I really goobered it up.I'm still working out the plan, but mostly it involves attaching some kind of a thru…

Add to the fact this junky drill press of mine already has what I would guess to be several thousandths worth of runout, I stopped before I really goobered it up.I'm still working out the plan, but mostly it involves attaching some kind of a thrust bearing to the end of these store bought spindles. The thrust bearing receives the downward force from the drill chuck would help keep the spindle from flexing when you push the material against the paper. I could either build a small table for the drill press with the bearing in it already and just firmly seat the spindle against it, or could attach bearings to each spindle and seat them in a jig with a hole drilled to match the OD of the thrust bearing.

Careful with having someone at the store cutting your sheetgoods on their panel saw. I had someone in an orange apron rip a 4'x8' sheet of plywood into two 4'x4' sheets for me and while the cut started right at 4' mark, it wandered about 1/4" towards the other end. Fortunately that was OK for the project I was working on, but it was a lesson in checking the work of others. Especially when it's your money being spent.

Heh, after a couple uses of a fresh wrench, I end up doing the same thing with moly grease instead of paint!
