Like many I don’t think the quill of a pillar drill is suitable for sanding. I would be loath to tie up the pillar drill to do bobbin sanding, if I was that much into woodwork I would look at a dedicated machine.
I did build a miniature linisher recently, I liked the look of the Proxxon machine but thought it was expensive for what it was.
So I bought the belts for their sander and made a bench mounted linishing deck.
Power comes from my Foredom bench polisher via a flexible drive.
