It just occured to me, I have a huge collection of little drum sander bits and sanding drums that I bought for my dremel.



I bet they would go into my pillar drill setup, it may not be the perfect plan but I think I could probably make it work.

While I'm thinking about it, I also have some of those little wool and felt buffing attachments for my dremel so clamping it sideways in my vise gently might make an adaquate buffer if I'm careful until I can afford a proper one.
