I've read several discussions on the merits and methods to clean up the interior of hollow turned pieces with a small opening. I've read about sandpaper on forceps, the different Velcro-based sanding systems, inflatable sanders, getting your child's fingers in there, etc.
I was wondering if anyone had used sandblasting media, small stones, shot, or Metal Vibrator/Tumbler Resin Abrasive media inside a slowly spinning hollow piece.
I was thinking I could 1. turn a hollow piece, 2. partially fill it with the media, 3. tape closed the opening, and 4. let it run for a couple of hours on a fairly slow speed.
Has anyone tried this?
What are your thoughts?
