Keytop material?

[Farrell]

John: Look in your PTG Journal on CDs. Bill Spurlock did an article complete with detailed plans on how to build and use a blast cabinet. Beads are glass as I recall, cabinet is on wheels and can accept a complete large grand action. I have long wished to have one - just haven't found the time to make one yet. Dave Schwartz in St. Paul, MN had one in his shop when I was there a few years ago. Pretty impressive how it can clean up a scuzzy old piece of wood real quick. IMHO, especially for someone doing a lot of action work, one of these cabinets would be a real asset.
