[Woodcarver] Inflatable sanding drums

[Charlie Briggs]

Hey Steve,
We have two pneumatic sanding drums in our club, they are mounted to a 
machine made to spin them so we didn't make it ourselves.
It works great as long as you keep your carving moving around and you don't 
keep it in one place on the sander. If you do the wood will crack from the 
heat generated.
It does have a canvas sleeve around the drum with a air valve that allows 
you to keep it inflated.
It is defiantly the tool for the job. You will need someway of protecting 
yourself from the dust though, it creates allot of dust as you can imagine.
