<html> <body> Help - There was what I think was a recent discussion (or at least mention) of bead blasting cabinets, where someone mentioned Harbor Freight Salvage as a possible source of an inexpensive unit.  I have been unable to find that discussion.  My question though is for anyone who uses this process.  The manual seems to strongly emphasize respiratory precautions.  Is this, in fact, a real concern, even with these smaller units? Also, what's the best material for cleaning action parts and screws? Many thanks - David Skolnik</body> </html>
