    We use a 5 Horse Power 80 gallon Coleman air compressor which tops
    out at 90psi.  I would get a higher pressure model next time.  We
    use it for sand blasting as well as running many other devices in the
    shop including a sprue cutter, and car wash style investment removal
    water sprayer.  We have the harbor fright (a rude company which
    makes you send them a letter if you don't want them to sell your
    name) $120 cabinet as wells 2 smaller ones. Buffalo brand from Darby
    dental. Changing the media is a pain so get more cabinets one for
    each media. Getting the cabinet hight right is important.  On the
    smaller cabinets use the thinest gloves you can get away with. 
    Sandblasting with silica sand causes silicosis, so exhaust to the out
    side or use a hepa on your vac.  Buy a roll of view glass protector,
    (lexon?) then cut a supply ofthe right size pieces and tape them
    inside the glass to keep it from wearing.  An in cabinet light is
    very important.  Wear safety glases. 

Blast Off!  
Marty
