[SEL] ABRASIVE BLASTER

[OUR SECRET GARDEN BED & BREAKFAST]

A reply to Jeff Allen about a portable abrasive blaster.

     I purchased a 20 gal. complete blaster from a local Harbor freight store (www.harborfreight.com)
item # 40925.  I also purchased a new air compressor model H4519 from a local Grizzly industrial store
(www.grizzly.com)  This is a 3hp 220 volt unit.  It will produce 9.1 cfm @ 90 psi. (the blaster uses 6-25 cfm)
The problem with the compressor is that it is supplied with a 1/4" quick disconnect fitting.
To get the 9 cfm you will need 1/2" supply line.  I had a buddy weld a 1/2" nipple on the bell end of
the tank, a union on 10 ft. of 1/2" air line connects to the blaster, here I added a 1/2" air pressure
regulator to control the blaster pressure.  I purchased a 80# bag of fine blasting sand ($4.50) from a 
local lumber yard. (they have coarse,fine and extra fine).  I used a painter drop cloth as a 
back drop,clamped to a partly open garage door to reclaim the spent sand.
Hope this info will help.  This system works fine for me, blasted my rusty engine and am now painting.
