I have a sand blasting cabinet that I use with my auto restoration. Can I
use that to blast HO freight cars? Would I have to change the sand out to
what you guys use? I have heard of grit blasting but am not very familer
with how fine the grit is. Would the sand blasting cabinet be just a booth
and use another thing to clean the cars?
Are you saying you use sand for blasting auto parts??
That is REALLY dangerous to your health.
I use 150 alum oxide for car parts blasting, at full unregulated pressure
from my compressor.
That will leave a rough finish on a plastic model. (As me how I know <g>)
For model blasting I use a Badger 260. The instructions say to operate at
30psi and never exceed 80psi.
Badger provide 220 grit alum oxide for the abrasive blaster.
