I see the thread on blasting cabinet. Very useful as I would like to get
one myself. What would you guys recommend ( if at all ) for using a
cabinet
indoors. Is this safe? Is there a special cabinet or a special one you
might recommend?

Thanks

I did not make clear the use of a squirrel cage blower in my response to
the question about blast cabinets. Blast cabinets are generally intended
for indoor use, but they deal with the dust by running large industrial type
vacuum cleaners with filters, which I found to be a complete nuisance. As
a result, I ended up using a squirrel cage blower that moves about 100 cfm
of air, and venting it outside via a dryer vent. That, of course, is not
good for those that may live in tight quarters with their neighbors. I am
located in the center of 5 acres of land with no neighbors to complain about
the dust created, which can be substantial, depending on the abrasive being
used and the item being blasted.

Yes, you can safely use a cabinet indoors, even with the vacuum units
provided. As they run, they get better and better at filtering because they
start getting clogged with accumulated dirt. That feature, however,
eventually limits their ability to handle the amount of air necessary to
keep the cabinet from leaking. That's exactly why I don't like them.
Direct venting outdoors is the best scenario if you can do so.
