Re: abrasive blasters
You might be using less pressure or volume but I find the vacuum
necessary to keep the booth relatively clear of being in a virtual
dust cloud. I see much better with the vacuum running and it wasn't
that much of an additional expense. I also attached a vibrator motor
to the underside of the slope sheets to help recycling of the media.

doesn'tAlso get a shop vac to evacuate the air and keep the booth under
anhave a connection for this, you can make one and bolt it over
shopexisting vent on the booth. Note that this vent must also have a
breathingvac. And for further protection, use one of those dust filtersI haven't found any of this to be necessary, either, though
through a dust filter is obviously a good precaution. I have aclear
plexiglass front on my sandblasting booth in which there are twoarm
holes with elastic cuffs cut from a cheap nylon jacket, so theabrasive
powder can't escape from the booth. Seems a simpler way toconfine the
abrasive to the booth than what Mike is suggesting, but YMMV.
