Sandblasting media

[Jordan Baker]

Thanks for the info. I didn't know it needs an extra vent. Is it a must?

I will set it up tomorrow and try to give it a wirl on the weekend. I can't wait to try it out as I have never used a sandblaster before.

Hi Jordan,

You've figured the air you're pumping in has to go somewhere. If you don't vent the cabinet by a powered means, after a very short while you can't see jack in there because only a fraction of the dust leaves with the exhaust air. Try it - if it's a problem go from there. Buying or building something to create some suction is probably necessary.

If you live in a high density housing area I'd reconsider ejecting silica dust into the air outside. If plenty of room then not such a problem. Just be sure it can't circulate back into your home or shed. I'm considering building a water sprayer unit to direct the exhaust thru so the particulates drop out of the airstream to form sediment. Depends entirely on your surroundings.

Some people use silica sand and bugger the consequences, others pay good money for Garnet which I've been told is not toxic. You can buy glass beads from a blasting media distributor, and even crushed wallnut shells, possibly plastic blasting beads, etc, etc.

Glass beads probably good idea for aluminium items.

Have FUN!
