blasting

[jtd.75]

there is guy that that I know who use's ordinary builders sand when he is shot! blasting cars when he is doing any restoration work. he tells me the secret is make sure that the sand is bone dry by taking it in doors and letting it dry out then he puts it through a seive (i think thats spelt wrong) a coulpe of times and he says its a hell of a lot cheaper and in his opion it does a better job

kiln dried sand which is what u brush in your block paving is better i would think, might try it myself later, but there is a safety issue ,good mask needed,steve

There's a huge health risk. I looked into this a while back and after some reasearch found that the using any type of sand means tiny glass particals become air bourne. This glass can penitrate some maskes and irritate the lungs and they become inhailed. I would pay for the proper gear and get the peace of mind.

Hello Jtd,

yes, I agree with Paul, I'm almost certain that it is illegal to use natural sand as a blast medium. (Obviously that applies to comercial operators, what DIY people do is not so regulated, but it makes sense to follow the guidelines.)

anyway theres an old filing cabinet at work, if i were to get my rivet gun out and make a cabinet , would that reduce the risk of using sand with a mask also?

It could help contain the dust, if well sealed, but you still need some way of getting rid of it safely and sand, when smashed up gives sillica dust which can give you sillicosis of the lungs (fatal). Once thing you could do is seal the cabinet, and create some kind of extract (I had the idea of rigging up an old vacuum, such as an old dyson would be ideal), to remove the fine dust, keep it out of your garage, and enable disposal.

You'd still need the big thick rubber gloves and the perspex viewer.

Yes, obviously wear a mask where any dust is being generated. But there is no guarantee this heath robinson contraption would work, its at own risk!

Frost do one, but as usual it aint cheap

If you can wait a couple of months, they have a blast cabinet on the resto course I'm on, then we start "private study" which means we have completed the syllabus and can start bringing in our own bits and pieces, I could blast a few things for you each week, what do you have in mind??
