Homemade Blasting Cabinet - What Board ?

I'm going to have a stab at making a (sand) blasting cabinet for use on a car restoration project. Although homemade cabinets generally seem to be made from plywood I'm on a pretty tight budget so was hoping to get away with either MDF or OSB as they are about half the price. Just want to check if you guys can can forsee any significant problems going with either of these materials and which of the 2 would stand up to the job better.

Thanks

Jim

Can't you find an old washing machine body, or some other *metal* box. Cover the holes with metal pop riveted in place.

Been looking around the back of Aldi again?

There may be food in their skips as well....

MDF dust is V.Bad if you breath it in.

OSB is nowhere neer as strong.

I'd use thinner Ply to save the cash.

Double layer corrugated cardboard works fine (box from a tumble dryer)

Use a few layers of clingfilm over the windows and the light fittings. You can also make the top lid from light white fabric (I used unproofed ripstop nylon) which gives light in and air exhaust.

On the whole though, don't bother. For body tubs you need to take them away and get them blasted. A domestic compressor just doesn't have enough grunt. If you've a lot of aluminium to do it can be worth it, but on the whole it's just nothing like as useful as you'd expect. For smaller components and non-panelwork, use electrolysis instead.

Grit choice is crucial, especially for aluminium, and vacuum the whole rig out between grit changes,
