Blast cabinet

[Rob Lafferty]

Guys

Was looking at buying a small blast cabinet at the weekend and the spec says that it needs 10cfm. I only have a small compressor with a 25 litre tank and 2 hp motor (8cfm).

Question is will i be able to do small parts a bit at a time or am i wasting my money ?

Thanks

Rob

Rob, I think you will be fine, you'll just have to pause now & again to let the compressor catch up.

Rob, have the same size of compressor with asmall cabinet , only added a water separator in the line. Cabinet was some 90eu complete with lighting, pistol etc.

Rob, if you want to do it on the cheap, as I did, but a 80ltr clear plastic box (with no handle holes etc in it), they're about £6, then buy a picture frame about £6, with a perspex front, big enough to cover the top of the box. Put two arm holes in the front, buy some heavy duty marrigolds, and pad them out to form a some sort of seal at the holes, and viola (as the frog says). There was plenty of dust but saved a fair bit.
I used a 2.5HP and a 50 ltr pig, to run a cheap syphon blast gun, and it did the job, just. You will be waiting for the compressor to catch up quite a bit though.
It may sound obvious, but try and get as much of the crap of first, i.e. thick grease, and if you lightly scratch any paint thats left on, it will help the media get unde it to the metal.
