Sand or bead blasting cabinet

Torr · Expert

Looked at these .. needs one hell of a compressor and air storage to run, and too small.

Had a sand / grit blasrer for diving / breathing air test business some years back, grit gets everywhere, had to locate in shed separate from workshops, and virtually "barrier nurse" the damed thing!!!!

Anyone got any experience of these things please?

Can't find much in the way of choice - in fact this is the only contender so far:

Being in the process of removing old harley paint off engine parts, i was well advised not to sand blast said parts as you can never be sure all of the abrasive has been removed from oil ways etc.

I take it you will be using one for none engine parts ?

I think that the meanest medium to use is iron grit and that can embed itself and cause problems.

I think that the firms that do powder coating of frames use sand.

My informant reckons that beads are good on ally engine or suspension parts and unlikely to embed themselves in the item being blasted.

Having done some research, vapour blasting seem to do the trick for engine parts, but you still need to remove any bearings etc.

I have got a blast cabinet and blast pot, it has a huge appetite for air, my hydrovane compressor will not keep up with it. You are very welcome to borrow it to carry out an appraisal.

After taking in the advice here (thanks guys!) and having had a chat with "one who knows" I have decided to abandon the cabinet idea and might just go for the shot blaster to use in a quiet corner outside the garage.....................
