I have a vacuum blast cabinet. Probably a good unit, but older now.
The vaccuum system is a bit touchy, I imagine a pressure system is better. I find it painfully slow. I have a 12 cfm compressor. It is about the biggest single phase unit on the market and it runs out of puff very quickly. You need a 3 phase compressor or a diesel powered outfit. The other thing I could do, is to hook in a second compressor.
Anyhow Lionel, my advice is to take your chassis, wheels, and other big bits, to the commercial people. Otherwise (I believe)you will decide that your life is too short to waste it holding a near useless gun for hours and hours.
In support of Tony's comments, It is illegal to use silica sand for blasting in N.Z.(in a business situation)
I'm not saying dont buy that set up. You can do the small stuff that the commercial guys might loose while they are trying to chase it around the floor.
My outfit managed to loose one of my carrier suspension springs. This was years ago, when they did it outside. That doesn't happen any more.

Sorry Guys. I don't know why the pictures are upside down (i'm not trying to favour the northern hemisphere guys)
