from experience, sandblasting is a job best left for professionals.
You can buy a toy from any one of many indusrial suppliers, but that is just what you get.
Without a suitable compressor, you literally are just throwing sand at the job and not using its full abrasive potential.
I have had large amounts of steel blasted over the years and at the end of the day, the pro wins out. I have always been more than willing to part with my money on this issue.
I have also sandblasted before and know the process real well. If I were doing it professionally, I'd go and buy a big deisel compressor and 200 lb pot. This goes outside the realm of most hobbyists.
For a shop compresser, a 5 to 10 HP is ideal, if you can afford it go bigger. I'd also look at an older cast iron one as opposed to the Princess Auto or Coleman junk with their cast aluminum bodies. The older compressors are quite servicable as opposed to the cheapies. Keep you eyes open in the paper for them or check auctions.
