get the bigest one you can afford so you can fit things like wheels in. and i hope you have a good air compresor. a sand blaster will kill anything less than 5hp
Yeah, the cabinet would be kept in my aunt's garage... my uncle had gotten a 50 gallon (or bigger) air compressor at one point that I would use. I know it has more than 5hp as well so I should be good to go with that one. I will go look tomorrow though to see how big it really is I guess.
