Get the biggest Ingersoll Rand you can afford....SCFM of 20 or better is really good for sandblasting...80 gallon or larger tank...220 volt...use synthetic oil of manufacturer spec....use their electric auto drain deal with an in the line filter/seperator/regulator setup...auto oiler is nice too for the tools.
The use it as much as you want and enjoy...it'll outlast you.
Lord send your Holy Ghost into our hearts and make the desire of our hearts Your Will.
Pro-choice, that's a LIE, babies don't choose to die!!
