I realize this is an older post, I am curious as to your sandblasting set up. I am somewht confused over the siphon vs pressure pot systems. I have a compressor, 7CFM with 90psi. 4 HP and 11 gallon tank. Most cabinet set ups want 11-14 CFM, then I found an article about using a smaller
nozzle to compensate for lower CFM. I have looked at tptools and northern tool, harbor freight and Grainger and texas blaster. Any comments/suggestions welcome.
