I did mine with a pressure blaster, 2 stage 110v compressor (maybe 30 gallon)... NOT BIG ENOUGH!

It's all about the CFM's as stated... 220v 60 gallon or larger... I needed to maintain a constant 90 pis to blast and mine averaged 45-50ish.... it was like taking a pencil eraser to the frame...

I suggest taking it to an industrial shop in your area to blast, might cost a few hundred but they will do a better job, for nearly the same price and much less mess...
