I have done a lot of sand blasting for many years and I,ll tell you what it takes to to have a sand blaster thats worth having. First you need at the very least is what we call a TRUE 5 hp. motor on your compressor. That motor will have 3 capacitors on it and need a magnetic starter to start it and the motor is about the size of a 5 gal. pail, not the size of about a 1 gal jug of wind shield washer solvent like you see on these compressors at local home & improvement stores that even rate them as high as 7 hp. although they are decent compressors for the money but they WILL NOT make a good sand blasting compressor. Second Thing, the compressor it self NEEDS to be ALL cast iron NOT aluminum that means the head and the cylinders. A compressor like that runs around $2.300 new with a 80 gal. tank here in Michigan. THIRD , the blaster it self, really the only thing you want is a long hose (about 10 to 15 feet) and what is called a dead man gun/valve with a CARBIDE tip not ceramic. Ceramic tips are cheap but wear out far to fast. And the last thing is tip size don,t even think of using anything but the smallest tip which is a 3/32 size with this size of compressor. believe me when I say I know what works and what dose not work because I to learned the hard way a long time ago
