Thread: sand blasting cost.

As far as sandblasting goes it does not cause heat, think of all the air tools you use and the pressure drop as the air escapes, it get cold, similar to the way an air conditioner works. the reason the warpage happens when sandblasting is due to displacement , think of a hammer and dolly, the tiny sand particles push the metal around and if the gun is left to long in one spot it will displace the metal causing warpage and eventually holes. If you set your pressure low, keep moving the gun and always keep an angle on it, it should be fine, the one's that end up botched are guys used to doing frames and heavy metal then think they can use the same technique on sheetmetal. for a $1000 you could purchase an 80 gal compressor and a pressure pot sandblaster, or build your own. then charge $1000 to do someone else s.
