But the idea that I'm every somehow better off at a lower pressure just hasn't crossed my mind. Because I blasted at lower pressures for years, and it sucked shit.
You guys are probably better pipe makers than me. Usually, after I blast, I don't like the shape in some way. Sometimes I re-shape by blasting a high spot hard, and sometimes I tweek the shape at the sanding disk. Then I have to re-blast the smooth spots. To do so I want to be close, but not high pressure.
Blasting with one pressure would be similar - with my methodology - to having one cutting tool for my lathe. Different pressures for different jobs. Different strokes for...
