I assume you mean for blasting? I'm not an expert, but I believe that would pretty much destroy the briar. It is far too coarse. Similar to someone posting recently about have a buddy with a blast setup with 300psi and 2500 cfm. You won't have anything left except a pile of briar dust.

That said, maybe one of the pros on here have more insight.

I claim nothing. Even a blind squirrel finds a titanium nut once and awhile :D

Pipeguy, if you ever do try it I'd love to hear the results. I would recommend starting at a very low pressure. And I'd start on a broken pipe or something of the like. Don't waste anything good, as likely it will be pretty aggressive.

I wouldn't waste my time on that, Bob. It's way too coarse. I tried ground glass once.

That was me. He doesn't max the thing out, of course, he just likes not being limited by the machinery or having to wait for pressure all the time. No idea what he actually uses. I'll have to ask. (Now, I'm curious)

I've seen the blasts he does with it. They are truly outstanding. Neither overly sharp & edgy nor shallow/Euro/weathered looking. Very much like Dunhill's best Shell output in the 30's, or what Michael Lindner does today when in a vintage/classic mood.

Just got off the phone with him. He doesn't remember the settings, other than the psi wasn't where the magic lived, but rather the cfm; and the total time needed for a great result was about three minutes.

Very cool! That would scare the hell out of me! I blast at a higher psi than most guys I know and it doesn't even approach 300 :D

Heh, pipe blasted in 1.3 minutes! :D

Ahh, nice. I also have focused on CFM. As you noted, that's where it's at! :)

What about glass beads?

That's what most everybody uses.
