And the finished product. Any discoloration you see is Fluid Film.

Plenty good for working on guns, and stuff.

I used to have access to a huge commercial cabinet at a local aerospace contractor. I LOVED that thing. It could be set to "cut your hand off" or "clean the tears off a baby". And everywhere in between.

My cabinet is about 15 years old and I need a new gun soon. It has lasted way longer than I ever expected, and I use it all the time.

We've got one that mid sized hooked to a 200 gal compressor set at 180 psi. There is a regulator so I can turn it down but our cabinet is full of glass beads which would probably be too agressive.

Looks like you did a great job.

Did something happen or is my computer being a douche?

Really? They show up for me. Weird.

They're showing up for me now but there was the Photobucket thing in the squares when I wrote that. I'm getting tired of their tech issues. They happen entirely too frequently.

Thanks!! High praise from a master machinist.

I used to use glass beads. They gave a very fine satin finish which I love on stainless guns.

I switched to the aluminum oxide because it was supposed to be very aggressive, and I was doing mostly Glock frames. Takes the shine right off a poly frame. In your cabinet it would probably cut stuff apart.

I've got a frame and slide I'm going to need to blast sooner or later....I wonder what pressure I should set it at? 40lbs?

I think I used to use 35lbs, but that was with the glass beads. The max on that old compressor was 50 IIRC. I think my current one goes to 70. Does that seem too high?

Start low and work up, I guess.

Now I gotta check the PSI and CFM to find out.

Maybe I'll start at 20. If that doesn't get it clean enough I can move it up. I'm still amazed how soft gun metal is compared to automotive materials.
