The great part is I can blast clean all the way up into the suspension towers and behind the spare tire well between the frame and well.

wheee, is the copper slag taking it down to bare metal, I can't tell from the pics?

Chris

[wheee!]

Yes, it is right to the metal. A somewhat rough finish that will bond well with the POR15 when I get to that stage....

It looks dull compared to the section of tunnel that I did with the EZ Strip wheel...

If you look at the amount of asphalt residue left on the park brake assembly behind the RT mount, then look at the pic below where it has been sandblasted, the difference is night and day!

Okay, I see it now, I didn't think copper slag was that aggressive. I'll give it a try, god knows my lungs can't handle anymore sand.

I am actually quite pleased with the minimal amount of dust being generated. I use a face mask of course, but I would not want to use sand under any circumstance! Plus, I am glad I am not using the crushed glass as it is so fine, I would be worried about breathing any of that in!

I'm jealous of your rapid progress.  I had nothing but trouble blasting.  My compressor just couldn't keep up and it was an exercise in frustration.  I'm glad to be done with it!

Great looking work going there. I had one helluva time with my siphon set up at first, moisture from the continuous running compressor. I bought an extra moisture separator that goes before the gun and hung the bucket from the ceiling so it wasn't sucking as much, more or less falling down into the gun. Worked good with coal slag for a rougher finish. 

FWIW

lol, I'm jealous of your level of completeness! I am glad I have a 18CFM 60 Gallon. It runs non-stop almost while I'm blasting but pressure never drops below 100psi. I let it rest every bucket refill. If I stop blasting for a minute or two it catches up and shuts off.

I bought the moisture separator from Princess Auto and it has been fantastic. Removes all the moisture in the system.

That looks to be one fantastic separator you have there. Never have I seen one like that. I google it and see about getting one for myself, nothing more important on my type air work. Great info!

Thanks!

If you have your shop plumbed for air, it is important to give yourself a water trap and drain.  Here is an example that we use at our local workshop.  The ball valve can be cracked to drain the water from the line without removing the air hose.  The trap also keeps water from accumulating when not in use.  Sorry for the sideways pic.  It is correct on my computer.  The forum is turning it for some reason.

 

 

[wheee!]

True. That is why my air dryer has the big ball valve at the low point of my system. It allows me to close the ball valve at the compressor, then open the ball valve on the drain every night. Several times a day while sandblasting too...
