Ryan, David,
I also have a TIP pressurized sand blaster but I use a product called
"Black Beauty" that I get from my local brick yard and it costs about $6.50
for an 80 pound bag. It is a coal slag product. It comes in three
different grades. I think that the grades are very fine, fine, and medium.
I use it to do all of my blasting from frame to sheet metal such as oil
pans, flywheel covers, valve covers, etc. as well as the cast iron parts.
I also capture it similarly and do the same kind of filtering. One the
things that I like about it over the sand is that it lasts longer and it
does not produce all of the dust that sand does. Besides using the proper
size nozzle the other critical thing about clogging is humidity or moisture
in the media that you are using. If possible you need to put a drier on
the air line out of the compressor to remove all of the moisture before it
gets to the blaster. I used to use ceramic nozzles but have switched to
carbide. They are more expensive but they last forever and don't break
when you change sizes for the different size blasting media. Yes, yes, yes
use a good respirator.
