Hi, hope this is in the right section, (Mods, I thought it fitted best here but please feel free to move if you think it should be elsewhere). I thought this may help someone out for a one off job where you needed to blast clean a small item.
I am currently restoring some old alloy wheels which had a very poor rattle can paint finish, most of which came off with paint stripper but the recessed areas have a pitted finish and where proving difficult to sand and clean off properly.
Fingers sore from sanding I thought there must be a simpler way, a quick hunt round the garage and found an old shultz gun, £4.50 got me a bag of kiln dried sand and a cut down lemonade bottle made a good resevoir pot.
Hooked it up to the compressor which was set to 80psi, filled the bottle with sand stuck the pick up tube in the bottle and away it went, worked great and left a good surface for priming, thankfully I did it outside as sand gets everywhere and most importantly I wore a respirator and full face visor I can't stress how important this is as sand dust and your lungs do not match. I figure it may work with a flexible tube and a bigger resevoir but I didn't have any tubing knocking about to allow me to experiment. Prolonged use would probably kill the gun nozzle but for a one off job it seems to have not sustained any damage. Hope it helps someone.
