Model T Ford Forum: Forum 2015: Blast cabinet quit blasting?

I changed out the media, pick up tube is clear, hose is clear, blowing air but no abrasive. Yes this is a HF large cabinet. Is there something in the gun I should look at or just throw it out and buy a different gun?

Tim, hold your gloved finger over the nozzle hole and squeeze the trigger. This will force air back through the system and usually frees up any blockage. Works on my blasting cabinet though smaller.

Take the gun nozzle apart if you haven't. It probably got moisture in there and clogged itself. I have the same cabinet and even with a drier/separator on it I still get a little moisture that makes it way to the gun.

I have also had debris get into the inlet of the gun too. Make sure everything is cleaned out.

TP Tools makes a better gun for these cabinets, but it also requires more air flow. So make sure your compressor can put out enough air.

Yes I did.

Water in the line can make the media clump up and cause a blockage. When mine acts up, I take the suction line off the gun and blow through it with the air line, like in the second picture below. Do it with the lid closed, it will shoot a guyser of abrasive up from the bottom of the media pile! :-)

If it has the screw on type nozzle, sometimes the ceramic part can be pushed in to far and it wont feed. KGB

I have the same kind, and my gun recently quit working after only 10 years. :-)

I bought a new Campbell-Hausfeld gun from Amazon and like it much better than the one which came with it. If I had known how much better it works, I would have replaced it years ago. Seems like it was only about 20 bucks.

Keith is right, I just checked mine and there is nothing to prevent you from pushing the nozzle in too far and blocking the suction feed hole in the gun. When I replace the nozzle I usually stick a pencil in the feed fitting as a temporary stop to keep me from pushing the nozzle on too far before I tighten down the set screw.

My experience with the HF cabinet is the issue is with the suction tube design, more than the gun. I recommend getting the TIP suction tube.

The new C-H gun I mentioned above came with a way long rubber hose and a new metal suction tube. I shortened the hose and just stuck the tube down into the pile of beads at the bottom of the cabinet. Works great!

IMHO you have too much media in your cabinet. I never put more media in mine than to fill half way up the shoot. My air line often gets a bunch of condensation and that water plugs things up. Holding the blast nozzle shut forces air down into the media and should clear things up. Make sure your pickup line is submerged in the media

Keith,

I think you just hit a home run. I changed the tip and it quit working. I cleared everything over and over and changed media (old glass beads that were now powder) but still nothing. I don't have time for a couple of days but I think you are correct...no suction because tip is in too far. I don't like those tips, they are hard to find, conical in shape and blow out the center. Might just get a new gun after I get it running again.

Thanks for something I wasn't looking at.

Tim Moore

The biggest culprit that I have found is that the media has worn a hole through the pick up tube. Even though the tube is clear, it just doesn't suck. Not a sermon, just a thought.
