TCP Global Gravity Feed Sand Blaster Gun Kit

It is actually a pretty good product for the price. If you search here there are other ones but most are the same sold under different names, When i see that i avoid that product its typical junk so i went with this one and it was a good call it warks and i maed a cheap blasting cabinet out of a clear storage tote, toilet bowl flange, neoprene dish glove and drilled a hole for the nozzle to poke through the side. I use my left hand to hold the part inside the tote and right to hold the blasting gun on the outside. I also cut a hole in the lid and used a wide mouth tea bottle with a few scotch bright pads cut to fit inside and a hole in the end for air pressure to escape. the only issue is the lid need foam sealing tape and come clips to keep the media in. Coast me about $20 to make.

Works for hobby jobs

Great product for the price. Not a professional piece of equipment but great for small jobs.

Clogs with coarse media.

Exelent

I was able to hook a water separator and hose to the inlet of the included regulator, but air leakage made it unusable; it leaked copiously from the regulator top to gun as well as where the metal adapter threaded into the gun. As others have mentioned you cannot attach a normal air fitting directly to the adapter in the gun. The top connector on the regulator uses a flare fitting but the double-sided male adapter in the gun is so poorly machined that you cannot get it to seal. The threads on the adapter are poorly cut, looking more like Acme threads, while the nut on the regulator top connection (the flare) look decently cut; they do not like being screwed together. The adapter has a vague depression that might have been intended to receive the flare on the regulator but it is off center, irregular, and has a partial groove that lets the air escape. The other end of the adapter screws into the gun; threads directly into the plastic. it appears to be pipe thread but doesn't quite match 1/4 NPT; I tried threading in a brass male-male 1/4NPT into the gun and it tightened up way too quickly and I didn't want to risk stripping the plastic threads. So I doubt I can just get a fitting at the hardware store but will try. If I can find one and if the air leaks can be minimized then I may raise the rating for this blaster. The only good thing is that even with all the air leakage, I did briefly try using it for soda-blasting a carburetor body and a painted plastic surface and it actually worked to clean those surfaces. So hopefully it can be made to work despite the terrible machining. Added 8/13/2024 - I found the part needed to replace the terrible adapter. Tru-Flate 21-595 Ball End Adapter, 1/4" MNPT - 1/4" MNPS. It is a brass part and, while also made in china, is properly threaded and has a properly machined flare to match the one on the regulator. Using pipe sealant on the NPT male end that threads into the plastic gun, there's no detectable leakage on the output side of the regulator. The input side till hisses despite having teflon tape on the NPT threads there (also poorly machined on the regulator) but not enough to cause problems. A brief soda blasting test worked better than the previously, mostly due to more available air pressure.

Unlike most of this type sand blaster, you can get replacement tips for it. I bought a pack of two. I haven’t had the opportunity do use one of the Replacement tips yet because after 150 pounds of sand it is still going strong with the first nozzle. I’ve only used medium and fine grit and I haven’t had any clogging issues :-). All in all a pretty good detail sander to get those smaller spots or get into the really tight areas on a bigger job. I’ve also used it in restoring a couple old tools that were rusted solid. That worked very well. Restoration efforts may be the best niche for this kind of sand blaster.

Works as described. I recommend Teflon tape on air inlet threads as they leaked air.

after a couple of failed attempts with suction feed guns this unit works great highly recomended

The seal at the bottom wasn’t air tight and spins, this means air escape and the pressure can’t be trusted and the compressor runs constantly

Han funcionado muy bien para cortar cartón que es para lo que las pedí, no las he utilizado para cortar otro material, llegaron en tiempo y forma. Ayuda mucho para no utilizar tijeras comunes ya que se dañan al cortar material grueso, dura bien la batería

Great

First off; I have never used a sand blaster before. I bought this to clean carbon and stains off the exterior of aluminum small engine cylinders. I bought a box of #10 (very fine) glass beads to try with this blaster. I have a 25 gallon compressor and it had no problem supplying enough air for this small task. I must say, this blaster and the #10 glass beads worked excellent. It didn't damage the cylinder, but cleaned it very quickly to like-new condition. And I only used about 1/2 of the hopper to do 1 cylinder. The blaster itself was easy to assemble. The regulator attached with no issues, and I attached a standard air fitting using some teflon tape to the regulator - also with no issues. I found I only needed to turn the hopper valve on half way to supply enough blast media to do the job. I also found that the fine glass beads with drain out of the hopper just by gravity if the hopper valve is fully opened. As for PPE - I wore an N95 mask, safety glasses and a full face shield. That seemed to be adequate for the job I was doing. I did the blasting in the front lawn as I didn't want that fine blast media anywhere near the house. I used so little that there was no trace of it on the lawn when I was finished. For my purposes, this blaster gun is excellent and I highly recommend it for occasional cleaning of small parts.
