Homemade Pressure Sandblaster




What do you think about this video?

grey punk: seems like you're in PAIN dude lols´╗┐

Jebus: lol ... the power point presentation via youtube. Stay classy!

german diaz: buenisimo gracias

yatebulo: can be done with water instead of sand also ....

Roberto Berti: This is one of the few videos about Homemade sandblasters, but can we watch how it works? I would like to see it. Thanks.

ShortyzProductionz: ok thanks. i already made one and figured out why haha

thinkpad411: It won't fall into the hose because of physics, there would be source pressure pushing back into the pressure pot, keeping the sand from "falling" into the hose, and there is no venturi effect in the mixing chamber that is the tee. The pressure is to inject sand into the outgoing air stream with force. You can however make a hybrid siphon feed system, then you would have vacuum at the gun mixing port, and a light pressure of 10-30PSI would be enough to keep the sand flowing, not better, safer.

rudy sanchez: thank you for thevideo, I want to know how many PSI need this project to do a work, beacuse I got a 100 psi compressor, so I want to know if I need to do somting else

Jenny julioan: i work for a firm that does this and have been doing it for 7 months now. i am learning a lot from this video

heiken01: here are some plans for free: vintageprojects . com/metal-welding/SandBlaster-plans.pdf :P

oneyaker: @Dln4936 Most pressure vessels are welded. No one cares about certification on trash propane tank. You fill it with 100% water and pressurize 200% expected pressure to test and if it holds you are all set. Water filled vessels will rupture and squirt but not explode. That is how pressure vessels are tested.

6evorev6: @Dln4936 True but the safety release valve should kick in before that.

ShortyzProductionz: Ok again I'm still confused but wanna know how to make one... Ok so what's the point of the air going into the tank that holds the sand? Won't gravity make the sand fall into the hose to get shot out?

HRVAT1975: @shortyjk95 lol...

shortyjk95: Didn't help at all Learn how to speak cuz I confused

jitskid831: Cool thanks for the info.

arnoldcustom: any one that knows anything about presser and media flow will know as soon as they look at the fittings on the mixing valve what needs to be done for it to work wight, it is very clear in then cheep Princes auto presser sand blasters that the mixing valve is going to clog up all th time, simple as changing fitttings and air hose size, flow of anything can not flow well using 90 dagreee fitting, use a few 45 degree fitting in the direction of flow to start off with

HITCHHIKERNAIEM: nice video .. keep up the good work ,,
