OMG you saved me thousands of dollars I didn't have on a sand carver when all i really need to blast 800 grit is a pressure pot instead of a syphon tube truly explained properly, your work keeps paying dividends!
Hey I just wanted to thank you for your videos. I'm considering building a sandblaster for my shop and your diagrams helped me get the basic design straight in my head. Your time and efforts are appreciated.
first class information Here! wish I had seem them years ago, a pressure pot can be full of gremlins when you need it the most. Thanks for uploading this.
Thanks a lot I'm having problems with water condensation, (I live near the cost so it's rather humid) & I'm sure I know what to do to fix the problem. It seems that it would be safer if the Diaphragm Shut Off Valve would close when no air pressure going to the it, rather than open. That way if the tubing or foot valve broke or something it would shut down the flow of sand. But maybe I'm wrong. Your 2 videos really helped. Thanks again.
all ur videos are really awesome, was looking for diy sandblaster or some info on how it works, most of the vids in yi just confused me, but after watching urs, now... now i think i can make one :D
Very well done, but my question evolves around the air supply. It seems most videos completely ignore perhaps the most important element of blasting and that is the air supply. What would you recommend in terms of compressors--not manufacturers--but specifications. Thanks for the videos.
You need to understand that yourself. You need to calculate it, or estimate it, or try and error. Direct Pressure is at least 15cfm. 15cfm (5hp) was my first built. Was not enough for 1/2 inch hose, so I made the hose and nozzle smaller to keep up.
Mr. Kuhn, Thank you for sharing the information. You have made the entire list of equipment understable and clear. Do you have any suggestions for quality suppliers? Again, Thank you for the lessons.
Hi have mine setup but having problems with the pinch valve not shutting off and the tank wont build up pressure Richway wont reply to my emails and got my pinch valve off aliexpress any ideas would be greatly appreciated
That shut off valve for the foot peddle should been fitted before the media and air are mixed otherwise the valve with get destroyed by the high pressure media flow over time and those valves are expensive....it should have a one way valve fitted just after it also...
what type of valves and hose is typically used in sand blasters, i imagine any valves/hoses downstream of the pot are consumable and take quite a beating also whats a good pressure to start with before dialing it in exact
All blasting cabinets are built by people who don't blast. I have been doing this since 80's. My cabinet has 0 dust, no pedal and no trigger. I sit there, drink coffee or whisky and I blast. Anything else is a misery. This design above is nice, but has flaws. The Diaphragm valve will deal with sand/media and there will be problems fast. The new design uses air valve on top of the cylinder and when you release the pedal it discharges air from the pot to the cabinet. All direct pressure cabinets actually suck, because they are complicated and not much faster overall if you know what you're doing. My suction cabinets are not worse at all. 1/2 inch hose to the gun. Correct media to air mixture at 101 PSI pressure is the sweet spot. All direct pressure cabinets must have "balance". Balance how much air is going through the tank vs the hose. Balance between media type and media valve. Balance between hose size and amount of air, and ETC. I have yet to see someone find that balance in all those machines I watch on youtube. They are all not optimal. In the cabinets I built for direct pressure I had no valves, no consumables. All hoses and nipples were sizes for a specific CFM and media type/size. I did not worry about anything. I simply blasted. The trick he shows you with media getting stuck at the outlet is nice, but unnecessary if you design it all right. You need mixing (bigger area) valve at the bottom, and you need to only send little air through the tank in order to have no more than 33% of media in the final hose. Otherwise it will be a nightmare. There is a trick to stop the media and air from coming out of the gun without any valves, electronics, and etc, but I can't show it or patent it, as people rip off patents right away.

Thank you for these #1 and #2 videos they really helped me!
Thank you for making these video's. Very informative and helpful in setting up my system so it will function properly and with less problems.
Fantastic video. So little out there on non-siphon sandblast cabinets. Just got one used - works amazing!
Well done and useful video. The best out there about this.
¡Gracias por compartir!

Thank you very much for sharing the information about sand blashing.
Thanks for your videos - to the point and intelligent = hard to find such good quality videos :)

This made my whole day I have to tell ya

Très bonne vidéo de conception , BRAVO!
A quel diamètre vous avez percé le petit tube, qui a été mis en suite a l'intérieure de la sableuse.
very interesting and informative. thanks
Can you please tell me where I can get the foot pedal valve? I have found foot pedals, but not the valve. Thanks in advance!

great video thanks

Very well done - thank you!!!
very good
is this pressure pot design identical to that required for wet grit blasting ?
no
Hello friend I am from Venezuela to make one of these as I get started?
Thanks very informative
what type of valves and hose is typically used in sand blasters, i imagine any valves/hoses downstream of the pot are consumable and take quite a beating
also whats a good pressure to start with before dialing it in exact
T
thank you very much
Mr. Kuhn what size hose do you use to make this pot?
Anyone could help me with a wet sand blaster?
Thanks!
Couldn't a clogging problem just as easily be caused by damp grit?
pourriez vous mettre les sous titre en francais ?
