Cheap modifications and improvements. Great results. • Here is how to make your own metering valve: • DIY Metering Valve for Sandblasting C... • Metering valve - Take a look at 3:55. All the parts used are there but one, the bushing that holds the T to the bottom door. The metering valve is empty inside, there are no hidden devices. The only mods I did to the plumbing are: 1) I used a file to smooth the female threads in the bushing to ease the flow of the media, 2) The bottom plug is hollow inside, so I used JB Weld to fill it, • 3) As you can see at 3:55 I have made an opening in the big pipe (secure it first to the T to make sure the opening and small pipe will be at the top), threaded it and attached the small pipe at the top. Then I have cut the male thread on one side of the small pipe and I made a thread inside it. Then I have drilled two holes on the side. The bolt that goes into the small pipe opens and closes the holes 0:47 regulating the air intake and amount of the media that flows into the gun. Good luck with your project!
