HF Sandblaster Metering Valve Build - Part 2

In this episode I finish the last few operations of the DIY metering valve and show the assembly. I also carry out some tests which show some improvement over the standard pickup tube supplied with the blast cabinet. If you want to go straight to the testing, go to 15:40 Still, it's not a total solution and I have started on a new blast gun design which might give me a continuous supply of media to the part.
