Recently got a harbour freight / princess auto sand blasting cabinet on sale. I did the most recommended mods to it before using it, namely sealing the cabinet with silicone and replacing the pickup tube with the bottom mounted metering valve.
The cabinet has a water separator plumbed in, and all of the lines feeding it are 1/2", line pressure is 100psi.
My issue is that it doesn't siphon sand properly, regardless of what I have the metering valve set to. It will blast sand for about a half a second after pulling the trigger, but stops almost immediately. What am I doing wrong?
