I have tried a lot of different ways to pick up the sand in my cabinet. I always
had trouble with the pressure pots since they are so sensitive to moisture. The
gravity pick up you stick in the sand never seems to be consistent. I have had
the best luck using the setup that comes on the cheap gravity pots. It is just
a simple plastic fitting with an air hole on the top which helps draw the sand.
I ran the hose up, and drilled a hole into the blast area.[IMG][/IMG]

This has been the most consistent, and easiest to clean out for me.
It would be easy to make a fitting like this, the one in the pic is plastic left over
from a cheap Sears gravity pot.
