[Cool Hand Lurker]

I have never used a siphon gun sand blaster that didn’t have a problem plugging up. The sand tends to pack up in the siphon tube. The vibrator that MikeK speaks about in the post above is a very good idea. Another alternative is having a hopper that is about as high as the gun will be, with a “T” fitting on the bottom so the sand drops into the siphon air stream.

If you haven’t already built your cabinet I can suggest using a vinyl shower stall. You can get them used or new, just keep your eyes open. The site “doitbest.com” has one for $125. The advantages of using an old shower are many. Cheap, good height, large door, good light. If you simply hang a 4’ fluorescent shop light on the outside it will really light up the inside. You can put an old wheel hub from the rear of a front wheel drive car in the base, put a platform on top of it, then use it as a rotating table. The door is not really needed, just a shower curtain on the lower half and a piece of plexiglas on the upper half so you can see through. Put in a couple of hand holes in the front and an exhaust fan on the top where there is already a hole for the light.

They work well for a small paint booth too. Oh yeah, don’t hook up the water!
