Caswell Gun convertion

Re: Caswell Gun convertion

Does one hose supply air to the container, and the other return a supply of pressurized powder in return?

Yes that's how it works. I need to add a bleeder fitting and line to stop the pressure build up in the container.

Tonyklem,
I will check what size fittings I used. It is Steel Brake line coming out of the gun. The fittings, I forced fitted it into the plastic, as there were no threads. It now has threads, compliments of the fittings. The container I drilled holes for the fittings that I got from Hardware store and epoxied them in place.

Hey I rigged something similar up over the last weekend. It helps A LOT to use a small tube (for the air supply into the powder) and have it reach just about to the bottom of the container. Then drill or punch several little holes around the bottom inch or so of the tube. This really helps to fluidize the powder with less air.

Only ever seen Conduit Locknuts in 1/2" pipe size the smallest.

Re: Caswell Gun convertion

Can I make a suggestion? Instead of using epoxy on the fittings, why not use the thin nuts for securing electrical fittings and pipes to junction boxes? I used similar hose fittings on a test hopper cap and they stayed nice and tight with them....just a thought!

Didn't want to intrude on Beebob's Hopper thread so here is the Caswell Gun conversion to a hopper. First off let me say that It worked fair, but the biggest problem is the CC jug that I used. With the amount of air it takes to make the powder flow, it would swell the jug up and blow powder out around the lids threads. So, that will have to be addressed with a different heavier duty jug with a seal for the lid.

Here is a link to a thread with a couple of other idea's.

Can you give some details on how you modified the gun itself and what parts you used for the fittings/lines on the gun?
