I just got a nice Graco delta spray gun at an auction, however, it didn’t come with a pressure pot. New ones are pretty expensive, and I don’t want to invest a lot in finishing equipment right now as I won’t be doing a lot of spraying, and I would rather put some money into a nice compressor.
I have metal working experience and a machine shop available, and so fabricating something wouldn’t be too difficult. I’m thinking of a pot with a removable liner and a quick release top on it. For my needs it wouldn’t need to be larger than 1 gallon. Then the only thing left is the fluid and pressure regulators which I would have to buy (the expensive part) as well as hoses. I’m hoping I will be able to build all this for around $100.
Has anyone built something like this, or am I crazy. The pressure pots i’ve used haven’t required high pressure, so I don’t think I have to worry about the thing blowing up. Do you think it’s worth the trouble or am I better off just buying one? Any other comments are also welcome
thanks

Andrew,
My first pot was about a hundred bucks from sears. The gasket was junk but easily replaced with one fabricated from a sheet of rubber. The lid clamps left a lot to be desired in their action also, but for the size and money of the pot, I'd say it was a good deal.

I've been spraying for years with a hundred dollar 2 gal pot from sears and a cheepy gun. The gun cost about fifty dollars and came with a detail gun thrown in. I went to Napa and got one of those yellow corkscrew hoses and hooked it up to carry the lacq. and hooked up a regular hose( should be a nice soft one) for the air.
I fixed it so the air hose runs through the squirly que hose for the finish and tada there ya go.
I always wanted to have a pot for sealer and a pot for the finish coat and this year sears put the 2 gal pots on sale for a hundred bux and so I sprung for anothe rig. Went back to napa for another yeller hose and went to Wally World and got a gun for $60 and used a piece of hose I had around the shop for the air. I put quick connectors on the air, but don't think they would like the finish in them so I just used regular fittins for the juice.
What I do is to put a gallon can in the pot and go to spraying. If I want to spray something else I just have to take one can out and put in another. Before I got the other one I had to do that between sealer and finish. You can blow the finish back down the hose into the can before you take it apart.
I also blow it back before I quit at nite, and I have left it for weeks with no problems, as long as I don't leave the air presure on pushing stuf back up the hose. The vapors seem to keep the gun from gumming up.
The cheepy gun seems to spray just fine. I really haven't ever used a real good gun but I can't see how it could be that much better than the job I have been getting for all these years.
Oh yea, the guns I use came with quart pots attatched to them, but when I took them off I was able to attatch the hoses up to them like they were meant to be used that way.
Here I'll show you a couple of pictures of the set-up. I use to not have the springy hose but decided to try it when the old straight hose gave out. I don't think I will go back. I have both units set up that way.
I'm not saying a nice binks wouldn't be nice but the old ones just keep on going and going so I don't know if I'll ever get one.
I don't know about you but I like reinventing the wheel, but if you are gonna spend 100 bux and several days work to come up with a spray pot, you might try just buying one from old sears. A pot is a pot , and both of mine came with the regulators attatched. I think you can even get them from Harbor freight for pretty few bux.
