Would this pressure pot be a good buy/ good starting pot?

[TheMasterTurtle]

Hi All,

New here and trying to seriously become a good molder/ caster. I have done both in the past however never with equipment. Im now looking to change that...

I have a craftsman compressor so now all I need is the pressure pot. Is the following a good buy? would it work for what we use it for? I would rather start with a used model to spend less money if I'm a complete failure. At least that way the financial blow wont be as large.

thanks all

it really depends on what you'll be casting. definitely a good buy it you're doing multiple or big molds as it is a 5 gallon. definitely not ideal for small stuff as you'll be wasting some time driving air into it. with that said, definite good deal due to the size. also, a lot of those fittings you'd probably want to change out and plug as they look cumbersome for casting. as it's on craigslist, definitely haggle if you can.

another route you might want to go with is the harbor freight 2.5 gallon as they aren't too expensive and can handle the pressures for simple casting. just remember that the rubber seals they come with aren't ideal for a tight fit. what i do is is pour the same silicone i use for casting into the groove. some people use simple bathroom silicone which works as well.

hope this helps!

For a 5 gallon pot, that's a really good price.

It looks nice and clean, too. If it's that clean on the outside, he probably has it pretty clean on the inside as well, especially if he used liners. If you're serious about pressure casting, like relikizan said, it's a good deal.

Thank you both - its all helpful. As far as fittings go, are there any tutorials or information of building one/ maintaining one? Pressure pots are SO foreign to me it makes me nervous to buy this thing and either not fully know how to work it, maintain it, or know what parts are necessary and what aren't. He wont wiggle on the price but if you already said its a good deal - well then it is.

Here are his responses. I need to do some very detailed reading about Pressure Pots to understand the other language he is speaking! I assume everything below makes sense to you both and it's nothing major especially because he says he will be picking a new tube up.

"It operates well. The pickup tube is missing. Along with the pickup tube a wing that attaches to the pickup tube is also missing. The wing directs the liquid from the agitator to prevent swirling of the paint. The pressure pot holds liquid that would be sprayed out thru a paint gun. It is used to spray heavier liquids"

"I will make a new pickup tube for it this week. It's actually a pretty simple part...just tube with a pipe thread screwed into a fitting on the head. My painter friend said the baffle thing that is missing is not that important but it will not work without the pickup tube. Thanks for looking."

So I think if theres any chance of my getting serious I need to get the right tools and equipment to make it happen. This would be the first step I guess.

To use this pot for casting, you'd be removing the pickup tube anyway-- the fact that it is missing just means you're a bit further along in the conversion to a casting pot. Now, if the missing tube means that there is a hole in the lid, you'll have to determine a way to plug up that hole. If it's a threaded hole, you can probably find a pipe plug to match it.

Here's a pic of a plug in the pickup tube bung on one of my pot lids:

Oh that's great news then. I hope to pick this up and SUCCESSFULLY convert it. The specifics make me nervous. I was given this link to help in a conversation
