Pressure pots

Ladies and gentlemen
I have come to the realisation that I need to go next level when making pen blanks etc and have decided I need a pressure pot.

Is it as simple as going to super cheap auto, grabbing a pressure pot, but my blankls into it, flash up the compressor, pressure the pot, wait till it sets and Bobs your Uncle?
Thanks
Willy
PS, Please keep replies simple, I am getting old and couldn't be bothered reading long wing winded, verbose replies (hope that doesn't sound arrogant?)

You will need to modify a couple of fittings on it. They are set up to pressurise and spray paint - there is a tube going down into the centre of the pot that you will need to remove. You may also find that the pressure relief valve that comes with some pots releases at too low a pressure (I like mine to release at ~ 65psi and I usually operate the pot at a regulated 60psi). I have a pressure regulator on top of my pot, plus another at the compressor on the line supplying the pot - both are set at ~ 65psi.

Not sure what comes standard on the ones from Supercheap Auto - I bought mine from eBay and modified the fittings etc to suit what I needed. If you do replace any of the air fittings on top of the pot - don't use thread tape when assembling it all - guaranteed the fittings will leak. Go to a decent hydraulic hose shop (ENZED or similar) and get some good quality thread paste from them and use that on your fittings.

For making pen blanks etc - make yourself up a "rack" that fits inside the pot so that you can stack multiple layers of molds inside the pot. My first effort (shown in the photo below) was made from plywood, dowel and a couple of drawer handles. I have since made a better one using plexiglass sheeting (thinner than the plywood and easier to clean - can fit more in it). I have also recessed my pot down in the bench top - makes it easier to work with - but I have a bench that is dedicated to vacuum and pressure casting etc.

Good Afternoon Ladies and Gentlemen

Well, as I recieved some good advice here, I had planned to sally forth and purchase a pot. Alas, a friend of mine said he had one, it was given to him, now I have loaned it from him. Winning!

Anyhoo, I have modified IAW advice recieved here and will do some resin work in the near future, pics will be supplied
Cheers
