    Welcome to the casting craze I left the feed pipe in mine, and just work around it - you never know when I might need a paint pot for actual painting Mine still loses a little air, as there's one connection that I can;t put thread tape on due to the design, and it leaks there, but it's not significant enough to stop the process working fine - I haven't hit an air bubble since I started using the pot.

    My big pigment order finally arrived this week, but the darn weekend's almost over and I've only just got into the shed!

    Default The missing seal.

    Here it is, I had recorded my receipt number in Quickbooks, so that is all I needed, the people at SuperCheap were very helpful and opened up another box and took the seal out of that, I told them to sell that one to another pen turner!!, Well i fitted the seal and there it is holding pressure, now comes more organising to get to casting. Thanks Fred for all your help and input, if anyone else needs help I will send them to Sam or Russell or USA but not Fred!!!, seriously, you have gone out of your way to help me, hope I can repay that favour with some excellent blanks. Amos.
    PS, Russell, like you, my weekend is almost over now, but I learnt a lot from yesterday about Quality and aiming for excellence at all times; Yesterday could have been accomplished in one hour, if the fittings sold to me had been the correct ones. All to do with care in producing our goods. Amos

    Re SuperCheap pressure pot. If you want to remove fittings and suction tube under lid easily, just heat with a gas torch to soften the gunk they use to air proof fittings. Sorry if someone has previously mentioned this.

    I have been keeping my eyes peeled for the price at Supercheap to come down again, but this afternoon I believe I scored the bargain of the century.

    I decided to search good old Gumtree and as luck would have it, a pot popped up.

    Being sceptical at first I went for a look, and to my surprise I scored a brand new steel 10+L pot (that I can barely lift) with a pressure rating of 90psi. The pot is brand new and was sitting in the guys workshop for a few years. He decided to get rid of it and I got an absolute steal @ $80

    Now the learning adventure of casting begins

    Normally I am not overly patient, however today I learnt that it does actually pay off some times.

    Happy Days

    The working pressure is the rating to which you pressurise the pot, just make sure the 90psi is not the ultimate pressure before you go that high.

    Thanks for the heads up dai sensei, appreciate it. The decal lists the maximum working pressure at 90 psi.

    So to excuse my ignorance here, would I be correct in thinking I could pressurise to 90psi on the gauge (in theory, I don't think I would ever need that high surely)? Just trying to get it right in my head from the beginning )

    Looks like a good unit. Yes you can pressurise to 90psi if that is the working limit, and I would, the higher the better is best when casting.

    Looking forward to a few pen blanks for a start to get the feel of it, then I think I am going to have a dash at a dragon ball!

    Change of plans. This Star S770 only goes to 30PSI. Dammit - now looking for another pot.

    Okayyyyyy,

    Went to pack up the above pot to return it to my father - behold, this was inscribed on the lid:

    20190211_171844[1].jpg

    The instructions talk about operating at 35PSI - the lid states not exceed 80PSI.

    Safe to use as a pressure pot?? Opinions?

    Tumbleweeds.

    lets see if I get a reply now, I have one of the Supercheap units, trying to figure out what size elbow to put under the lid. Anyone?

    Mine is not a Supercheap unit but I think they are all pretty generic. I assume you are looking at putting the elbow inside so the air doesn't go straight down and displace any of the resin. On my unit the socket in the lid is 1/8" BSP and elbows are not real common in this size (at least not from general hardware anyway). What I did with mine, probably because I had one on hand was use a push-in tube connector and drilled a couple of holes in the hex part for the air to get out. I just cut the thread off a 1/4" or 6mm bolt and pushed the plain part of the shank into the connection.
    On mine the outside part of this socket where the regulator screws in is 1/4" BSP so it actually steps down to the inside fitting. In the first photo you can see the difference between the inlet connection and the outlet/dump connector. The outlet is 1/4" BSP.
