Hi everyone – stumbled across this site and I have found it really useful so far so thank you to everyone for all that.
I have a couple of questions. Up to now I have simply been doing my resin castings without a pressure pot or vacuum chamber, I’ve found the stuff is fine around 80% of the time which works fine for the amount of stuff I make as I can easily just do another if a cast fails – I’ve not had any major deadline to run to as it is largely personal use.
However I was wondering if I should look into getting a pressure chamber and vacuum chamber anyway or if the consensus was not to bother until the time issue becomes important? I would say over the last year I’ve probably wasted less in resin costs than the cost of either one of these pieces of equipment.
Other than improving the chances of a successful cast does a pressure pot/vacuum chamber have any other advantage? Does it cause less shrinkage or make for better quality resin?
I’ve read that a lot of people have made a pressure pot into a vacuum chamber too, how hard is this to do. Can anyone recommend a good pot for me to do this with (in the UK)
Also, I’ve been using a 2 part resin from sylmasta which I’ve found to be rather good, but does anyone have a better recommendation of a good quality one? I need something quite strong but also able to hold detail well – casting time again is not an issue to me, I’d rather have something solid that takes an hour to set than something ok that takes 10 minutes.
And I guess finally, does anyone in the UK have an old pot/chamber combo that they want to sell on?
