Hi, I hope somebody as some advise on the following. I am about to make a 2 part mold using Hydracal. The piece I want to duplicate in the mold is made of a...

Hi All... Im usually just a reader, but this time I have a small discovery to share. I seen one of those late nite infomercials for the Pump & SEal food saver....
Dave, While everyone including me wants a cheap vaccum chamber, I think maybe you'd better be careful with this one. When used as designed, this pickle jar is...
I doubt that little pump would even pull 10" of mercury anyway. Besides, they don't know if you're going to vacuum -1- teeny Gerkin or a jar full. In this day...
Craig, that's nonsense. If he has the same pressure, and if the pressure (in height water) is significantly lower (higher) than the height of the jar the...
... Answer: Put mold release{3-4 coats} on areas that come in contact with the resin. If it can't stick, it can be removed easily{Fingers}. Just don't let it...
I have a couple of plaster molds, I am planning to make wax castings from them. What is the best way to keep the wax from permiating the surface of the mold...

I think Craig was talking about the liquid inside the jar while under normal pickle holding use, not liquid outside the jar while de-airing RTV under pressure....
Is anyone aware of a 2-part castable polyurethane formulation that would allow cast parts to subsequently be thermally bonded to other TPU's (namely, TPU...
Hello All. As a newbie to casting, I would like to know if any of you out there have tutorials for beginers. I'd be casting things in 1/350 scale for my...
<< Craig, that's nonsense. >> Well, good morning to you too. I mis-spoke myself. I didn't mean to say the water presses back, frankly I had a brain cramp of...
No, this isn't likely, if at all possible. Casting urethanes can't be heated to bond to anything. If you get themm hot enough they may change shape to conform ...
I don't know if I am late in this conversation, but I converted a fairly large pressure cooker (cost $5 at a flea market) into a vacuum chamber. I've pulled...
... Ok, i can agree on this. (I do not fully agree on ... because the stress is (almost) the same. BUT this are only details) If there is less free room inside...
... frankly I had a brain cramp of some sort. What I meant, and I hope I'm more clear in this case, is that the water is not compressible nor will it expand...
I'd still be careful, designing for pressure is not the same as designing for vacuum. Anyone know the "normal" pressure inside a pressure cooker? Alien Steve ...
Hi Pressure cookers as vacuum chambers work quite nicely, have been using this for a long time. As pressure pots, FORGET IT ! The normal working pressures...
Bob, That's a really neat idea for a home-brew solution. Any chance I could get a picture of it? I checked on your website, but couldn't find any. What...
