HI we vulcanise at 25t usually, we use metal hollow nuts with hexagonal surfaces. we always put a ring of them around the outside but then have two or three...
... You vulcanise at 25 tons? Is that a typo? That would be about 50,000lbs (1 ton = 2000lbs) The dial on my 50ton jack only goes up to 8000lbs. What size...

OK, you're 50 ton jack's dial only goes to 8000 lbs for a reason. The dial shows the hydraulic pressure in the pump unit, NOT the pressure as applied to the...
Hi All, I just made my first RTV mould and cast it with polyurethane resin. While I was happy with the result I now realise the need to cast under pressure or...
Hi Rick Thanks for the info If you run ZoneAlarm, you might not have seen the image. ZoneAlarm blocks lots of images on sites – it is a known bug with their...
Hi guys, I'm curious about the homemade resin spincaster photographed on the main page. I can't find the message thread talking about it (if there is any), or...
Sorry my bad english because I speak french. I create with styrofoam and clay a turtle stepping stone I mold with moldbuilder. The mold is not strong, I would...
Hi! I go by Natario, and I have been involved in sculpting as a hobby for a few years, and have been practicing mold making using silicon for pewter casting. I...
Hello, have you ever tried the alta vista bablefish program? it is a fast translation program. I dont know the answer to your casting question. Bonjour,...
There are a few tricks to making good latex molds for casting concrete. 1. when you make the mold, it should have a good 'flange' (a flat area around the mold...
Lizard, Je suis désolé. Mon Français est très mauvais. Vous employez le latex. La solution est d'employer des composés de bâti de polyuréthane. Créez ...
I looked at the photos. I think the mold needs to be thicker, have a flange around the edge and a mother mold (see my other email). I made the latex molds for...
Hi All - I was told by Tekcast that when spincasting resins the gate-ing and venting system has to be different to the systems used by pewter alloys. It would...
Polycarbonate is hygroscopic; it absorbs water. In order to vacuum form it you need to first slowly raise the temperature of the sheet above the boiling point...
OK, those are the kind I meant. The acorn nuts are just placed on the top of the lowwer half sheet of slicinoce. It's juat a big disk, usually 1/2" thick, and...
True. Actually I haven't vented to the edge for zinc casting, since it's so easy to vent through the disk to the top or bottom of the mold, letting the air go...
There was a discussion here about using silicone oil and heat to renew silicone RTV molds for longer use. The other thing is that if you use a barrier coat of...
Brad, I once asked the very same questions as you, so I hope I can help with answers now. You can re-use old RTV molds by chopping them up and suspending them...
A few answers interspersed below....... On Mon, 2 May 2005 10:03:56 +1000 "Brad May" <may_brad@...> ... Probably not a good idea. Even though the cut...
... Hey Ray, That's odd. I don't know what's up with that. Did you try going to the home page first? http://www.earthly-creations.com/ I don't have any trouble...
A block mold, as Marc suggests, will also certainly work, and work well. We used PMC 121-30 and PMC 121-50 (also Smooth-On products) for some of our concrete...
