Hello. I'm thinking of making a keychain, so the material has to stand up to some forces and scratching. I'd like 2 colors. One is a flat shape with holes, and...
Yes, I'd like to use plastics or something - not metal - for my keychain. I'd like to add color to the substance. What holds up to the forces a keychain...
Good Morning, Attached is a flyer for our new 1941-47 Ford COE trucks. These are available for immediate delivery. If anyone needs a colour copy of the flyer...
Hi John, I sent this out to my dealers and I thought I had taken the mailing groups off the list but apparently not. The attachment was stripped by Yahoo ...

Hi all, A molding provider that I found and "contracted" through this group is refusing to respond to my inquiries. I have little doubt that he COULD provide...
I hope I'm using the correct terminology here! I'm trying to cast some 1/72 scale model parts. Connecting the part and the pour block is a sprue made from 0.3...
Hey Rob; Sorry in advance for the dumb question(s), but I need a little clarification...... #1 you state that you are using vacuum; are you pressure-casting as...
Hi Ray, Thanks for the reply! The answers to your questions: - no, I don't use pressure, I don't have the equipment - yes, I place the mold with resin in the...
You just may be creating (promoting) that bubble by vacuuming Rob.....just a thought. But, on another note, I too have utilized OLD resin (a year or so old),...
Hi Ray, I need the vacuum to fill the mold cavities, so I can't do without. Your warning against using old resin is noted! I wasn't planning to cast 'real'...
I had pieces ooze on me once, I called smooth on and they said it was because I didn't mix part A and B before combining them. Now I always do this and I...
You might also want to consider using a "squeeze molding" technique. If I understood your picture yesterday your cavities each have a vertical rectangular fill...
Ted, thanks for the idea! Unfortunately it probably won't work with my mold. I (deliberately) used a very soft silicone rubber, 10 Shore. It means I have to be...
Rob, Another thought. If you put a simple frame made of wood, plexiglas or such to hold the outside shape of the mold the plugs won't slip past. If the soft...
Hi. I'm new to sculpture and have never casted anything before. I have a project I've done in clay and I wasn't exactly precise about getting the air bubbles...
Right off the bat, do you have access to a kiln? If so, does it have a good kiln sitter? If both are yes I would suggest a slow ramp up to 190-200 degree...
Hey guys, I've been casting with resins so I haven't played around much with plasters and now I'm having a proble, I hope you guys can help me with. I bought a...
James, I have worked with Industrial White Hydrocal and Hydrocal 1A and 1B. I always add water to the Hydrocal until it is a fairly thick consistency. ...
I'm a sculptor. I learned the procedures the bookless way in art school. No reading of instructions. We were taught to put some warm water in the bowl and...
I use that same method at work, and I mix up a lot of molds. But, I believe the ratios you mention, James, are for volume, not weight. Tony Burgess Tulsa, OK ...
... Per U.S. Gypsum: "STATUARY HYDROCAL is a basic HYDROCAL cement with a lower use consistency of about 40 lbs. of water per 100 lbs. of plaster. Extremely...
James, It seems that both Tony and I were mistaken about mixing by volume. According to the LINK that Malcolm sent the ratios are by weight or mass. The ...
Oh my :-) So may options. Option 1) A plaster slip mould would be cool. Option 2) A latex mould backed up with a plaster mother mould would work. Option 3) A...
I believe you should be measuring volume rather than weight. I was always taught to sift hydrocal into the water until it sank and wet itself. when it wouldn't...
I have been having trouble. I have machined some molds out of HDPE, they are 2 pc molds. I am using Alumilite white trying to cast my parts. I am having...
