View Full Version : Waste molding and resin casting photos

01-08-2015, 02:21 PM
Just a short note to mention that I'm posting waste molding progress photos on my Facebook page. I'm following the notes and photos Kitty Cantrell sent to me last year and so far everything is going very well. Thank you again Kitty!

After I get all my progress photos together including the resin casting part, I'll put the photos into one PDF file and add that on my website. Right now I'm working on one mold following Kitty's instructions and one small block mold using legos. I'm also going to try and create the production molds for these two pieces. I'll share the progress photos for that also. I'm new to this but I'm hoping everything will keep going smoothly.

Thank you immensely for posting this Kimberly! And of course thank Kitty for me (and others) for that fascinating tutorial!

May I ask what the wires across the top are for? I thought I'd figure it out after reviewing this a few times but I just didn't.

Otherwise this looks like a great alternative to the way I learned to do shell molds. Almost as little rubber but a great deal less risk! I'm very excited about this!

You're welcome ;D
The wires on top.. from putting the mold together I think it helps the roof of the mold not cave in when securing the clay on but the wires sticking out also gives the plaster something extra to grab onto . The plaster is runny when first mixed but after 5-10 minutes it gets thicker and easier to put a thick layer of plaster over the clay.

I got to pour the mold rubber tonight in the plaster clay mold
It took 76 oz. of the Mold Star 30 that I mixed up. So far everything is turning out perfect.

I'll be taking more photos tomorrow to share. I'll get to open up my block mold in the morning and then start taking apart the clay and plaster mold so I can build the outer plaster shell. If all goes well I might have the first resin or two by tomorrow evening. So exciting.

the wires across the top are to keep the top from falling in when the weight of the plaster is put on.
I pull them out after the rubber sets. I am working on a GIANT paint on mold of the lifesize bobcat right now. new kind of silicone w/ a thixotropic additive.
hopefully this will work and I wont have to use cabosil to thicken the rubber. I HATE wearing that big heavy mask!
mold making.....always an adventure. I have a small guest cabin....if ever a few of you want to get together to learn/teach different mold making tecniques,we could do it here. GOOD LUCK Kimberly! don't forget the vent hole on the top of the mold.
