The Resin Casting Kit came in today and I was able to make a pretty good copy of my first pylon. I've got a finished picture here for the impatient... The process begins below.
First I had to glue the plyon down to something. A lid from a popcorn tin came in handy.
Here's the Alumilite 1lb Super Casting Kit.
I really should have made the form smaller, but you can see it is sealed up with the clay that was provided.
The silicone bubbled a bit ominously, but there was not a strong or unpleasant odor. Since my form was so inefficient, it used almost all of the silicone. :-(
About 10 hours later it was cured and ready to go. Sadly the baked clay broke during removal. I really should have waited another 8 hours to be sure but I was very impatient.
Here you can clearly see my imperfect sculpting of the grooves. Not something I'm worried about, but I might consider fixing if I was going to sell a bunch of sets.
Ready to mix, the powder is baby powder used to line the mold prior to pouring. You have about a minute and a half to mix and pour, so no pictures of the mixed up solution.
Crap... After all of my careful displacement tests I still made too much resin. There was 1/4 ounce still left in the cup too.
12 Copies completed. Unfortunately around number 11 the resin failed to fill completedly and left a piece in the mold. I was able to retrieve the piece but damaged the mold in the progress. This makes me sad, since I had high hopes for being able to cast another set or two of these.
I blame this on the fact that the mold was so thick at the top and it was very difficult to remove the pieces, or bend it to ensure the resin flowed in well. But, look how much resin I have left! I may have only used about 1/4 to a 1/3 of the resin that came with the kit.
