I was making maybe my 6-7 cast of the fronts piece and the silicone on the mold ripped off on one part. It isn't that big of a deal as the mold had a ton of problems. There were airpockets in the silicone and spots where air was getting trapped. The silicone ultimately failed because it just wasn't thick enough in the spot where it ripped.

I will be redoing it, and making it better.. a very good learning expirence.

I just got done casting the first frontspiece for the Ghost Trap. I am having major issues with airbubbles in the cast, because I forgot that there was a flat spot. The casts are ending up needing major work but I am planning on making 5 Ghost Traps.

Here is a picture of a Ghost trap that is just fitted together.

I couldn't wait for the gallon of resin that I ordered yesterday to arrive before I do a few test casts. I ran to the local Dick Blick Art store and luckily they just started to carry Smooth-On's Smooth Cast 300. I was ready to buy a $50 Smooth-On starter kit just to get the resin. But instead $19 on a pint or two of resin was much better.



I found out with one botched casting that I needed to support the main mold box with walls to prevent them from bowing out. A quick fix with a foam core box... and all the future casts are going to be perfect.

For those wondering.. no.. these are not for sale. Not now.. and not in the kit form.

I just finished casting the cassette and the top in silicone. Man.. did it take a long time, and a LOT of silicone. I think I ended up using about half a gallon to do the two items. It wasn't that bad, it just look a lot of mixing and pouring of different bottles of silicone. I really should get a gallon sized containers.

I made up forms from foam core board, and secured them to the bases. The boxes work really well for the silicone and they are really easy to rip apart later to get the mold out. I painted the parts a bright green as I feel it makes it really easy to find imperfections on the surface of the parts, and goes on really thick to make everything smooth.



The green smudges inside the cassette are from my fingers and wet paint.

This is what I have been calling the "fronts piece" ala Arrested Development. It was made to be castable from the start, and hallow at the same time with a passage for electrical wires into the cassette. I am really happy with how this turned out and can't wait to attempt to cast it... it will be a chore!
