First Time Casting From My Own Mould

Album image #1
The kits that is missing a part.
Sorry Bob, I didn't know the part was missing from the kit when I sent it to you ?

The resources for this little experiment ?

Bob Esplin suggested I try this reusable plastic. It's very easy to use and relatively inexpensive. However, the instructions and virtual all the writing is in Japanese, so YouTube to the rescue ?

My first mould (or mold). Easy: drop a couple of green plastic bars into hot water; wait a few minutes to soften; mush together into a desired shape; press part into the plastic; wait a few minutes for the green plastic to harden; pry part form green plastic and voila, its done!

My first casting with the Milliput. Not great, but not bad either. I used too much material, so on my second try with the Milliput I will use half as much and tamp it much more as well.

My first casting with the Tamiya. Not great, but not bad either. I used about the right amount material, so for my second attempt I will focus tamping and smooth.

Casting your own part, is very ambitious, what a brilliant idea.

Album info

The part being cast is the lower engine cover panel, which is missing from a fellow Scalemate's copy of the Eduard 1121 Spitfire Mk 22/24. Never having done a mold and casting before, I did some research and took some of Bob Esplin's recommendations. I got some good results for my first try...

I think better results can be achieved with practice to eliminate air pockets, by better tamping of the material, and get a better blend of the epoxy compounds by more kneading and rolling.

The hardest part is actually knowing how much casting material to use. I only did a one-part mould of the outer surface of the part. If I did a two part mold of both sides, I would be hard pressed to judge the right amount of casting material to use, and good results could only be obtained through trial and error, I believe.
