Italian Job Gold Bar Project
Thanks, I'm hoping to do a v2 later that is more 100% replica rather than a direct casting. Due to material shrinkage the end product currently is a bit smaller than the screen used prop. Will take what I learn from this early bits and work to get a more accurate replica down the lineThis is such a cool project! Great progress so far! Can't wait to see how this all turns out!
And how big is it exactly?
Bit of a personal question don't ya think.And how big is it exactly?
The original is 9.5" long. After the resin blank and the metal casting, its about 9 3/16"
So I went ahead and created a two part mold using high temperature silicone (mold max 60)
Also got myself hopefully enough metal in these ingots to get 2 solid bars out of.
I have 1 4-bar stack of Pure Tin and 1 4-bar stack of lead free pewter.
I'll do the tin first since it has the lower melting point and then see how well the pewter does. Will also try preheating the mold in the oven so the temp difference when the metal goes in isn't chaotic enough to cause artifacting in the finished cast.

First bar from the high temp silicone mold is out. This was done using pure tin. I got better results and the size is more accurate to the original prop, but I'm having issues with surface air bubbles. I'm thinking this was due do issues with the heat and air/moisture still in the mold. Next time around I will preheat the mold and hope for better results
