Somebody knows... Maybe you?
By the way... I would love to come over and take a look at it.... but the drive is just a bit too far and I think I might get wet in the process!
That looks like some great stuff!Gameswat wrote:Gamblingman, sounds like you might need to invest in some of this product or the like, [xurl=http://amazingmoldputty.com/ProdDetail.cfm?Category=Silicone%20Rubber&Name=Amazing%20Mold%20Putty]Click here for link[/xurl]

Edited to add external link BP
I've had huge success with it copying some very important parts as no shrinkage in the mold. And especially when I was just visiting fellow collectors with similiar machines, I could quickly mold this stuff together (1 min) and form it over the part while still in situ on the machine (3 mins). Wait about 10 mins and then off comes a superb silicon rubber mold to use later. And not even any mold release needed unless it's a very fragile surface, then I cover with something like clingwrap first. You could prob even send some to an owner of a Jewel Box and ask them to mold it for you. Good luck.
I've been thinking about this stuff Amazing Mold Putty that you introduced to us.
I note it only takes heat up to about 200 C.
What do you use to cast the item in? I can't find anything that melts at low enough a temperature.
BP, I've only cold poured using these molds, usually to make resin or plaster patterns for my foundry to sand cast from. Preferably something that doesn't shrink much, though I always oversize the patterns by 7% to 10% with car filler putty or card glued on the edges to account for the metal casting shrinkage anyway. Can't tell you how many rare and valuable early machines I've seen in the states with sloppy fitting cashbox doors and trims etc! I've also re-made automaton heads straight from this silicon molding putty too.
Since you brought it up.....I am getting ready to send the buckley door pattern I made off to be casted. The guy at the foundary told me 3/16" shrinkage for every foot of material. Since this door is a little over 5 inches, I left a generous 1/8" on the inside lip all the way around.....but what you are implying is that the shrinkage is much more. You would be talking at least 3/4" per foot.....is that what you have been experiencing? Just curious as this is the first project I have sent to be casted.....It took a lot of hours, but I managed to make a dead ringer for that Jewel Box door, and I don't want it to come back unworkable.
