Thread: Casting Scales from Silver Gold Brass etc.

I guess I forgot to mention the part where you melt the wax out of the investment THEN pour in the silver. Like I said initially, I will be learning the process from someone who has done it many many times. I don't expect there to be any problems.

You might want to take a look at some of the work that John aka Shutterbug has done with metal scales, it might give you some ideas

I know one of the biggest issues he had to overcome was balance.

The pictures finally came through! Please forgive me that these are not scales but one of my favorites.



I got a fossil of a Trilobite which died many times in a bent position. I made a rubber mold that I can't find but you can see the remnants of the rubber. I cast 5 pieces one is the shiny one. There are 3 left on the sprue. The sprue and three weigh 78 grams and the one weighs 11.4. The sprue isn't wasted because you can remelt it but you need much more metal than your finished product.

Casting is so much fun, I'm gonna start this summer again with silver and gold if all goes well.
If you start casting on a larger scale this machine is a blast; Buy yasui digital wax injector aacii - Business Opportunities
And an induction melter is always nice, since it melts the metal so fast it's less chance of it developing the strange "hydrogen sickness".

I have a friend that used that machine for the casting of pewter "Renaissance Faire" objects. Not cheap but it does work fantastically well! Specialized rubber compound is needed for higher temperature metals casting.

Is that one of those setups that looks like a record player. That would be an interesting way to make scales.

Hmm, now I'm confused!
He used the wax injector for pewter?
No, I must be getting it all wrong....

I use either Castaldo rubber or different silicones to make molds, the silicon ones can take a lot of heat.
No problem casting pewter/lead/tin in those.

A great thread,Only casting I have ever done was using cerro-bend to mold rifle chambers,looking foreward to more info

Just for inspection of wear or to get measurement to make a new bolt?

New barrels to measure the throats for more honing.
