Having some parts cast.

This is very interesting, please detail the process. I am familiar with the traditional jewelry lost wax with the wax formed freehand.

As I understand it he will make a mold of the part with silicone, then he pumps the wax into the silicone. Somewhere in the process he will put a graphite rod in the places where a hole would be, like the hole in the primer cup. He can drill the graphite out after they’re cast. This is how he does the hollow stems in the lamps his lamps get a wire in them and they actually light up. The centifugal foundry is neat. It winds up like a watch and when the metal goes in he releases it and the metal is forced into all the nooks. I’m missing some steps I’m sure but that’s the jest of it.

Here is a tiny cowboy riding a horse he cast. The details are incredible. That’s a toothpick next to it.

That's pretty incredible. Lots of detail. Wonder how much time he had in making a mold for the tiny cowboy/horse? I bet you parts turn out like new.

It was my understanding he did the horse and cowboy in a day. The pictures don’t do it any justice.

that is amazing work being able to cast those small parts with such detail what a rewarding effort thanks for the update

Phenomenal work. You realize you are not going to be able to use any parts he casts for you. You are going to end up selling them as art work.....

Keep a set for display purposes when you are done.

Just got these pictures of the wax molds. Looks good to me!!

Fingers crossed

Hi Pete, your questions are the very first thing I asked Jim when we talked about the primer cups. Jim says they will shrink a bit, but both parts will shrink at the same rate so they’ll come out close???????

I had wanted him to leave the tapered hole out so I could bore it with a tapered reamer. Jim looked it up and down and said “ I think we can just cast it in “. So I’m as antsy as I can be to see how they come out. All I know about casting is what I’ve watched on How It’s Made so I’m relying on Jim.

Of course the primer cups could be a fantastic failure, if so we’ll melt em and try again.

Now the other pieces I’m not concerned a bit, if they need a hole reamed a bit then so be it.



He is pouring Thursday so stay tuned
