The nut it is to replace is badly worn. He replaced it with a 3D printed nut temporarily, but that's not cutting it, he needs bronze. A threaded insert might have done the job, but we wound up casting a whole new nut.

He came up with the 3D file for the split pattern and corebox.

You can make molding sand out of beach sand, ground up kitty litter, dog shit and water. It may even work. If you are going to spend your time mixing sand to make metal castings, you should be using the highest performance sand mix...

This was a test to see how the sprue, risers and gating worked. I also used 3000grit graphite to aide in release and flow.

I've been casting for a few years now and I do lost PLA/resin vacuum casts and ceramic shell casts. I mainly cast with silicon bronze to make sculptures and art, but I also occasionally cast simple pieces of jewelry too when inspiration strikes.

I got started learning to metal cast when I had a lot of trouble attempting to make copper plated art pieces with electroplating and decided to just give casting a shot, which ended up being a lot more up my alley.

I plan to learn...
