Steam Engine Paterns Update

I figured I would upload this since the patterns are all finished and ready to be cast when the weather gets better. Ive almost finished the flask for the main frame since it’s bigger than any flask I had. Just need to add some screws so it’ll never come apart, make some waterglass, and refill my co2 tank to make the core for the engine cylinder.

Here’s the pics.

 

The patterns are smooth as glass, and the sand just falls right off of them, so they’ll be a piece of cake to mold. (famous last words, lol) There’s around 15 parts to be cast out, and around 5 of them will be done in bronze, rest will be done in aluminum for now to get a prototype made, then will be cast in iron.
