Casting exchange

I am looking for a project to cast and machine, but I don’t have a working printer, was hoping to be doing a steam engine but if you have something else useful for the shop in mind or a line on some machinable project patterns available in thingyverse or what have you, I would be interested in casting one for myself to try in exchange. Or any patterns y’all have already made and no longer need or already used I would love to get practice.

I have my dad’s patterns for a steam engine there are two cylinders of different sizes that could be used separately but are meant to be used combined for a compound engine.
I’d have to measure but I belive one is 1 1/2” and the other one about 2 - 2 1/2”

Sounds like fun, any plans for that?

The plan is to get it finished and up and running I’ll post some pics of what I have when I get back home from coffee.

Here are the cylinder patterns one bore is 1 1/2" and the other is 3" both castings can be bolted together.

These are the core patterns for the cylinders and steam passages.

No he had them cast I believe in Victoria or Vancouver. Last time I was in Victoria I stopped by a foundry that's about 4 blocks from Capital Iron on the otherside of Douglas if that makes sense! if I get out there this year I'll check it out more.
I'd like to give it a go though

I'm a little confused here .... as per usual.

You have a two cylindered steam engine with two different cylinder dimensions?

It's a marine compound engine steam enters the smaller cylinder and the exhausting steam is piped to the larger cylinder that's powered by the expansion of the steam each cylinder is also powered on the up and down stroke.
