Oscillator Cylinder Pattern

All these oscillating steam engines everybody is building or renewing now...... makes me wish I was, too. My shop is basically unheated and temps outside this winter are no fun for me. I do have a little electric heater out there that struggles to alter things for the better, but the cold concrete floor just sucks heat out of my boots. Anyway, enough complaints!

Maybe instead of a complete engine I thought could just start on one thing -- maybe just a pattern for a cylinder. No chance of casting until outdoor temps are better and some of the snow is gone. But just the pattern might be fun for now, and make me feel like I'm doing something. And I can probably duck in and out of the shop, and do some of the work inside the house, since wood is my choice for pattern making.

I'd like something decent size, maybe inch and a half bore or so, I'm thinking. I don't have any 3" dry clear square stock to turn it from, and besides I was thinking last night, what if I tried assembling it out of pieces I cut out of scrap pine using my collection of odd size hole saws? String the pieces together like beads on a 1/4" dowel. Shish-kebab cylinder. Seems like a doable way. Could be fun.

So I picked through the saws I had and came up with a set of three, that seemed close enough. I started drilling. Or sawing, or whatever you call it. Trepanning? Anyway, making sawdust in the process, and not in the metal lathe for a change.

Just a test of stringing them together. I'll trim some of these down a bit, maybe the core prints and the flanges. But I think this will work.

To add a trunnion face, I took one of the plugs and sandwiched it together with three other pieces of wood, then drilled with the hole saw down into the end of the face to make a hollow:

And another mock-up of the rough cut pieces together:

This is great, I'm glad you have found something you can do during the 'cold times' and I'm fascinated by the process so you have me hooked and following along :popcorn: :ThumbsUp:
