I would find a oscillator design you like, use the above diagram to make a drill guide for the ports on the trunion and make it! Check out a few of the designs on Jon-Tom, or Google Easy Build. Hardest decision should be whether to build vertical or horizontal...

That's exactly what I'll do. I'll make a drill pattern from sheet metal at work and crack on. It will be a very simple stand up engine on a brass upright, just to get it going. Thanks very much.

Glad to be of help. I started figuring this stuff out trying to design Brian Rupnow's double oscillator. I figured it can't be that difficult, and I'm too cheap to buy the plans... I asked around on the various forums and got bits of info here and there, found the simulator, and decided to draw up the layout to help me make the model. It's still in the design stage... I enjoy learning Fusion 360 as much as building engines. I am drawing up some engines and things I want to cast in Aluminium, and 3d printing patterns for them. Good luck and remember to post your build!

Looks like you have a plan!

This afternoon I had a couple of hours in the workshop. I milled the piece of brass which will form the stanchion, this still needs to be cut to length. I also made a drill spot template from a piece of offcut sheet steel using the diagram posted by Chucketn.

Speed takes a back seat to progress every time! Looking good!

Thanks Chuck.
I went for a fairly simple built up job. It runs true and won't take much load.

You should be able to run that engine on breath power. Did you turn a relief area on the port block?

I haven't touched it yet Chuck, save to square up some stock. I will be doing that though.

Made a bit more progress, stanchion part machined and bored.

It does work! Runs well on air. Still some work left to do. I need to work out how to post a video.

Hopefully this link to my YouTube channel works:
Hope it's acceptable to link this, the video was too large to upload.
