Another Stuart Progress

[Mark_1984]

I've started building the Stuart Progress Oscillating Engine.

I started with the flywheel, which was a really nice casting. I machined all the dimensions by eye apart from the diameter. I've videoed the machining, but I forgot to take any still pics! Sorry. I'll try harder for the next update.

I held the flywheel in a 3 jaw chuck, on the inside of the rim which gave me a nice, very true running inside rim. The rest of the process was plain sailing.

I like the looks of that engine a lot.
Very graceful design.

Thanks. I do have a soft spot for the more authentic looking oscillating engines.
I have the Crosskill's Oscillating engine ready to start as the next project. That kit is available from Polly Model Engineering.
