Its taken me a while to finish this engine, it sat for a number of years on display and I kept thinking that I need to add a lantern. Finally I decided to do the sheet metal work for the lantern, really as a trial before I build the main body for the traction engine project that is also on the workbench.

Lantern

This also meant I needed to add a generator, I created a simple swing arm and used a small electric motor driven from the flywheel.

Just need to now share a video of it running. The light bulb was turned out of perspex and a small LED fitted inside - some hints on machining perspex.

Thanks for the kind remarks, I will create a youtube video of it running as it does come to life even on compressed air. The original engine was inspired by a MalpressPeake engine design.

I'm now creating some plans for the complete design, although this may take some time.

I did play with a few different motors to find the right one, there are some larger diameter small motors that work quite well.

It is an interesting engne on its own but the lamp standard is a great twist.

Perhaps you can hide the wires, or at least make them cotton covered to be in period.

A very nice and unique engine, look forward to the video of it in action.

Way cool. Imagine a world with one of them chuffing away on every street corner. Heaven.

Well done Nigel, a really interesting design. Can’t wait for its serialisation. Maybe in MEW ? It’s certainly a project I would like to embark on, when I get other jobs off the bench that is !! Cheers for sharing it.

Very nice indeed. I love the way the generator runs off the rim of the fly wheel, makes for a very neat and compact installation.

Very nice.

Another little tip for getting a clear finish on perspex or any other type of acrylic is the same as you did with the sandpaper is when finished use something like T cut for cars and rub that on while the lathe is turning. I make pens using acrylic but I use Burnishing cream which is basically the same as T Cut. Even for the drilled hole this can work but use a wooden dowel with it

Really nice engine and a nice unique idea. I don't think I would ever try this myself but I believe you can polish acrylic with a naked flame!!! Flame polishing!
