Beautiful!

It's nice to see how smooth and slow it runs.

Beautiful work there Geoff, well done.  IMHO a good decision not to paint it.

Thanks for all the kind replys guys
here's a bit more about the govenor which i was a bit unsure about because my engine is a bit different to the plans, after a bit of thinking i dived in and came up with this solution. when i just had the govenor and no linkage connected i found when a certain speed was reached the balls flew out and stayed there untill the engine speed was quite slow and this seemed to make sence with the centrifugal force applied.  But when i had added the linkage the weight of it made the action more progressive. The thottle valve is simple with a 1.4mm hole drilled thru a rod which is turned by the govenor link to misalign the holes, the pic shows how to go about setting it up while the engine runs, a small hole in the backnut shows the position of the valve and i have stuck a drill in there so i can see its position and lock it in suitable place. you can decide yourself when you want it to cutoff, it does work  but the video i did was a bit shaky trying to hold the camera and play with the air control

When I was building this engine I had to make a few compromises as I decided to use a cylinder I had already made and also the base had to be made differently as I wasn't using castings, I was very pleased with the finished result but you do have that feeling it should have been better. so I decided to do some of it again to see if I could improve it. So here is my second attempt, I like the idea of the pipework going into the base and I've used smaller tiles, not sure about the colours though.

That's looking great Geoff. I am still working on mine and it looks like your second one I'd close to getting complete. Thanks for the tips I appreciate it.
