thanh-cuibap, that's a fine looking motor, it runs well. It will be interesting to see how well the aluminium piston lasts in the steel cylinder, it's not the best match of materials from an engineering point of view(don't let that worry you), the best metal for a piston is cast iron, but not always easy for some to get.

Absolutely Amazing Thanh. You have done a nice job on the machining work and I do love the flywheel.
Was it easy to balance the flywheel after adding the spokes? Every time I try to make a spoke wheel, I end up throwing it away in frustration. I am now using aluminium pulleys as they are reasonably cheap.
I will be at our Gemfest for the nest few days in both my town and Cairns. I will be looking forward to hearing how you go with it all. I have learnt a lot from Ian re the alloy and steel together. It does seem to work OK, though the alloy expands a lot more and seems to tighten up after a bit of use. Actually had to sand the alloy piston a bit more to make it work better in higher heat levels.
