Скачать или смотреть PM Research #1 engine with boiler #1 and ram

I bought this engine plant several years ago. It would
only work for a little while at a high pressure so I opened
the cylinder, removed the piston, and found a broken teflon
ring. Oopsie by the builder. There are supposed to be two
separate rings but there was only one extra wide ring.
So, I bought some graphite yarn, wound it in the ring groove,
and replaced the piston - it was now smoothly firm in the cylinder.
Tested on air ok, then to alcohol, a 4-wick burner, and you can
see the results, a pretty nice runner. I'm very pleased I was able
to improve its performance.
In my opinion, this #1 engine is too much for the #1 boiler to
sustain a good head of steam. Maybe if I had a much hotter
heat source it would be ok. I'll be speaking with a PM tech
soon on this.
