Hello, I have one of these Bowman-Bryant engines, which runs happily, although I just tested it on air. In a new build, i think it would benefit greatly from one or two piston grooves with orings or packing material inside. The original pistons are plain and those are always prone to blow-by. So...

The boiler looks great all painted and shiny. How are you going to paint the hull?

It runs and sounds like a clock :-) Very nice!

It sure does run nicely!

Slow, but nice work!

Hello, any news regarding this engine build?

Yes you guessed right! ;D Actually there is enough material to cut a groove into, below that lip there is a considerable ring of brass. I know that engines can run well without o-rings, but there is always blow-by. That means lost steam, less performance, and often a reduced ability to run...

Thank you for the advice. I'll try to cut some gaskets then. Still have to decide if paper or Teflon. Someone told me that Teflon gaskets creep under pressure? Did anybody experience that? I have managed to disassemble the piston+trunk and this is what it looked like. Lot's of dirt accumulated...

Hello again, I have started disassembling the engine for clean-up and also because I was very curious about the pistons. As you can see, it didn't have any gaskets and also no traces of liquid sealant. I guess whoever cleaned this engine up in the past and painted it, didn't run it, just kept...

Hello Pat, Thanks for the animation and info. I really hope to find out more about this engine. Meanwhile I am having a missing part made, so I'll hopefully be able to test run it soon. The plan is to build a paddlewheeler later on and to use this engine in it. Still have to determine what the...

Hi all, This is my first posting here, although I've been reading the forum for a while, with great interest. Now I need some help: I have an engine here for identification. Bought it recently (without any history) and according to my Internet research it is called a "trunk steam engine". As...
