Wow. 8000 hrs on steam! I just ordered a new #50 and plan to run it continuously while I’m in the steam shop. Sounds like I’m trackin. Thanks for that reply.

Sounds crazy but a low cost tiny well built engine like that makes me want to bolt it down and run it continuously 24-7 as an endurance experiment. Figure out a way to put tiny amount of lube in its air and let it run mid speed for 3 months then tear it down for wear check. Maybe I have a little twisted streak, but it would be fun to see how much abuse it could take from somebody that knew how to do it right. Maybe an oil bath crank, it would end up a holy mess blown off with an air hose and washed down with WD 40 once per month.  It must be late, goodnight.

Hi Tim,

Along that line of thought, how well would a mamod or Wilesco or Jensen hold up with continuous running for several months.
As for the Jensen 50, we know of one that is on the #51 prototype that was run 24/7 for over 8,000 hours straight on live steam and it still runs great today. I know there are Mamods and other Jensens from the 1930's and 40's that still run nicely today although I have no idea of the amount of run time on them. Jin's machine work is of a high standard. The little v-twin is a larger version of the one that Philcraft made from plans in the public domain.

by the time I had filmed  that Tim it had probably ran 3 hours continuously at a slow speed, I was hoping it would break in a little more and become a self-starter, neither of those things happened...it's just the nature of the Beast, I find that common with very small engines, too much friction to overcome for too small of displacement 😊
the only thing I would have changed on this design was to add an oil port on the axle shaft support tube.

I've had that combo on my watch list for a month now Dave, and every time it's come up it's sold for about $59 and I've just missed it every time...but they come up often and I will snag one sometime.

Thanks, for that, Bruce!

You certainly scored a great value!

I have Jin's mini beam engine and boiler combo, it's a lot of fun to run.

Good to see one running, and some good deals can be found on Jin's auctions...

fun little engine, & for $25.50 (inc shipping) I consider it a good buy, I don't know what I'll do with it ,  I have the little beam engine coming in a couple of weeks.
