Toy steam.....yes, sometimes.

Precision scale models and full sized..... almost never.

Just for a bit......if it is not too old.
Old is anything older than me.
I'm past running at full steam.
Taking it easy.

I added a too-old and younger than me engine pix.

Is the first one a Bing? From the fire box I would say yes. Both look to be sturdy workhorses. :)

I avoid it with most engines, and am usually on the opposite end... seeing how slow I can get them to run.

I do run my little Mamod oscillators (like an MM2) full speed every once in awhile as those that show no interest get a kick out of seeing them run fast.

Sometimes just for very short periods, for no other reason than I can.

Mostly I'm the opposite, if the engine has no load I try and get it running and ticking over as slow as possible so it looks more realistic and for me its just all round more relaxing to watch CB.

the older I get the less I feel the need to run WOT, but usually a new to me engine will get some rpm's thrown at it to see if there are any problems, or to see if it WILL run at fast speed like I know it should, once I'm satisfied that all is well I don't usually run them vey fast again...no Joy in it for me.

Getting them to run slow is a challenge. Thinking about it, I do have an tach, so it would be interesting to post some numbers here!

25-30 rpm's is about the slowest I have gotten them to go...

26-27 rpm's here

Nick, I have watched a few Jensen 50's run, but I don't think I've ever seen one go as slow as yours...must be well machined and timed!

Running on steam or air?
I suspect steam as I see water.
Actually very interesting, so much of the energy is used, you get only water out of the tail pipe rather than steam...

Very cool and amazing. Can anyone go slower??

Yep steam, slowly turning the variac lower and lower before stalling. I calculated it to 26.4 rpms. A non-reversing Jensen 25 may be able to beat that...

I like the sound of my J55 running slow to moderate speed.

Forgot to mention though, my Stuart BB is another story, that is meant to run full speed and sounds great doing it  8)
