Very nice Dave. To get something that samll to run at all has got to be quite an accomplishment. :thumbup:
Sounds like an angry bee. :)

A little more information cause someone asked:
Thanks for the appreciation.
Bore and stroke 1/16 inch
Crankshaft built up using .015 music wire and a piece of .025 inch dia. sewing needle.
Boiler is spun copper as I couldn't find a usable thimble.
Plans were published in the book "Steam and Stirling Engines You Can Build" published by a division of Live Steam Magazine in 1980. The article was titled "Thimble Power Plant" by Dr. James R. Senft.
I don't know if copies of the magazine article or the book are available.
I hope this helps.

Dave,
A real nice runner you have there. I don't think my eyesight will work with things that small any more
Almost a couple of years ago, I knocked one up in less than a day, but a lot larger than yours. In fact yours makes mine look massive (no I'm not boasting again).
Based around Tubal Cain's porting for the Jenny Wren. If I can remember rightly, it is 3/32" bore by 1/8" stroke, or it might be 3/16" stroke. The brain cell is fading fast.
They really are nice little exercises to do. My main problem was silver soldering the syringe tube in for the inlet pipe.

Dave, how on earth did you get that thing to run? And on steam as well, it's minute! It must be a very low pressure too.

He first "crushed" the water molecules down to size. Almost to a fine dust before heating into steam!

Oh No, had to get the kid to run the screen over to the TV so I could even see that tiny.
Excellent Job

Dave, do you know if this was also published in Live Steam magazine too ? If so, remember which issue it was ?
Thanks,
Mike

All the Steam and Sterling articles are reprints from Live Steam Magazine, the article in question would have been from before 1980. Sorry, my archive doesn't go back any farther than that.

I Googled it and found an eBay reference to it using the keywords "Thimble power plant live steam magazine":
Live Steam Magazine October 1976.
It was sold. The book is probably your best bet.
Warning it can cause eye strain! :bugeye:

No worry, I've got every Live Steam magazine from 1967 to the present and some of 1966 :thumbup: I'll look it up !! Thanks for the pointer :)

Got the Oct 1976 issue and plans :thumbup: Lots of details & drawings.
Heck, there's even a few foldout pages in this issue (not related to the Thimble build). Allen locomotives catalog was $0.50 back then, now it's $5. Not too bad for inflation :ddb:
