I spent a little time today filming and putting together this compilation of some of John McDivitt's model steam engines that are capable of running on a small aquarium pump.
Enjoy,
Gil

They all just kept building on the last one , when I told myself "thats the one I would like to have" ...a better one would pop up. The Major beam is still in my top 5 for most desirable engines ever. 😉👍
Thanks for taking the time to video these lovelies for us Gil.
Some very special engines Gil

Wish there were more builders with John McDivitt's skill as it's very hard to fine such nice pieces
Not sure, but is it possible you have THE collection of John McDiviitt engines...his workmanship is beyond compare...just gorgeous.

Such precision and attention to detail is truly embarrassing to those of us who only pretend to do a little machine work occasionally.
Wonderful engines Gil, you are a lucky man to have such Jewels in your collection!

What Daniel said , totally agree 😉👍
Very hard to pick a favourite amongst that lot!, i love the slow motion of the Major Beam.

I take it these are all run exclusively on air Gil?
Gil , Thanks for posting the video it's always nice to see John's engines running , sure do miss him .Jeff
