Elmers scotty , 2x scale

[55fairlane]

Built this couple years ago, never could get it to run. Talking to a couple people at our show, I finally figured out, these need a HEAVY flywheel,  I personally thought the flywheel I grabbed was stupid to big......nope, runs smooth as glass on about 12psi. I personally don't think that's bad for an engine with ¾ inch bore, it uses a big volume of air.
The flywheel,  the cylinder & the yoke were finished with "cold blue"

Always Great to see them Run - especially if you had a lot of problems to overcome

I love the beat and the sounds, well done, especially if you had trouble with it and finally got it going

Love the 2x Elmer's models!
 The parts are easier to make when you have old eyes like me

Good to see/hear it working.  It's not a favorite for me, but that's the anal efficiency-loving engineer talking...
