Jim, Bill,
It was just 10 years ago when I completed Ray's #3 Mill engine, my first steam engine. That started a journey into this hobby where I've met so many great fellow model engineers.
I've seen the #3 Mill engine at half scale and I've built it in 1x, 1,25x and 1.5x scales. I often run the 1.5x engine with live steam at the Rough & Tumble shows
Cheers,
Phil
