So, what scale is it ?
No 3's design was strongly influenced by ET&WNC's #16, an 8 ton Plymouth but it is NOT A MODEL of that unit or any other.
Indeed, No 3 is not a model at all. It is an experiment into how small a real industrial locomotive can be. There will be no "scale" details. No scale grab-irons, no scale walkways. No fake louvers or pipes. Everything on it will be there because it's needed and "scaled" to be used by full size people.
Simply put, it will be a quarter ton, 7 1/2in (narrow) gauge, gas mechanical locomotive. Period!
This little critter is to railroading what ultralight planes are to general avation. 
PS: Go back to bottom of page 9, to see drawing. Bob

Work continues. The cab is all welded, ready for sheet metal skin.
The design is evolving as we build. This is the latest version. Bob

NO, THIS IS NOT A DOUBLE POST!
The design keeps evolving as we build. It is hard not to think "model". We really don't need a grill on the nose; there will be a round fan (electric) on the hood to draw air up through the open bottom past the motor. "No grill" is stronger, easier and provides space for the front light.
I've figured a way to move the exhaust stack nearer the motor and added brace panels to each frame corner.

Thanks a bunch, Woodie!
In the US, 7 1/2 (and 7 1/4) seem to be pretty well all "scale". Either 1/8th or there abouts, full size, for standard gauge or 1/5th, give or take, for narrow gauge.
In Europe and especially in GB there seems to be (based on what I see on You Tube) a LOT of "micro-narrow gauge" (It's 7 1/4 over there, not 7 1/2). These, like mine, are actual 1 to1 trains - but, indeed, little ones. Look up "Moors Valley Railway" for a good example.
I think we'll all agree that narrow gauge is pretty cool. We don't usually think of the prototoype being less than around 15 inches of gauge.
But it CAN be. It can be half that.  xxxxxxxxxxxxxxxxxxxxxxxxBobxxxxxxxxx

Don't be bitter, Herb!
Did our first roll test today. Yellow lines indicate planed construction.
The motor had not been re-mounted in this view (sitting on floor in background)

Wish I had a video camera, Woodie.
This project is designed from the inside out. And it keeps evolving as we go. this may well be the final design. Tomorrow I plan to cut sheet metal for the hood section.
