[modeleng] Re: Ga1 experiments. Does LBSC "Tich"*0.66 = LBSC "Small Bass"?

Hmmmm very interesting. While it's very 'Tich like' in some ways, there are
some fundamental differences, notably the inside valves and the shape of the
frames. O/a length & boiler diameter are about the same as a 'full size'
Tich. What I'm looking at doing is actually scaling the whole thing down -
around 8" long over the beams & a 2" diameter boiler. That boiler, BTW, will
come out at only about 120mm long - cut a piece of stock for the barrel
today, figure if I can get the boiler working ok in that size, then the rest
will just naturally fall into place (well, that's the theory any'ow).
