EDIT: I added photos, description and fix to the bearing problem at the end now...
I'm soliciting opinions on the "length" flaw in the old Con-Cor 2-10-2...
So, upon looking at drawings of a 2-10-2 (not PRR) with 63" drivers (like the Con-Cor one), I notice that
the prototype wheelbase is 22', but the Con-Cor is 24'6". That's about .1875" (3/16") too long.
Looking at the mechanism, yes, it looks like they could have squeezed the drivers enough to get about 1/2 of that
out of there. A similar Kato Mikado, when you "5 driver" it, is 23', or .075, about 1/16" too long.
Compared to a 5-drivered Kato, we are talking about a difference of .1125 ( < 1/8" ). Or put another way,
the Con-Cor vs 5-driver Kato total wheelbase is 1.8375" vs 1.725"
Is 1/10th of an inch spread over about 1-3/4 what folks hate about it? Or is it the excessive boiler length that's
the killer here?
