Hi Noel,
Here's my a pdf print of my O5 CAD drawing that I
started. Had a long ways to go.
If you find anyone that starts working on it, I
might be willing to collaborate. But I realized the
monumental task of drawing it up in 3D and the
number of questions and issues I had. I would need
to live near one of the O5's and spend a lot of time
measuring and drawing. Overall prints like this are
one thing. But there is a lot on info needed that I
cannot discern from them.
Now if I had individual component drawings, it would
be a bit easier. I would love to find the frame
drawing. In my live steam build desire, I realized
that the one piece engine bed was a big difference
from the "bar stock" style of frame of older
locomotives like the O1a. And since 4960 was the first
steam locomotive that I rode behind, it was an easy
decision to go that route.
I don't remember if I sent a pic of my frame. Anyway,
see the attached. It won't be 100% accurate. Like the
drivers between the Heavy Mikado and the O1a are 1"
different. That equals 0.133" in the 1.6 scale live
steam model. Close enough for me. Main axle spacing is
identical.
Maybe it will be on wheels by Cabin Fever and I can
bring it up. But probably not, I just don't have enough
time to put in to it.
Where do you live?
Dale
