I dug out of storage an old project that I started probably 25 years ago. It’s a Baldwin switcher using a Cary body casting and an Athearn (obviously Blue Box) S-12 chassis. It’s raised a few questions!
- Is there an instruction sheet somewhere on the Internet? Bowser doesn’t have it, and a Google search doesn’t seem to turn one up either. This doesn’t seem like rocket science, but…
- I discover that I had cut the frame apart, into a number of pieces. It appears that the Baldwin DS-4-4-10 must have a longer wheelbase than the S-12 donor. I cut the frame around the motor mount, apparently to move the trucks toward the ends of the new body. But I have NO IDEA what I needed to do, since that was done 25 years ago, with no instructions and of course I cannot possibly remember just what I was thinking…
- I did some Googling and found that the wheelbase of the DS-4-4-10 was in fact 3’ longer than the S-12 donor chassis, at least in the prototype. This isn’t the biggest error, and I would guess in 2012 that back in the 1980s (or in the 70s, the likely origin of the Cary casting, or the 60s, the origin of the S-12 model), three feet would be overlooked.
- Measuring the actual Cary shell shows that it’s 45’ long, generally consistent with the idea that the DS-4-4-10 is 48’ 10" over the pulling faces, as some Internet data reports.
- What probably is odd is that there are no extensions for the drive train, which obviously must be required if in fact the chassis needs to be longer. Ordinarily I would get all of the pieces for a project like this as I start it, so either I hadn’t figured out what to do or the drive train components were not available. (Perhaps that’s why I shelved it?) Does this conversion require chassis extension?
If I can’t work out what to do with the old Athearn chassis, what options do I have? Are the Hobbytown ones still available? Protopower West seems like a pretty expensive option. I
