Guys, thanks for all your suggestions though, I do appreciate you all trying to help. Her is the thing,
you can not build a large scale locomotive from a GA drawing, it takes a few hundred drawings to do it right. In the smaller scales like S, O, etc you can guess at some parts and that’s good enough because it runs on AC 110V, but when building a miniature steamer that runs on steam, you can not guess at the valve gear or many of the parts, some things you can change, but you have to stay close to the drawings or it will not work unless you stick to the drawings. The larger the scale the more drawings you need, and when you are spending a few thousand hours and untold money on your shop, machine tools, patterns, castings etc. you have to know you are doing it right or there is no way you can justify the effort and resources, that means you have to use the real drawings, if not all of them, then every one you can get and you can not start until you have enough to do the job. The K-27 probably has 250 original drawings and then another 100 when they changed from compound to superheat, the K-28 probably 400 from ALCO. The K-36 came from Baldwin with 421 drawings, and one of them is like the sectional view of the K-28 that Coranodo sells, I have that K28 drawing also, but that will not work in this circumstance, I would be approx. 399 drawing short. I am however really glad that you guys can model on a couple of drawings, but in my scale it just won’t work, I wish it would, as it would make things so much simpler!
Dave G., if you want I'll call your shop tomorrow and we can talk further.
