Is there any books or articles that describe the process of scratch building a engine? I always wanted to build one frame up. What really goes into it?

Basically a WHOLE lot of design work! Are you working from plans, from old drawings, or by eye? How true to design are you going to be? You have to pick out the drive system, design a solid frame that will fit and look good under the scale model, then make attachment points for the axles and trucks. THEN start work on the steam boiler or diesel car body. I'm assuming you're doing steam  . Plus you need some pretty good soldering or welding or molding skills to make some of the stuff. I dare say I doubt I'd ever have the patience to scratch-build ANY kind of locomotive. Wish you luck and patience in that endeavor if you try!

Model railroader ran a series back int the late 1980's, early 1990's i think. ... or maybe it was later... I think this is the series compiled:

I have this very large PDF file I could maybe email you:
http://www.amazon.com/Steam-Locomotives-Project-Ideas-Railroader/dp/0890244006
It has a scratchbuilding series for this 4-6-0 in it.

Gareth,
Scratchbuilding steamers is AWESOME but I hope that "Avatar" is not just a hoax.....LOL As your gonna need a Unimat, and then some to do the whole thing! I have a Unimat and a bench top 10 by 28 in my basement!
I actually have plans to build a set of cylinders for a Shay 3 cylinder job, just to run off compressed air, just like the real thing! 
I know, I know......... I can't help myself!

Hey John:
I actually have two Uni's both DB200's. Having a speial base made for one to allow the Millimg column and headstock to be mounted behind the mid-point of the ways to allow a milling table travel in what will then be "X" of some 6-8 inches. I have a powerfeed for one of them and a dividing head. Slow speed bracket is next then an independant 4 jaw chuck and one day a small heat treatment oven!
I'll eventually get a Taig with a 12"+ travel in X to allow milling of longer locomotive frames in likely brass....
Like to get a Cameron Collet equipped Micro-drill as well....
I have access to full blown commercial eqipment at the college I attend part time...

I've got the SL200, and all its attachments, along with the regular machine toolong I have as I have a small bridgeport in the basement, thats also a tabletop mounted machine, along with the larger look alike Micromark 10x28....
Your a lucky guy to have the dividing set up for the unimat! I'd love to get my hands on one! BUT I do have the the raiser blocks for the tailstock and headstock in the lathe set up.
I am not to fond of "power feed" on anything as I've been taught, Aprentice hands on.....All the tools I ran and learned on were old "belt drive" units made electric power!
Speaking of which, the Uni....I'd LOVE to also get my hands on a collet set for it!
Speaking of, we are gonna drive these guys in here crazy with the machine talk as I've done some crazy stuff over the years.....Alittle kick you might get.......see your PM's!

Hey John:
Got an excellent deal on the dividing head.
As to the powerfeed, welll handis nice but if you're cutting a thread or looking for a high level machined finish you have to go machine feed.
Didn't know Bridgeport made a Mill small enough to table top...!?

Gareth,
Yeah I've looked for the dividing head and have ran across them on "addiction.com" (AKA Ebay) and was $250.00 to $500.00! WOW! I didn't pay that for my machine.....
As for the power feed, I do have that one the lathe I have in the basement. The Uni, I use for designing and such, thats why its all hand feed, and not auto.
The Bridgeport, well I ought to say it weighs in at like 400 or more pounds so its not all that small.....I bet it stands from the table top surface to the top of the headstock motor about 4 feet....So its not that small. Its the size of machine that would come with its own stand that it sits on, as it has.....I just made it from angle iron and tubular steel to support it.
My original Bridgeport, weighed in at 4,800 pounds, but when I decided to move, I sold it!
