In the thread I just did on the brass locomotive, I had talked about getting started on trains by "kitbashing" the plastic steam engines that were available back in the 70's.

The main engine kit that I used was a model of the Indiana Harbor Belt 0-8-0 locomotive.
These were made in Italy by Rivarossi and sold by AHM.
The model kit was sold with plastic wheels and they made a motorizing kit that had metal wheels to replace the plastic ones.
Here is what that engine looked like when assembled with the motorizing kit.

0-8-0_zpsmve3yecj.jpg


Over the years I have managed to collect several of these plastic engine kits and the motorizing kits to go with them.
Using parts from a couple of these model kits, I would like to build a model of an Erie Railroad  0-8-8-0 Camelback  steam locomotive like this.

These are the main parts that will be used to build the engine.
An engine boiler shell and a tender shell.
Two frames, one with the motorizing kit already on it and an extra motorizing kit for the second frame.
Some miniscules plastic parts and metal side rods and valve linkage parts.
A cast brass boiler piece for a Camelback locomotive ( this will also add the necessary weight in the back to balance the engine so it isn't to front heavy ).   
A piece of plastic pipe to use for extending the boiler.

The first step is to cut the front part off the frame that will be used as the rear chassis.
Then I cut the rear part off the frame that will be used as the front chassis.

SAM_0422_zpsmeqopoic.jpg


I formed this piece out of sheet brass.
It will attach the two chassis units together with the brass shoulder bolt.

The brass piece fits on the back of the front chassis frame for the pivot between the two chassis frames.

This is a view of the underside of the two frames attached.

Here are the two frames set upright.

Sweet Ray, another build. :dancingbanana:

 

Looking forward to following along.

 

That was a monster of a machine.

Do you have any specs on it? They're probably mind boggling.

Thanks Ray.

Yep, that's mind boggling.

I bet the ground moved, when that rolled through town.

The cast brass firebox has a stub section of boiler on the front of it.

SAM_0436_zpsguxjxe4q.jpg


The plastic pipe that I'm going to use for the boiler is just a little larger diameter than the stub section on the firebox so I can bore the end of the plastic pipe out to fit on the firebox.
Unfortunately, I only have the small hobby lathe so I can't put the whole boiler in it.
I cut a short piece off the end of the plastic pipe and chucked it up in the lathe to bore out the end.

SAM_0427_zpstzvlhzyl.jpg


This end piece now fits over the end of the firebox.

SAM_0429_zpsu9w1yrcy.jpg

SAM_0430_zpslkwz2auw.jpg


The end piece is then glued back onto the end of the boiler.
I scribed a line on the side of the plastic pipe before I cut the end piece off so I could align the two pieces back the same way.

Looks good. Will that be the finished length for this?

That is the finished length of the boiler.

The locomotive and tender will be about 25 inch long when it is all built.

 

Here is a straight on side view of the locomotive.

After doing a little research I came across this explanation of why these locomotives were built this way.

" The Reading, Lehigh Valley, CNJ and several other roads used camelbacks in all types of service including passenger.

The reason for the wide firebox was so the anthracite coal used by these railroads would burn more efficiently. Anthracite is a very hard coal compared to the bituminous coal used by most roads and required more air and a thinner layer of coal on the grates to burn properly.

The disadvantage was that they were so wide the cabs had to be located over the boiler exposing the fireman to all the elements and causing a communications problem between him and the engineer. "

Right now the top of the boiler is even with the top of the firebox.
You can see in this drawing that the top of the firebox sets higher than the boiler and the rear portion of the boiler flairs out going into the firebox.

photo%20-%20drawing_zps5ykmvzfp.jpg


Using automotive body fill, I added height to the top of the firebox and tapered it down to blend with the boiler.

Here is the finished boiler.

It must have been uncomfortably hot riding that close to the boiler.
