Very nice cab, it's really coming along Ray !! :thumbs:

 

I like the way you pushed the rivets thru the roof.

Thanks for all the nice comments. ....

I've "kitbashed" several locomotives out of plastic over the years by taking parts from one kit and mating them with parts from another kit but this is my first attempt at building an engine by making so many of the parts from sheet styrene.
It certainly has been a learning experience.

The railing for the front running board is formed from brass rod.

SAM_0501_zpsfxndu7tt.jpg


Then I drilled holes in a piece of wood to make a jig for soldering the support bars to the railing.

SAM_0502_zpsvensyrxz.jpg


Here how the railing looks on the engine.

SAM_0507_zpsgjd2vzuc.jpg


I've also finished up the piping on the front and added the bell and smoke stack.

The boiler and cab are finished on this locomotive.

I'm using a brass smoke box front cover and I mounted the number plate in the center of it.
Also added the two clearance lights and the headlight then I mounted it on the front of the engine.

I also put the hand railing on the lower part of the front and along the sides of the boiler.

SAM_0525_zpszewr24cc.jpg

SAM_0528_zpse3xkvnmj.jpg


On the rear half of the boiler I put all the hand railings on and the two step plates on the lower part of each side of the fireman's cab.
Also put in the washout plugs along the sides of the boiler ( small round brass things ).

SAM_0527_zpsa7fu5xzv.jpg

Now it's time to work on the two chassis assemblies.

Is that the final product, or does it get paint? Either way it looks awesome . Great talent you have , and a lot of patience . Tom

This will be spray painted and obviously, I will have to spray it at a lot of different angles to get around all the piping.
The cab is not glued to the boiler so it can be removed so the area under the cab and the inside of the cab can be painted.

Scratch building a plastic locomotive like this isn't like building one from a kit.
This doesn't have parts with a tab-A that fits into a slot-B so you could paint individual parts and then assemble them.
All the parts are flush mount and the styrene glue wont hold if there is paint in between the parts.

Luckily, everything gets painted the same color so I just I just have to get it in and around everything.

Working on the rear chassis.

This is what the front of the steam chest for the AHM 0-8-0 model looks like.

SAM_0548_zpsqbbyx1zj.jpg


The steam chest is modified some to look more like the steam chest for the Erie locomotive.

SAM_0530_zpsjicnbzv5.jpg


This is how the side rods and valve linkage looks on the AHM model.

SAM_0533_zps5jzenomk.jpg


This also had to be modified a little to closer match the linkage on the Erie locomotive.

This photo shows that the front steam cylinders are a larger diameter than the rear steam cylinders
They also have a square valve case on top instead of the round cylinder valve case.

The difference in the diameter of the cylinders is because the rear cylinders are for high pressure steam and the front cylinders are for low pressure steam.
The steam from the boiler is piped to the rear cylinders first.
Then the exhausted steam from those cylinders is piped up to the front cylinders so the same steam is used twice.

Starting with another steam chest from the AHM 0-8-0 plastic model.

SAM_0535_zpstlekpaqa.jpg

SAM_0536_zpsy0xcbstf.jpg


The round valve cylinders are cut off the top.
The two PVC pipe fittings will be used to make the larger steam cylinders.

SAM_0541_zpshpfzbi7k.jpg

SAM_0542_zps5a9z0taj.jpg


A groove is cut into the side of each PVC fittings so they can slide over the steam cylinders.

SAM_0544_zpscb8b1ctt.jpg

SAM_0543_zpsud5r8qna.jpg


Then pieces are cut out of another PVC fitting to fill in the gaps.

SAM_0550_zpsdsnpefm1.jpg

SAM_0549_zpsvschyuut.jpg


A square valve case is made out of sheet styrene and glued to the top of each cylinder.
Pieces of styrene with a diamond plate pattern are glued to the top of each valve case and to the area in-between the two steam cylinders.
The cylinder end caps are also made and glued on and a side plate with rivets is added to the outside of each cylinder.

SAM_0556_zpsrqmcoh7j.jpg


Here is how the new steam chest looks when painted.

Another question Ray. Does the styrene come with diamond plate pattern, or did you make that too?

The styrene sheets come in all sorts of patterns.

Besides the diamond plate, there are brick, field stone, roof shingles, siding and different widths of  wood planks.

There are a set of steps on the frame in front of the front steam cylinders.
I cut four pieces from a piece of brass with the diamond tread design in it and bent up the edges on each piece to form the step plates.
Then I cut two strips of brass and formed them to make up the side plate for the steps.

SAM_0585_zpss2tqf96u.jpg


Here's how the steps look all soldered together.

SAM_0586_zpsfuqf3qiq.jpg


These steps are fastened to the sides of the front chassis frame.

SAM_0589_zpsso9kj7ui.jpg


How they look with the steam cylinder mounted in place.

SAM_0587_zpsbvtwf2zi.jpg

SAM_0588_zps1sqjljs0.jpg



Two linkage pieces are soldered together to form the right angle reverse lever.

SAM_0590_zpsqqvcnzfg.jpg


I glued some pieces of wood together to make a jig to hold the brass rod so it can be soldered to the reverse lever.

SAM_0591_zps7kvscfoh.jpg

SAM_0592_zps3ia7kmgd.jpg


Here is the reverse lever with the rod soldered to it.

SAM_0594_zpsvbxbnj29.jpg


The reverse lever and operating linkage rods are mounted on each side of the boiler.
