Okay .... I think by now that most of you know that we have moved to southern Indiana and are currently renting a house while we are building our new house.

So I still have days when it's raining or it's just to cold out to work on the property and I never have been one to sit and watch TV much.

The rental house has two bedrooms and we have set the computers up against one wall.
Against the opposite wall, I set up a folding table and made a couple of storage shelves out of some old closet doors so I can still play with my trains.

SAM_0855_zpsqetnqx4y.jpg


I actually started this little project about two months ago and hadn't taken any photos back then.
Now that the weather is turning colder, I'm spending a little more time on it.
This is another different type of engine made from cutting the parts from the plastic AHM 0-8-0 locomotive kit that was available back in the 70's.

I like locomotives at the opposite ends of the size range.
The big long articulated steam locomotives appeal to me and the little 0-4-0 switch engines appeal to me.
I'm not so much interested in the locomotives that are in-between those two sizes.

For this one, I took the AHM 0-8-0 chassis ( on the left ) and cut it down to a 0-4-0 chassis.

SAM_0852_zpslcnrayk9.jpg


Now the boiler from the 0-8-0 locomotive ( on the left ) is too large for the switch engine so I only used the cab and part of the fire box under the cab,
The floor of the cab is made out of diamond plate patterned styrene sheet and front of the cab is made out of smooth styreen sheet.

The boiler is a section of 1-1/2" diameter PVC sink drain pipe and the larger diameter in front of the cab is PVC pipe coupler.  

These two pieces were glued together and the taper into the larger diameter was turned on the lathe.
The banding straps are .100 wide styrene strips wrapped around the boiler.  

SAM_0853_zpshvu8p6yu.jpg


The front section of running boards were cut off the AHM kit ( on the left ) and glued to the boiler on the switch engine.  

SAM_0854_zpsmrgcsh3n.jpg


The steam cylinders on the 0-8-0 locomotive have three cylinders ( on the left ).
The switch engine uses only two steam cylinder so I trimmed the center cylinder off and smoothed the steam cylinders down.

SAM_0851_zpsx2imycix.jpg


Put these parts together and it looks like this so far.

Nice looking little engine.  I have all my G scale train in storage right now.  Most are on shelves, covered inside the signal control building.  got it mouse proof and have 4 bags of poison down just in case.  Four of the engines are in the basement on shelves along with one stock car.  Later this winter I will build some more structures out of cedar.  I still have a pile of cedar strips inside the machine shed I can use.  Also have repair work on several buildings.  Wet or dry course sand paper does not stand up to hail.  Takes the rain fairly well but the hail really tears it up.  Now I have about 5 roofs to redo.  Nothing like working on your railroad while the snow it blowing.

The steam dome, sand dome and smoke stack are mounted on the boiler.

SAM_0856_zpsjei2ev1y.jpg


The smoke box front is also in place.
This smoke box front is what got me to build this engine.
 
I had bought some brass parts off ebay and this smoke box front was in that batch of parts.
Looking at the photos of the parts on ebay, I thought this was a brass smoke box front that had been painted.
When I got the parts I realized this front piece is plastic.
It is the same diameter as 1-1/2" PVC pipe so I decided to build this little locomotive with it.

Who else do we know that can build a model train out of a water drain?

We have had some cold and rainy days lately when they haven't been working on the new house so I have gotten some time on the engine.

Finished assembling the drive linkage on the chassis.

SAM_0858_zpscijo4kef.jpg

SAM_0859_zps5qineefp.jpg


The plastic air pump that is in the AHM 0-8-0 kit is a two cylinder pump and this little engine uses a single cylinder pump.
I'm using a brass air pump from my parts box and I bent a piece of flat brass to fit the curve of the boiler and soldered it to the back of the pump for a mounting plate.

SAM_0968_zpswvestvlp.jpg


The air pump is fastened to the side of the boiler with two screws on the bottom of the mounting plate.
I shot some paint on the boiler so it would be painted behind the pump.

SAM_0969_zpsz7rhl8kr.jpg


I'm using the plastic running boards that were on the 0-8-0 locomotive.
A piece of wood is mounted in the small vice and the running board is clamped onto the wood.
This holds the running board in position for gluing it to the side of the boiler.

SAM_0970_zpsworwefmc.jpg


A piece of flat styrene is glued in place to fill the space between the running board and side of the boiler.
I found out the styrene glue won't work on the painted area so I had to scrape the paint off the boiler behind the running board.

SAM_0975_zpsid9hpffm.jpg


The air line from the pump to the air tank is formed out of a piece of brass rod.

SAM_0976_zpsrbvht6gl.jpg


Two thin strips of brass are soldered to it to form the mounting brackets.

SAM_0977_zpswdy6r2oy.jpg


The air tank is mounted under the running board and the brass air line is fit between it and the air pump.
The rest of the lines for the air system are formed out of round styrene and glued in place.

Nice progress Ray. Any reason why the brass is all being painted? I think brass accents the engine nicely.

Just my personal preference.

On the locomotives that are a mix of plastic and brass ( or other metal ) parts, I like them painted so they are a uniform finish.

The locomotives that are all brass I like to leave un-painted for the uniform "brass" finish.

Winter has come to southern Indiana with snow for a couple of days so this gives me a break from working on the house.
Today I spent working on the model locomotive.

On the left side, I added the piping under the cab and drilled the holes along the side of the boiler for the hand rail stanchions.

SAM_0997_zpslcu8bbde.jpg


The headlight is mounted  in front of the smoke stack and the lift bar linkage for the coupler is mounted down on the frame.
I also added another pair of steps under the front of the running boards.

SAM_0998_zpshg0pjnka.jpg


The piping is put in place on the lower right side and the steam generator is mounted up on the side of the boiler in front of the cab.
The holes for the hand rail are drilled in side of the boiler on this side also.

SAM_0999_zps1ag6tysj.jpg


The draw-bar for the tender is mounted under the back of the cab.

SAM_1000_zps4diqfps1.jpg


The bell is mounted on top of the boiler behind the smoke stack.
This finishes up the engine and it is ready for painting.

SAM_1001_zpsmksmxziz.jpg


Next to work on is the tender.
I'm going to use the slope-back tender from a 3-rail Lionel train set and convert it to a 2-rail tender.
I'm also going to make some modifications so it will have a little more detail.
