Spent most of the the day working on the valve linkage for the front chassis.

Putting a motor in this may not be as easy as I thought it would be.
I mounted a universal joint to the shaft on the back of the drive transmission today.
This only leaves a little under two inches to fit an electric motor in and still be able to fit the chassis to it's front and rear mounting points.

In order to be able to have a big enough motor to power both drive transmissions ( and all the moving parts ) and still pull some box cars,  I may have to put the electric motor in the tender and extend a driveshaft up to the transmission.
All my electric motors are packed away right now so I'll have to wait until after we move to finish that part of this project.
For now, there is a wood dowel attached to the U-joint so I can turn the wheels over by hand.

Awesome work Ray.

If you put a motor in the tender, can it be done with 1 more U-joint, and a bear in the loco ?

Not sure about O scale but putting the engine in the tender is not uncommon. Some of these designs were used with the Roco & Fleischmann locos in HO scale. Doing a kit bash like your doing you would have to keep the motor as low as possible to keep the torque down low to the tracks. These tenders had lead weights applied to keep from derailing. I would go online & research some of these to get some ideas especially trying to keep your drive shaft hidden yet functional. Putting the motor in the tender I think would be your best option. That O scale tender would also have plenty of room for a speaker if you go with DCC  :thumbs:

I have this tender that fits with the style of the locomotive and it looks as bad as what the engine shell looked when I got it.
The tender has cast pot metal sides on the top for the coal box and I would like to replace them with sides made out of brass.

Now I have a nice rivet press but it is packed away with the rest of my train stuff.
So I decided to make up a temporary rivet press using my drill press.
First I turned a piece of steel rod so it has a small bump on the end.

SAM_0386_zpsgkflg9pn.jpg


Then I drilled three small holes in the table on the drill press.
The one on the left is for brass and the other two are two deeper holes for working with a plastic sheet.

SAM_0383_zpswngg19vl.jpg


The small steel rod is held in the drill chuck and a back stop is mounted on the table top for an edge gauge.

Here are the test pieces in brass and plastic.

I've ordered some parts for the locomotive so while I'm waiting on those, I'm starting on the tender.

As a reminder, this is how it looked.

SAM_0387_zpsmcoopeur.jpg


The potmetal coal bunker sides and the water hatch have been removed.
Then I removed as much of the excess solder from the outside of the tender as I could.
Here is the main body of the tender after it is cleaned up.

SAM_0388_zps13oxaeqz.jpg

SAM_0389_zps2utz0q4t.jpg


I cut a strip of brass for the coal bunker sides and started putting the rivets on it.

SAM_0390_zpsmutuotd1.jpg


Here is the finished brass strip.

SAM_0391_zpsh5deg78n.jpg


The bottom edge is bent over to form and area to solder to and then the strip is bent to form the shape for the coal bunker.

SAM_0392_zpskqa6sbez.jpg


This is soldered to the top of the tender body.

SAM_0394_zpscwbl2xvl.jpg


The door for the coal bunker is made out of potmetal and I'm going to leave that on the tender.

Don't even have wheels on it and it's loaded already! Looks good, Ray!

Just WOW!

What Kenny said!

 

Back in '78 I started building an all-brass 1/24th scale dirt track stock car from scratch, and actually got a lot of the chassis done, but I think my new wife was going to have me committed to the loony bin with what I was going through to do it! What got done is still hanging on a nail out in the shop to remind me how close I came to insanity!

 

Awesome work Ray!

The coal is there to hide the nasty looking solder spots on the inside.

 

SAM_0396_zpsxmqo4jmp.jpg

 

 

I changed the looks of the coal load a little.

This coal load was off a larger tender from a plastic 0-8-0 locomotive model kit that was available back in the 70's.

It had a flat piece that angled up from the back of the coal bunker on the larger tender but this smaller tender didn't have that extra piece of metal sticking up at the back.

 

So I cut that part off the coal load and rounded the back of it so it fits below the back side of the coal bunker.

Doing this left a smooth rounded area at the back of the coal load so I took my soldering gun and kept poking the hot tip into the plastic to rough it up so it looks like coal.
