I thought it would be nice to post some still pictures of the current state of #5. In this view the engine is on a piece of 18"R curve so you can see the clearance between the engine and tender.


And here's a shot from the Fireman's side;


And an overview with the runnnng boards and a cab from an O.T. Bachmann 4-4-0.


Next is to bring #7 (the 3MM model) to this level.

Then I'll wire both.

Here's both engines mechanically complete with #7 in front.



Now it time to start on the wiring and electronics.

Checking in Bob.

Looks like great progress is being made on both engines.

A comment about that drive train. I take it you haven't had the chance to run the engines yet as you said wiring is next. I noticed that the drive shafts are at an angle from the motor to the gear box. I'm wondering if that will cause some vibration on an 18 radius curve. It'll sure be interesting.

Inch by inch, it's a cinch.

I hope they perform for you as good as they're going to look!

Thank you, guys.
They haven't been tested on track but I hooked them up to DC with some alligator clips and as the above video (on page 4) shows they run well. I didn't video it but, i did test it to see how this set-up handled not only horizontal plane curves but z-plane curves you get from sloppy vertical transitions and they seem to do well.

I would of preferred a more level drive staff but had to settle because the available gearboxs were too high or too low. These at least allow me to add some weight.

Got some done.
Here's how I added all wheel pick up to the tender;


Then it was time to add the converter.

Something I'm curious about, seeing the pricing for online metal printing services, how is the monetary cost of this project compared to an already-built brass locomotive?

If it's being built today it's about the same. Counting just the cost of the final prints it's about $500. per engine.

Sounds good!

Is that little black box on the tender the speaker?
