I like Lutz's suggestion of a NWSL gearbox, but would investigate the possibility of placing it on the third axle, with the motor in the boiler and facing to the rear. That should make the gearbox less noticeable.
If you decide on a tender mounted motor, you may be able put a larger flywheel in the boiler or firebox, between the tender/loco universal and the NWSL gearbox. At least the tender's frame and wheel set-up should eliminate the tender-body torque-flop often common with tender-mounted motors.

Thanks for the info Schraddel !

Thanks for all the help guys, I really appreciate it...My current plan is to ditch any effort in putting a motor within the boiler, it really is much too narrow for that and there is no meat to grind away to make it larger. However, I will put the motor and gearbox in the tender itself, the engine will just be there for the ride. I'll be able to fit a flywheel and motor I already have and only need to find a gearbox to fit the tender axle.

On another another, it boggles the mind that one can commit so much capitol, tool work and engineering and use only minimal grade materials and parts. Steel wheels...really?

What else I remember:
The motor. K's motor had 2 tags coming off the brushes. The top one was bent down to contact the motor body, the magnet pole I think. This was electrically soid with the frame and the axles. The bottom one was bent outward and twisted or turned and a piece of phosphor-bronze strip soldered through it and bent and sprung to bear on the back of the tires (or tyres) of the insulated drivers for pickup.
