As i am in the US i have to do it all on the internet . Thank you in advance for any assistance .:-)436857475_1189185002094362_3724272207270546630_n.jpg.d288446d27871a3f17dad994076d6ad4.jpg

One of the disadvantages of buying through Shapeways is that you are very much on your own when finishing the build. You haven't given any other details as to scale, gauge or width between the frames. You will need to look at various suppliers such as High Level Models for motor and gears, Alan Gibson or Markits for wheels, crankpins, bearings and coupling rods.

 

Unless you can find someone who has already built a 3D version (there is a 4mm etched kit available for this loco but information on that won't help you), you will have to work out what will fit.

The High Level Kits website has downloadable profiles of all their gearboxes so you can hold them against a model or drawing and see what will fit. Remember to allow for the thickness of the material though. Given the distance involved I'd be inclined to make a small card mock up of your chosen motor/gearbox combination to make doubly sure it fits inside the body.

I suspect you'll need a slim gearbox to fit between the frames as they're thicker than normal etched brass. You'll also need bearings (hope the holes are right). Any small can motor will be fine for DCC and that chassis will prevent shorting issues. You could do with pickups on the leading wheels as well that appear to have some float otherwise track/wheel contact may be a problem. Some light springing may help.

 

Wizard Models might have suitable Markits wheels, otherwise Gibson. There are currently supply issues with Markits.

 

How's the surface finish on the body?
