Assembling the bits

So, as with all good bush tram loco builds, we peruse the pages of Japanese N scale spare parts. The key is to identify possible candidates and then eliminate them. Whatever is left winds up in the shopping cart.

So looking at the target.....

We have a 0-4-0 but with the geared drive is actually an 0-6-0. Theres no real space for a motor in the loco so it will have to be in the tender. Now I'm not a fan (that's a bit of an understatement) of tender drive, so that's out. I prefer a motor in the tender driving a shaft through the cab to a worm drive. Pick up on all wheels is a must for any small loco. Oh and we need inside bearings as well (and outside power pickup is surprisingly common).
The big plus is that I don't have a scale plan so theres a bit of flex in my choices and I don't think anyone can tell me I'm wrong.
Well, you could but you would then be told where to go (and its not close by...)
So, after a bit of a hunt we get the following collection.


The "loco" end is from some weird ass Japanese Co-Bo shunter. However its got inside frames which passes the main qualification. A closer look reveals some very small holes which look like being ideal guides for drilling out holes for the crank pins. It also has a traction tire which is fitted for the express purpose of reducing the number of wheel available for electricity pick up, and to make one wheel a different size.
The bogie for the tender could be any one of the multitude offered as spares, so I just picked one that looked like it had inside bearings. The worm drive was picked at random based on the assumption that they are all the same (the gubbins seem to be common regardless of the manufacturer from what I've seen). In this case I was right.
And the wheels are finer scale replacements for Kato steam loco's and limited to 1 per household. I have no idea why, but possibly so that some modeler doesn't corner the market on replacement spoked wheels. I purchased 2 of everything assuming that I would screw something up somewhere along the line.
Motors are mini motors from Nigel Lawton. I've had 2 of these for a long time and it seems to be the ideal project to use them on. Oh and DCC is a given....
