nachoman 2021 do something clallenge, part 3

[nachoman]

Well, the first challenge is about done, less paint and a few details.   

My second challenge will happen as it happens, and is just to encourage me to get out more.

So... how about a third challenge 

I mentioned this in the Hobo Camp Fire a while ago.  I have a MDC Harriman 2-8-0 kit from 20+ years ago that I never truly put together.  The superstructure is done, save a number plate. It runs, but doesn't do well on sharp curves due to the one-piece side rods.  Plus, right now I am using an old open frame motor.  At one time I bought an expensive can motor and flywheel that I thought would fit, then I thought would not fit, and now think I can make it fit.  And my tender is still a coal tender.  

My goals here:
1) Make segmented side rods so that it can negotiate 18" radius curves without slowing down.
2) Add an oil bunker to the tender.
3) Find a way to adapt the new motor and install it.
4) Any remaining details and painting.

Step one was to design an oil bunker and send it to be 3d printed.  I went this route because in the future I will probably want to convert more tenders..
