I promised y'all I'd share when I started building these trucks, so, here we go....
Well, after scouring the internet and about 40 issues of Model Railroader Magazine looking for good refs, I started the power trucks for the Railtank Project. Here's what I'm building.
Using an N-Scale GP 20, I took 1/160 measurements and roughed out a plan on paper using a 1/35 ruler. Then, using .125 X .250 and .125 X .080 strip stock, I roughed out the general shape of the main steel components of the truck.
I cut apart the modern freight truck I'm using for the wheels and journals and using the cut-off journals, glued the truck frames to accept them.
Once I had the right general shape, I took the two sides and taped them together and started cutting and shaping by chucking a Dremel drum sander into my drill press and raising the table up.
So, here we have the final shape of the two sides and the journal/races dryfitted in. I still need to make final measurements to make sure the axles are the right distance from the top of the truck frame.
More tomorrow, any comments, or, praytell, criticisms welcome.
