I used the Weaver drive from my RS3 to power my 3D printed Seaboard Air Line motorcar #2028.
As a result, I had to make a new, longer drive shaft, over 7.5" long between couplings:
The front truck axle has the traction tires on it, I'm not sure they came this way or if they have been moved from the truck with the chain drive on it or not.
So I'm trying to cut down on noise/chatter and want to remove the drive shaft, and relocate the traction tired axle to the rear truck where the chain is. Can it be just an easy swap of one axle for another, or is there more to it I don't see?
I feel the long drive shaft is the root of the noise I'm hearing, I was going to put a pillow block midway but it would have to be slotted from side to side to go around curves.
I had to put the truck with the chain on the rear due to space limitations in the front. I doubt the traction tires are doing much good on the front anyway, engine is fairly light (prolly should add some weight inside).
