Well the time has come for serious thinking (some would say I should have done this before).
The North Yard gearbox I got from Branchlines runs very smoothly, and sticking a mini-drill on the back turns the wheels quite nicely! However this isn't exactly the most prototypical drive so I need to work out how to get a universal joint through to the tender and mount a motor.
First problem is that the shaft of the gearbox comes out only slightly below the cab floor. I think I'm going to have to live with cutting a slot in the floor and putting a thin piece of plasticard in as a new floor. Second problem is the height of the tender floor. Basically if I sit the motor on the floor of the tender the universal joint is going to have a hell of an angle down between the height of the motor shaft and the input to the gearbox.
As I'm not too impressed with the tender chassis I'm tempted to rebuild it. I could make the frames wide enough apart to fit the motor between the frames and have the drive shaft in the same horizontal plane as the gearbox input.
I've knocked up a quick turbocad drawing to show the problem.
Any ideas anyone?
