But what about the actual gearbox, the driveline ?
Well, I'm not 100% sure yet, here are a few variations, note, some of these are set out as an "exploded" type view, so you can see what's going on.
This is basically using a slotcar rear axle, driven by a ZipZap Monster Truck bevel gear
Secondly, I thought about using brass hex rod for an axle, see here...
I'd say it's quite efficient using this method actually.
Exploded view
And that's what I decided on, though, the brass hex rod, in place of the axle there, will be replaced with round rod, rather than hex, so it's alot smoother.
I have to wait for 2 days, until the LHS opens again, so I can get some brass rod, I need alot of supplies, as the frame will also be brass. I need to make the gearbox carrier and more.
So stay tuned!
