Re: Chieftain Mk V scratch build

I got impatient and decided to get a jagdepanther set of Taigen metal gearboxes from Welshdragon and they arrived today. Needless to say I have done nothing else today but fiddle with the gearboxes and build the small platform in the rear of the chassis to accomodate the gearboxes at the right height. For those building the chassis, the platform needs to be 11mm above the chassis floor to get the sprocket to the correct height.
Having organised that I then found that my sprocket design needed to be modified to fit on the 58mm shaft in order to position the sprocket to line up with the wheels, so a swift bit of redesign of the sprocket, 150 minute print job later, and there we are.

Note the gearbox has to be right up against the chassis wall

and it was also necessary to cut a hole in my bracing piece to fit the gearbox almost up against the rear of the chassis

Now I just have to fasten the gearbox down and do the other side.
