Worked on some additional motors. Built a low profile (low as I could get it) drive without bearings. This should fit underneath without being exposed to view.

So before anyone laughs over my wood (red oak) frame, let me remind you that Morgan made at least one road going car with a wood frame. Second I am hoping to build this one as scale like as possible, the Tamiya truck chassis is wider than this one. Before chopping up some aluminum or brass I thought I'd mock up this one to see if I can pull this off. The white card is to show the base of the soft cab. The armored cab is the same width up at the "cheeks" (just below the windows), the length are the same for each. That steering box skid plate is now installed on the reference kit. The wood dowels represent the chain driven axles.

I think you could have got away with using a Tamiya chassis.

You could just cut down the cross pieces surely?

Best of luck!

Oh yes that was a consideration. The Tamiya frame rail (C channel) is taller and narrower than my scaled up wood frame. I got it as close as I could with a table saw (a machine that scares the life out of me). Height is really close but the width is .020 (.52mm) fat. Again this is the mock up, the frame will be made from aluminum or possibly brass.

Close enough - nobody is going to measure it ;)

But I understand your want for scale accuracy.

And they still do! Ash frames on all of their cars (Morgan +4,+8, 4/4, Super etc etc.) including the 3-wheelers. Legit material for anything you want lightweight (relative term when you're moving planks of it into the wife's woodshop), and strong.

I'll have to admit I got that info from Top Gear UK (the only one to watch) and I was hoping the info was true.

The rear drive axle used on the M26 was a top loader like the Rockwell 5 ton axles and some used on Mack trucks, like this:

Monsieur Tox had asked about the driveshaft interfering with the axle tubes in the suspension travel. We'll be using Tamiya semi trailer axles but wider than usual. A CV joint will cure the angle problem if needed.

Looking great Eric.
Nice wooden proto!

And nice use of the BB launchers for the winches, I have a few that I'll be able to use!

You're right to be affraid of the table saw, that's the best way to be careful. When you're too confident using it, this is when something bad happens. My chief modelmaker lost a finger this way.

Yeah, my father worked with wood quite a bit and he had a healthy fear of those big toothed powered saws (I learned it from him). About 15 years ago while doing a house project for the wife I got lax for a moment in concentration. Turned the tip of my middle finger on my left hand into hamburger. Told the kids to bring me the first aid kit and "Don't tell your mother", needless to say but the wife brought me the kit. Finger healed but I still have a numbness in the tip of that finger to this day.

Ecam, were those "top loading" axles to allow for more clearance and reduced driveshaft angle? Just a guess...
