Steve,

Since I'm thinking of modifying my drive system I made a sketch of what this
would look like in my case. My scanner is kaputt, so I'll try to explain how
it looks.
My drive wheel would need to be divided in 16 parts, because of the track
design (inner treads 120x30x5 mm, all 10 mm apart) combined with the drive
wheel diameter (180 mm or 7,08" + 4 mm rubber layer). The sketch shows that
the tops of the flats would need to be 2 mm above the drive wheel outer
diameter. I could use the existing wheels and use 2mm welding rods to create
the flats tops. The gaps could be filled with epoxy or some other material.

I am also rethinking your remark concerning the mounting of cleats engaging
the inner treads. I do like this option as it provides some sort of sprocket
drive, I am concerned however about the wear of the inner treads in the long
run. What I could do is only install 8 cleats divided over the drive wheel
diameter and change the drive wheel position on the tracks every once in a
while to divide the wear over all inner treads.

Will's remark about the fatal combination of chain drive and kiddies fingers
made me return to the friction drive setup again, just to be on the safe
side!

Just my 2 cents, thought I'd share it with all you guys.

By the way: if anyone's interested in a genuine Panzer IV in need of a
little TLC, check this out: http://www.milweb.net/webverts/13169/

The attached graphic illustrates an idea I've been kicking around.  It came
to me after looking over Amir's work at the Coxsackie event.  It's a TTS
friction drive wheel, still wrapped in thick rubber but the "enhancement"
(lets see how many spam filters block this one ;-) are the flats around the
perimeter.  The flats match the track width and spacing.  Think of it as a
half a friction drive and half a sprocket drive.  It would take more thought
and effort to make but it should provide better performance with less
tension than a round drive wheel setup.

Joe, what's your thoughts?
