My dad had a Scout II when I was a kid. I thought it was pretty cool back
then. I've heard most of their rust problems stemmed from the insides of the
body panels not even being painted. Very durable trucks otherwise. I also
heard a story, an IH line worker said to a co-worker as he

I believe that was made not too far from my house in Fort Wayne, IN.
I almost bought one of those back in the late 70's.
They rusted like crazy in the midwest.

How hot does it get? Could you wrap the part in Kapton tape

Look up the Dollo 3D printer. All the files are free to download. It
includes pieces of herringbone rack and matching gears. Could have some
examples printed then make molds and cast in high strength resin. Could
also use the 3D files to 3D mill steel racks and gears.

If they are pre-loading to full contact, I fail to see the diff between
a spring load and a pre-load. With a spring, it might have enough give
to ride over a wood chip falling on the pinion.
The problem is that racks produce a significant force pushing the pinion
out of mesh. If I remember

That I like. And I'd not be surprised to find that the racks can be
butted together to get the effective lengths

Another option are master and slave pinion drives:

Tensioning the gear against the rack works reasonably well for plasma
cutters as they are lightly loaded. One problem is that gears generate a
force that is trying to push them apart. If I remember correctly the
generated force is about a third of the linear thrust. You end up having
to use a

I rather like the Servobelt idea. It should be much stiffer than a

For my future project (cnc router) I will have to use helical rack and pinion
system on two longer axis (2 and 3.5m). There are some designs where pinion is
forced against rack with spring tensioner, on the other side, if I follow
Atlanta's installation manual for their system, they forbid
