What is more, the OP can also realise that nylon pinions are common on modern printers where they get much more use than on his intended camera...
Ultimately, the OP can also realise that other people's misadventure with Linhof cameras have no bearing on his own construction and go for the intended nylon rack and pinion modern material for his camera.
Petty pissing contests aside, I think that polymer rack/pinion options are viable for 4x5” with somewhat limited draw. That is, not loading the camera up with massive >270mm Fast Plasmats.
One suggestion I would offer that comes from my experience with building timber cameras is to avoid wood on wood sliding components. I feel that you’re going to get a smoother, longer lived camera if you have a Teflon (or carbon on carbon) weight bearing strip. These low friction options will take the stress from the gears to a great extent.
The flip side of this is that you’ll need a decent locking system to stop inadvertent movements once focused!

Hi Andrew,
Metal racks and pinions are available in a range of sizes from McMaster-Carr Supply Co.

If you believe you can, or you believe you can't... you're right.
A camera build by the very resourceful "barnacle" is worth looking at.

The source he provides on the first page also have brass racks and gears. Useful for members in Europe
Hope this helps.
