Is it all CNC, or could I turn them on a lathe myself with enough patience?

are there any guides out there? I'm taking a machine manufacturing class and would LOVE to rib my ironhead forks while I'm in there

No guides that I know of. Once you become proficient on the lathe, you'll understand how to do it. Look at a few examples to get ideas. Just remember to give serious consideration to the depth of of the ribs. Your life depends on it.

Good point.

What's the thinnest anyone should go when shaving lowers?

There are several threads about this here on Chop Cult...
Even one using acid to etch the ribs!
