So .002" to .003" should be fine.
I suggest so.
And be sure to slightly taper the ends of the bearings themselves, so they do not wipe the oil off the guide bars as they move.
It will then "cam" the oil between the surfaces, giving better lubrication.

Hmmm...
I made mine with very little "slop" when cold. They have not yet seized up when running.
But I don't have any specific numbers to give you. It was all by feel.

Having chosen and managed a 48" x 48" water jet cutter for the Univ. of Washington ME shops, I can attest to: - The usefulness of these machines, - The challenges of getting them operating correctly and consistently, - And the operating expenses incurred. Not inexpensive. A small shop unit...

Case in point I bought roller/shear/bender for doing the boiler sheet metal and I have used it 3 times for other projects and not even close to doing the boiler skin.
Good work getting the crosshead guides squared up.
That will go a long way toward guaranteeing good operation. More work up front, far less work downstream.
You'll be happy.

Dial calipers are notorious for getting crud in the rack and pinion, causing inaccuracies.
Or worse: A skipped gear tooth. I've corrected my share of those.
