You are going to have GREAT difficulty finding an inch-based
encoder. Teledyne-Gurley used to make them, in the 1960's!
All the encoders are now based on metric units, to my knowledge.
You might be able to find a VERY old Teledyne or other scale
that is direct reading in imperial units, but it will almost certainly
need repairs. Can the MicroKinetics software translate to inches
from metric screws? That would be about the same situation.
