The use of a timing belt for a rack is a very clever idea
Timing belts do not stretch to the extent that would make any difference (as long as they were secured nice and tight)

The timing belts are for a reduction between the stepper motor and the pinion that will ride on a conventional metal rack. Thought about using timing belt instead of a rack but decided to go with metal.
The jig was made to drill the holes accurately in the material I will cut the rack from. another jig for the shaper will use dowels in those holes to position the material while I cut the teeth.
The jig will also hold the metal for the rails while I mill a 90 degree face for the wheels to run on.
