Assembling

In order to get proper matching set you should:

insert pins in your best backplate (straightest)
press bushings in the shuttle and ensure a smooth mating between the parts.
if everything feels smooth, pop the bushings out and glue them in place using either superglue or epoxy.
be sure to test that the mating still feels smooth after the glue sets.
You can now use the shuttle as a "master blank" for glueing the pins into all your backplates.
