A machine shop theat is very good with metals might have difficulties such as meeting dimensional tolerances working with composites. Then there is the question of how tight these tolerances are required to be and whether the dimensional measurement must be traceable to NIST or some other recognized organization. Making sure of what the customer requires should be the first step.
