I need a 1meter length of carbon rod of 14-16mm od, with a paired tube slightly smaller which can slide inside the id of the larger rod to form a snug fit as part of a wing joiner for a model plane.
If I buy say a 14mm woven finish tube, with ID of 12mm, will I be able to slide a 12mm OD pulltruded rod inside without much difficulty? How uniform and accurate are the inside of these rods?
