Aileron pushrods - reaming the bushes


The teflon bushes are built into the wing. They start out with a 19mm hole into which the pushrod fits snugly. If left like this there is too much friction in the system. To eliminate most of the friction one can ream the bushes "in situ". Various reaming devices work but the most successful so far seems to be a step drill. (Thanks Kelvin!)
