I am looking to route a 1/4" static tube from behind the baggage bulkhead along the side to the instrument panel to add a standby altimeter. There are already two holes through the bulkheads, one under the armrest and one under the top longeron, along the sides with the pitot line and network wiring back to the ADHARS.
I am wondering am I better to enlarge one of the existing holes to accommodate the extra tubing, inserting a larger grommet, or is it better to drill another hole just big enough for the new tubing and grommet below an existing hole. I believe the best place to drill any holes in a structural member such as these is mid point between the edges, is my thinking correct.
I have searched past posts but most seem to develop into other discussions before a definite answer is revealed.
Any help would be appreciated. I have looked in the assembly manual and plans but cant find any direction there.
