I never did thank for posting the, more specific info, about the carbon wing tubes that you put in place.

Still have not had the time to get into retro-fitting new tubes into my 310. Think my challenge is going to be getting the old tube out, and maintain tubing alignment.
- My plan is to make a drill bit out of tubing, that "just" fits over the current tube. Going to use the current tube as a pilot to bore all the way down into the wing.
I am hoping that this will minimize the need for a fixture, as those tubes are already running parallel ...
- will have to measure to make sure. might be able to "float" the tubes at the butt joint to take up minor (a few microns), then tied it down.
As mention, this plan is complete, and trying no to tear into too much.
