Is there some general rule that can be applied? How much torque can the various nut plates accept before cracking, deforming, stripping, etc? How much torque should be applied to the bolts holding various aluminum components in place such as the elevator hinges or elevator bellcrank bracket? When should Locktite be used? I noticed that the nut plates and lock nuts are deformed to pinch the bolt. Do the rules change when lock nuts or other locking mechanisms are employed? I've twisted off a few bolts and don't want to repeat the experience or the repairs. It appears some of these bolts are pretty soft compared to what my life experiene would suggest. Any insight on how I should approach the simple task of mating nut to bolt would be appreciated. And to answer your question - Yes I, a computer geek, do intend to build and fly a Lancair. :) Thank You
