I concur. Never ever machine (removing material) a bolt that is used hold on the wings. (Except small holes for cotter pins.) You will be compromising the bolts strength and corrosion resistance. Plating is also not a good way to go as the plating process can adversly affect the chemical makeup of the bolts. Thus affecting their ability to do the job. I attended a seminar dealt with the American Fasteners Safety Act a couple years ago and these are some of the things they addressed. The AFSA was, in part, a result of the plane crash in Chicago back in the late 70's. The one where the engine fell off during take off, (Flt 191, as I recall.) rolled over and crashed. As for the best way to handle this situation...I think the BEST solution would be to replace any worn parts. If that's not possible the next best thing would be to ream the hole to the next size up. I'd be afraid that bushing (Unless they are hardened) or sheet metal wraps would only be a short term solution. Mike Dean -----Original Message----- Sounds to me like there are some worn out parts there that need replaced. I don't think chroming or machining bolts is the answer! I think there is 0 chance that machining is a good idea (corrosion protection, hardening?) and I would be doubtful about chroming them. Messing with bolts in that fashion should be on everybody's list of bad ideas. Perhaps drilling and bushing the hole (with a very thin-wall bushing!) - but how would you determine if that's okay? You could maybe wrap the bolt in a very thin piece of sheet metal. I would not get caught anywhere near such a scheme (and I doubt the FAA will) and when even I am that way, you know it's a bad idea! __________________________________________________ To unsubscribe from this list please send mailto:[EMAIL PROTECTED] ___________________________________________________________ T O P I C A http://www.topica.com/t/17 Newsletters, Tips and Discussions on Your Favorite Topics . __________________________________________________ To unsubscribe from this list please send mailto:[EMAIL PROTECTED] ___________________________________________________________ T O P I C A http://www.topica.com/t/17 Newsletters, Tips and Discussions on Your Favorite Topics
