Brent and I were having a short discussion about rust, and I made a little
sketch of a fastener set-up I'll be using in a particular area that should help
reduce the expected corrosion, and aid in maintenance. So I thought I'd post it
under a new subject line. Anyway, the reason for this particular set-up is that
the fairing mounts are tucked into an area that will be impossible to reach from
both sides, so the stainless nuts are welded onto the tabs, and the nylon
bushing will give me the ability to cut off the head on the brass bolt if it
gets corroded/stuck. Because the brass bolt is soft, I will be able to drill it
out easily without destroying the stainless nuts. The fairing is made of 3/8
fiberglass, and the nylon bushing will help protect it from minor bumps, while
keeping corrosion of the brass bolt to a minimum.
I have several different places where I'll be using nylon washers and
bushings. The washers and bushings will be carried as spares for field
maintenance in remote locations.
Here's the sketch.....
I'd be very interested in any comments you guys may have, and would
love to see/hear of any other ideas on how to prevent corrosion on our subs.
