Bronze sail track on an aluminum mast

[twhite]

Hi Brian,

For those that are listening in, a screw has to have a certain amount of thread to hold. I think the figure is about 2 times the diameter of the screw. So, a 1/4 inch bolt should have about a half-inch of threads. So I have not yet screwed anything into a mast. If you do have to, a bunch of small screws are better than a few larger ones. The Riv-nut option is a good one also, but whatever you do don't get the Chinese ones They strip out while you're putting them in.

Thanks again, Tom

There are various bits of bronze hardware on Mimi Rose's painted aluminum mast. Nothing as sizable as a bronze track, mind you. Still with an insulating layer of roofing rubber, SS fasteners, and TefGel, there's no problems after 21 years...
