That old mirror problem
Posted: 03 Nov 2015, 23:10
I may have stumbled upon a solution to the "Repacement-Mirror-folding-in-at-speed" problem.
Bought a new mirror last year. It folded in at 50mph.
Didn't have an OEM spring, so..........
Tightened it up. It folded in at 51mph.
Roughed up its balls. It folded in at 60mph.
Put a rubber washer in the joint. That cured it until I'd adjusted it a few times. Then it folded in at 50mph.
Put sand in the joint. OK for a while, then folded in at random speeds.
What I needed was something VERY tacky. I scraped some larch resin off the timber cladding of my barn, and smeared it on the ball. It has not moved a mm since, even at 70mph with additional truck blast. It is still adjustable.
I know everyone has their own favourite solution, but I hope this helps someone.
