I have a DIY Helmet mirror - an old spoke is attached to my helmet and a 1" circular flat mirror is attached to it. I have used this with success for several months but would appreciate any helpful suggestions as to how I can reduce the mirror vibration

shorten the spoke, and attach it to your helmet more securely

A spoke seems awfully thin for the job. You'll need something thicker -- maybe heavy-duty coat hanger? On the other hand, anything thick enough to resist vibration will end up requiring articulations on each end.

You need to lighten the mirror, stiffen the arm, and strengthen the attachment.

A metal spoke weighs too much particularly if it's stainless. An aluminum spoke would be better but best would be plastic, balsa wood, etc. You can get carbon fiber whiskers for kitemaking, etc (google)

For a mirror the best thing would be a very thin first surface mirror - next best would be a silvered plastic mirror. American science and surplus may be a place to start.

The blackburn helmet mirror vibrates too much, I find the third eye to be better. Haven't tried the take a look mirror.

Wouldn't it be A LOT easier just to buy one?

Well, is the vibration due to the 'arm' of the mirror vibrating, or is your helmet jostling around a bit as well? My suspicion is that it is the latter. In that case, make sure your straps are tighter AND that your shock pads (i don't have anyshock pads, I glued in some strips of sponge) are absorbing some of the jitters.

Try and coordinate the rattle in your eyes with the rattle in the mirror! :)

All helmets move a bit on me when riding over, say, railroad tracks. The motion of a helmet mirror from rough pavement annoyed me enough that I switched to an eyeglass-mounted mirror.

new helmet mirrors cost +/-$15. buy one!
adjust tension as needed.
adjust view on each ride.....add velcro for multi-helmet use options!
spin safe!
