How thick is the mirror you use? I haven't been able to locate any small sources as yet. Ridout Plastic has 2' x 4' x 1/8 sheets of mirrored polycarbonate, which sounds ideal, but goes for $190, which is kind of pricey for a one-off. Plexiglass is about a third the price, but that's still too much. They are local, so I emailed them to see if they have samples/cutoffs available. The plastic mirror material I use is about 0.075" thick. I used to use the steel wire that forms the handle on containers of Chinese take-out food; it had the right diameter and degree of hardness. The wire can't be dead soft, but it has to take a sharp 90 degree bend. I've now upgraded to 0.050" stainless steel wire. I got this plastic mirror material at a local surplus store, but my early ones (over 20 years ago) used a roughly 4" x 5" plastic mirror I found for sale among the camping supplies, with the cheap compasses, waterproof matches, packable toothbrushes etc. Let me know if you can't find the stuff. -- - Frank Krygowski |

I am using the Bike Peddler Take-A-Look mirror on my eyeglasses. Original longer stem length. They also offer a shorter stem length. I seem to be happy with the longer stem length but have never tried the shorter stem length. Anyone want to offer opinions and reasons for having a shorter or longer stem length on the mirror? |
