I am looking to make a medicine cabinet 4 foot wide by 30 inches tall
+or- and 6 inches deep outside measurements. I am planning on three
mirrors hinged in such a way as to be used for make-up or what ever.

I am planning to put a row of lights above and prettying it up with
molding.

My question is regarding the mirrors and hinging them. Frameless would
be nice, but I'd like to attach the glass in such a way as it would
never come loose or fall.

Currently the one I am looking at replacing had a mirror come off, and
somehow my handicapped kid caught it, or prevented the complete fall
onto a granite top. That was a couple years ago. Recently a daughter
in law was using that same bathroom and had a mirror at the other end
come loose, yet it caught her by surprise and it did hit the counter
and crack all over in multiple places. On inspection I saw that its
"hinges" cracked in two, both top and bottom and I can see that the
next one is not too far behind. So I am looking to replace the whole
thing. These mirrors had beveled edges and the glass and mirror shop
said I would have to order mirrors if I wanted beveled edges, and
there is no way to attach a beveled edge to a pivot or hinge that I
know off and to do so reliably.

Any thoughts, ideas, or links would be appreciated. I had thought
about a channel for the top and bottom for both the mirror and a glued
backing, but don't like the esthetic appeal or the problems of
cleaning the mirror, LOL, well my wife would be the one, but I'd like
to make it easy for here. I definitely would like the mirrors to open
like \_/ as the existing do.

Thanks for considering anything in this regard.
