Interesting source for cheap bounce mirrors.
I drive by a tv repair place every day and see junked big screen tvs by the dumpster. I got to thinking, they use a mirror to reflect the light from the crt guns onto the display screen.
So I go in and ask if I can scrap the tv for the mirror inside. I even offer to dispose off the remains into the dumpster so they dont have to. the guys say sure, so i bust off the plastic front screen and inside is a pretty much pristine huge 2 foot by 3 foot front surface mirror . I pull the support frame and now I have a fairly robust mirror that can be cut down into several bounce mirrors.
Cheap way for hobbyists on a tight budget to get good front surface mirrors.
Will there be three phase!!!!
