Reflective surfacing

  1. Jun 10, 2005 #1
    I am attempting to build a curved mirror from an old satellite dish.
    The problem lies in the fact i am not sure what to use to get a good reflective surface.
    any suggestions would be most appreciated.
    thanks

    holy undead thread batman!

    back in '92 I converted a 12 foot dish using 1 foot square mirror tiles

    by attaching the mirrors with two drywall screws at each corner the dish's curve produces a focal point roughly where the lnb was

    if memory serves there was room for 112 tiles w/o overlapping mirrors


    don't know what the exact concentration ratio was but it worked great for igniting wood, flash boiling water or melting lead

    (if you have access to scraps from a glass shop hexagonal or triangular tiles could provide better coverage with smaller gaps)


    *fiddlesticks, thought there were more pics but these were all I could find

    By "mirror" do you mean for visible light? For radar? For some other wavelength range?
