Get a Good Reflective Surface for DIY Curved Mirror

[Shawnzyoo]

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

Reflective mylar film or aluminum foil and some spray on contact cement?

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)

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