well, gulf et al, i have found a sheet metal shop that is willing to do some cutting and bending on a small scale.
to keep things simple, i think i'll just go with a couple of pieces of metal, and cover them with aluminum tape.
plan: metal - bulb - bulb - bulb - metal (i tried to illustrate this better using /'s and \'s and |'s and the like but it wouldn't turn out. hopefully this is making sense).
if any of you care to comment as to what angles (maybe just a simple 45 degree?) would be perferred i'd be very grateful. thanks for any opinions.
