I found copper flashing material (valleys on house roofs, etc), at the =
local hardware or Lowe's. It was about 0.10" thick and kinda soft so it =
was easy to make a buss from.

  Al,

  Your local ACE hardware store (or the equivalent) probably has a =
display from K&S Engineering of small brass & aluminum tubes, angles, =
and bars for hobby purposes.  Just the ticket!

    Thanks for info on buss material.  I thought there might be a =
corrosion issue on aluminum.  I know there is an issue of fatigue =
failure as well in wires, which wouldn't be in a buss.



    Aluminum is at least a good conductor; resistance about 1.6 times =
that of copper.  Brass, on the other hand, has resistance about 4 times =
that of copper.  The 1/8" x =BD" copper I had I got from Aeroelectric; I =
was surprised to find that he is now selling .025 thick brass instead.  =
In a =BD" width, that's equivalent to about a #15 wire.  Seems pretty =
marginal for a buss with half dozen or more circuits running off.  The =
copper was equal to about a #2 wire.  1/8" brass would be great - now =
where will I get that on Sunday. . . .=20



    Who's selling copper buss??  I have some .040 wall copper pipe =
laying around.  I could cut and flatten that. =BD" wide would be about a =
#7 wire. That would handle it.



    If you DO decide to go with Aluminum, how about sending the Copper =
to me.=20
    I promise I will give it a GOOD home .... Jim S.



    Sorry, Jim; no copper coming your way. I used most of what I had on =
ground busses.  Considered the  aluminum because I hate having to go =
show parts when I'm in the middle of a job.

    Al,



    Just the usual concerns with aluminum conductors.  A little light =
corrosion in an aluminum connection has a lot of resistance, whereas a =
little light corrosion on copper adds only slight resistance.  Extra =
resistance causes heat, which accelerates corrosion.  A vicious circle.  =
Therefore, you need to make extra certain you do what you can to prevent =
corrosion at the connections to an aluminum buss.  Special coatings, =
etc.  On balance, I don't think it's worth it - I'd get some more =
copper!
