I have fabricated a number of 1/8 and 3/16th inch thick busbars for an Van =
RV build electrical system which I am assembling in my shop. The busbars a=
re already bent to shape, but I'd like to anneal them, because the copper w=
as purchased in the "Half-Hard" state and making them "Dead-Soft" will ins=
ure that they lay completely flat to maximize the conductivity when I final=
assemble the system.
I usually anneal copper by getting it hot enough to glow with a propane tor=
ch and then allow it to cool. With the mass of these busbars, I can't get =
them up to a temperature to where they glow with propane. An Oxy/Acetylene=
torch would work, but I don't have one. MAPP gas is hotter, but I don't t=
hink it's a lot hotter.
I am considering running them through the cleaning cycle in the self-cleani=
ng over, as a self-cleaning oven will typically runs up to around 900=B0F. =
Copper needs 700-1,200=B0F to anneal, so it should be fine.
I'd prefer almost any other solution. Thoughts? The last time I used our =
oven for a shop project, it was to cure the paint on the jugs (cylinders) o=
f my '74 Norton motorcycle. Mrs. Jack was not happy. Copper bars should b=
e fine as they won't stink up the house.
Thanks in advance,
Jack
