I only need a piece of about 4 inches long by about 1 inch wide and half an inch thick.
I'm getting the hang of this "inches" thing huh? Who needs millimetres after all?

Yeah, so I only need a little bit. Not sure what it's worth but someone make me an offer if they have a slice lying about.

Just take some copper tubing, smash it flat, add another for desired thickness and drill the holes.

Wala....a bus bar.

I just made two that way, for my 2 solenoids, that cut off the NEG bat power.

I ran 2, $10.00, 48 volt solenoids in parallel, rather that spend $116. on a contactor.

Works great.

I've heard of that method but it sounds... kinda... unique looking.
You don't have a picture of how it turned out? It'll be going into my main control box which I really want to keep pretty.

[Coley]

I will send you a picture tomorrow.

The thing about copper tubing is that it's not very high quality copper. It can end up making for a somewhat high resistance connection. And half an inch thick? I think that might be a little overboard...

There's a chance that a company that does ductwork and that kind of thing might have some copper. You should be able to obtain it locally.

Gav, did you get the email with the pics of my "buss bars"?

[KiwiEV]

Hi Coley, no sorry. I think my spam guard must have pushed it away.
Not to worry, a mate in Auckland has whipped up a busbar for me out of some chunky copper plate. Looks nice now! I'll post a picture tonight.

Gav - your second one (52.5mm) is on it's way to you now...

[KiwiEV]

Nick! Your a legend!

Kiwi, what size wires are you using for the pack and motor? I bet you guys are still using circular mills over there instead of gauge aren't you!

Anyway, your bus bar of 1/2 x 1" is capable of continuous current of probably near 1000Amps! Of course you'll have very little voltage drop across that sucker!
