Title: Brazing Questions
Post by: Chris on March 14, 2007, 11:13:19 PM: Im looking at using some metallic tubing to run wires in places on my car, I was thinking about brzing them into place. What I need to know is what type of material to use for the tubing and what type of brazing rods I will need to attach these to my car. The material needs to be soft enough that I can bend it somewhat easily to fit around the various contours of the car.

Essentially I am building conduits for wiring that is normally visible, I want to eliminate all the visible wiring I can.

Aluminum is going to be the easiest to bend, it can be attached with JB weld and faired with bondo, no heat = no warp.

If you really wanted to go the distance with it you could then get the ferrel fittings for the end. It would eliminate the sharp edges and give you a way to attach it to a bracket or something of the like on the ends. As far as brazing it to the vehicle I can't help. Sorry dude (the J B Weld trick sounds easy enough if it'll hold)

Keep in mind though that Copper is expensive and heavy when compared to Aluminum and both would buff/ polish up nicely.

if so...why bother? you're adding unwanted weight for no reason. allthough it wouldnt be much and i think that it would look kinda cool, when you're trying to cut 10ths of your et doesnt every lb count?

just my logic. ;)

Post by: Chris on March 19, 2007, 10:18:45 PM: well the copper and the jbweld idea was bunk

so im just going to source some material similar to that used for the hood release tube and tack it in place

well then, for looks i think some smaller diameter polished aluminum tubing would look good. i also think that rather than trying to permanantly attach it to the car (via brazing/welding), some well placed brackets or hold-downs would look clean.

just my $.02
