Is the tubing 1/16 od annealed copper? Oh yeah, where is the best place to buy annealed 1/6 od thru 1/8 od copper at a reasonable price?

HI Ray,

I always heat the brass tubing with a little butane torch I got from Radio Shack.  Always worked fine for me. ;D  Never used the 1/16th copper.  And the 1/8th" O.D. K&S copper bends real easy once I put the Weed Eater line inside it..  I heat the brass to use for fuel filler/vents on built ups and use the Weed Eater line to keep it from kinking.

I  just run the leadout wire through 1/16 brass tubing and then wrap it around a suitable sized drill bit, feed it through the bellcrank and then close up the ends and wrap about 1 inch of the leadout pair with copper wire. This avoids softening the brass tubing.

I have a pictoral on here called, "Leadouts My Way".   Do a search for "leadouts".  I use the swagging method of doing the ends, but wrapping with copper wire can be done as the tubing holds the cable in place better.
