Even a misplaced Okie.  Very clearly done, I think even I could follow those instructions!  Thank you from MN, too.

Very good show and tell!!

When I wrap the leadouts at the wingtip, I use RED heat shrink on the UP line and BLACK on the DOWN line.

Cheers,

Those are the exact photos I go by since you first showed them in 04 (first that I saw). Great stuff then and now.

Is this really all that holds it? Just one wind down and one wind back, twist together, (do we twist two copper ends or one copper and one leadout wire) turn the end over and cover with heat shrink? We don't even work some epoxy into the windings?

    Yes, that is all you need. You twist the ends of the copper wire together and trim. A smear of epoxy can be added but is not necessary, some people even advise against it. Never solder the conection.
     I have found that once the copper tube is bent with the wire inside, it is extreamly difficult to pull the wire back out. Remember, this is 1/16 in. copper tubing and there is little play between the .27 leadout wire and the tube walls. Slippage will not be a problem and very little strain will be placed on the bindings. Hope this clears that up.

Being lazy, I saved all the pics by just saving the .pdf file...then it's all in one place. 2.2mb, I think.  LL~

Regarding Rustler's question...copper wire and stainless cable really grab onto eachother. "Galling", I suppose. Try starting your binding, wrap about 3 or 4 times (tightly, now!) around the cable strands, and try to slide the wire down the loop to make it tighter to the eyelet. Just about can't be done! No epoxy, no solder for sure. Heat shrink tubing is perfect for the job.  :! Steve
