Well, I stopped by home depot after I posted this and finally found galvanized 1/16" cable, which worked like a charm. I simply placed the cable into my helping hand at the point where I wanted the solder to stop and the alligator clip dissipated enough heat to stop the solder flow. I'll keep my eyes open for the staybrite stainless compatible solder though. This store didn't have it. Thanks for all the suggestions. Now, I've just got to route the antenna along the fuse and do a final balancing and preflight check. Hopefully, she flies next weekend.
