I am building a GP Skybolt and I'm to the point where I need to solder the cabanes together. The question is this; the kit contains I think four short lengths of "silver wire" to wrap joints that require soldering. The problem is that none of them seem long enough for the job, so I used 2 lengths on the first joint thinking it would be easy to find more "silver wire". I can't find any "silver wire" but have found same guage galvanized steel wire, will this take and hold the acid core solder like the stuff in the kit? I would really hate for this joint to fail as it holds the top wing on...kinda crucial! Thanks sorry this is so long. Steve
