So, first off I've watched Bob's video on how to make rudder and planes linkages a bunch, but I know I'm doing something wrong. Either I have the wrong solder (likely) or I'm just not getting something right in the process.
I'm trying to make linkage horns for my 1/72 LA out of wheel collars and 1/16 brass rod bent to shape, but the problem I'm having is that even with the wheel collars roughed and filed so the nickel plating is gone and brass is shining through, when I put the solder to it and leave a bead on there... it falls off after it's cooled. I'd like to have something that's able to run and turn in time for Subfest, but this linkage conundrum is driving me batty.
I can only assume I have the wrong solder: I'm using stuff that allegedly is silver solder in a plumbing repair kit (solder wire and flux paste), and I'm using a butane torch for the heat. I have to assume that I need a different grade of solder.
That said, can you gents point me in the direction of the stuff you use when making linkages? OR point me in the direction of the 'easier' way out and guiding me towards nylon servo horns I can stick 5/32" wheel collars into?
