operation done properly solder between steel music wire brass coupler will hold Never trust solder contact alone hold Before applying solder use rile make several small notches music wire soldering will occur notches will take load Also use solder ing paste plenty heat soldering Failure use soldering paste can prevent solder bonding procedure also applies solder ing landing gear wires notches landing gear wire should placed soldering area wrapped 040-in-diameter bare copper wire Again use soldering paste ample heat necessary follow procedures ordinary solder can used soldering paste
