Re: Stripped out threads for key's flat spring screw?

Filling/redrilling stripped threaded screw holes can be done by hand using a bench motor, a drill bit from 1.7mm-2mm drilled into the key by around 2.5mm-3mm. Nickel silver or brass rod can then be made to fit into the hole with some very slight wobble or filed down to fit but left a bit rough so the solder will flow through the entire depth. Then once soldered in, the end of the rod is cut and filed flush with the underside of the key, then the rod is centre punched and redrilled with the appropriate size drill bit for the screw thread size you're planning to use (eg. a 1.1mm drill for a 12BA tap to take a 12BA flat spring screw).
