[Boatanchors] Is there a better way ?

[Pete Williams]

It happens---when you have  a  tight tuning  slug/core in  a  coil   and
you break off  half of  the  screwdriver  slot on the  brass threaded
shaft. .  When it's  impossible to replace slug or cut  another slot ,my
solution  was to find a brass nut  that  fits or partially (preferably)
screws over the  damaged  shaft, heat up  the  soldering iron  and  quickly
apply  a  liberal dose of   solder into  the  hole.
I  figured  that sufficient  solder bonding to  the nut  and the  unbroken
side of the  brass  shaft  tuning slot, would   allow  sufficient torque
to allow  a spin tight to  move the  slug  without  damage----thus
preserving a  degree of equilibrium in the   workspace !
  Seems to  work  for me . Any better suggestion , apart  from  dismantling
the  offending  item  for possible   replacement?
