I have a similar problem as mentioned in an earlier post. The nib the that
sticks up into the bore of my tailstock and keeps the barral from rotating is
all but worn away. Been considering how to tackle a repair. Been thinking of
cutting a notch in the front edge of the tailstock and brazing in a new nib to
fit the groove in the barrel. Any of you ever do this repair? I've always
wondered how the origional was made because the barrel could not be bore with
this nib in place and there is no sign that it is replaceable.
