The yoke (not the tote) can be broken by trying to close the gap between the
yoke and blade depth adjusting screw via bending the Y portion of the yoke to
reduce slop. Patrick Leach (http://www.supertool.com ) says NOT to do this. I
have driven out the yoke mounting pin by pre-driling and the extracting (used up
4 drill bits, they kept snapping off). Given that one can purchase a #5 frog
for <$10 I would opt for that repair route. Its not worth the headache of
replacing the toke.
