3/16

deeper
than originals). Thus the top and the bottom of the new hole =

fresh cast iron. Needed the drill press because =
the
original pins were harder than surrounding cast iron - couldn't push the =
drill
in by hand. See photo. New pins will be 3/16 x =
1", with
7/16" exposed. If I set the height of the new bass bridge cap
correctly, the loops will rest about 1/8 above the plate. =
