weird "threaded" tuning pin

[gordon stelter]

I flipped one of these over and put a LOT of
"Pin-Tite"(TM) on the pins from underneath. And I DO
mean a LOT!!! --3 bottles over a week. Just look
periodocally and keep filling up the holes. While
others gripe, deride, fume and digress regarding
"Pin-Tite"(TM) I have found this method quite
efficacious, even on a 6'2" Conover that had
"spinninpins". Made them rock solid and eminently
tunable!!!
    Though normally my preference, I did not use CA on
this Broadwood as I feared it would make solid caps
over the bottoms of the pins, which would then cause
the block to delaminate (if it has any) when the pins
were turned. I have also not used CA on highly
valuable instruments for fear that, if used in large
quantities, it would glue the plate to the block, lock
up the plate screws, etc., making future removal
difficult, at least.
