Tuning Tip Threads

[Joe And Penny Goss]

The shaft end is. Thus the female part of the head, not the tip.
There are two 1/8" pipe threads One tapered side the other straight.
Standard usage in piano hammers is the tapered thread. This thread over time can fail if the user does not notice the looseness, and tighten the conection.
This joint is also where most of the flex is in the tool.
My hammers use a straight thread and a mating platform at the head/shaft that reduces flex. Along with a 1/2" hex shaft making it a very responsive lever for the user to feel the movement of the tuning pin.

      Joe, aren't some levers and heads threaded to 1/8" pipe?
