[SEL] NC or NF thread

[Gene Waugh]

Curt, could you go into this a little deeper, or possibly send me to a site
that can explain this turnbuckle more for me??  I can _sorta_ see how the
two tpi could give a differential, but both with rh threads?--that is the
part I cannot visualize.  In Ron's example, the winds are opposite, which I
can see where it would provide a compound action.

TIA---and Thanks also for the pictures & write-up of your piston sequence!
