[TenTec] 509 PTO how hard to rebuild is it?

No sorry I did not mean to be unclear about the PTO.  You have a mechanical
bearing that causes the tuning to be "stiffer" than a capacitor tuned VFO.
The core may not be threaded, but it is a shaft tuned mass that just does
not spin like a weighted dial on a cap, that is all I meant.  Even with new
grease, my Scout for example, requires much more effort to tune the entire
rotation than the new Argonaut V with its optical encoder tuning, or older
radios with capacitor tuning.
