Could it be that one of my tail blade grips was loosening up causing the tail to be out of balance causing the bobbing?
You may be on to something there. I've had the screw that goes through the grip into the hub back out partway, ane that would definitely throw the tail balance off. Seems like it would be a high frequency jitter instead of a "bob", but it may be hitting a resonant frequency with the main rotor that causes a larger oscillation.

Throw that HBFP shaft and gear on there! You'll need to trim the swash rotation bracket and get new/shorten current cyclic pushrod links.
