Dave:
Your mods are amazing.
I think you have surpassed the original manufacturer's content and most of that saw is now 'yours.
I do not have a problem with loose pivot bushings, but you are right that any little bit gets magnified by the length of the head (and of course the flex in the frame doesn't help).? I think these deficiencies become tolerable because there is not much side force when cutting.
I recently found a YouTube video by 'Blondihacks' where she is really pushing the limits of a 4 x 6.
The result that she gets is quite good.? Apparently her saw cuts pretty square (looks like it is probably a JET).
I think you guys would enjoy it...
The relevant part is from 14:00 to 17:00 minutes if you want to jump right to the 4x6 section:
