Anyone able to direct me towards info regarding optimizing table tightness for higher speed performance?
I'm certain I'm just missing a thread here somewhere.

Shifting into higher gear, meaning swapping .25 for .375 compression bits with higher speeds and feed rates associated with doing so.
I already "over tighten" pinions, as I use a grip clamp to pull motors snug as I torque motor fasteners. Current set only a few months old. Cursory check shows nothing loose, decent hold down vac, but I do have some slight irregularity in straight edges, especially short distances, like 8>".
