Runout???

[catamountsierra]

I can see that if the press itself twists, like my old aluminum Lee press did. I upgraded to a Rockchucker Supreme and haven't noticed the press bending under load. I don't measure runout, but it was weird feeling that old press bend... I think as long as the press doesn't bend, it should maintain its alignment even if the bench it was on flexes. Maybe someone with more experience can confirm that, but that was my experience and thoughts.

Do you guys think I could be introducing runout with a press mounted to a bench that isn't perfectly flat?
Maybe the press is twisted slightly..

Nope.
