I remember some discussion in the past on this issue but a search yielded no hits.
Nevertheless, I just purchased a set of Board Buddies for my Unisaw with Biesemeyer fence. I was hoping they would provide an extra hand when feeding panels of plywood by keeping it flat on the table, and not lifting into the blade.
Well now that I have them in hand, I doubt much leverage could be exerted with my fence design, as the rear is not secured to the table. So instead of the wood lifting the entire fence would lift from the rear. Also I am concerned that the aluminum front guide rail would be dented from this movement.
I know I need a sliding table and outfeed support, but would appreciate any comments before I return my “buddies”.
