I found a used jointer/planer and the owner has a feeder mounted to it right now. It looks like a nice thing to have...but it got me thinking. A feeder is going to put alot of downward pressure on the board correct? It seems to me, that removing a bow or cup in a board would not work, with the pressure of the feeder wheels. I'd like to know if I'm thinking this all wrong. I may offer to buy the feeder with the j/p if its a worthwhile add on.
