Thanks everyone. Lots of good suggestions here, really appreciate the quick response from everyone! I'm heading today to get some roller stands for both sides. As someone suggest can never have enough and I've really needed them in the past before, time to spend a few bucks on them.
My jointer has 54" beds & is tune pretty much perfectly. But if I edge joint a board that is in the 6'+ length, it will tend to take on a bit of a concave bow, like the OP's. I built simple extension tables about 30" long for both the in feed & out feed. Fixed the problem. The sections for my workbench top were 3.5" x 10" x 72" & they jointed perfectly for glue up.
