RFGuy. Sorry to see you go. I have always valued you opinion on this forum. I will miss your content. My previous jointer was a small bench top jointer by Delta. I think it's even shorter than the SM Joiner but it will do 6" material. I surfaced the top and bottom of my material with a planer and then joined the edge to put against the fence. In talking with a fellow woodworker friend of mine he reminded me the batch of wood from this mill has had a lot of prestress in it. He purchased wood from the same lot I did and he was having issues with it pinching and binding in his saw. He suggests it's moving on me and it's not my saw. I'm beginning to agree with him.
Kevin,
Thanks. I appreciate it. Yeah, only two things can cause this issue that I know of. Either improper milling (usually not properly jointed and planed) or internal stress released during/after sawing. IF you have a short bed jointer (like a benchtop unit or the Shopsmith 4" jointer) you might want to make infeed/outfeed extensions for it, or buy a jointer with a longer bed. Otherwise you will simply be following the curvature of the wood and NOT removing it. Glad you got it figured out.

I would first examine my jointed edge against a known straight edge. Looking for that awful thing known as snipe.
If that edge is good, with the saw off, I would push against my guides, table, blade, spindle, etc to look for movement or deflection , there shouldn't be any.
Make sure you are using featherboards to help keep the stock against the fence.
Make sure you have good support for those long, kinda heavy boards behind the blade.
When cutting, do you hear a noticeable change in blade speed like the blade is slowing down a lot?
