Quick update. I pulled a muscle in my back putting some shelving in a new closet so I haven't been in the shop in a few days. This morning I decided to check the jointer setup once again. It turned out right but I had a "Duh!" moment that, somewhat embarrassing, I want to share. I knew the infeed and outfeed tables were coplanar. I checked it multiple times with every straightedge that I have in the shop. The last thing was the blade height. I had eyeballed it by laying a an engineers square on the outfeed table and turning the blades. They just touched it but that was eyeball. Then I began to wonder if there was some way I could use my Digiline gage to check it. I bought it for my table saw and that's all l used it for. I looked at the directions that came with it and it was all about table saws. As I turned the box around, there was a picture of how to set it up to check jointer blades. After my headache passed from slapping my forehead with the palm of my hand I decided to try it. Although the tip of the gage is round, a flat one would work better, I was able to check each knife at both ends and in the center. They were all within .002 so I figure that's close enough. Hopefully, in the next day or two my back will permit me to cut up some lumber and run it through the jointer taking note of how i'm putting pressure on the piece as it moves across the cutter head.
I guess my take away from this is to "think outside the box" since that's where the picture was
