I'm getting slightly frustrated with myself. I'm starting my first project working with rough lumber (aromatic cedar) and my results from the jointer is mixed. It is this older 6" Boice-Crane 1400 that I inherited from my great grandfather and restored:

It has adjustable height infeed and outfeed tables, three straight knives. It does not have cams to adjust the corners of the infeed table. I followed this video to make sure my tables were coplanar.
They weren't at first... in fact, they were drastically, visibly off. I could actually raise end of the infeed table with my hand... so I took it all apart and back together again and it's much closer. It's not perfect and only varies between front to back and by about 5-6 thousandths. Not sure how to get it better without any cams to adjust the corners, outside of maybe shimming it.
I then followed instructions to set my blades. I used the Rocker magnetic jig and set a ruler on top once the blade was set and the ruler only moved about 1/4" when manually turning the head (checked each blade, multiple points along each blade.)
The results? I'm getting tapered boards across the width of it. If I keep at it with numerous passes, a 4/4 board might end up with about 3/4" on one side and 7/8" thickness on the other. Additionally, I'm getting little "snipes" every 1/4" or so across the entire length of the board. Before yesterday's rebuild of the planer, I was getting a horrible gouge in the entire width of the last inch or so (I believe snipe), but that seems to have gone away.
It might be my technique as I actually jointed some 8/4 boards early on and thought they came out pretty well. But those were literally the first boards I ever jointed so I might not have known better. I'm taking really light passes and using two push pads. I'm pushing the board across with constant pressure and speed and adjust my pressure to be on the outfeed table once the board makes it over there. Brand new knives.
Any hints, tips?
