I'm working on jointing some boards. On the first couple 7 footers, I noticed more material being taken off the front of the boards with little to none being taken from the back. I'm worried that by the time I get the front and middle of the board planed down enough to where the whole board is flat I'll have a toothpick in the front. What is the best method to fix this? Can I start jointing a few inches in on the board instead of the front to change the angle a bit and take more material from the back end? Should I flip the board to joint the back first? I don't have a lot of extra boards so I was hoping someone had some ideas so that I don't waste these ones.
Note, I jointed a few 3.5' boards and those were fine so I'm pretty sure the machine is set up ok. I'm just having trouble with longer boards.
