I was milling down some 4/4 maple to 1/2 and ended up with some bowing in the wood after planing. I am a novice so I'm trying to troubleshoot where I went wrong with my process. The maple has been in my garage/shop for a couple of months now though hasn't been touched until today. I started by rough cutting the maple to 26" and then ran it through the jointer which only needed a few passes to get a flat face and square edge. I then ran it a bunch through the Dewalt lunchbox planer to get it to final size and unfortunately only noticed the bowing at the end.
In doing some reading after the fact it sounds like planing so quickly after jointing could be contributing to the bowing. I also removed the majority of the material from one side of the board which also sounds like a mistake. I'm also wondering if taking 50% of the wood off could be another factor. Thoughts?
