Recently while feeding a board through my planer, I've noticed that the wood just stops moving, or seems to get stuck. I'd give it a nudge and it would continue moving just fine. Lately, it has gotten so bad that it takes a lot of hard pushing just to feed the board through. I am not planing excessively wide or thick boards, nor am I taking off more than around 1/16th of an inch at a time. My first thought was that the rollers weren't turning at all, so I turned on the planer and checked (without feeding wood through) and they seem to be turning fine. Has anyone else had this problem???
