Planer problems
I have an older Porter Cable planer that I purchased a few years ago. I have only ever used it to flatten wood no wider than 3”. I am now trying to flatten a 12” cutting board and I cannot get it to flatten. I have it on a flat sled with shims, hot glue, etc. to get it stable and I constantly get a convexed top. Tried a different sled, same thing. The bottom of the board is convexed also, so it’s not like one side is concaved and the opposite is convexed. Is it the planer and is there something I can do to adjust it. I just find it strange.
