Why is it so difficult to plane paint off of wood?
Am I crazy, or do other people have a hard time with this? I've been woodworking with mostly hand tools for the past two years, and I feel like I've gotten pretty comfortable with a hand plane. I have a sweetheart 62 that's well tuned with a sharp blade. It planes plain wood just fine, and I know how to take an aggressive cut for dimensioning vs a light cut for smoothing, but I have the hardest time planing away paint.
I have a bunch of painted soft maple panels that are leftover from a kitchen remodel that the previous owners of my house did. It's great lumber, but when I try to clean the paint off, my plane just wants to slide over the surface. I have to advance the blade really far to get it to do anything at all, and subsequently, the wood winds up tearing out like crazy. I also get a ton of paint dust. As a sanity check, I also tried with my block plane. Same trouble.
Is this normal?
