Just a thought, but: could the problem actually be the wood, not the scraper
plane? If it is almost but not perfectly flat (if, say, it had been smoothed a
bit with a card scraper), then it might take whisper bits on one part of a pass
and thick chunks on another. Have you tried it on different pieces of wood? Just
wondering, I have no experience with scraper planes.
