I have read posts where hand plane users can tell a lot about how they're planing just by the quality of the shavings coming out. Is there a guide somewhere which elaborates on this? Just to clarify, if a shaving is curling up excessively, what does that tell you? If a shaving has parallel tear marks throughout it, what does that mean? If a shaving is thicker on one side than the other, it tells me that either the plane blade is favouring one side or I am pressing down hard on one side. Have seen where they can also tell if the plane blade needs honing, I usually decide that if I feel that the plane requires more effort to push through. Hope this makes sense.
