I have been working on my hand tool skills lately,
especially bench planes and my question is, "when increasing the
cutter depth on say a #4 or #7 must the cap iron pressure be released
before turning the adjustment knob, or can the plane iron still move
with the cap iron in place and tensioned?
Up till now I always would release the cap iron lever. What
is the proper way? Thank you for helping a wannabie knuckledragger?
