I've been doing reading about hand planes. Trying to figure out where to start. One thing that I just dont get... I can't see how you get a board or wood completely flat with a hand plane. You have a 2 inch or so slot on the bottom of a flat piece of metal or wood with a sharp knife extending out of it. To me that seems that it would always cut a groove the width of the blade into the wood? I know that I'm wrong, because people have been doing it for a long time... I just can't see how it works. Is there an explanation for this that someone can post? Or is it more of a 'just buy one and figure it out' kinda thing?
I guess I had imagined it such that if you ran a correctly calibrated plane across a completely flat board it would do nothing... but after actually holding a plane or two at a show this past weekend I dont think that anymore. There's a blade sticking out of it... one touch on your perfectly flat board and it's back to the carving board to start all over again.
Any explanation would be appreciated.
Thanks Mike W.
