What size hand plane do I need?
My personal recommendation for a first hand plane is a number 4 or 4-1⁄2 because with a smaller sole it can take shavings readily almost anywhere on a board. If it comes time to joint a long surface, place a straightedge on the surface of the board. The straightedge will show where the highspots are on the board.
