I am just now getting serious about woodworking and buying new tools and material for my garage wood shop with each paycheck. I have a bench I made crudely for my shed a few years ago, and now am planning to make a decent size and decent quality work bench. I have a plan and will be using 4x4's, 2x6's, plywood and hardboard. Unfortunately I'm kind of limited to wood selection to whatever HD and lowes carries and my budget. Any suggestion on the type of wood I should use? Most of the stuff in those sizes are cedar, southern yellow pine and white wood. Any suggestions on which I should go with?
