The jaw for the front vise needed to be 10" long - to span the distance from the leg to the end of the top, 1-1/2" thick - to allow for benchdog holes to be drilled in it, and 5" tall. The end vise was mounted 3/4" lower than the front vise, and the screw and guide rods were thicker, so its jaws needed to be at least 6-1/2" tall. Again, they needed to be 1-1/2" thick to allow for benchdog holes, and 23" long to span the width of the bench.
My advice? Don't do this. If you have jointer and a planer, use them. If you don't, seriously consider using dimensional lumber that has already been planed and sanded. If you are going to try to clean up construction lumber by hand, using a hand plane is a lot faster and more pleasant than using a belt sander. Except, of course, that to do a good job of planing a board you need a solid bench to hold the board, and you don't have a bench, yet.
Post Woodworking’s Hampton shed is a major standout in design. The sleek farmers porch immediately draws the eye into its pure New England charm and provides the utility of shade and a cool place to sit and enjoy a cold one. Like all of our sheds, the six-panel doors which add to the structure’s aesthetic come standard. They’re made out of fiberglass to last through many decades out in the elements.
