Design Basics
ОглавлениеI built this workbench to fit my 6'-tall body. The rule of thumb is to locate the worktop at half the height of the user (in this case, 353/8"). If you need to build it higher or lower, simply adjust the length of the legs (see the leg subassembly drawings on page 14).
The top of the bench features two parallel rows of bench dog holes. The front row is close to the edge, but the back row is set in a few inches to help support wide subassemblies such as drawers or cabinet doors. The top is large enough to clamp a standard 5'-long kitchen base cabinet, with a few inches left to set down tools or hardware.
Four Bench-Building Basics
1. If you regularly build furniture or cabinets, the space between the last bench dog and the wide-open vise jaw should accommodate a standard 5' base cabinet.
2. A good rule of thumb is to size your bench so that the top is half as tall as the primary user.
3. To ensure stability when lateral force is exerted on it, a bench should outweigh the user by about 50%.
4. One row of bench dog holes should be set in a few extra inches. This makes it a little easier to support doors, drawers, and other large parts during clamping.

Before even sharpening a pencil for this project, make sure you have your vise and bench dogs on hand. Open the vise fully, measure the opening, and then subtract the thickness of the jaw (see the Material List below). This is the maximum spacing that you can allow between the dog holes in the bench top, but you may want to downsize that spacing a little; traditional bench builders have discovered that a space of 6" or 7" works best for most projects.
