Note: Circular saws are an acceptable substitute for a table saw. If you're using a circular saw, clamp a straightedge in place to act as a fence or guide (figure A). It's also important that you keep a sharp blade and that the blade is square. You can check this by first unplugging the saw and then checking the blade with a combination square.Steps:
1. Take the initial measurements.
2. Before you begin, get a rough estimate of the depth and width for your kitchen island.
Use the size of the tiles, factoring in the space for the grout lines, to fine -tune the measurements so you won't have to cut any tile later.
3. Cut the counter top, bottom shelves, and apron pieces.
4. Using a table saw, cut the counter top and bottom shelves to size from a 4 x 8-foot piece of 3/4-inch plywood.
5. Next, cut three lengths of plywood to form the back and side apron pieces.
6. Make or purchase the table legs. The legs for the kitchen island should be sturdy. You can turn them yourself on a lathe, or you may want to have someone else turn them for you. You may also be able to find appropriate table legs in your local home improvement store.
7. Make dado cuts in the table legs.
8. Install a dado blade on your table saw and set it to make a 3/4"-deep cut in your table legs for installing the apron boards. If you don't have a table saw with a dado blade, you can also use a circular saw, making several long cuts near one another and chiseling out the waste, or a router with a dado bit.
9. Place a stop on the saw to help you make cuts at the appropriate length.
10. Use a scrap piece of wood to check the length, depth and width of the dado cut. The length should be exactly the same as the height of the apron boards, and the width should be exactly the same as the thickness of the apron boards.
