Chessboard Project
These directions are very important. Please become comfortable with following detailed instructions; it is an important part of this class!
1. You will need two different types of wood. Two completely different colors would be nice. Start with four strips of each color. For each color you will need 1 Board 2” x 24” and 3 Boards 1 3/4” x 24”.
2. Glue the strips together. See Figure 1 on reverse side of this sheet. Try to make the boards as flush as possible.
3. Have the board surface-planed after scraping off all the glue residue (from under the clamps). This is the only time you will scrape the board!
4. Square one end of the board on the Radial Arm Saw. Double check with a tri-square before cutting into strips.
5. Re-cut the boards on the Table Saw into 1 3/4” strips. Begin with the squared end against the fence.
6. Re-glue the boards making sure to line up the squares, and making sure that the board is as flush as possible. Use scrap wood on each side of the board so that the clamps do not dig into the boards. Give Mr. Kosberg the extra strips for use later when students wish to make a 2nd and 3rd chessboard.
7. You will install your First skirt boards now BEFORE you do any sanding or any cutting of the board of any kind. Repeat out loud five times: “I Will Put On All Four Skirts Before I Do Any Sanding Or Cutting On The Checkerboard.”
8. Cut the First two skirt boards. They should be 1 3/4” x 14 5/8”. Follow the diagram on the other side of this sheet for the proper placement of screws. Attach the first two skirts to the board using glue and screws. Always use lightweight clamps for this operation.
9. Trim one end of the board (and skirts) using the Table Saw. Please ask to be shown the technique for setting the board at the correct angle on the table saw.
10. Make the board parallel and to finish size using the Table Saw. You want to produce a perfect flat surface, while leaving the board as big as possible
11. Cut your second set of skirts. They should be 1 3/4” x 16” or so. Make them exactly the length of the board and skirts. Using the diagram on the reverse side of this sheet mark out and drill the holes for the second skirts. Attach the second skirts using glue and screws.
12. Now you may begin sanding. Install the wood plugs. Fill in any small gaps with glue.
13. Route all surfaces with the round over bit. Sand everything better than you have ever sanded anything before. Learn to play chess!
