I thank everyone for their kind help. @Skurj, I am extremely grateful for all of your help, and I appreciate your detailed responses. My instructor confirmed the idea today, I will start the construction tomorrow. He says the plan seems to be very solid. However, I will actually be using the laser for the lines instead of the sharpie despite what I had planned. Using the laser is going to be a lot easier than I anticipated, and my instructor said that it will be safer. In addition, he said that we can simply etch the lines to appear very dark on the board instead of using some filler. Here is a brief summary of the planned procedure:
-
Rough-cut oak stock to 19 1/2 inches
-
Square one side of board
-
Rip-cut these planks into 2 1/4 inches (this will eventually be the thickness of the board)
-
Square all sides of all stock, then face to face glue-up of stock
-
Plane to final thickness, sand, laser lines, and use polyurethane for finish
Again, I thank everyone for their help and if anyone sees a problem with this procedure or has any suggestions I will be glad to hear them.
