Step 3Mark and Drill Inner Dowel Hole.
iImage Information

On the top end of the shaft, mark a line from each corner cross-wise to create an "X". The point where the two lines cross is the center of the shaft. Clamp the shaft so the surface is 45 degrees square from the drill shaft. While machine is OFF - Use a 5/8" Forstner Bit and mark the center of the "X" by indenting the bit into the wood. (This will help the bit find the mark and not jump when starting to drill.) Turn on machine and drill 1.5" deep. [Hint: The shavings should be vacuumed while drilling and you may need to bring the bit up to the surface to remove dust/shavings otherwise they may compact and jam. This can also heat up the bit and start to burn.]
