Step 7Make the mill column
To make the mill column take the four pieces of plywood that measure 9" x 12" and glue them together using wood glue and clamps. After the glue has dried overnight, check that it is square and that the ends are flat. If not, you can use a bench plane to flatten the ends.
Now I used a 1 1/4" Forstner bit to cut the radius on the inside edge and then cut the inside with my trusty jigsaw. Four 1/2" holes are then drilled and wood dowels are glued in.
The column then gets glued and screwed to the back center of the 18" x 11" plywood base using 2" long #10 wood screws. I always countersink the screw heads- do this using a #10 countersink.
If you don't want to go to the trouble of making a laminated plywood column you can make one from 1 1/2" plumbing pipe (see drawing.) You might have to shim the flanges to get it to sit square and level.
