				| Put the jig base together
 After cutting the 12 foot 2x4s to proper length for the jig, I used my pneumatic brad nail gun to put the base together. The center beam is "T" up with the two 4 foot end footings, dead center on each.  I finished attaching the plywood up by putting in some 2 1/2" wood screws into the 2x4s.
