Our CNC router finished off first two layers of Precision Board HDU quickly because we had used a large diameter bit to route them. We glued these up over a simple welded steel frame. By the time the second set of pieces came off the CNC router, the previous pieces were dry enough to add the new ones to the assembly.
The next morning everything was good and dry. The clamps came off and the fun began! First we gave the entire piece the once over with our air powered die grinder. We trimmed up the glue joints, textured the edges and aded some extra character here and there making the sign look well used.
Next we sawed the old stand off the model plane and drilled a new hole in the bottom for a 1/2" steel rod. By lining it up with one of the balloon tires the rod was well disguised.
