The first task was to design the shape of the guitar.  I drew out the shape on the poster board and transfered the shape to a sheet of Plexiglass.  I am starting out by building the side forms, so I cut out the right and left sides profile from a sheet of plywood.

(2) June 15,2009
I estimated the shape of the sides and cut it out of a piece of wiggle wood.  Wiggle wood can be obtained from the very rare and valuable Wigglewood tree which only grows on the north side of very crooked streams.  

(3) June 15,2009
I press the first piece of wiggle wood into the side form and screw it into place.

(4) June 15,2009
I do this to both sides.

(5) June 15,2009
Before I can continue I have to cut some angle iron that will be used to join the right and left sides of the form together.

(6) June 15,2009
Drilling holes for the bolts.  The angle iron firmly holds the sides together and keeps The two halves straight.  I cut slots into the iron so I can get it on and off without having to fully unscrew the nuts.  I use wing nuts so I can assemble everything by hand.

The two halves now are joined together with the angle iron.

(8) June 15,2009
At this point the sides are only approximately in the right shape. To get them into their final shape I use the top and back forms with a sheet of sandpaper to sand the sides to the proper profile.  

(9) June 15,2009
To build up the sides to their final one inch thickness I cut strips of wiggle wood to be glued onto the existing pieces.

(10) June 15,2009
All of the side strips get glued together at once.

(11) June 15,2009
And here is where the one with the most clamps wins.  

(12) June 15,2009
After the glue dries over night a little bit of sanding brings all of the pieces into the same profile.

(13) June 15,2009
And here we see the side form in its final shape.

(14) June 15,2009
I will use the piece of plywood that I cut for the side forms to make the form for the Universal Bendalator.  I have to trim the plywood down by 3/4 of an inch first.

(15) June 15,2009
I use the bandsaw to trim the the pieces.  I will use the trim from this operation to make a spacer for the side mold.  I try to use every piece of wood for something useful.
