skill level before starting assembly!

Phase 1: Breadboard preparation

! Find the pine board. Look it over carefully, and select which side you wish

to use for mounting the parts. Chose the side that has the fewest
imperfections, and has the nicest looking grain pattern.

! Locate the drawing that shows the screw hole pattern for the pine board.

! Place the screw hole pattern guide over the board, be sure the board edges

line up with the outline on the drawing. Use masking tape to hold the
pattern to the board.

! Using a finishing nail and small hammer, make a small punch mark at each

of the eight screw hole locations. These marks will show you where the
screw holes are located on the board. Don’t drive the nail into wood! We
need only make small indentations, about 1/8”, to mark the screw locations,
and to provide pilot holes for the wood screws.

! Remove the paper pattern guide.

! Find one of the eight Phillips head screws and a Phillips head screwdriver.

! At each of the eight screw hole locations marked by the finishing nail, screw

the Phillips head screw fully into the board, stopping when its head reaches
the board surface. Make sure the screw remains perfectly straight, and not
tilted, when doing each of the eight holes.

! Return the screw to the parts bag.

! Find the 5-inch length of PVC pipe. The tuning coil will be wound on this

section of plastic pipe. It is called a coil form.

! There are six holes drilled through the pipe, look for the two outer, and

larger sized, mounting holes.
