Cut a piece of particle or flake board. 3/4" by 8" by 10"
Sand or file a 1/8" radius on all edges and corners except the four
edges that will be the bottom of the base.
Now drill six holes through the base for the side mounting screws.
a piece of masking tape 2" long on the left lower outer edge of the
10" length facing you.
Put a second piece of masking tape on the left side edge of the 8"
width to your left.
Now , with a marker, write a "X" on the tape on the 10"
Write a "Y" on the tape on the 8" edge.
Now, you have established reference edges for the hole locations.
Mark the first hole location. it is 2" from X edge, and 1 3/8"
from Y edge.
Drill a clearance hole for a 6 - 32 screw through the base.
Use a # 28 drill (.140" Diameter).
Now, drill a second hole 2" from the first hole, and at the same
location from the Y edge of 1 3/8".
Next , drill a third hole 2" from the second hole, and maintain the
1 3/8" from Y edge.
Now, mark and drill a fourth hole that will be located 8 5/8" from
the Y edge. It will be located at 6" from the X edge as the
third hole is.
Next, The fifth hole is located 4" from the X edge and 8 5/8"
from the Y edge.
The sixth hole is located at 2" from the X edge and 8 5/8" from
the Y edge.
Lightly countersink the holes just enough to break the edge.
The base is now complete except for finishing with polyurethane or varnish,
