To Assemble:
Verify that all parts shown in parts list are included.
Check that drawing board has a solid outer frame to hold
screws and that it is not warped. Alvin straightedges will
not work properly on warped boards.
Position front and rear wire connectors (
C, D, E
) on top
of drawing board as shown in
Figure 1
. Use chart below
to determine proper spacing. Center the straightedge (
B
)
on the board.
Mark screw positions for front and rear wire connectors
and pre-drill pilot holes about 1/4" deep using a
1/16
"
drill bit. Use care not to drill through the board.
TIP
Wrap masking tape 1/4" from drill tip
to set drilling depth.
Fasten front wire connectors to front edge of board as
shown in
Figure 2
using 3/4" screws (
J
). Fasten screws
half way. Do not fully tighten.
