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.
