Woodhaven 3230-3250: Oval Jigs - Manual (Page 2)

BEFORE BEGINNING
Identify and verify that you have all the parts listed. Read
the instructions at least once, familiarizing yourself with the parts
before beginning. You'll need a #2 & #3 Phillips screwdriver
and a framing square or measuring tape for assembly.
DETERMINE USE
There are several ways to mount the T-Tracks, depending on
the desired work setup. The top of the T-Tracks must also be mounted
at one of three different heights in relation to the top of the work: 1.
At the same height as the top of the work. 2. 1/2" above the work.
3. 1" above the work. Keep in mind that the higher above the work
you mount the tracks, the longer bit you’ll need to make the cut.
Option A: T-Tracks are mounted directly on (1/2" above) the work,
for example a solid table top. Or mount the T-Tracks to a 1/2"
plywood base (1" above), then mount the plywood to the work.
Option B: T-Tracks (and/or plywood base) and work are mounted on a
bench and the work surrounds the tracks, for example a segmented open
frame. Tracks must be even with top of work, 1/2" above or 1" above.
Option C: Mount three T-Tracks if only half an oval (or less) is needed.
Tracks must be even with top of work, 1/2" above or 1" above.
ASSEMBLY
Mark the center of your work, or center the tracks on a square
piece of 1/2" plywood to serve as a base. Depending on the Oval
Jig model purchased, you’ll need the following size square piece of
plywood to mount the T-Tracks to: 3230: 17-1/8" square, 3240: 34-
1/8" square, 3250: 68" square (requires two pieces of plywood joined
together), 60" or 48" square (won’t allow use of all mounting holes).
Align the pointed ends of two T-Tracks (3230T, 3240T or 3250T,
depending on model) together at the center to form one continuous
track. Take the assembly plate (3250C) and insert it between both tracks
and snug the tracks against the assembly plate. Use a third track as a
straightedge to align the two tracks in a straight line. See fig. 1.
Drill pilot holes with a self-centering bit and fasten the T-Tracks
to the work, or plywood base, using the 5/8" screws (SFC001). Remove
the assembly plate and place the two remaining tracks so the points
intersect with the two tracks just installed. Using a framing square,
or measuring from corner to corner, position the tracks so they're
square to each other and fasten with the 1/2" screws. See fig. A.
