Step 6: Attach Handle
There are two ways to attach your Handle. The first method,
connecting your handle directly to the sliding base, is the easiest and
simplest to setup while the second method, using the included control
arm, takes a bit more to setup but provides for smoother operation
when routing your notches.
To connect the handle directly, start by barely threading the ¼ nut
onto the handle. Then, remove the plastic cap using the ball-end
allen wrench and slide the handle into position wherever it’s most
comfortable. To secure, firmly rotate the handle clockwise to tighten,
then reinstall the plastic cap.
To utilize the control arm, you’ll need to follow the assembly diagram on
page 6 and 7, paying close attention to the positioning of the washers.
With everything in place, barely thread on the ¼” nuts, remove the
plastic caps as necessary, and slide the two pivot points into position
as shown.
The stationary pivot point of the stationary block should be locked down
roughly 1” from the end of the sliding base, while the movable pivot
point should be positioned and secured about 2-1/2” from the end of
the sliding base. When correctly assembled, the handle should be able
to fully extend without coming in contact with the fence, providing the
full range of movement allowed by the sliding base. When complete,
reinstall the plastic caps.
