PIVOT FRAME JIG
-8-
ASSEMBLY
Mini-Pivot & Ski Frame
■
Screw the four studs into the larger-diameter
end of the four shoes. The stud should be
screwed almost to the bottom of the shoe, but
must not be allowed to protrude beyond the
end. The fit of the stud in the shoe may be
tight. In this case, the stud may be held in
soft vice jaws. Repeat the operation for the
remaining three studs and shoes.
■
Fit the shoe/stud assembly to the outer-most
holes in the pivot bars, using three shoe
spacers per assembly. The spacers are
intended to offer a choice of ‘ride-height’ of
the router above the workpiece. Finally,
screw the shoe locking knob hand tight on to
the spacer.
■
Screw the four guide rod locking knobs lightly
into the tapped holes immediately above the
fence rod holes, from the same side as the
knobs which lock the shoe assemblies. Slide
the fence rods into the router and temporarily
lock in position with the locking knobs which
form part of the router.
■
Slide a completed pivot bar assembly on to
each end of the fence rods, and temporarily
lock in position by means of the guide rod
locking knobs.
■
The next step is to allow fitment of the fine
adjuster. The M6 stud is threaded onto the
tapped hole and an M6 locking nut is
tightened against router base. If your router
does not have a tapped hole in the edge of
the base similar to the Trend T5 then the
router base must be drilled out and a thread
tapped. The following routers will need
modification:
Black & Decker BD780, 780E, KW779,
KW780(E), 800(E), 850ET
Bosch GOF 900A, 900ACE,
Elu MOF69 and Makita 3620
The edge of the router base must be drilled in
the correct central position to align with the
hole in the pivot bar when fitted on to the
guide rails. The pivot bar can be used as a
drilling jig. The hole diameter must be 5.0mm
and 6.0mm deep. An M6 x 1.0mm pitch tap
must then be used to thread the hole.
■
For the Hitachi M8, M8V the base of the
router has a recess which will accept a M6
nut so giving the same facility as a threaded
hole.
In the freehand ski-frame mode, it
may be found preferable on occasion
to work with the shoes reversed on
the studs, ie. with the large flanges
in contact with the worktop. This is
best effected by removing the shoes,
reversing and re-fitting them to the
same end of the studs. Do not wind
the shoes along the full length of the
studs, as unnecessary wear of the
nylon screw-threads will occur.
