Installation Guide

Once you have your MICRODIAL Tapering Jig set (pages 12-17) it is time
to attach your GRR-RIPPER 3D PUSHBLOCKs and make the cut(s). The jig
is designed to work with one (or for longer pieces, two) GRR- RIPPERs
ADVANCED MODEL (GR-200). GRR-RIPPERs provide both a secure grip on
your workpiece as well as handles to keep your fingers protected from the
blade. When the GRR-RIPPERs are attached to the jig, extremely safe and
accurate tapers are possible.
MAKING TAPERED CUTS
20
1. Attach your GRR-RIPPER to the jig
with the included T-bolts and knobs.
These engage the slots in the GRR-
RIPPER’s Balance Support. Be sure
the Balance Support is fully inserted
under the knobs and doesn’t stick
out past the edge of the tapering
jig. You may need to experiment
a little with the front and back
positioning to make sure the
GRR-RIPPER isn’t in line with the cut.
2. Adjust the GRR-RIPPER’s Center
Leg laterally so it rests firmly on the
workpiece, but off to one side of
the cut line. It helps to have the cut
line drawn on your piece so you can
clearly see where the cut will be.
NOTE: If necessary, the Center Leg
can be removed from the
GRR- RIPPER if it cannot be
positioned off of the cut line.

3. For narrow pieces, such as table legs,
the outside leg of your GRR-RIPPER
may hang out beyond the edge of the
workpiece. In this case, add the GRR-
RIPPER’s Adjustable Spacer
along with a user-made riser block for
extra support. Riser block size
and dimension will vary depending
on the dimensions of your workpiece.
Press down firmly on the GRR-RIPPER.
Tighten the knobs to ensure the GRR-RIPPER has good traction.
4. With the spacer in place, adjust the
rip fence so the blade enters the
workpiece where you want the taper
to begin. Make sure the workpiece
is against the jig’s edge and butted
against the heel at the rear. Align the
taper starting line on the table leg to
the front tip of the saw blade, or draw
a reference line on the throat plate
as a alignment line. NOTE: Raise the
saw blade no more than 1/4” (.25”) above the surface of the workpiece.
Ensure that the saw blade passes through the GRR-RIPPER tunnel.
5. Guide the jig along the fence
to make the cut, keeping both
hands on the handles. As the cut
progresses, you can shift your grip
from handle to handle depending
on what feels comfortable.
