XIX. USING THE MODEL G1793 ROUTER BIT SPINDLE
- 35 -
The Model G1793 Router Bit Spindle is a handy accessory available for your Model G1024 shaper,
which allows you to use your standard router bits as shaper cutters.
Using the optional router bit spindle does require some minor modifications to the Model G1024.
To maximize the effectiveness of the router spindle, it is necessary to build a false table to increase
the height of the shaper table by 1
1
/2". To make a false table:
1. Cut two sheets of
3
/4" hardwood plywood or MDF-grade particle board slightly larger than the
size of your shaper table’s surface. Face glue the two pieces together. After the glue has
dried, you can either cut the pieces down to the exact size of the shaper table, or let them
extend beyond its edges.
2. To create a smooth working surface, attach a plastic laminate, such as Formica or Wilsonart,
to the top of your false table.
3. Disconnect your shaper from its power source and tape a sheet of tracing paper to the
shaper’s table. Be sure to align the back edge of the tracing paper with the back edge of the
machine to use as a reference guide on the false table.
4. Locate the four fence mounting holes and the opening for the spindle by rubbing a pencil over
those areas. Do this for the starting holes as well. Transfer all of your marks to the false table.
5. Drill the four fence mounting holes and the two starting pin holes with an
11
/32" drill bit. Cut the
spindle opening with a hole saw or saber saw.
6. If you intend to use your miter gauge with your router spindle installed, cut a straight slot
3
/4"
x
3
/8
" parallel to the existing miter slot.
7. Mount your false table to the shaper’s table top, using two 8mm-1.25 x 150mm fence bolts.
NOTE: If most of your work calls for edge forming bits (roundover, cove, chamfer and so on), a
1
1
/2" table should be sufficient. On the other hand, if you desire to use more complicated bits, you
might want to add a third layer to the false table, bringing it up to 2
1
/4". If you choose to include that
extra level of height, remember to make suitable adjustments to the height of both the fence bolts
and the starting pins.
CAUTION: The Router Bit Spindle is made for one-direction operation. Reversing the direction of
the cutter travel could result in the loosening of the collet, making it possible for the bit to loosen
and unexpectedly exit the spindle.
