TAPER CUTS
A useful jointer operation is cutting an edge to a
taper. The method can be used on a wide variety
of work. Tapered legs of furniture are a common
example. Instead of laying the piece on the infeed
table, lower the forward end of the work onto the
outfeed table. Do this very carefully, as the piece
will span the knives, and they will take a "bite"
from the work with a tendency to kick back unless
the piece is firmly held. Now push the work
forward as in ordinary jointing.
The effect is to plane off all the stock in front of
the knives to increase depth, leaving a tapered
surface. The ridge left by the knives when starting
the taper may be removed by taking a very light
cut according to the regular method for jointing,
with the infeed table raised to its usual position.
Practice is required in taper operations, and the
beginner is advised to make trial cuts on waste
material. Taper cuts over part of the length and a
number of other special operations can easily be
done as the operator gains experience.
RABBETING
WARNING: A rabbet cut requires
removal of the cutter guard. Use
extreme caution and keep hands clear
of cutterhead. Always replace guard
immediately after rabbeting operation is
completed.
A rabbet is a groove cut along the edge of a
board. The width and thickness of the wood to be
rabbeted depends upon the width and length of
the rabbet. However, never rabbet a piece of
wood less than 12" long. Use push blocks to
rabbet cut whenever possible.
1.
Disconnect machine from power source.
2.
Set fence for the desired width of the
rabbet.
3.
Check the width of the rabbet by
measuring the distance from the end of a
knife in the cutterhead to the fence.
4.
Lower infeed table 1/32" at a time and
make successive cuts until the desired
depth of rabbet has been obtained. See
Fig. 31. NOTE: It is easier and safer to
take a series of shallow cuts.
