FIGURE 5
CUTTING SPEED
You may vary the R.P.M. depending on the diameter
of the ring. Cut the largest 10-11" dia. rings at slow (700
R.P.M.) and raise the speed NOT TO EXCEED "C" (900
R.P.M.) for the smallest rings.
RING MASTER® OPERATING
INSTRUCTIONS
Now that you have set up the RING MASTER® to
properly cut your rings, you are ready to begin. Remember
to observe proper safety precautions when operating the
RING MASTER®.
Start motor, turn lead screw clockwise and advance left
blade very slowly into the wood. (NOTE: When cutting,
always advance the blade slowly. Should you attempt to
cut too rapidly, you may experience chattering, vibration,
checking of your work piece, or misalignment of the cutting
blade.) Since each revolution yields 1/13" of movement,
advance slowly for about six turns in 3/4" wood or until
halfway through wood. Then reverse the turn and start to
cut from the right side. Move slowly until you notice a
change in the sound of the cutting. As the ring starts to fall
off to the right, STOP the motor and clear the ring from the
machine. You will have to unlock the slide lock to remove
the ring.
You'll note the outer shape of this first ring is octagonal
and will not mate with any other ring, lay this ring aside for
OTHER use.
To cut the next ring adjust the blades to clear on both
sides of the ring and slide forward for the next cut. Replace
the index pin and lock the slide. NEVER ATTEMPT TO
CUT A RING WITHOUT FIRST LOCKING THE SLIDE
LOCK. Repeat the process explained above to cut your
next ring.
After cutting two rings, stack the small ring on top of
the larger as shown in FIGURE 6. This will indicate if the
cutting angle is correct. (NOTE: Having calculated and set
the cutting angle on the degree scale is no guarantee that the
rings will be cut with a good alignment. A good match of
the rings can now be accomplished with minor adjustment
of the cutting angle. If the top ring is larger at its base than
the bottom ring, the angle must be decreased slightly. If the
top ring is smaller at its base than the bottom ring, the angle
must be increased slightly. If the rings do no match closely,
adjust the angle and cut TWO more rings to check for
acceptable alignment.
Good Alignment
Increase Angle For Good Alignment
Decrease Angle For Good Alignment
