Reshaping The Wheel - Silvey RAZUR SHARP II Owner's Manual

RAZUR SHARP II
The diameter of the grinding wheel and the location on the arch of the wheel where the cutter
tooth comes in contact with the grinding surface are also determining factors on the angles
ground into the cutter tooth.
(See: Compensating for Wheel Wear. In the Maintanence section)
When changing the angles of the mounting blocks, move them only a small amount, redress
the grinding wheel and then test grind.
A little change has a big effect on the grind in the cutter tooth.
3) Make sure that the leading edge of the stone is thick enough to remove some of the gullet
area but don't make it so thick that it cuts deeply into the tie strap under the cutter, this
weakens the tie straps. Surface strength is important to the cutter chassis.
Chain breakage, that would otherwise not develop, often occurs on tie straps that have been
ground into.
Changing the Inner Angle of the Top Plate
1) The inner angle of the top plate is changed by lowering or raising the grinding stone
holder. To raise or lower the grinding stone you must first remove the lower shroud guard
and the nut and support washer that hold the stone onto the holder.
There is an allen head set screw located in the thread area of this holder.
2) Generally, a thicker inner top plate angle will keep its edge a little longer. A thinner angle
will cut better but will get dull faster.
This grinder will grind thicker top plate as the cutter plate tooth becomes shorter. You may
want to adjust for this if you have a series of chains with short cutters to grind.
If you prefer thicker inner angles on new chains, lowering the grinding wheel will cause the
grinder to cut thicker top plates.

You probably noticed it when you changed
grinding wheels.
This set screw can be loosened and the holder
will slide on the motor shaft.
Adjustments to the stone should be made a little
at a time, as small changes make big differences
in the grind on the cutter tooth. Be sure to tighten
all screw and replace the guard before operating
the grinder again.
