Compensating for Wheel Wear

Your grinding wheel will gradually become smaller in diameter as you dress the stone with
the diamond dresser and sharpen chain. This can be compensated for by sliding the chain
carriage assembly closer to the grinding wheel.
This adjustment slot is located on the grinder housing pictured.
Use the diameter scale on the top of the grinder to determine
the size of the stone. Use the scale and pointer under the
grinder to match chain holder mechanism with the wheel
diameter.
This adjustment allows the operator to keep the location
where the cutter tooth comes in contact with the arch of
the grinding wheel the same, even though the wheel
diameter wears smaller.
If you like your top angle blunt, lag behind the scale when compensating for wear.
If you like your top angle greater, lead the scale a little.
Fine Tuning
There is not one formula for sharpening chisel chain on which all Professional filers
would agree is best. Everyone who runs and grinds chisel chain has their own grinding style.
Some of the factors that determine the type of grind that will work for you are size and type of
wood being cut, the kind and size of saw that is being run and so on.
Outlined in the next section are some guidelines that will hopefully give you a place to start in
developing your own grinding style.
Reshaping the grinding wheel
1)The mounting blocks for the diamond dressers for the wheel may
be pivoted. This will change the grinding wheel shape by changing the
path of the diamond dressers.
2) The shape of the chain's cutter face is greatly affected by the
shape of the grinding wheel. The angle of the outer edge of the
wheel is a determining factor in the angle ground into the cutter's side
plate.
The angle of upper dressed surface of the wheel is a determining factor of the inner angle
ground into the cutter's top plate and also determines the outer top plate angle.
