You can get grinding wheels for these from Silvey, Bailey's, or
Madsens. Bailey's is a little more expensive than the others on
grind wheels.
There are several 8" wheels available. The standard wheel is the
Salmon wheel but you can get gray and white ones too. There is a
blue wheel that costs twice as much but it lasts longer that
Bailey's sells.

I have pictures of the Simington 450 and 451B grinder
instructions if anyone is interested but I will have to Email
them to you.

My early model 1979 Silvey Swing Arm Grinder that at one time
had a red body, (Now mostly natural - as cast - aluminum.) and
what was originally a gold anodized arm. It has a new salmon
grinding wheel from Silvey. Most of the fasteners and all the
springs are new from the local hardware down the street but the
diamond dressers are the original as well as the motor and
switch. The original cord had been replaced by the previous
owner.
Simplicity itself.

The new Silvey Swing Arm grinders have a different motor with
small vent holes around the sides that is bolted on differently.
Also the chain holder on the new style can be raised up and
down.

Notice in the pictures of these different grinders, they all use
the same size 8" wheel, but you see a gray one, a white grinding
wheel and a couple salmon color wheels. The white is easy to see
but disappears faster than the others. Silvey recommends the
salmon wheel which you can get from Silvey, or all of them from
Bailey's or Madsens.

Here are a series of Silvey Prosharp Square Chain Grinder
Details. This is more or less considered a Cadillac of The
Silvey Product Line. It is not currently produced and carries a
possible $2,000 price tag. This grinder is not set up on a stand
or mounted against the wall for use but is laying on its side on
a table.
To pull up on the lever places the chain cutter tooth into
position at the grinding wheel. There is a cable arrangement
actuated by the slide that pulls on a lever of the chain vice to
hold the chain steady. Then you turn the crank to feed the chain
cutter into grind wheel. This action presents the whole dressed
surface of the grinding wheel to the chain tooth at once. This
lets the all important dressed corner last much longer than on
the swing arm grinder whose feed action makes the top of the
dressed corner do all the work in grinding the inner face of the
top plate as it wipes across the under surface. This is a
feature of the Pro Sharp and SDM4 that makes them shine over the
Razur Sharp II and Swing Arm versions.
There are pre-set marks for the dressers and all the other
angles to make work chains or race chains. But you still have to
make sure that the dressed working corner of the grinding wheel
meets exactly the outer corner of the cutter on the chain.
I would like to mention here that there is a fourth Silvey
grinder design (SDM-4) that has chain rail holders like the Pro
sharp. But there are two of them and it is more or less a cross
between the Pro Sharp and the Razur Sharp II. The chain rails
are fastened on slide mechanisms and are fed into the grinding
wheel a little like on the Razur Sharp II but the grinding wheel
is mounted up at an angle.
The Pro Sharp chain rail assembly will pivot left and right for
the opposing cutters. The motor is reversible.

That's the best pictures I've seen of a pro sharp. I would like
one but never would come off with the money.

Here are a series of Silvey Razur Sharp II Square Chain Grinder
Pictures. The grinder is more related to the swing arm grinder
than the Pro Sharp series. The Razur Sharp differs from the
swing arm in that it has two separate chain holders. One on each
side. You sharpen the right hand cutters on one side and then
move the chain over to the other side to do the left hand
cutters. The chain holders are mounted on a common slide
mechanism fed by a single lever on the end of the machine. This
grinder is commonly mounted on a tripod style stand. Actually,
the grinder is light enough that it can be moved out of the way
when not needed. This particular one is not mounted on a stand
but is setting on a piece of slab wood on a big rock. It was
moved out doors for the pictures.

Silvey Razur Sharp II Top View from the mounting end. Note the
mounting hole at the bottom of the picture where the grinder
assembly mounts on the stand. Also take note of the off-on
switch mounted on the motor. Typically, the switch is pulled
towards you when you are in the operator's position to make the
grinding wheel turn in the proper direction to approach the
cutter tooth you are sharpening from the outside. I this picture
you can see the two grinding wheel dressers. There's one for the
edge of the wheel that shapes the side of the chain cutter tooth
and there's one for the top of the wheel that forms the top
plate angle on the chain's cutter tooth.

One glimpse at the grinding wheel in these pictures tells me
that the all important corner is dull and needs to have the
dirty color lightly dressed from the corner and another light
pass taken on the cutters before the chain sharpening is
finished. I can tell that the top angle on the stone is dull
because it has a dirty look to it right at the corner.
HTML http://img.photobucket.com/albums/v11/jamesirl/simington450.png
Even watching this video of the German sharpener, I can see the
grinding wheel is dirty in the corner as Rich is taking pretty
healthy cuts on the chain. He will need to touch up the stone
and make a light pass on the chain before it is finished. You
will notice that the top side of the corner gets dull first as
it has to do the most cutting.

Very nice presentation 660magnum. It is great reading and full
of lots of good information. I would like to have a square
grinder but I am not up for the kind of money it takes.
