Oregon Chain Grinder vs. Stihl chain angles
« on: July 07, 2013, 09:24:01 pm »
Hi folks,

Question about Stihl chain angles.

I have an Oregon 511A Bench Grinder and I run Oregon chain which is great, however I am trying to grind Stihl PMC3 chain for a buddy and I can't seem to translate the charts.

I have three variable angles on the grinder.  The grind angle ajustable on the back, the top plate angle and the vice-tilt angle.

The grind angle runs from 90 degrees thru to 40 degrees. 

The top plate angle runs from -40 degrees thru 0 to + 40 degrees

The vice tilt isn't marked but it seem to run from - 10 thru 0 to +10

All of this is fine for Oregon but there seem to be more numbers for Stihl.

According to the Stilhl USG Chart, PMC3 has an "A" angle of 40, a "B" angle of 15, a "C" angle of 30 and, from what I can interpret, a grind angle of 75...

I am guessing C is the top plate angle but I don't get A or B.

Anyone?   Anyone?   :)  (head spinning... seriously)

Cheers,

JP

Chelsea,thats the germans they have specs and dimentions for puppy poo.Put the chain on your sharpener and sharpen it as your own.If your buddy complains it doesn't cut then change the angles. Frank C.
