« on: June 08, 2013, 02:18:53 pm »
Whats the angles supposed to at for Stihl 33rs chain? What grinder size grinding wheel am I supposed to use 3/16 or 1/8? The 3/16 is rubbing that dog ear piece of metal on the cutter link in front the cutter. I have angles set @ 60 and 25.

1/8" is correct

Don't forget the 10 degree droop

I dont know the numbers on the oregon being I use a USG.

Stihl USG Saw Chain Angles Chart  http://www.stihlusa.com/WebContent/CMSFileLibrary/instructionmanuals/USG_sawchainangles_chart.pdf    where it says 15 at B I do 10.

I use the grinder for bulk or setting up trashed chains back to normal.   I used to do 25 because I figured it would stay sharper a little longer.   I then sent some 30 out and the regulars like the cut of the 30 better. 

So I grind and hand file at 30.

I was told 25/60 cuts better on hard wood but 30 is good for softer wood like pine, etc.

The 3/16" is normal for 3/8" chain

But with the new unsharpened Stihl RS chains, the distance between the cutter and the raker are so close that your first couple sharpenings will have to be with the 1/8" wheel. Then you should return to the 3/16" wheel.

Some have been known to just use the 3/16" wheel from the beginning that takes away a little of the raker on the back side. In this case, I doubt you would notice the difference on the chainsaw?

Yea, looks like the 3/16 wheel is gonna take off like a 16th of raker. The 511a doesnt have setting for 10 degree drop.

I have a Oregon early 511A grinder. It has the 10*  droop capability for the chisel chains. The Oregon 510A is the one that doesn't have the 10* droop feature.

Other than the droop feature, the 511A & 510A grinders are identical.

Later on there was a 511AX that had a red twist handle for the vice chain grip instead of the cam action swing arm.

The 511AX was later changed to have little spring loaded discs on the ends of the vice. These two 511AX vice designs will fit right on a 511A grinder if you buy the whole vice assembly

The individual rail parts of the cam action swing arm grip type vice of the 510A and 511A are not common with the corresponding parts of the 511AX vice variations. The chain stop assembly is common between the two designs.

In 2012, the 511AX was changed again to have a different style 10* droop feature that slides the swivel base front and rear for the droop feature rather than tilting the vice. This design will not work on the 511A or the earlier 511AX designs.

I am not very good at manually filing my chains, probably just lack of experience or guidance.
Anyway I have been looking for an Oregon 511A for some time now and finally found a nice, gently used one at a VERY reasonable price.

Most of my chains are Oregon 72's and Husqvarna H80's.

In the manual for the Oregon 511A, the "top-plate cutting angle" for these chains is stated to be 60*

However in the link provide above...
http://www.oregonproducts.com/pdfs/GrindingAngles.pdf
the angle is 55*

Just wondering if I am reading something wrong or which angle should I use.
