Need proper 1/2 chain sharpening

[295 tramp]

Hi I have a couple of round tooth 1/2 pitch chains I want to sharpen with my 511a grinder.
The chain is Oregon and the number 10 on the driver. I have a 1/4 inch wheel but not sure on the setup angles.
thanks

Id try 25/55/0 personally.....set the gauge tooth at .030 - .035 and go from there.

Looking closer this morning, that tooth is half gone. Don't be scared if you have to go a little lower on the rakers. I'd test cut first though, always take some off, can not put it back.

What oldie you running it on?

I have lots of files for 1/2 if you need any.

You could also try to 'match' the existing angles with your grinder, then read the settings off of the scales.
