What is the recommedned grinding angle on a ripping chain?   Seems I read somewhere that 10 deg was recommended.  But, I recently bought a chain that is ground toa 20 deg angle ???
Been there, done that.   Never got caught [/b]
Retired and not doing much anymore and still not getting caught

Somewhere between 0-10 degrees. Some people alternate every other tooth left to right. Bunch of different ways. The ripping chain Baileys sells is 10 degrees for all cutters.

10o will give you a smoother cut than a top plate angle of say 25o.

The stihl pmx ripping chain logosol sells is ground to 5 degrees.  I've nice smooth cuts with it

I do not know the mechanics of why, but, on a chainsaw mill the 10 degree cuts way faster then the 25 degree and runs way cooler.

We use Oregon chipmaster,   One thing I have found is, if the cutters have rounded edges to the chisels, they give a much better finish than a square/sharp pointed edgeds to the chisels,  because they are taking less timber from inside the bottom edge of the cut, I use an angle of between 05 and 10.
If you are using a saw with a slightly longer bar than is recommended, cut every other top off the chisel, but leave the side raker behind for clearing the edges, then the saw will handle thing better, progress will be a tad slower, but easier on the motor.
