For over 40 years now I have used an older Stihl hos chainsaw sharpener probably made in the late 1960s or early '70s in fact it's so old that it is the color red which is old. Anyway, this sharpener is very basic. It has no adjustments for the motor angle it is factory set, it does have the swivel chain Vise with degree markings like all sharpeners have. It works fine. I was thinking about buying a new USG sharpener and I understand that they have more adjustments, one for the motor angle, and also a B degree adjustment underneath the chain Vise, there is a degree marking that you can slide that Vise in and out for some reason. If all I'm using that to do is sharpen chainsaw chains, what is the purpose of that sliding part underneath the Vise which they denote as being letter B in the chart? Keeping in mind my sharpener that I have now has no sliding action at the bottom it is stationary. What actually happens when you slide the adjustable B scale in or out to do one side or the other on these USG sharpeners?
