I just got my skiving machine, a consew dcs-s4, and I notice that if it's not sharpened frequently, the blade will pull the leather and mutilate my piece.
My questions for those experienced with this type of machine:
1) How often do you find yourself sharpening?
2) How long do you grind the blade for?
3) How hard do you press the grinder into the blade? Sparks fly all over the place when I do it - is this too hard?
I also use the sharpening rod on the inside of the wheel when I sharpen, in order to reduce burrs.
