time to buy a sharpener and setter(?)

[doc henderson]

the higher voltage pulls less amps through the wire and I believe the windings in the motor.  cooler and maybe the motor last longer.   I do not think there is energy savings.  Watts = volts x amps.  for the same watts, increased (2x) volts means less amps (half) and less heat in the wire.

the 110 V can be moved anywhere, but not 220.  so, wanting it easy to use elsewhere, with a common household plug, would be the only advantage of the 110.

I sharpen blades for others. I have 2 CBN wheels,  WM 7/39T and the WM 10. I sharpen all blades that come my way with those 2 wheels.

What other profiles of blades do you sharpen with the 7/39 wheel?  I was comparing the profiles of the 7/39 to the 7/34 the other day and wondering if it would cause too much wear on the 7/39 to sharpen some of those blades.

There is a lot of metal present on the back of a 7/34 that is not there in a 7/39.5 Probably several medium/light grinds to change it. I wouldnt try it with one. If youre careful it might be worth it in terms of recovering cost of 7/34 blades vs. wear on the 7/39.5 cbn wheel.
