Sharpening Handbook - Calculations used for
calculating SVM Knife Projection
Because sharp enough
... usually is not.

Definitions
  1. Grindwheel Radius (GwR) = Grindwheel Diameter / 2

  2. SVM-x Knife Jig Projection = SVMxP
Assumptions
  1. USB diameter (USBD) = 12mm
    USB radius (USBR) = 6mm

  2. SVMx shaft diameter (SVMxD) = 12mm
    SVMx shaft radius (SVMxR) = 6mm
Calculations
  1. L12 = SVMxP2 + GwR2 - 2(SVMxP x GwR x cos(β + 90))

  2. L2 = SVMxR + USBD = 18mm

  3. Distance from Grindstone to USB = L1 - L2

Remember : The goal of sharpening is to produce sharp tools, and these tools can injure you if mishandled. Safety measures should be followed to protect yourself and those in your shop. Be sure to read and follow all instructions from the manufacturer, and and utilize proper safety equipment. Never consume alcohol or anything that could impair your judgement before sharpening tools, or using sharp tools. Comments can be sent via eMail to me at SharpeningHandbook@Gmail.com.
