Axe Jig SVA-170(60491)AXES AND HATCHETSFits axes up to 170 mm (6¾").Larger axes are ground without a jig andsupported on the Universal Support.(page 42).Positioning of MachineGrinding direction:Towards the edge.DesignThe jig comprises a clamp with a rubber lined, wedgeshaped stop, which holds the axe in a fixed position towardsthe grindstone. The clamp works on the UniversalSupport, on which it slides across the stone.The jig is designed so that the rotation of the stone pressesthe axe firmly into the jig. You only need to hold and guidethe axe with your hands. This jig only works with the stonerunning towards the edge. If necessary, the honing wheelcan be removed to allow clearance for the axe handle.63RTD10000743AA

Place the axe into the jig. Setthe edge angle by adjusting theUniversal Support. Either at theoriginal angle using the MarkerMethod or at a new angle usingthe AngleMaster WM-200.Press with your palm on theaxe, close to the stone. The axewill automatically be pressed upagainst the stop in the jig andthe grinding is most efficient.Follow the shape of the edge(straight or curved) duringgrinding by raising or loweringthe handle. Let the jig slide sidewayson the Universal Supportso that the stone wears evenly.Edge AngleThe edge angle of a carpenters axe or hatchet should be 25–30°, depending on the hardnessof the wood. Grind the edge with a smaller bevel angle on the side towards the woodthan on the other side. This longer bevel gives you a good support towards the wood. Also,as the axe works closer to the surface of the wood, the cutting will be more effective andeasier to control.A felling axe and a hunting axe must have a larger edge angle, 30–40°, so that the edge ismore durable. Round off the heals of the bevels and the axe cuts more easily. This is doneby lowering the Universal Support and grinding in two steps.Put a longer bevel on the woodsideon a carpenter axe.A felling axe should have anedge angle () of 30–40°. Roundoff the heals and the axe cutsmore easily.You can set and measurethe edge angle with theAngleMaster WM-200.Honing and polishing the bevelson the leather honing wheelmakes the edge cut more easilyand the sharpness will staylonger. Always hone away fromthe edge.64
