Adjustable Blade-Grinding Fixture
This grinding fixture is very flexible because its pivoting hardwood block lets you adjust the angle between the blade and grinding wheel, and it can handle a wide range of blade widths. The pivoting hardwood block is attached to a wood base fitted with steel end plates, as shown above. To make it, cut a slot in the top of the pivoting block to accept a length of aluminum channel. Fit this channel with various screw holes or attachments, such as the crosspiece shown, to hold each blade correctly as it’s moved back and forth across the face of the grinding wheel. Wax the channel regularly to keep it running smoothly. To provide maximum support for the blade during grinding, cut out a section of the pivoting block just in front of the grinding wheel so you can move the assembly as close to the wheel as possible.
