Mover reel blade relief grinding device

Device for relief grinding a blade having a radially outer edge of an elongated length and first and second faces, with the spacing between the first and second faces defining a thickness, with the first and second faces extending generally radially from a center axis, comprising, in combination:

• a grinding shaft having a length at least equal to the elongated length of the radially outer edge of the blade and being parallel to and spaced from the center axis;
• a grinding wheel rotatable with and slideable on the grinding shaft;
• an annular housing rotatable about and slideably received on the grinding shaft;
• a backstop for slideable abutment with the first face of the blade;
• a guide finger for slideable abutment with the second face of the blade, with the backstop and the guide finger mounted to the housing and slideably receiving the blade therebetween with the grinding wheel grinding a relief grind surface on the radially outer edge of the blade extending at a tangent to the grinding wheel;
• and means for preventing rotation of the housing with the grinding shaft and the grinding wheel.
