shearing edges 58 at one end shearing blades assembly 54 is removably mounted on hub member 60 which in turn is rigidly attached to output shaft 62 of motor 42 shearing members 54a are oriented on planes transverse to partial inner wall 38 and define a phantom circular outer boundary path 64 when rotated on shaft 62 adjustable angular shaped planar shearing member 66 is disposed adjacent to the lower end of tube member 52 and securely fastened thereto such that carbide shear edge 68 is perpendicular to phantom circular outer boundary 64 to form a confronting surface with shear blades 54a output shaft 62 is rotatably supported through partial inner wall 38 and within hole 58 of plate 56 when any of the individual shearing blades require service access is available by removing shear housing thin walled outer cover 48 by removing four bolts 50a square tube member 52 and planar member 56 from base plate 50 for quick disassembly and servicing shearing assembly the following steps are taken 3 to remove shear blades 54a remove screws 54b at this point shear blade can be cleaned and sharpened 4 to remove adjustable carbide blade 66 remove screw 66a to adjust carbide blade 66 loosen screws 66a adjust to proper clearance with shear blades 54a then tighten screws 66a adjustments can only be made when shear assembly 40 is removed as shown in fig1 motor 42 is rigidly secured to partial inner wall 38 with four nuts 50a on the opposite side the motor is a conventional ac or.
