ABSTRACT:
A cutter subassembly for a concrete planing machine which is comprised of an elongated acrylic plastic tube on which is manually assembled a set of circular multitoothed cutting elements and annular spacers arranged in a predetermined order to provide a desired cutting configuration along a linear axis. The cutting elements and spacers are assembled in a jig which additionally permits the attachment of a retaining clip at each end for holding the cutting elements and spacers in a fixed position on the tube. A plurality of completed cutter subassemblies are mounted on the cutter shafts of a drum assembly of the planing machine. Upon rotation of the drum assembly, the acrylic tube of each cutter subassembly disintegrates, providing the needed relative radial movement or play between the cutting elements and the cutter shaft during a planing operation.
