Claim 9:
10. The mini-concrete trowel attachment assembly according to claim 9, wherein each of the second upper and lower fastening clip members of each of the at least a pair of semi-circular free-wheeling bearing cover guide ring members being attached to and radially extending from each of the at least a pair of semi-circular free-wheeling bearing cover guide ring members at semi-circular top and bottom outer end portions, and semi-circular top and bottom inner end portions of each of the upper and lower spaced apart clip members, a semi-circular outer end tapered portion connected between the semi-circular top and bottom outer end portions and the semi-circular top and bottom inner end portions of each of the at least a pair of free-wheeling bearing cover guide ring members, and the semi-circular top and bottom outer end portions and the semi-circular top and bottom inner end portions of each of the at least a pair of semi-circular free-wheeling bearing cover guide ring members having a radially extending latching fastener including a bead member formed thereon;
a fastening cavity is disposed in a bottom radial end portion below the top radial end portion and above the bottom radial end portion of the first upper and lower fastening clip members, and the semi-circular outer tapered end of each of the at least a pair of semi-circular free-wheeling bearing cover guide ring members having an inner tapered end portion that aligns with and spaced from the outer tapered end portion of each of the first upper and lower fastening clip members at each of the top and bottom radial end portions thereof, and having a clearance space formed therebetween; and
wherein the second upper and lower spaced apart clip members of each of the at least a pair of semi-circular free-wheeling bearing cover guide ring members being received over the outer tapered portion of the top and bottom radial end portions of each of the first upper and lower fastening clip members with each of the fastening bead members being disposed within each of the fastening cavities disposed below the top radial portion and above the bottom radial portion of each of the first upper and lower fastening clip members for allowing the rear inner face surface of each of the at least a pair of semi-circular free-wheeling bearing cover guide ring members to enclose the front outer face surface and the self-lubricating bearing rail and spacer member of each of the plurality of spaced apart non-rotating arm members to engage and move along each of the self-lubricating bearing rail and spacer members when a prime mover rotates the rotary disk with the plurality of replacement finishing blades for smoothly finishing a viscous material surface.
