Claim 21:
22. An improved mini-concrete trowel attachment apparatus connected to a prime mover tool according to claim 21, wherein the second upper and lower spaced apart fastening members of the unitary and annular free-wheeling cover guide ring member attaches to each of the first upper and lower fastening clip members at top and bottom radial end portions thereof, and extending radially therefrom with the outward forward end and the tapered outer portion, and a fastening surface being disposed below the top radial end portion and above the bottom radial end portion of each of the first upper and lower fastening clip members, wherein each of the second upper and lower spaced apart fastening clip members received over the outer tapered portion of the top and bottom radial portions of each of the first upper and lower fastening clip members with the fastening bead member abuts and move along the fastening surface disposed below the top radial portion and above the bottom radial portion of each of the first upper and lower fastening clip members that causes the annular rear inner face surface of the unitary and annular free-wheeling bearing cover guide ring member to engage and move along each of the self-lubricating bearing rail and spacer member of each of the plurality of spaced apart non-rotating arm members when the prime mover rotates the rotary stabilizer with the plurality of replacement blades for smoothly finishing a viscous material surface; and
the front outer face surface of each of the plurality of spaced apart non-rotating arm members having a self-lubricating bearing and spacer member that engages the second unitary and annular free-wheeling bearing cover guide ring member to allow the unitary and annular free-wheeling bearing cover guide ring member to rotate along the self-lubricating bearing and spacer member of each of the plurality of spaced apart non-rotating arm members when the first upper and lower fastening clip members of each of the at least a pair of the spaced apart non-rotary arm members, and the second upper and lower spaced apart fastening clip members of the unitary and annular free-wheeling bearing cover guide ring member are fastened together.
