Unit for powered wind/unwind of duct rodders

A method of assisting winding and unwinding of a duct rodder unit comprising a stand and rotatable cage or reel for coiled duct rodding or other conduit comprising:

• a. releasably mounting a hand portable frame to a stand of a duct rodder unit rotatable cage or reel for coiled duct rod or other conduit, wherein the hand portable frame has perimeter dimensions small enough for a user to carry the hand portable plate and comprises:
• i. a drive wheel;
• ii. an adjustable pinching wheel that is adjustable as far as closeness to the drive wheel;
• iii. a mounting interface adapted for selective releasable mounting to a stand of a rotatable cage or reel for duct rodding or other conduit;
• iv. a guide member on the portable frame upstream of the drive wheel configured to guide duct rodding to the drive wheel;
• v. a guide member on the portable frame downstream of the drive wheel to guide duct rodding from the drive wheel and frame;
• and
• vi. the drive wheel comprises a radially compressible body;
• b. pinching the duct rodding or other conduit between the drive wheel and the adjustable pinching wheel;
• and
• c. rotating the drive wheel with a detachable battery powered drill or rotary tool, wherein the direction of rotation of the drill or rotary tool unwinds or winds the duct rodding or other conduit from or to the duct rodder unit.

A system for power assist of unwinding and winding of duct rodding or other conduit from a stand and rotatable cage or reel for coiled duct rodding or other conduit comprising:

• a. an assembly adapted for selectively removably clamping or affixing to a stand of a duct rodder rotatable cage or reel for coiled duct rodding or other conduit, the assembly having perimeter dimensions small enough for a user to carry the hand portable plate comprising:
• i. a hand portable frame including a mounting interface configured for removably mounting to a stand of a duct rodder cage or reel for coiled duct rodding or other conduit;
• ii. a drive wheel rotatably mounted on the portable frame and having a drive axle adapted for selective releasable operative engagement to rotary output of a battery powered drill or rotary tool, and a radially compressible body with an outer perimeter surface with a width effective to frictionally engage and convey duct rodding or other conduit upon rotation of the drive wheel without damaging the duct rodding or other conduit;
• iii. a guide member on the portable frame upstream of the drive wheel configured to guide duct rodding to the drive wheel;
• and
• iv. a guide member on the portable frame downstream of the drive wheel to guide duct rodding from the drive wheel and frame.
