I have used my Ridgid drain cleaning machine, model K-380, about once a year since I bought it three years ago for my home. Somehow the clamp holding the end of the flexable steel cable came loose inside the drum while using the machine and the loose cable is bound up inside the drum and twisted. Is there an easy way to remove the cable so that I can re-clamp the end and rewind it? Right now it is a mess and I have thought about cutting off the top of the drum to remove the cable and buying a new drum Ridgid p/n 86967. I don't know if this part is still available or how much it costs.
