I have one of the older metal ones, and thought I was getting another one, but it was plastic. Go to the hardware store and get some of the large round washers. The largest ones are pretty heavy and several of them glued together and then glued to the base work fine for me. I have also made my own thread quides with the washers and a knitting needle bent into the same shape as the thread holder rod. I used silicone caulk to glue the knitting needle to the base I constructed from several washers. I guess I am pretty cheap, but it is fun to make my own 'jigs'. Phyllis
