Hey John
I made a coupler for my coil winder from a piece of hosehold shower hose using two small stainles steel clamps. It also acts as a flexible damper. And all at no cost, As I said, sometimes you have to make do with what you have on hand. As for the Pac Ratting, you are not alone, ask my wife.
I just Goolged “Steel Shaft Couplers”, they are available on-line in more varities and sizes than the sands on the sea shore. “Grainger” sells then here in Canada, but Ithink they are Trade exclusive??? Copy and paste the following.
