I am sure this has been answered quite a few times but I couldn't find anything. I have a customer with a "warped" shaft. When rolled by itself the tip stays flat and the joint end stays flat. Approx. 10" pro taper. Is there any method of straightening and if so will it last or is it a fact that once warped there is a "memory" meaning it will always go back? For this customers sake I do hope so as this is one very nice old growth tight grained shaft. Thanks Rod...
