Hi, I have just bought a new lathe JetJWL 1220 VS which has a 1X8inch thread, I have a Record nova G3 chuck which is 3/4x16 fixed thread which is brand new, so I bought an adapter from axminster which fits fine but am worried about the extra distance from the headstock and the extra weight, will it damage the bearings , should I get a direct threaded chuck 1x8 and sell this one. Thank you
