I just got a call from someone else who has a broken rod on her Venus harp. She had contacted a number of technicians and was told there was nothing they could do. I told her she would need to send me the broken rod with the coupler so that I could probably make her a replacement rod. I need to know the diameter of the rod, the length, the threadings at both ends, and I need to be able to extract the broken piece of rod from the coupler so that I can re-use it. Any technician should be able to do that for you.
