Its all relative, and as-cast cast iron is too soft to maintain its shape as an effective termination point. The last figure I heard for the hardness of piano wire was 45 on the Rockwell C scale. >I suggest you do some reading and get your facts straight before you >contradict the laws of nature. JD, I don't understand why you find it necessary to go after Dave in this manner. Dave P. is one of the sincere guys on this list, and I would have expected some level of diplomacy to be more appropriate. Indeed JD, I would like to suggest that you inspect a few in-service capo bars for your own edification. If its string noise you're after, as-cast capo bars are just the ticket.
