    My customer's 1907 Howard grand broke a wippen spring. Swapped out for now with C8, but I promised I'd investigate how to repair.
    Anyone know if these springs are available somewhere, would one of those universal Tokiwa wippens work in a piano of this age?
    Thanks!

    How about buying bg some spring wire and make your own? Check your supply house catalogs, and I think they're made by Mapes.

    Easy to make from old guitar strings.  If you do much tuning for rock/pop concerts, you're bound to find some left on stage after gigs.  Usually #13 is too stiff.  A shop that repairs & restrings guitars, mandolins, etc. probably has enough to last the rest of your career.

    Hi Scott,
    That's a double loop spring and I haven't yet found a source or substitute so I just wind my own with appropriate diameter piano wire and round nose pliers. Takes a little practice but gets easier the more you do it. Be sure to adjust the arms for reasonable tension before installing so there's less adjustment after it's assembled.

    When I make a custom spring in the shop I'll usually make a few extra. After making some it doesn't bother me to duplicate one in the field now. 

    Stay well,

    It looks like an easy spring to duplicate, Scott. I have had to make my own springs at various times, most memorably for a 1900’s Bluethner upt. I bought a spring-making tool from one of the supply houses but I found that I needed to make my own jigs more often than not.
