I am in Huntsville in North Alabama. Found out there are a few guys at my office that o wood working, and one works with hickory. He suggested I obtain a block of close straight grain hickory and store it by the car for a few months so it will acclimate to the humidity. Then he can make a replacement spoke at his shop and install in one day. I may try that. I would have to cut all the bolts off since they are peened. Not sure if I can reuse them or find replacements.
