I met Michael Cullen here in CA, at a local wood turners demonstration. The local club had asked me to do a demo with throw tops. I had the chance to chat with Michael and show him my stuff along with the spin-tops that I had brought along with me, including a few that Alan Gray had made. He was very impressed with the tricks and the tops, as he is mainly familiar with finger tops. He let me keep one of the three tops he turned in the demo and gave the other two to the wood turners club. Great guy, great experience! Hope you get the chance to meet him Jim.
