Outstanding tops and a wonderful project, good for you. I've made them for my grand kids and this Christmas my grandson, age 5, was in the basement with me feeding the wood stove when he found a piece I had put in my scrap pile. It was the tenon left after I removed an ice cream scoop. It had a point on the end and immediately Jordy picked it out and said, a top. Darned if he didn't put it in with his toys and took it home. Powerful stuff really, something so simple. You never know how many hearts and minds you've touched. Good for you and please excuse a sentimental old grandpa.
