Just saw that on youtube: This idea is just plain brilliant!
Making one for myself in the very near future!
Making one for myself in the very near future!


Walk into any bowling alley and they have racks for you to choose from. I have never had a problem taking one home. They are put there by others when they don't want them anymore. This is brilliant and will copy.
I found a source for a more robust sphere for this clamping setup.
I knew I had seen steel sphere's somewhere, but it took me a while to dig through all my saved links and find it.
Those steel spheres are hollow. I would expect them to dent and deform if clamped like this.
Also, the urethane in a bowling ball will make for a tighter grip when clamped in metal rings.
