Some of our players have serious back issues. We help them by making our own “magnetic” jacks. They also find it helpful to be able to play with a “magnetic” throwing circle.
After experimenting with a number of cool, sophisticated ideas for making a magnetic throwing circle, we found that the simplest design was the best. Simply wrap a piece of string around the circle and tie a piece of iron (like a nut) on to it. Then the circle can easily be lifted with a magnetic boule lifter.
