Bigger experimental Pad made because a friend Steve put the idea back into my head. He said why not make something to link two brooms together when sweeping, I had it planned out to make a device to attach to each persons broom to link them together, but it just will not work. The different angles,speed that sweepers use does not make this work. Too large of a risk of burning the rock. So I just decided to double the width of the pad and believe it or not it works! I don't expect this experiment to take off but if you don't try something you will never know. If you happen to have an idea on a broom head design I can make it for you and I might have already made one to tell you how it has worked for the sweepers.
