Em MacIntosh
3rd Black Belt
I have a two home made makiwara. One is a phonebook wrapped in carpet and the other is a piece of ironwood with a half inch of straw on the striking surface. The latter doesn't last long. I hate the wave masters. You have to fill them with lead shavings or something to make them heavy enough to actually lay into and hit full force. From my experience, the canvas Hv. Bag with no gloves is the best. Concentrate on keeping your wrists tight. "Sugar" your knuckles a little and swell them up so they become a bit numb, then hit it full force. This forces you not to rely on wrist wraps to protect you from a bend. It also impact trains your cartilage. Problem with your knuckles getting numb is that you might overdo it. I had a six foot ceiling growing up and I managed to use the bag effectively but it was just roped between two chains and had no swivel. This reduced it's swing but kept it moving.
