As for safety, though, I am really sure on this one.
"if the round is elevated , and a glancing blow is struck , the higher it is off the ground the greater the possibility of injury. if the round is sitting on the ground, the blade of the maul will hit the ground further away from the swinger. i would suggest to anyone just getting the hang of it to start on the ground first to get the feel of it , then maybe elevate, but not very high. its just safer to leave the round on the ground." On the contrary, if you swing at an elevated object, at point of contact the maul head will be at a greater distance from your body and feet than if you are swinging further down to the ground. If you were striking at waist height, the maul head would be at the maximum distance from you, whereas if you were swinging all the way through the arc towards the ground it would be very close to you. So as a new wood splitter, I feel much SAFER swinging at wood that is at a greater distance from my toes. Although oddly enough I have excellent aim thus far, and am keen on splitting wood. Hubby wants to buy a splitter and I am resisting, of course I make him do the really hard pieces. Also, on the bad back issue, you have to bend further over to swing at a lower object, so how does that help your back? Bending to pick up the pieces is not hard for me like swinging the maul, which is a real workout. (We have 8 and 12 lb. mauls.)
Well, I'm not going to argue with a physics teacher - seeing as how BOTH of my GF's parents are retired physics profs who Piled it Higer and Deeper at Oxford....
However I think you are reaching the wrong conclusion from the right starting point on your safety argument.
Yes, IF you connect with the log, the impact point will be furthest from the user if the log is on a block, BUT IMNSHO, the "good hits" aren't going to be a safety problem - the axe or maul sticks into the target and stops (or at least slows way down) The problem comes from the "bad hits" where the log or the striking tool does something you didn't want it to do.
I would argue that in every case where something goes wrong, the closer things are to the ground the safer everyone is. Some examples:
1. You missed - the tool continues the arc of the swing. The higher it is, the more likely the arc is going to go all the way around to the swinger's leg/foot.... On the ground or a short block, the arc is more likely to hit the ground first.
2. You bounced - The lower the tool is when it bounces (all else being equal) the less height it will have on the rebound, and again the more likely you are to hit the ground when the tool goes back down.
3. The log falls over - The higher the log is, the further it has to fall (so it's moving faster, and hits harder) and the greater the distance it can fall from where it started, or do extra bounces or flips to land on your anatomy. (Note that this can include splits coming off an otherwise "good hit"!)
4. A chunk of wood, a wedge, or something else goes flying - Again, all else being equal, the lower it starts from, the lower the peak of the trajectory will be, and the less distance the flying object will travel. The shorter the distance travelled, the less likely you are to hit something just because of lower range. Also if you DO get hit, the lower on your body the impact happens, the less likely it is to do serious damage. (Look at the way you are built - the more fragile bits (face) are higher, but you tend to wear heavier clothing (PPE) on your lower body.
There are *NO* perfect safety solutions, but I think the odds favor fewer problems with the "target" on the ground or a short block than on a tall one.
Tell me what kind of accident you are going to have, I'll tell you what the best safety gear is to be wearing for it....
