Geezer, the same thing can be accomplished by flipping your clip cord on the machine, so there's really no need to change hand motion in the opposite direction to get the preferred strike. If your machine is running clockwise flipping the clip will make it run counter clockwise, which will be the same as if you reversed hand motion...thinking on these things too long, can start to feel like your brain is doing inter-dimensional travel. So if you come back with a beard, or end up in a place where everyone has beards...please note: I will not held liable for any damage done by your evil twin and or parallel dimensional rifts
