I have never split wood that is all the same size and rarely do I get wood that only needs to go through the 4 way once. My process goes like this: Do not split right down the center but keep the log close to your body and split off just a fraction of the larger log away from your body. The bottom outside piece will be small enough to not need resplitting in most cases. Use your left hand to keep the bigger pieces that come out the top of the wedge to prevent them from falling down to the ground. Once you hit the lever to return the ram, you use both hands to take one of the big pieces and place it on the ground by your feet. The remaining big piece you position on the splitter to run through the 4 way again. (this can all be done generally by the time the ram has fully returned. Then you just have to pick up the 1 piece you dropped by your feet and run through again. I have split close to 1500 cords with that machine and I can make pretty darn good time with it. If the round only needs to be split in 6 pieces, I can do it in 2 strokes of the machine without having to pick up and pieces to resplit. Does my method work with every log? Heck no but it works with many.
The wedge also just slips on and off so it takes seconds to take it on or off when you get knotty, twisted, or really big wood and I usually save a bunch of those to do at one time as I'm working through my pile of rounds.
I'm not trying to start a pissing contest here at all but I've seen tons and tons of videos of guys running all kinds of splitters and I think most of us in here can agree that we would work circles around many of those guys on those same machines.
