First I drove 3 wedges into the end of the log as shown. I started at the fat end because I figured I would beat up the tough job while I had the most energy. Anyway I put the pint glass in front of the log to give a size scale of the tree i was working on. The hardest part was getting them to take purchase in the log but once they were good and stuck into the wood it was easy to split it a fair distance down its length.
Next take a couple wedges and put them in the crack that has formed and drive them in to spread the crack even further
Now that you are working the crack further down the log the end should have opened up enough that you can remove the original three wedges and use them to split the log further. Continue opening the log and taking the earlier wedges out and moving down the log. It is helpful to take a piece of wood and jam it in the opening at the end of the log to keep it open so the wedges will come out more freely.
Work you way down the log until you reach the other end. At this point you may have some fibers still holding it together so while it is still propped open with the last few wedges and the blocks of wood at the end run your chainsaw down the middle and sever and remaining wood fibers holding the to halves together. At this point you can separate the two halves and sit back and pat yourself on the back for being so darn clever and resourceful.
On last picture showing my ear protection on the logs for size perspective.
All that's left is to mill it up with my chainsaw.
