John, I have made a rig close to what Hank described above "The U shaped channel", with one additional item. I threaded a piece of all thread and attached it upright on one end, in the center of the "U". I then made a cleat that would slip over the all thread rod, and a wing nut on top that allowed me to tighten the "cleat against the top of the log on one end (NOTE: I added a sharpened metal point on the underside of my cleat, really a 20 penny nail, so I could hammer that point into the top bark at the end of the log before tightenening the wing-nut down. This keeps the log from rolling as I make my first slice with either the band saw or chain saw. I could then remove the log from the channel, and lay the flattened side down on my band saw table and proceed to square up the other three sides. You could add a similiar arrangement to the side of your sawhorses and hold the log vertically for slicing down one side with a chain saw. I always just tried to get one side flattened this way, then depended on my bandsaw sled to finish squaring the log. Hope this helps, and be careful!
