What would be a sturdy design for a splitting/cleaving break? (to help hold a log or portion thereof so you can keep reducing it/riving into smaller pieces). Usually what I do in the driveway is wedge sections in the pile. That is not a good way and things move too much. I get things done, but the efficiency isn't as good as I want. Personally, I'd like to design something out of scrap steel so it doesn't take up as much room. I live in town and can't dedicate an area like J. Alexander or other green woodworking folks do. Ideally, it would be cool to bolt it together and be able to store it until needed. I really can't go with something that looks like a pile of logs though.

Any thoughts?
