This axe looks really awesome, physics for the win.
Also, instead of using an old rubber tire, I highly recommend building a variable length, tensioning chain, much like this one: http://www.youtube.com/watch?v=wrLiSMQGHvY
Makes chopping wood so much more fun.
And then, there is also the stikkan: http://www.stikkan.com/
Perfect to hang it up next to your fireplace to do some more fine grained wood chopping, cutting larger pieces into smaller ones.
