well if you are going to carve it all....you could get a splitting maul and a splitting wedge and a couple Â*good oak wedges and split the blocks! Â*First cut in the lengths you want with a chainsaw, and then split....you can half them, then quarter the halves and go down in size and far as you want..even if you want some cut wood....if you have a bandsaw you can resaw some pretty large pieces into square stock...all this in my opinion of course! Â*:P :

I should have asked the diameter of the log?? You might only need a hammer and a froe to split into usuable chunks!
