Chopping that wood would be very primal.
A milk jug with sand would be an OK substitute for a kettle bell. The handle might not bee too comfortable but you can't beat the price.
You can build a slosh tube with about $15 worth of material from Home Depot. Look for Mark's blog entry about it or search YouTube for slosh pipe. I recommend starting with a 2" or 3" pipe no more than 8' long. They'll cut it for you. You just need to buy a cap for one end and a screw on cap for the other end and a small can of PVC pipe cement. Fill it 2/3 full of water and just walk around with it, try to lift it over your head, or do bicep curls with it.
