I came up with an idea. I can cut them into "wheels" and use them as pavers to make a patio.
(The ones in front measure 23" across.)
We've been talking about making a deck or patio behind the house, some place to have a couple of lounge chairs or a hammock. So perhaps wooden "wheel" pavers set in sand or gravel would be attractive and functional. I've decided to give it a trial go.
Step one....chainsaw the tree trunks into wheels. We're making the wheels rather thick to prevent them from warping, twisting, or cracking in half. Step two....remove the bark. Step three, set them in the shade with good air circulation and protected from the sun until its time to set them into place.
I've never tried this before nor do I know of anyone who has. All suggestions are welcome!
