The lathe and the hoped for milling machine will be just the ticket to help you recover. Ask me ...
.... having my shop and my Cub were the things that helped get me motivated to do what the docs and Em said -- recover and heal. I really was itching to get down and get stuff done .. having projects gave purpose especially since I was retired.
Enjoy the planning -- it leads to better things. Do what the docs say and you will be stronger and ready go before you know it
