Chainsaw Electric Start One-Way Drive 

This is a pretty simple one. Since my latest revision of my chainsaw drill-start adapter no longer freewheels within the chainsaw itself, I needed something to do the same job but outsourced to the drill. So I bought a cheap starter drive on eBay and welded a socket to it.
I was worried I cooked it during welding, but luckily after a little use it freed back up. Outside of that concern, everything went more-or-less to plan and I now have a useful tool that works as needed.
