This is a pretty simple one. Since my latest revision of my chainsaw drillstart 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 moreorless to plan and I now have a useful tool that works as needed.
