Making tools, like a Monkey!

In the ongoing saga of DIY Subaru head machining, I'm getting setup to pressure test the water jackets in the heads I'm working on. I need a place to put the air pressure and gauge on and there's this handy little plug in the water jacket. However, it requires an odd-sized metric wrench which I don't have.. so I made one (scrap steel rod, bench grinder, calipers and torch for bending. Fun fun!
