Mclaren Clockwork Submarines

Is it a Gormley? is it a Hirst??? No,  its just my latest motor build, it reminds me of those huge joke Zippo lighters you could buy at Blackpool back in the day. Its got a 10" expansion radius on the spring and is dangerously powerful, I was holding on to the crown gear for a test wind and I'm sure the skin will eventually grow back but I'll never play the piano again, which Isn't surprising because I couldn't before. Anyway I haven't got a clue what the hell to build to put it in,  but that's the fun of making it up as you go along.
