This engine looks like something I might rig up. I love the wood panel tied on with plastic twine to hold the temperature gauge and the key :) Hey, if it works, that's what counts!
This is a wonderful photo but unfortunately I do not believe that it meets the criteria for "macro or close-up" set forth in the rules for these challenges so I cannot include it for consideration when I choose the winners.
I'd love to have you submit a more "macro or close-up" photo to take this one's place.
I've enjoyed seeing this one and I want as many submissions as possible so please do enter a replacement!
