one I had to go overtime for, because it was my first time attempting to S.N.O.T. (bad call on my part) and it was giving me trouble, plus I figured as long as I was going overtime, might as well dig for parts. Overall, took me approximately fifteen minutes instead of five.
On the other hand...
I also tacked on a MUCH better engine bit, but didn't do it until after I took pics. Perhaps you guys will see it eventually.
