I'm like you Arrow, I enjoy working on things until I get frustrated, then things get crazy. My father is opposite and has the patience to see things through, even at a snails pace, under pressure and at all odds.
Dave had a much better situation as he knew that it was going to be a mess before laying a wrench to it, and had a open time table. Having no pressure is a huge deal.
Only until lately have I had the distinct oppurtunity to work on my own stuff (my old 1 ton truck) with that open time table. And things go so much more smoothly as I'm much better prepared, and when a snag occurs I drop it until I have time to research, prep and do it right. When this truck was my daily driver, I
cut a lot of corners and patched things up very poorly to get me running again. The truck still has a huge dent in the door from when I kicked it.
BTW Dave - Great work on the B21!
