This is the log I kept up until the weight and balance was done. It was at this point I considered the building phase complete. All that was left was testing.

I tried to log the hours as realistically as possible, leaving out the time spent setting up and testing ideas as well as study time.

It turns out that it took a little under 600 hours to complete this project. This probably could have been done in fewer calendar days, but I have a life too. Besides most of it was the dead of winter, what else to do?

Also, I bet I could do another one in less time. My wife refuses to bet me.....

Actually, many thanks must go to her as she supported me the whole time and even helped when I needed more hands.
