Harlan,
I just used the build manual also, and like Dustin I didn't log my time either, for the same reason. I took a lot of pictures, and when time to apply for repairman's Certificate I handed the guy a thumb drive with pretty much all of them on it. He didn't need or want anything else but the FAA paperwork. He took it into his office for a little while, then came back, handed me the drive and said "good job". That was it.
