Thing like this happen too frequently, and have happened many times to me. In an effort to thwart "owner induced errors" when I do a job, I do two things, I get a package of zip lock bags and break down the job into sub-assemblies. I start a check sheet and as I take stuff apart, I put the parts into a bag. If I am real unfamiliar with the assembly, I number the bag with the step number on the check sheet. The zip lock bag even allows you to put a photo in the bag with the parts, or write the photo number on the bag if you leave the photos in your smart phone. I even put things like broken clevis pins or stripped hardware in the bags, it helps me to remember how many pins should be put back in the assembly. Especially in a project that takes a year or better to complete.
