Well folks, for complicated builds I try to take copious amount of photos (not so easy in the heat of construction) and document major parts of the build. It’s really can be tons of additional work to perform this documentation, though. Since I mostly build traditional furniture, not so sure much of it’s going to appeal to the majority of woodworkers.
I do this for two reasons, one so I can document what process I used during construction, so I can look back at a older build to remember what the heck I did. Secondly, I use the documentation to show the ‘client’ the progression of work, although most of my ‘clients’ are family or friends. I post this information on my website.
