Biggest disappointment so far has been the jig I built for cutting miters. It is off in some way so that the four sides of the frame just don't close up. I did learn that narrow kerf blades can deflect, which was one of the problems. Learned that wide kerf blades are much less likely to deflect, and kerf width needs to be considered in some cases.
I also learned that to make picture frames, you really need a miter trimmer (Lion type). Got a Griz trimmer and voila, perfect miters. Learned once again, that sometimes you just have to have a specific tool to get the result you want. Precision isn't as exacting for woodworking in general, but sometimes, it is everything.
This was an interesting question because there have been so many frustrating experiments, and so many lessons. Looking forward to others' responses.
