I finally put all the pieces together yesterday and it was a little like magic! Everything fit and worked and the fixture seems more or less ready to go. So WTF is it, Ezra!? Well, it's a clamping fixture for making picture frames. Though, the truth is that I got more carried away by the design of the fixture itself that I completely lost track of any sense of urgency around actually making any picture frames! I guess the truth is that I've always been a bit more interested in the tools that make the things than I am in the things themselves. SO, now it's time to try to get my head back into the space it was in at the start, when the idea of actually framing some of my photographs felt interesting to me. Which ones, at what size? To what end? Etc. I'm sure that once I actually get going on it, I'll get carried away and find it quite interesting.
