All the pictures are great but this one struck me as the funniest I have seen in a while. Reminds me of an engineer friend of mine, I went over while he was building some shelves,,, I had to remind him not to give up his day job as he wasnt going to make it as a builder.
My brother and I were called into a factory for a couple of weeks to help them meet some deadlines on some conveyer machines that had to ship out right away. They needed 1" & 2" RMC run to the various motors along the contraption and there was no room for sweeps. Everything was condulets. It was wierd at first, but after we got used to it, it turned out pretty well.
I can imagine this guy was exposed somewhere to this being normal, and he's probably quite proud.
