It's been a busy couple of months at the day job, but now that things are slowing down again I'm able to spend some quality time in the shop. I've set up the jig for my next personal mountain bike, an all-mountain hard tail. The first tubes have been mitered and fit. It feels good to cut the tubes by hand with files, carefully shaping each miter (or cope) until the the tubes just fall into place. What you see in the picture is a fixed head tube and bottom bracket with the seat tube and down tube held in place only by gravity.
