Another member suggested I post this video on AS. It's not exactly on-topic for a typical AS forum, but there may be somebody here with one of these old blades hanging on their wall who decides to put a file to it. Although the video focuses on a small one-person saw, the techniques are pretty much universal for jointing, swaging, and setting any size crosscut saw. You'll have to pause it along the way to read all the comments, as YouTube puts a time limit on their videos. Enjoy.
