So here's more:
• Loads and loads of high-res pictures of the the restored telescope showing fine details of its mounting, drive, and parts. Click thumbnails for large views, which you can enlarge further to full resolution. Steampunkers, eat your hearts out. Courtesy Jim Hendrickson.
• Video of the remade flyball governor in action on the Clark telescope mount. Before electricity (and especially before AC power with a 60-Hz frequency that's highly regulated), mechanics relied on governors to regulate speeds of machinery. The faster the governor spins, the more its weights swing outward by centrifugal force, thus slowing the spin back down. Such a system provides precise speed control under varying forces and loads, no electronics required.
