Always striving to be unique in my creation efforts, it is often advantageous to look at the products of the giants who have paved the way before us. Still on my inspirational journey on wooden clocks, I ran across the National Watch and Clock Museum's web page on "The Beeler Escapements." These are not constructed out of wood, however the science and innovation are similar to those involved in wooden clocks.
Though the site does not give any technical details on the different escapements, they do show a little of the various visual elements each escapement offers. You can Google each escapement to get more details of each, but it is interesting to see Beeler's reproduction of the various escapements of the time.
My personal favourite, from a visual and dynamic standpoint, would have to be the Gravity Escapement.
If you're ever in the area, go see them yourself. The collection is at the National Watch and Clock Museum, 514 Poplar St., Columbia, PA 17512-2130.
