Clock (Dual Ulysse Escapement)
thingiverse
I decided to convert TheGoofy's excellent clock (https://www.thingiverse.com/thing:328569) to one using a dual ulysse escapement. Designed by Ludwig Oeschlin, it is a modern take on Breguet's natural escapement. The promised gain in efficiency by virtue of its use of radial thrust is somewhat offset by the need to overcome the rotational inertia of two escape wheels rather than one. Ulysse Nardin minimized this problem trhough the use of silicone parts. I just made the wheels extra thin. Though I consider this a remix of TheGoofy's design, I ended up making all of the parts from scratch (though I suppose the pulley and weight carrier carry over). The frame ended up a bit larger but flatter. I also decided to toss in a differential winding drum. The clock seems to run quite well on 1.9kg of weight (though individual results will vary) for about six hours (with pulley) Non-printed materials include: 2mm x 16mm dowel pins 2mm x 34mm shafts 3mm x 34mm shaft 550 cord guts or any kind of thin cordage 1.75mm filament strips See it in action: https://www.youtube.com/watch?v=CfXuEa-WGOI See the assembly: https://www.youtube.com/watch?v=NLQmyOB7T1M
