Daniels Double Remontoir Tourbillon Escapement

The Daniels Double Remontoir Tourbillon Escapement (what a mouthful):\nSee it in action: https://www.youtube.com/watch?v=sMMgvg5vobU\nThis watch escapement model is based on George Daniels' design, which incorporates Breguet's natural escapement concept ingeniously utilized by Derek Pratt. It couples the Swiss lever's benefits with those of the detent escapement while eliminating each design's weaknesses. The potential added efficiency and accuracy are almost wholly negated by the mechanical complexity. Its visual symmetry coupled with its intentionally asymmetric tick makes it more appealing, necessitating a double four second remontoir. Even though impressive tourbillon designs exist that form whole clocks (http://www.thingiverse.com/thing:1249221) or rotate in multiple axes (http://www.thingiverse.com/thing:1624844), I believe mine is the most needlessly mechanically convoluted single axis tourbillon on thingiverse!\nThis design is not a 100% "just hit print" model. The uploaded files require several improvements:\nA weight drum - It is currently hand powered\nA counterweight - It is by no means balanced at present, and taping on coins as I have done is far from elegant.\nOverall QA/QC - Most of my 3d design work occurs after a long day of work while sipping Ardbeg and blasting Postmodern Jukebox. As a consequence, there might be a few screw-ups, most notably the lack of a hole to mount the balance spring (I'm sure that there are others, and I really hope I uploaded all of the right parts).\nAside from the aforementioned screw-ups, be mindful that the pallets and remontoir fork are intentionally oversized. They require a little bit of sanding and trimming to work properly.\nI will be in the field for a while, so I'm not entirely sure how soon I will be able to do said QA/QC. I also plan to make a separate frame assembly for a non-tourbillon, non-remontoir version for easier printing/assembly/calibration.\nUPDATE : 25OCT16 I added some "making of" photos. I hope they help anyone wishing to assemble this. \nPrint Settings\nPrinter: Reach 3D\nSupports: No\nResolution: .245\nInfill: 30\nNotes: I printed everything at 30% save for the balance wheel which I printed at 90%. The whole thing is Inland natural PETG. I designed this so that supports are not needed.
