TT Furious Tourbillon

thingiverse

6/6/20 Added new version of L1 Frame Base Bridge Main 2 STL that provides a Balance Wheel alignment slot, to make setting up the escapement easier. See section 7 in the build notes for more information. 12/2/19 Added some photos of the Arduino, stepper, and rotary encoder wiring. I bent all the pins on the Nano 90 degrees, to make them easier to access them. In some cases I soldered wires with shrink wrap covers, and others I used Arduino Breadboard Wires, that slip on pins. The ground signal between the Arduino (black) and Stepper Driver board (Orange) is soldered together. The +5V signal between the Arduino (red), Stepper Driver board (Yellow), and the rotary encoder (yellow) is also soldered together. Refer to the schematic for more information. 11/16/19 Changed screw lengths to minimize stripping screws. Posted new zip file (Thingiverse files 110519.zip) that includes updates to the following STL files: L2 Lower Body L2 Lower Body Trellis2 Base Drive Cover 11/5/19 Posted new zip file (Thingiverse files 110519.zip) that includes updates to the following STL files: Base Drive Outer Ring a and b Base Drive Plate L2 Lower Body L2 Upper Body L3 Bearing Race a and b L3 Bearing Race Lower The files include changes to make assembly easier, e.g. changing dimensions to provide more clearance and reduce the need to sand or file parts to get them to work smoothly. Also, use M2x4mm cap head screws to attach the stepper motor to the Base Drive Plate. If you use M2x6mm screws, they go through the Base Drive Plate, and rub against the L3 Bearing Race Lower part, preventing it from turning. 10/19/19 Added the 2x1mm_Bearing_Spacer.STL file. 10/3/19 The TT Furious page has been broken since I created it. In an effort to fix the problem simplified the upload by only uploading one file "TT Furious files xxxx19.zip" file instead of over 70 STL, INO, JPG, and PDF files. If this does not work, you can also download the files from: https://cults3d.com/en/3d-model/gadget/tt-furious. I modeled this design after a Jacob and Co. Twin Turbo Furious watch. I spent many hours looking at videos and images that I found on the web of the original watch. Similar to the Gyrotourbillon and the Triple Axis, I tried to make the model an accurate (scaled up) version of the original Furious tourbillon mechanism. I printed plastic screws to scale and used them as caps to cover the steel screws that actually hold it together. This is a real-time video of it, https://youtu.be/2-7S2i6AUyM Also it's quite large, with a diameter over 200mm. In this design, I've included several versions of the Balance Shaft and the Fork which will give you some alternatives to get it to tick easier. Please read the Overview in Build Notes to get a better feel for the constraints of this design.
