Lego Dual Balance-Wheel Verge Escapement

Explore verge escapement regulated by hairsprings, with a hands-on guide to crafting your own spring. A hairspring in watches is pinned at the center of the spiral, and at the outer extreme. Because of the two immovable end points, it doesn’t breathe concentrically. Some watch manufacturers have corrected this problem by mounting two hairsprings, each mirroring the other and averaging out any errors. In addition to the advantage of having twin hairsprings, two balance wheels means the inertia of the regulator is doubled, which promises more stable timekeeping since a body with greater inertia is more likely to keep going, regardless of shocks to the watch. But there is a downside, as extra energy required to move the second balance wheel. If you follow the steps described in the brief tutorial, on making your own hairspring, you might fail to produce a decent spring in first trial. No problem — Acrylic is thermoplastic and is capable of being repeatedly softened by heating and hardened by cooling. You can immerse a deformed spring in boiling water, take it out, straighten it and repeat the steps. Torsional constant of the 3D-printed balance spring: K = 4.65*10^-6 Newton*meter Chapters 00:14 Dual Balance Wheel: 3D-Printed Hairsprings — Top View 00:47 Dual Balance Wheel: 3D-Printed Hairsprings — Front View 01:25 Dual Balance Wheel: 3D-Printed Hairsprings — Side View 02:15 Dual Balance Wheel: One Home-Made Hairsprings and the Other, 3D-Printed — Top View 03:03 Brief Tutorial on Making a Hairspring Watch Lego Verge Escapements in action:    • Lego Verge Escapements   My sincere thanks to @davidziemkiewicz for the following tips: ”For those without 3-D printer, a strip of acrylic heat-formed into a spiral (put it in boiling water, wind it over something round and let it cool in this shape) works as a decent balance spring too.” “in my tests, 3mm wide, 1 mm thick acrylic coiled into cylindrical spring with about 2 cm diameter worked well.” #LegoEscapement #ClockEscapement #SimpleHarmonicMotion #LegoClockMechanism #MechanicalOscillator #diyphysicsclock
