# TIME2 Assembly Guide Build the TIME2 weight\-driven pendulum clock step by step By Digital Urban Topic: Home & DIY [Open the interactive Jig](https://ask.jig.com/j/HmqXxvaqbUxO) ## Guide ### 1. TIME2 Assembly Guide TIME2 is a 3D\-printed clock driven by a falling 2\.5 kg weight and timed by a pendulum that swings once a second\. The printed parts wait on the bench; the back plate is already screwed level to its wooden board\. Tap any part to see its name\. Small screws and nuts: keep them away from little children\. Nothing is glued, so every part can come apart again\. ### 2. 1 · The Going Train The going train is the row of wheels that carries the drive along the clock\. Push the third, fourth and escape wheels into their holes in the back plate\. Each turns on a 60 mm carbon rod called an arbor\. The escape wheel, with its sharp teeth, is the one that ticks\. Clean every hole first with a 3 mm drill turned by hand, so each arbor spins freely\. ### 3. 1 · The Three Cocks A cock is a bracket that holds the front end of an arbor\. Fit the three cocks over the wheels and screw them to the back plate with M4 × 8 screws\. Turn the third wheel by hand: all three should turn together\. ### 4. 2 · Anchor and Crutch The anchor is the curved arm that lets the escape wheel move on one tooth at a time\. Fix it to the back plate with an M4 screw through its bearing, so its two tips, the pallets, sit over the escape wheel teeth\. The crutch hanging below it will hold the pendulum\. ### 5. 3–4 · Centre Wheel and Great Wheel Hold the 120\-tooth centre wheel and the great wheel in place\. The great wheel carries the barrel, the drum the weight line winds on, and six springy clicks that let it wind one way only\. The centre wheel turns once an hour and will carry the minute hand\. ### 6. 3–4 · The Front Frame Lower the front frame over both arbors and fix it with two M4 × 8 screws\. Turn the centre wheel by hand: the third, fourth and escape wheels should all follow freely\. ### 7. 5 · Dial and Hands Fit the dial with an M4 screw into the front frame, then press the hour hand and the minute hand onto the centre arbor\. The minute hand grips by friction, so you can set the time while the clock runs\. ### 8. 7 · The Pendulum Push the top of the beech pendulum rod into the crutch and lock it with the crutch screw\. The bob, a 90 mm disc, slides on the rod: raise it to make the clock gain, lower it to make it lose\. ### 9. 6 · The Weight Screw the lid fully onto the weight shell with the 2\.5 kg dumbbell inside, then hook it onto the line from the barrel\. The line falls from the left of the barrel, seen from the front\. The thread carries the whole weight, so screw the lid all the way home\. ### 10. 8 · Wind It and Start It Put the key on the winding square below the hands and turn it clockwise: about 14 turns lift the weight 0\.95 m, enough for about three days\. Take the key off, give the pendulum a small swing and listen for an even tick, tock\. If tick and tock are uneven, slide the crutch a little along the anchor hub\.
