How to make a mechanical watch

Mechanical watches have a complex mechanism. The simplest consist of six main components: engine, transmission mechanism of gears, regulator, dispenser, hand mechanism, the mechanism for winding the watch. To make mechanical watch independently, would require knowledge of mechanics and the ability to calculate the gear ratio of the gears and shafts.

Instruction

The most convenient for self-production are wood. Take a thick wood: maple, ash, beech. Cut it from the disks of the required thickness and impregnate them with varnish, for example, parquet.

Calculate the main transmission gear and pinion (shaft) hours, given that the second shaft makes one revolution in 1 minute, the Central shaft (minute) rotates for 1 hour. In the simplest calculation is necessary to obtain the nine main gears and three additional for the host plant.

Undercut of the workpiece in accordance with the received size. The trib ends make holes for mounting the supporting shaft of bamboo or metal.

Cut on the pinion and gear teeth by using modular milling cutters or CNC machine (if you have it there).

Carve the wood arrows, anchor fork, fork, pendulum, pulleys, weights, hand crank, dial.

Then glue the arrow to watch the wheels, put the gear on tribe. Fabricate platinum (space for installation shafts) of the same wood, drill the holes for the shafts. Make a wooden dumbbell (utilite its metal or cement from the inside).

Collect the clock, hang the pendulum, run them and adjust.

Note

The first watch is considered a sundial. They gave undoubted accuracy of the measurement, but dependent on the weather, and they could not use at night. Therefore, the ancient Greeks and Egyptians invented and built a water clock, called clepsydra. Their working principle was to efflux of water from the vessel through a calibrated bottom hole. On the vessel wall was applied time scale. It was invented many types of water clocks, devices for them. There was even water alarms.

There was also a fire watch and an hourglass. In fire watch to determine the time, or rather its period, used candles or wicks. The hourglass device consisted of a glass beaker and fine sand, rolling in through the hole.
