Description

A fully mechanical bilateral letter scale, made in original Technic parts, with dials from 0 to 175gr, a perfect gift for antique objects enthusiasts or to decorate a desk.

How it works ?

This machine is used for weighing letters or small objects, inspired by Columbus Maul scales. It rely only on mechanical components, with connecting rods, levers, dials and counterweights.

The upper tray is connected to each pendulum side with connecting rods, which share a coaxial rotation axle. When weight is applied, the two pendulum sides move apart, the greater the weight is. One pendulum side holds the cursors on it, the other holds the dials.

The bottom cursor indicates the weight from 0 to 80gr. It is placed further from the center of rotation of the two pendulum sides, and with an angle between the connecting rod and the pendulum closer to 90°, which makes the measurement more sensitive and linear.

The upper cursor displays the weight from 70 to 175gr, with the same functioning as the previous dial, but at a less distance and an acute angle between the rods and the pendulum. This causes less displacement of the cursor as the weight increases, allowing a non-linear scale and a reading of a greater weight.

This combination of functioning and dials enables a fine reading of the weight on the bottom cursor, and a rough reading of larger weights on the other cursor, while keeping the symmetry of the scale.
