well, this is an accurate scale. On the scale on the left, one block down from the initial position (shown in screen shot) is 1,000lb. The current weight is set to 1,000 lb to demonstrate as such. The scale on the oposing side is 5 times stronger and subsiquently 5,000 lb is required to decrease the scale down by 1 block: procice increments measured with the tubes and the green colored cylenders atop the spring (the green part of the weight= the point of measuer. The whole device is color coded from green at 0 to red at 100 percent capacity, and to remember which side is which, the irrelivent substance of each side is either yellow for 5,000 or green for 1,000. Idk how and what this will be useful for, but enjoy!
