MEASUREMENT OF TORSION SPRING

If possible, print this guide. With this paper and a centimeter, go to the (garage) door. Complete all 4 steps so that you can tell us the results of the measurements.

Step 1:

Measure 20 threads at the break. Write down how many millimeters you measured.
Do not round the measured number! Neither up nor down, because it might be an American size spring. In other words, it is not certain that a round number will come out during the measurement.
From this number, we will be able to calculate the thickness of the spring wire very precisely!

Step 2:

Count how many threads/rings the entire spring consists of. Write down the piece number.
From this, we can calculate the length of the spring very precisely.
NEVER add the ends (loop, cone) to the length of the spring!
We only count the rows/circles next to each other.

Step 3:

Measure the outside diameter. Write down how many millimeters. (Do not round the measured number! Neither up nor down, because it may be an American sized spring. In other words, it is not certain that a round number will come out when measuring.)

Step 4:

Check your spring at the break. Compare with the pictures. Write down whether it winds to the left or to the right spring.

If you get stuck anywhere during the measurement or have a question, write an e-mail below rather than you should go to the gate again.
