At the 9 o’clock position, place the second winding bar into the hole. Remove the bottom bar, and then unwind the spring a quarter turn at a stretch. Then, leapfrogging the winding bars with each turn.

Step 4: Detach the springs from the center bracket

Convert the measured values to a decimal (4-1/8 in. for example, 4.5 in. or 4-1/8 to 4.125 Divide the measurements by 40 and 20 to get the spring’s diameter. Here’s an example: Divide 4.50 by 20 =.225 in. Wire diameter: 9.0 divided by 40 = 0.225-in. wire diameter. Need to be measured correctly to match the results.

Step 14: Stretch the springs

Tap the winding bar

Once the spring is fully wound, tap on the winding bar to extend the spring about 1/4 inch from the center before tightening the setscrews. Turn the setscrews so that they touch the torsion tube. Next, tighten the screws one-half to three-quarters of a turn. Torsion tubes can be damaged or punctured if the screws are tightened beyond this point.
