Balancing Torsion Springs

Q: What is the correct procedure to balance torsion springs AND counter-balance the weight of the door.

I'm spending waaaay too much time winding, unwinding, winding, unwinding the torsion springs on my 425lb 16' x 7' garage door. I can't keep the torque in balance between the springs.

I followed the demonstrations in various YouTube videos exactly: I tighten the set screws after I've cranked the springs to the set number of turns, then release the locking-pliers that keep the shaft from turning. But each time, the left-side of the door lifts up and jambs the bottom-right roller in its track. This happens every... single... time.

My intuition tells me I'm over-winding the springs. Fine. I unwind both springs then wind and tighten in 5 turn increments. Excruciating. When I approach the "set number of turns", I stop and check the weight of the door. It's still to heavy, so I add two more turns and check again. Still too heavy. So I add two more turns and... sproing! ...the left-side of the door lifts up and jambs the bottom-right roller in its track. Interestingly, backing off the springs from the "set number of turns" does nothing to lower the left side of the door. I have to completely release all tension on both springs, then stand on the left-side door rib to bottom out the garage door.

What am I doing wrong?

Healed!

I figured it out!
There was absolutely nothing wrong with the procedure or the products. The problem was due a tool failure: my locking-pliers were worn out!

The procedure for winding torsion springs requires securing the shaft with a pair of locking-pliers. Turns out, my locking-pliers (that I always clamped the pliers on the left-side of the shaft) would slip on the shaft after I finished winding one spring and moved to the other. D'oh!

I purchased two shiny new 10" Vice-Grip RW pliers and chomped both on to each end of the shaft. I wound the torsion springs to the specific number of turns and released the clamps--and the door works flawlessly. 

The law of parsimony strikes again! Sometimes you gotta step back from a problem to see how simple its cause.

What size springs did you put on the door?

I think there is a problem with your spring. Follow these steps to know about your springs
1- check that whether it is rusty or not
2- Check that is there is a crack in it
3- Tell me Its Type? and at what speed you are turning it
