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?
