[Shop-talk] De-coupling overhead door torsion spring

[Jeff Scarbrough]

You need to de-tension the spring first - the spring is trying to pick up
the door with the cable when it's down, and you would need to replace the
weight of the door with a secure fastening - I'm not sure what that would
look like, or how you would maneuver the cable from the door to the
temporary restraint.  AS for the spring, I used to be in the garage door
business.  I did this all the time.  And I have a healthy respect for that
spring - there's a lot of potential energy there that can go kinetic in the
blink of an eye.

As described elsewhere, you just use two rods...but...they have to match
the sockets very closely or they can slip out.  And you need to keep your
skull out of the way of the rods.  And even if you do it just right, you
can still get hurt.

There's no shame in calling in a professional who can let the tension off,
swap the door out, and properly re-tension it for the weight of the new
door.  And depending on the age of the springs, they could be replaced at
the same time.  They break from time to time, and that's no fun...
