The wife screamed there was a gunshot in the garage and yelled at me to
grab the grandkids and shoo them out the front door immediately.

This is what I found in the garage:

The funny thing is, we've already covered *everything* here, on
alt.home.repair; so, I have no additional questions for you guys!

I'll give Dan at DDM Garage Doors a call in the morning, and, I'll have
yet another garage door torsion spring repair under my belt.

I'll measure the springs, upgrade to heavier-duty springs (I'll aim for
around 40K cycles), order new springs, winding cones, bearings, cables,
hinges, etc. (as needed) - and I'll remove and install everything
(probably in about an hour).

Thanks to all your past advice and help - there just isn't anything
unknown about the DIY replacement of this particular garage door torsion
spring repair. (Or so I hope.)
