My overhead garage doors use extension springs. I thought I might

worth.
This is strange - my conclusion is that the installation package comes
with the door (tracks, hinges, rollers, springs, etc) and that's it.
What about if you wanted to build your own door? You'd think that you
could get a kit SOMEWHERE.
It looks like I would have to buy all the parts separately - hoping that
I got ones that went with each other. And, of course, paying a
premium over what a package/kit would cost.
Frustrated and baffled,

You could go back in time and use what my granddaddy did, wire cable,
pulleys and boxes of sand and busted concrete. Lasted longer than he
did, which is more than you can say for a lot of the spring
counterbalances these days. Pure profit centers for the door
installers, they KNOW they'll be back. Not sure torsion springs would
be an improvement anyway. When they go SPROING, there's a whole lot
more energy involved.

Did he work out a way to lessen the force as the door went up?

I put hanging weights on my sectional garage doors, instead of the
extension springs that came with the kits. Part of the weight is big
steel pipe filled with scrap metal. The rest is a few feet of heavy
chain that hangs below the pipe. As the doors go up, the chain piles on
the floor.
