Torsion springs? or Extension springs?
Ive only done torsion springs, and they can pack a wallup.
Id be careful with that threaded rod Elk, its pretty soft, assuming you had a 12" length or so to crank the springs , that stuff will BEND.
EDIT-( nevermind, I see that you are using the allthread to compress the spring, not as a lever...)
I used a mild steel rod, 5/8" I think, maybe 7/16" diam ( ive slept since then)
nothing to it, you just have to be careful, and aware.
I made the kids stay in the house, just in case my hand slipped and sent that steel rod boomarang style through the garage.
it was cool though, I didnt even die.

There are real dangers working with springs of this kind. I know of a guy that had to cut two of his fingers off because he got trapped and caught.
he was working restoring a garage door spring he had it extended and thought it was secured witha c clamp while positioned on a 6' step ladder.
Two of his fingers got trapped in the spring when the c-clamp let go. He had only a set of plyers and a few wrenches and a utility knife in his tool belt. He could not reach it tool box.
his only choice was to use the utility knife and cut off his fingers to free his hand. Playing around with garage door springs is not the a job for a novice.
Knowing the dangers I I was able to secure the spring using a threaded rod and thghtening the nut to draw up the tension. Unfortunately that was the easy part.
When the garage door opener did not lift the door, it jumped position in the chain. It took 3 attempts of trial and error to finally get the righ position of the chain. Eandh time it had to be removed and rotated then re-tentioned into place. This too is a dangereous proposition real easy to jam a finger in the chain and sprokets. But It id working now. fortunately the garage door opener was thermal protected and only needed to be reset It took 4 hours for what looked like a simple job. but it works and I can still count to 10 with my fingers
Agreed, garage door springs are NASTY items - you should try the ones on our double wide wooden door that are rated for 300lbs EACH.... (The biggest springs you can get in most H/W stores or Home Despot are about 100lbs each...)
I find they are easiest to work on when the door is UP as this relaxes the spring as much as it gets. If I need to put tension on the spring, I think the best technique is to use a "come-a-long" ratcheting type winch that you can really hook into the spring and the mounting points.
Like cutting wood, this is the kind of job where one shouldn't work alone, or if you must keep a phone on you to dial 911 with....
