Increase or decrease the spring tension as necessary.


You're going to get this guy hurt. You don't know what you're talking
about, and it is glaringly obvious.

Don't "wind as tight as you can"!!! He can break the spring easily
that way, or worse increase the chance of a winding bar coming out and
hurting him.

There are 28 quarter winds (4 complete spring revolutions) on a 7'
high door, you multiply door height by four to calculate the quarter
winds.

Also, don't paint the spring! The paint will cause the individual
coils to stick together, resulting in bunching and rough operation.
Besides, you can not judge tension just by looking at it.

That's even more factual than what I was going to say. Thanks! It's
amazing how many people are indifferent to, or actually enjoy the pain they
can try to impress upon others.
Even better yet, there are web sites that will help with it if one takes
a few minutes to do the research. Which I'm not interested enough to do
since I think this job should be farmed out due the the OPs initial phrasing
of the question.
It was also stupid to start another thread, which disconnected it from
all the preceding information.
