I've just installed a new door on my garage this weekend. Part of the
instructions are written for the torsion springs. It does say that you
need two _solid_ steel bars to accomplish the task of tightening the
new springs. The instructions also warn against removing an
existing torsion spring mechanism. I'm not sure what the difference
is, but they do warn that death is a possible result if you aren't
careful.
The springs on my door are extension springs with pullys, so I didn't
pay too much attention to the explanation of the tightening procedure.
I could fax you the page(s) if you'd like.
