SOT: Spring for refinished chair
BillGill
spring for the rocker mechanism. It is very simple, just an extension
spring about 5 inches long and 1 1/4 inch in diameter. At least that is
the one I have in there now. But it isn't nearly heavy enough. When
you start to tip back it goes all the way with just a little force.
I have looked and looked and can't find anything any heavier. Does any
body know where I can find something like that?
Thanks,
Bill

line. You know the length and diameter of the spring. Is there anyway that
you could mount a larger spring in its place?
Anyway, when I was building some things tht needed springs, I just consulted
the catalog. There is an incredible variety of strengths and sizes. Or
call a spring supply house and talk to somebody. Or ask on line.
Remember, you are not looking for a chair part. You are looking for a
spring. Consult the spring guys.

Personally, I'd ask this question in rec.crafts.metalworking as there are
some spring guys there and/or spring manufacturing guys there.

<bill...@cox.net> scrawled the following:
Call the spring shop nearest you to see if they do this type. If so,
take the chair and spring down and have them find one which works.
The ones I recall on my grandfather's old office chairs were thick
suckahs, maybe 3/16-1/4" steel, a couple inches in diameter, and a few
inches long, tapered. Trick lookin' to a kid. But they were all
compression springs, not extension. I've never seen the style you
described.
Or call these guys. Give them the brand/age of the chair you want to
repair. They might have one in stock. http://www.centuryspring.com/

.... note their listing of companies on the Web. http://www.leggett.com/links.htm
One of these companies should have what you need.

======================================
First you are going to need some physical information.
1) Spring ID & OD. (This will also give you the wire diameter)
2) Free length.
3) Extended length.
4) Number of turns.
5) End terminations.
6) Any physical space limitations such as max/min spring diameter,
min/max working length.
Armed with this information, you can start with an office furniture
hardware supplier or plan "B" would be to contact a spring distributor
or maniufacturer.
It's been a long time since I designed springs and I've forgotten how
to determine spring constants (K), but you need to know that spring
measurements are all interdependant so they need to be accurate.
If you have a digital camera, take some pictures which may be useful
to the supplier.
Good luck.
