Making small tension springs

Hi,

I will need to make or buy a few small tension springs of around (I'm
guessing) an inch long by 1/4 diameter in something like 16 gauge
wire. My question is : does anyone know a good web or paper resource
to help design springs, ideally with info on how to make them as
well ? I also need to know a place to buy spring steel in small
diameters or failing all that, a good source of supply for small
quantities of springs would do instead </cheating>.

Many thanks,

Mike

Mike, you want "Spring Design and Manufacture" by Tubal Cain. 5.56 +
postage from Amazon - it's a bargain. There are plenty of web resources
out there to do the design calculations online, just google for Spring
Calculator.

For supplies of the spring material, here's the list I've collected so
far of piano wire suppliers:

Hope this helps.

That will be a very stiff spring with 16 gauge on a 1/4" diameter.
Follow Duncans link for the calculator, and google for 'piano wire'

Mike,
Local company to me at Nottingham, Kato-Entex do nothing but make and sell springs.
They have a trade counter for callers run by a very nice and knowledgeable lady who often
gives you a couple of springs if you need to trial anything.

Here's a site to look at before you buy books:

Re: Making small tension springs

That's a useful link, but a caveat: A lot of so called 'piano wire' in
model shops is NOT these days. I use a fair bit on models etc and it's
getting much more difficult to get the real stuff. It is often some
soft crap with a ground!! finish, it can't be heat-treated usefully
and it cracks if you try to bend it. The only 100% reliable source is
the American 'music wire' which is available from many of the model
shops listed. It comes in inch sizes not SWG and is not quite as
bright as our old PW, but is 'good' material.

Re: Making small tension springs

Thanks for all the replies, I'll try to get hold of the book from
Amazon. The springs _are_ quite stiff because they're the suspension
for some trailing link oleos I'm making for a model plane.

Cheers,

Mike
