how can i make a spring
(1/5) > >>
picclock:
Hi I need a compression spring of certain dimensions (1/4" od, 0.5mm wire , 1.25" long). The spring will only be compressed by about 1/4" so I'm thinking the easiest way to get something in this ball park is to wind it myself. I'm in the UK so I'm thinking I need a supplier of small amount of spring wire so I can set it up on the lathe and make it. 

So this is really a fishing exhibition to see if anyone here has made springs, what the snags are and who are the best suppliers of raw materials.

Hope this makes sense

Best Regards

i just made 2 springs about that size, i used guitar strings. you  can get them in different sizes,and they  are also spring steel. if you google making small springs there is a good site that tells how. i am at work so do not have the site. just made one for my farm boy hit and miss and i came out real good, but there are some things  you need to follow  so you do not get hurt and they will need to be annelled.i will look up the site when i get home tonight. good luck. jonesie

 I just learned a few thing about making torsion spring, haven't tried compression yet, the links below were helpful.  Some people say the term  music wire doesn't mean it's the same as music wire I don't know,  the stuff I bought was 1080 carbon steel,  also know as music wire,  see the last link, scroll about half way down, it's a US distributor I just added it for reference.
 I heated my springs to 450F  for 30 minutes in a toaster oven,  they came out fine.

Picclock..

Check out your local model shop for piano wire...
Commonly used to make sprung undercarriage for model aircraft..(not the size you need you understand...)



They may have the size you need which is approximately 24swg..(0.56mm)
Deko:
They may be a bit too small for what you need, but a good source of small compression springs are the retractable type ballpoint pens.

Cheers Dek.
