I found those articles in HSM to be very good. Since the data is presented
in the form of nomographs, it is very easy to zero in on your specific
spring needs. I have made about 30 springs using them and have been
impressed with their accuracy. There is also a formula and chart for sizing
the mandrels for lathe winding a given diameter spring which is very good .

I bookmarked this site years ago years ago and have found it useful on
several occasions http://home.earthlink.net/~bazillion/intro.html

Best I have found on the web for spring winding.

If you have a good collection of Home Shop Machinest the May/June and
July/August '87 issues have all the tables and graphs.

If I make a helical spring out of size X music wire, of length L and
diameter D, with N number of turns, does anyone have a formula for the
spring constant? This could be in pounds per inch or any other units
you
care to give. I don't need rocket science accuracy.

Thanks,
