Spring-Winding Arbor Size Calculator

[Dr.Al]

Hi all,

I've got quite a few random home-made tools on my website, and quite a few that I haven't got as far as writing about on the website (hopefully I'll get there soon). However, as a new forum member, I thought I'd post a new tool I've just added that others might find useful.

It's a calculator primarily intended for working out the right arbor size to use when winding a spring out of music wire on the lathe. The calculator is written entirely in javascript so runs in a web browser - nothing to install or download. If you really want to use it off-line, then Google Chrome (and probably other browsers) offer a save-as "Web Page, Complete" option and if you open the resulting file it'll work without an internet connection (as will all the other calculators on the site).
