HOW TO MAKE SPRINGS by Dave Silberstein


Until a few years ago, Dave Silberstein maintained a great site at EarthLink that delved into the mysteries of making springs. It was very extensive. If you needed to make a spring, his site helped you do it. He even went so far as to publish the site contents in book form at Lulu.com. Sadly, both the site and the book are no longer available because Mr. Silberstein passed away in 2012 in a car accident.

Such a valuable resource should not be lost. Fortunately, the WayBack Machine of the Internet Archive has kept an archived copy.

Here's the site map so you can get an idea of what's available and also so the search engines will pick it up.

New stuff
This is an index page that provides access to new stuff added since January, 2003, and a chronicle of updates to the main body of the site.

Here's the link to the entire website for HOW TO MAKE SPRINGS.


There is a slightly older version of the site available for download as a ZIP file.

A PDF version is hosted here.

Here's a site that describes a homemade spring coiler. And two more sites for similar tools: One, Two.

A YouTube video of a spring winder.

DI-ACRO made a spring winder that shows up on eBay once in a while. Other manufacturers have made and make spring winding tools as well.

Sean Michael Ragan has an informative spring-making site.

Tempering a spring.

Also an excellent, down-to-earth HOWTO site for spring-making is Randy Hengl's. He has an interesting approach to tempering the springs: burning them in motor oil.
