Tips and Tricks

Why these links?

With Google and other search engines available, what is the point of this page of links? While searching the Internet is certainly worthwhile, sometimes a search returns too much information; for example, if you get a list of hundreds of metals suppliers, how do you know which ones cater to hobbyists, and which ones require you to buy by the ton? The links on these pages are based on discussions and recommendations from various machinist groups and forums on the Internet. Of course this does not mean that in all cases the information or vendors in these links are reliable, but it does mean that the links have passed a basic test of usefulness. As always, take all the information you find here with a grain of salt, and always use your best judgment in evaluating and using this information.

In short, I have done my best to act as a good editor - to sift through the many links to a topic in order to select those which are most useful and most informative. This page will always be a work in progress, so if you see something missing on this visit, you may find it on your next visit. And by all means, please use the comments to suggest links.


  • I am not affiliated with any of the vendors listed here. I do not vouch for or guarantee any of the information listed here.

  • Where a link is followed by information is quotes, that information is taken from the relevant web page and represent the web owners opinion of themselves.

  • Some links on this page may apply to multiple categories. In such cases, the link is put under one "primary" category. It is recommend that you use the page search function of your browser to search this page for relevant terms.

Why one big page?

You may be asking yourself, why is all this stuff on one big web page, instead of multiple web pages - one for each category. The reason I did it this way is so that you can use the search function of your web browser to search for specific terms in all of the categories at once.

About dead links

In some cases I have found useful links which point to web pages that no longer exist. In such cases, it is sometimes still possible to find the (still useful) information on various archive sites. When a link on this page is known to be dead, the original link is flagged as a dead link, and an archive link is also shown. For more information of finding archived links, look here:

1. Google cache

Google stores cache copies of many web pages, You can access these pages by prefacing the link with

For example, to view the cache copy of use

2. Internet Archive: Wayback Machine

The Wayback Machine store multiple snapshots of web pages from 1996 to a few month ago.

A quick and easy way to use these capabilities is to install the CacheIt! extension for the Firefox web browser (there may be similar extensions for other browsers, but I have not researched this).

3. There are other options available, but I have found the 1. and 2. above most useful.
