Links and group information

I have a small web site devoted to the happenings going on in my
shop.
What I'm looking for are web site links that I can add to my web site
that are related to the hobby of metal working be it suppliers, other
hobbyists sites, or old engine sites as in hit-n-miss engines, steam
engines, stirling engines, or toy train sites. You can visit my site
at http://www.geocities.com/miniengine and please feel free to give
me
your feedback. Also, I am looking for other online groups to join
in the field of metalworking. Thank you.
