Hopefully everyone here has already heard of McMaster-Carr. They are a sort of do it yourself industrial superstore. With over 480,000 products, there is a good chance that they have what you need, if only you could find it. I know that there are some great treasures amongst those 480,000 items. I almost bought some track for a sliding door from them once, and seriously looked at some of their faucets too. If you have been brave enough to wade through all the 480,000 products and found some good ones, we want to know.
