Abstract: Steel mill waste containing iron, iron oxides and polluting compounds are treated with a strong alkali to raise the Ph to 14 to allow more alkali to solubilize silica. The mixture of materials and silica gels is then reacted with alkaline silicic compounds and allowed to cure and form hard sedimentary rock-like materials, solidified ...

End mills are made out of either cobalt steel alloys (known as high speed steel, or HSS), or from tungsten carbide in a cobalt lattice (shortened to "carbide"). High Speed Steel (HSS): Provides good wear resistance and costs less than cobalt or carbide end mills. HSS is used for general purpose milling of both ferrous and non- ferrous materials.

The abstract steel sculpture Surf II is dedicated; it's Everett's first piece of public art. Originally located downtown on Colby Avenue, it's moved to the Port's boat launch area around 1983 where it stands today. The 40,000-pound piece stands 14 feet at its highest point and features nine finger-like pieces that jut toward the sky.
