The Differences Between Ethanol and Gasoline. 1  A gallon of gasoline provides one-third more energy than a gallon of ethanol.  Blending ethanol and gasoline at a ratio of 85 percent to 15 percent (E85), the blended fuel is nearly thirty percent less powerful than pure gasoline. Ethanol is similar in acceleration, power, and cruising ability, but ethanol miles per gallon are less than pure gasoline.
A. I have been etching stainless steel for over 30 years. The etchant is ferric chloride, temp 130 Â°F. around 37 baume works best. Etch rate is about 1.25 mil per minute in an oscillating spray etch. Stainless does not pit in ferric chloride unless you rinse with water and then etch more.
Align the spinning abrasive blade with the location that you need to cut the stainless steel sink and lower the blade to the sink's surface. Slowly push the abrasive cutting wheel across the surface of the stainless steel sink, creating a score line.un the flapper wheel along the cut edge to remove the sharp edge left from the abrasive blade and dress the edge of the stainless sink. Round the edges at the end of the cuts to eliminate snag hazards when you install the cut stainless steel sink.
