Joe Murray Dewey Ti Bar Ends
JOE MURRAY DEWEY TITANIUM BAR ENDSThe Dewey Titanium bar ends are a Titanium replication of the Cro-moly set described above. The cinch tube is 1 1/4" wide with a 1.2mm wall thickness. The grip tubing is made of .8mm wall thickness Titanium tubing, miter cut to fit the contour of the cinch tube, then TIG welded at the same angle, with the same bend as the Dewey Cro-Moly set. The cinch fitting is machined from Titanium rod, and TIG welded as the last welding step. The cinch assembly is then sawn through to make the clamping mechanism. The welding is done fine, clean pulsed welds, to standards we see only in American workmanship. These are manufactured by Sandvik for Murray to their specifications. The cinch bolt is chrome plated steel, threaded with 6mm x 1mm thread pitch, is 20mm long and weighs 6 1/2 grams. The Dewey Titanium set doesn't come with grip tape or any end plugs. The weight of a pair of Dewey Titanium bar ends with steel bolts is 124 grams. No longer made, we sold these for $139.99 a pair. |

In-depth Information About Metals Aluminum Aluminum is extracted electrolytically from bauxite ore. It is made by the electrolysis of aluminum oxide which is found in larger concentrations within bauxite ore. Bauxite is a mixture of the hydroxides of aluminum, together with other impurities such as oxides of iron, titanium, and silicon. Bauxite is produced by the weathering and change of aluminum silicate rocks usually found in tropical and semitropical regions where climate has produced an accelerated weathering process. Bauxite is not a rare ore and is widely available in the US, the Caribbean, and Europe. Approximately 4 pounds of read the full article... Beryllium Beryllium is a specialty metal that is steel-grey metal in color, with an extremely low density, making it very light weight. At 1.85 grams to the cubic centimeter, its density compares to that of magnesium. It is also a high strength metal, making it possible to design light weight, thin membered parts with ahigh stiffness. A column made of beryllium to support a load placed directly downward on top of it, will have a greater load carrying capacity, and be lower in weight than any other metal of equal size. Until the 1950's beryllium was used read the full article... Titanium The element titanium was discovered in 1763 by an English cleric, William Gregor who was an amateur chemist with an inquiring mind. It was in the black sands of Cornwall that he discovered the new element that had up to that time, attracted little scientific interest. A few years later, an Austrian, Klaproth, extracted the same element from an ore widely known as "rutile", which is a mineral consisting of titanium dioxide (one titanium atom, two oxygen atoms), that is a reddish-brown substance with a slight metallic luster. While rutile is the highest grade read the full article... Metallurgic Hardness Testing There are three types of tests used with accuracy by the metals industry,they are the Brinell hardness test, the Rockwell hardness test, and the Vickers hardness test. Hardness is the property of a metal which gives it the ability to resist being permanently deformed (bent, broken, or have its shape changed), when a load is applied. The greater the hardness of the metal, the greater resistance it has to deformation. Since the definitions of metallurgic ultimate strength and hardness are rather similar, it can generally be assumed read the full article... |
