Fast Feather Bar Ends
FAST FEATHER TITANIUM BAR ENDSFast Feather's bar ends are an L-bend style, made of Ti 3Al-2.5V tubing. The cinch assembly is made from 1.2mm wall thickness tubing cut to make a 1 1/4" width on the handlebar. The cinch fitting is amchined from Titanium 6-4 rod. It's turned on a lathe to reduce and round the center and radius the rear corner. The fitting piece is drilled and tapped for the necessary 6mm by 1mm pitch threads. The Fast Feather bar ends come with a machined from Ti 6Al-4V rod cinch bolt that is 20mm long, weighs 3 grams, and has a 6mm hex fitting. The grip tubing is also made with a 1.2mm wall thickness, and has an overal length of 8 inches. The tubing is miter cut where it joins the cinch assembly, so it solidly contours the cinch roundness, then the two pieces are TIG welded together. The grip is welded so it leaves the cinch assembly with no upward angle, while introducing a 7 degree angle inward toward the front wheel. At 3 1/2" from the cinch tube the secondary bend adds 65 more degrees in inward angle toward the front wheel in making 4 1/2" long secondary grip section, which also rises at a 9 degree angle. Once the Grip tubing has been welded, the cinch fitting is welded in place under the cinch tube, which is then sawn through horizontally to create the cinch assembly. The Fast Feather bar ends come with two Black press-in plastic caps installed in the end of the grip tube. Two more to fit in the end of the handlebar are not provided. The Titanium metal after manufacture is given a high polished finish with a light abrasive on a polishing wheel. This is the only Titanium bar end that has this mirror-like finish. The pair of the Fast Feather bar ends, with the Ti bolts and end plugs weigh 164.5 grams. These bar ends ceased to be available in August of 1994. Bob Anderson the owner of Fast Feather, having a well known cloud on his character in the bike industry, stopped answering the phone. At the end, we sold these for $89.99 |

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... |
