Paul's Engineering Moon Units Cable Carrier
These were the first high quality replacement cable carriers to come to market. At the time they were a novelty because everyone had been to the steel and stamped aluminum factory mass produced type, and people thought it was machining overkill. This year, 1994/95 everyone sees this as a quick easy small trinket to make a profit from, and Paul Price was first. The Moon Unit is machined from plate aluminum in an arched shape. The piece is milled to make 3 thicknesses. The top of the arch where the brake inner wire passes through is 7.33mm thick. The center area where an oval of material is milled away is 1.88mm thick. At the bottom, there is two troughs that the straddle cable lays in and hangs from. These troughs are 5.48mm thick with a cut is made across the top that is 2.35mm wide. The middle area between these two troughs is milled away to allow extra length of inner wire to pass through. The Moon Units use a cable end clamp to cinch the carrier from the inner wire. The end clamp is machined from 8mm hex rod stock that is drilled with a 2.48mm hole through the rod. The piece is turned to make the hex stock round for 8mm of the 13.5mm length. The interior of the piece is drilled and tapped with 5mm by .8mm threads. The brake inner wire passes through the top of the arched aluminum carrier, into and through the now hollow rod piece. A steel 5mm x .8mm x 10mm bolt tightens against the cable, clamping it to the outer aluminum barrel. The steel bolt weighs 3 grams and can be replaced with a Ti version of the same by using a Ti water bottle cage bolt, they are the same. Moon Units are sold in pairs, anodized in Blue, Black, Lavender, or Silver. The needed 4mm hex wrench to tighten the bolt isn't included. Each of the 2 Moon Units weighs 6.5 grams. Made in USA.

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... |
