“I pay your SALARY”

a Private college STUDENT once said “I pay your SALARY” to his teacher… the statement should never end there boy, you should add the following statement… “To teach and EDUCATE me, not to praise me”

I pay for my studies. so what?

12pm 1st Aug. 2012

“I pay for my studies. so what? ” DOES NOT GIVE YOU THE RIGHT, SIMPLY NOT TO USE YOUR COMMON SENSE! OTHERS ARE USING THE SAME FACILITIES TOO… REMEMBER THIS! FOR EVERY FACILITY YOU F**UP BECAUSE OF YOUR IGNORANCE, YOU ARE “literally” F**KING UP with EACH and EVERY STUDENT THAT “PAID THEIR STUDY FEE TOO!” which IS YOUR OWN GOOD FRIENDS! so TELL ME WHAT?

New York Balance

The New York Balance is a very simple instrument for demonstrating a basic principle of physics. Actually several principles can be studied such as torque, levers, center of gravity, and kinetic energy.

The unit consists of a center stand with a cast iron base, a 50 centimeter ruler, three knife edge clamps, a 50 gram weight and a 100 gram weight. Make sure to tighten the mounting screw securely for the stand and cast iron base. One of the knife edge clamps should have the hanger wire removed. This clamp will act as your fulcrum, or fixed point, from which the 50 centimeter ruler will pivot.

Laboratory Activities:
Balance and Levers
Rotational Equilibrium with a New York Balance
Lever: Equilibrium and Torque

KYDEX

KYDEX® thermoplastic sheet Is manufactured from an acrylic / PVC alloy that has some very unique characteristics. Tough, nonporous, noncorrosive, chemical resistant, fire retardant and thermo formable. KYDEX® sheet has very good abrasion resistance and virtually no moisture absorption. Material is normally 48" x 96". Thickness runs from .028" to .500" thick. Roll stock is available in the thinner grades. Several different surface patterns are available.

General Information About KYDEX® Sheet

The KYDEX® name is a trademark of the Kleerdex Company for their proprietary thermoplastic. Each grade is custom suited for your particular application or performance need. KYDEX® Sheet Is manufactured by Kleerdex Company under an ISO 9002 certified quality system and has been satisfying customer needs for over 30 years. KYDEX® Sheet is high quality and specialty in nature. They typically should be considered for applications requiring any or all of the following benefits:
1.Fire Retardancy
2. High Impact Resistance
3. Rigidity
4. Superior Chemical Resistance

Thermo formability KYDEX® Sheet is typically not a cost-effective substitute for cheaper thermoplastics such as polyethylene, styrene, or cheap ABS, unless those materials are not performing satisfactorily. KYDEX® Sheet can be very competitive and effective as an alternative to painted metal, fire-retardant ABS, Noryl®, Lexan® (polycarbonate), etc. KYDEX® Sheet complies with Underwriter’s Laboratory, CSA, Building Code and / or FAA flammability requirements. Because of the high impact resistance of KYDEX® Sheet, it has a longer in service life and is very durable. The rigidity allows for a better feel and /or the ability to down gauge.

Its superior chemical resistance allows it to be used in harsh, chemically rich environments. It also makes KYDEX® Sheet extremely cleanable because harsh cleaners do not damage the texture or the color of the material. KYDEX® Sheet has excellent forming properties that result in uniform wall thicknesses and crisp detail. There are a complete range of grades, colors, sheet sizes and textures available to meet the most demanding applications.

To choose the grade of the KYDEX®Sheet that will work best for you, ask yourself a few questions:
1. What are you making?
2. What product are you using now?
3. What specifications or regulatory compliance must you meet?
4. What are your physical and visual performance requirements in sense of how is the product being used?
5. What is your economic situation?

Please take time to read the Kydex Material Data Sheets; there are hazards involved in the process of using Kydex. Stay safe, have fun, and good luck...

The links below will take you to the Kydex LLC website:
1. Product Data Sheets
2. Kydex MSDS

The site below has some very useful information’s for those that are just starting. Some people that have been doing it for a while can also benefit from reading the technical briefs. It contains information such as, cleaning solvents that should be use or those that can damage Kydex, glue that works effectively with Kydex, how to paint, how to engrave, and basics such as temperature ranges or heaters to use. It will even have techniques depending on the process used to mold it. Be aware that there are different types of Kydex. All of them have suitability for certain applications.

Adams Arms Gas Piston System.

The Adams Arms Gas Piston System is an end user installed after-market product for Mil-Spec ARs. It will fit on any AR barrel with a .750" or 3/4" diameter at the shoulder where the front sight base sits. The Pistol version will work on barrel lengths from 7.5" to 8.5". The Carbine version will work on barrel lengths from 10.5" to 16" that has an existing carbine gas system. The Midlength version will work on barrel lengths from 16" to 18" that has an existing midlength gas system. The Rifle version will work on barrel lengths from 18" to 24" that has an existing rifle gas system.

This is the list of handguards Adams Arms currently know will work with their system without any modifications, this list will be updated as more handguards are discovered to work with their system:
