Air Tool Consumption Guide Specialised Welding Products Ltd AIR TOOL CONSUMPTION GUIDE When assessing the size of a compressor to operate air tools and equipment please use the air compressor FAD (free air delivered) - this is the correct volume you need to know in order to ensure that a compressor wilf operate your equipment efficently. Column 1 is manufacturers stated tool consumption under continuous use in CFM. Column 2 is average time of use in seconds. Column 3 gives CFM required to operate tool under normal conditions of use.

    Rafael A. Barrantes QAS 515 Human Factors Pneumatic Rivet Gun Exchange Program on the C-17 Program November 29, 2005 History Charles Brady King of Detroit invented the pneumatic hammer in 1890. In the late 1800’s and early 1900’s the rivet guns where were used in the rail road industry. The guns were used on small rivets on locomotives as well as swaging and sealing boiler tubes. The guns were also used for breaking old welds in thin steel. The first successful all metal airplane was built in 1915 in Germany by Junkers. The first American metal airplane to be produced in large numbers was the Ford Tri-Motor. The planes were built from 1926 thru 1933. With the advent of the metal plane, rivets were used as the primary fastener to bond skins to primary structure. Process Description Riveting is a two person task. One person is typically inside the aircraft and the other outside. The workers switch between riveting and holding a bucking bar behind the rivet. Workers communicate verbally with or without radio head sets. Workers drive approximately 400-600 rivets per day. The holes to be riveted are drilled out then reamed out to final hole size with a hand drill. The rivets are then placed in the open hole. The bucking bar is positioned behind the rivet by one worker and the rivet gun is held at the head of the rivet by the other worker. The rivet gun operator then squeezes the trigger in several short bursts to drive the rivet into place.

  • Construction Manual, Which, Together with a Complete Set of Drawings Will Help You to Accomplish This Wonderful Feat: to Build and Fly Your Own Two-Seat Aircraft
    FOREWORD Dear Builder: Congratulations on your decision to build a Zenith aircraft. Here is the construction manual, which, together with a complete set of drawings will help you to accomplish this wonderful feat: to build and fly your own two-seat aircraft. The first part of the manual deals with some of the tools required for this project and the procedure with which to use them efficiently. Materials and hardware are also presented as well as tips on workmanship, corrosion protection and tolerances. The second part is a progressive step-by-step construction guide; beginning with the rudder assembly, it describes every aspect of airframe construction. The last part of this manual is a “weight and balance form”. The drawings and manual have been laid out to allow the average builder to understand them without having to write or call the designer or factory. They are not "perfect" or in color but supply all the information required completing your aircraft to the design specifications. It is important to remember that builders have used the proposed building sequence successfully for over two decades. It would therefore be wise to use this experience and stick to the sequence. The secret of good progress is not to work like crazy in sudden short-lived spurts; it lies in steady and continuous effort. Homebuilding your aircraft is a tremendously rewarding hobby. You are the one with enough courage to do what others only dream of. Homebuilding is a useful, educational and recreational activity. While learning, you will enjoy building, and then flying... and you are contributing to the progress of aviation.

  • Buck Riveting Basics Tools and Techniques
    Buck Riveting Basics Tools and Techniques Written by Steve Bryant (2014) Revised by Steve Hingtgen (2021) Overview Solid rivets, also referred to as buck rivets, have been used as the primary fastener type in the construction of aluminum-framed travel trailers for more than 80 years. These trailers (and a few motorhomes) employ a number of construction techniques (including bucked rivets) that have been borrowed from the aircraft industry. Bowlus, Airstream, Curtis Wright, Avion, Silver Streak, Spartan and many other manufacturers have used bucked rivets. These solid rivets are lightweight, strong and inexpensive fasteners. That’s why they were chosen for aluminum aircraft construction and the same advantages hold true for travel trailers. It’s important to note that in order to repair a travel trailer that uses bucked rivets, the interior walls in the vicinity of the bucked rivets under alteration must be removed in order to access the back side of the rivet so that a bucking bar can be used. Another category of rivets, blind rivets (commonly referred to as pop rivets), may be used to repair riveted panels from one side only. The well-known shaveable bulb-tite “Olympic” rivet is in this category. Although, blind rivets have the advantage of convenience, they also have a number of limitations; generally the repair or alteration will not have the same appearance, strength or waterproof characteristics as the original bucked rivet approach. Basic Principles A bucked rivet is a round fastener that attaches two or more pieces of metal together. The rivet is driven by a rivet gun (a specialized pneumatic hammer) with an attached rivet set (strike surface) shaped to match the rounded shape of the manufactured head of the rivet.
