Choose The Right Hinge For Your Project

Because the display of hinges in a home improvement and hardware stores can be dizzying to the inexperienced homeowner, many need some help to know which hinge is correct for the woodworking project or home repair. The first essential step would be to narrow the selection based on weight, shape and size, so that the hinge will be appropriate for the materials used in the project. Large heavy hinges are fine for doors, but not appropriate for smaller, delicate wooden boxes and so on.

In addition, some hinges are designed as reversible hinges, so that either end can be mounted to the top. Other hinges are more decorative and must be installed in a certain position. There are also hinges for left-hand and right-hand doors to consider as well. The loose-pin hinge used for hanging doors is made so that the hinge pin is inserted and removed from the top. Right-hand hinges and left-hand hinges can be distinguished by simply standing on the outer side of the door to see if the door opens to the right side or to the left side.

One detail that some do-it-yourself homeowners don't consider is how much of the hinge will be visible when the project is complete. If the hinge shows, it may be best to choose something more decorative, though some homeowners prefer simple and functional hinges to show as well. This depends on personal taste. Some people prefer the hinge to be hidden, so thought should be given to how the hinge will function in this case.

Shopping for the appropriate hinges can be much easier if the homeowner can ask good questions and understands the printed information about each type. This list may help.

? Back flap hinge ? a version of the butt hinge, commonly used for furniture

? Ball-bearing hinge ? permanently lubricated but slightly more expensive, for heavy-duty doors

? Butt hinge ? normally range in size from 13 mm to 150 mm. Varieties include rigid pin and loose pin. Often used for mounting home doors and cabinet doors

? Butterfly hinge ? for lightweight doors, in a variety of shapes and patterns

? Double-acting hinge ? opens in either direction, usually on folding doors

? Flush hinge ? less strength than butt hinge, often used for cabinets, concealed except for hinge barrel

? Knuckle hinges ? loose joint hinge, decorative, shows only the knuckle

? Offset blind hinge ? full opening and swing away, screen/storm doors

? Parliament hinges ? when hinge pin must extend past door face

? Pivot hinge ? versatile, recessed doors, overlay doors, flush doors

? Spring-loaded hinge ? automatically closes door, adjustable tension available

? Table top hinges ? leaf section tables

? Concealed hinges ? 25 mm to 36 mm in size, adjustable after fitting, chipboard and MDF

In addition to these hinges, there are a number of specialty hinges, including the strap hinge, T-hinge and continuous hinges. Some are designed for heavy-duty use while the continuous hinge is perfect for chest lids, cabinets and so on. A piano hinge is a continuous hinge.

A CompactPCI (cPCI) system is a 3U or 6U ("U" is a unit of measurement of the height of a rack-mounted device, with one rack unit, or RU, equaling 1.75") Eurocard-based industrial computer which has all of its boards joined by way of a passive PCI (Peripheral Component Interconnect) backplane. The pin assignments of the connectors are documented in standards, published by the organization PICMG U.S. and PICMG Europe (PICMG means "PCI Industrial Computers Manufacturers Group").

The connectors and the electrical rules enable eight boards in a PCI segment. Multiple segments are allowed with bridges. (A Eurocard is a European standard format for PCBs--insulated boards on which interconnected circuits and components such as microchips are mounted or etched--which can be plugged together into a standardized sub-rack.)

Yes, that's a mouthful. More simply put, cPCI systems were originally created to be industrial buses with an extremely high bandwidth for multiple computerized applications including telecommunications, computer-to-computer communications, real-time machine control and data acquisition, industrial automation, instrumentation, and military systems. The CompactPCI system facilitates high speed computing, modular and robust packaging design, and long term manufacturer's support.

Norbert Hauser, Vice President Marketing at Kontron, says of the Kontron ITC-320 series of cPCI systems, "[This system] is an ideal product for upgrading existing compact-sized embedded computers to a state-of-the-art processing unit with PCI-Express connectivity on the backplane." CompactPCI is positively the wave of the future as well as the present for industrial applications, and it's a system that's rapidly being expanded. According to a recent press release from the European PICMG, that group has "formed a technical subcommittee to extend the current CompactPCI standard for both the 3U and 6U form factors, mainly for applications in industry, avionics, transportation, medical and in telecommunications systems that use cPCI"

The current CompactPCI standard lacks support for inter-operation with serial busses such as PCI Express, Ethernet, SATA/ SAS and USB at the backplane. CompactPCI Express with support for PCI Express has no rear I/O and there is no cost-effective migration path from CompactPCI without bridge slots. Its proposers intend that this extension will not require switched fabrics, and there is not intention to define them.

The basic idea is to define a new peripheral slot supporting PCI Express as well as SATA/SAS, USB and Ethernet. Such slots can be used for PCI Express expansions (for example), but also for hard disc RAID arrays, Ethernet switches, or USB-based WiFi solutions; all modern busses would be supported on each peripheral board. A star architecture will be used to connect the system slot to the peripheral slots.

There are few ways to get the adrenaline rush and also get the benefit of experiencing nature than going on an off road trip. Doing so is incredibly complicated if the one embarking isn't sure what they need- both for the vehicle and for themselves should they become hurt in some shape or form.

Knowing what vehicle to pick means all the difference in the experience going to be had. Obviously a car or smaller truck isn't going to do very well, since they sit lower to the ground and may get damaged easily. Larger trucks or SUVs are more accustomed to the wear and tear, and will also be able to withstand other forces of nature such as traction control.

The tires that come with most vehicles, even for off road specialty vehicles, are often inadequate. This depends on the conditions in which the driver is going to be undergoing the adventure. If there is a muddy or rocky terrain, special tires that can grip with special textures and techniques will need to be used to prevent getting stuck.

Just like the tires, most factory vehicles will not have the best suspension in the world. The suspension is vital for a smooth ride- even while climbing rocks and scaling cliffs. A subpar suspension will quickly give out and often times "bottom out" the vehicle- which can cause damage in the hundreds or thousands of dollars depending on the accident. As such, obtaining a better suspension is usually necessary.

Off road adventures are also a competitive sport- although it comes in many forms. The most popular is Formula Off Road racing, in which some of the most extreme off road adventures can be had. Vehicles in this competition will need to be highly modified to take all types of abuse- even descending or ascending near vertical cliffs. This sport is very dangerous, and it should be noted that there are strict safety regulations and training instructions to gain entry into this competition.

The off road lifestyle doesnt have to be as extreme as most make it out to be. In many cases just a casual stroll through the forest in an all terrain truck or SUV is enough adrenaline to qualify the act for off road classification. Since there are so many types of off road techniques, it's recommended to talk to a professional who can recommend the best one.

Final Thoughts

Defying the fact that most people would rather stay in and watch television in their evenings is a great way to show that society isn't afraid to go outside, get a little muddy, and in the end have some fun. For more information, consult books and help sources on the subject of off road adventures.
