Pechauer Cues Parts and Components


It only makes sense that those pool players looking for their own personal or custom cue sticks would, more often than not, be concerned with the details of its construction and crafting. After all, a personal cue stick is no small investment, and for someone who spends many hours playing a game they love, quality of the equipment is important. When an item like a pool cue is hand made with superior care and craftsmanship, you can feel relatively sure that it will play well too.

Pechauer Cues Parts and Components

For those who take this sort of an interest, Pechaer cues are worth taking a close look at. Probably the most outstanding characteristic of Pechauer cues is that the company hand crafts virtually all of the parts of the cue, many of which other cue makers buy from outside sources. Joint screws, ferrules, brass inserts, and weight screws are all manufactured in-house. Pechauer even has its own forest and mill, which allows them to hand select hard rock maple with only the straightest grain and best characteristics for their shafts.

The butt sections of Pechauer cues are quite striking, handcrafted from such materials as cocobolo, tulip wood, ebony and other materials. The custom fit inlays show no glue lines. A color coded weight screw system allows easy changing of weight. Beautiful and comfortable wraps round out these hand crafted beauties. Pechauer cues are made with stainless steel joints, providing for a stiffer hit, so be sure this is your preference or try them out before buying.

Pechauer offers a complete line of cue sticks ranging in price from $280 for the basic Pro-J to over $1500 for some of the most beautiful cues around, so you can make a choice that fits virtually any budget. But you can be sure that each cue is made with the same care and craftsmanship.

two main types of pipe fittings


There are two main types of pipe fittings commonly used in heating, ventilation and air conditioning systems; flanged and screwed. Screwed pipe fittings use a male and female thread combination and when screwed together tighten to form the joint. A flanged pipe fitting has a lip or extension projecting at a right angle to its surface. This lip is bolted to the facing lip of the adjacent fitting for added strength. Because of the strength of this fitting, flanged fittings are recommended for 4-inch pipe or larger.



Both of these pipe fittings are used to meke temporary joints because you can ultimately take them apart when needed. If the joint is ever brazed, soldered or welded the join is considered permanent as the join will not come apart. The advantage of these two temporary joints is that it can be easily disassembled for repairs down the road.

The typical pipe fittings can be divided on the basis of the following six functions:

Reducing or enlarging
Branching
Extension or joining
Shutoff or closing
Union or makeup
Direction
Reducing or Enlarging Fittings: Both bushing and reducers are examples of reducing or enlarging fittings. Thier function in pipe installations is to connect pipes of different sizes. The difference between a bushing and a reducer is distinguished by their construction. A reducer is a coupling device with female threads at both ends. A bushing has both male and female threads on each end.

Branching Fittings: A branching fitting is used to join a branch pipe to the main line. These fittings are used for Tees, Crosses, Elbows with side outlets, Y branches and Return bends.

Extension of Joining Fittings: Nipples, locknuts, couplings, offsets, joinst and unions are all examples of extension or joining fittings. With the possible exception of an offset, these fittings are designed to joiun and extend a length of a pipe.
