Glass Cutting Saws

Glass Cutting Saws

There are many tools that you will need to finish projects around your house, and one of the most important tools that you will is a glass saw. Glass cutting saws are the perfect tool to help you as you place in a new window, create your own glass patterns, repair your bathroom, and many other tasks that require glass to be cut.
Rather than opting for the more expensive option of purchasing glass grinder bits, glass saws can be a cheaper investment that actually works more effectively. Glass saws make cutting glass easy, and you can easily cut pieces of glass with straight edges. You may find that cutting large pieces of glass is far easier with glass cutting saws than will glass grinder bits, and each tool has their own particular use.

When replacing a window or putting in a new one, it is vital that you have a pane of glass that has straight and even edges. Using a glass grinder bit will simply take too long and is far too inaccurate. Glass cutting saws are designed to quickly and effectively cut through panes of glass, and you can be sure that your glass will be cut correctly when using glass saws.

Often glass cutters work well for thin panes of glass, but they are unable to handle the larger, thicker panes of reinforced or fused glass. When handling thicker or stronger panes of glass, glass cutting saws are the best thing to use, as they are designed to cut through thick panes of glass as easily as a tile cutter can cut through porcelain.
There are three kinds of glass saws commercially available today:

 Wire saws use diamond blades that can cut in any given direction, similar to the way a jigsaw is able to handle twists and turns when cutting wood. This kind of glass saw tends to heat the glass fairly quickly, so it is vital to keep your glass wet.

 Ring saws use a circular blade that is coated with diamonds to chop through the glass. They are able to cut in most directions, and they are more versatile than the average band saws. A drawback to using ring saws is that the blade used to cut through the glass is thicker than the band saw, meaning that more of the glass is lost when using ring saws.

 Band saws cut through glass with a diamond tipped blade, and they are the most common type of glass saw available. The blade simply cuts through the glass when it is pressed firmly onto it, though it remains flexible and bendable enough to etch intricate and detailed patterns into the glass.

It is vital that you keep wetting the glass you are cutting when using glass cutting saws. Glass saws heat up the glass with all of its friction, and you could end up with a chipped and cracked pane of glass if you don't keep adding water to the pane of glass to keep it from heating up too much.

What to Look for in a Quality Cordless Drill

What to Look for in a Quality Cordless Drill

A cordless drill is likely to be one of the most used and relied on tools by the enthusiastic do-it-yourselfer and comes in different sizes and configurations. Due to the portable nature, these tools are perfect for using on offsite locations and give a high level of power via the lithium-ion rechargeable batteries. Whether you are looking for a regular, hammer, or impact drill, you will still find that these tools relying on the rechargeable batteries as a power source are able to give enough power and performance to take on even the most difficult projects.
Here are some of the points to consider when it comes to deciding on the best quality cordless drill:

Voltage: One of the key factors to searching the right cordless drill relates to the voltage level, which is often in the region of 14.4 to 18-volts. A high voltage rating is able to offer longer performance and power. Power tools relying on the lower rated batteries will be perfect for the at-home use, while the higher voltage options, such as those at 36-volt or more, are ideal for the construction site.

A great feature of the rechargeable drill batteries is that they can be used in multiple tools, so if you are likely to be using the same battery for several tools, such as a cordless drill and circular saw, you might wish to invest in the higher rated units to make sure the option for longer usability is available.
Fast charging: Since you want to limit the downtime with the power tools, a fast charger is likely to be highly desirable in most situations. Some of the latest drills are starting to feature very fast charging units, which have the potential to fully charge the lithium-ion batteries within a period of 15 to 25 minutes. Many of these cordless drills features an auto cut out switch which makes certain the power tool battery isn't overcharged which would result in long-term damage to the battery pack.

High torque: A further feature to expect for high power and efficiency relates to the torque power. A high torque rating is highly desirable to give that extra performance level and comes on the drills with the higher voltage level. If you have the cordless drill with the high torque rating you want a pressure-sensitive trigger featured since this will benefit by decreasing the speed of the drill when a screw head starts to reach full depth.

How To Find The Power Drill That Best Suits You

How To Find The Power Drill That Best Suits You

Using the right power drill can make a significant improvement in your working results and in your workday itself. Just like wearing a comfortable pair of shoes, the drill you use should be a good fit. Simply remember these few steps to help you find the drill that most compliments you and your needs.
First, its important to determine the types of projects you plan to use the drill for. Degree of use is a huge factor in both the type of drill that you want, and the way it will perform under certain conditions. Chances are, if you rarely break out the drill, and use it for primarly small, simple tasks, you won't need too much more than a very standard drill. Of course you may want more, but, in most cases, drilling a few screws about the house doesn't require an industrial grade power drill. On another hand, if you frequently and heavily use your drill, you'll certainly want a more powerful tool with a bit more spunk in the features department - one that will stick with you for the long haul. In the tool business, quality and price almost unfailingly go hand-in-hand, so I feel safe saying that the more you spend, the better the drill.

Determine between corded and cordless. Corded drills are often more powerful, lightweight, and don't rely on (sometimes unreliable) battery power. They are, however, tethered to a wall which means less mobility and more hassling with power cords - this is especially inconvenient during overhead drilling. Cordless drills, on the other hand, are free-wheeling and always convenient, but they do rely on battery power and a good charge. Despite occaisionally being a bother, if you can keep up with you charging cysles, this is not usually an issue. If you do choose a corded tool, look for one with a longer cord. The more space you have, and the less often you need to use an extension cord, the better.

If you choose a cordless tool, you'll need to decide between NiCad, NiMH, and Li-Ion batteries. Li-Ion, or Lithium Ion batteries, are by far the most popular battery choice, and for good reason. They are extremely lightweight, powerful, long-lasting, fast-charging, and simply boast an unmatched high-performance. All this goodness comes at a price though rendering NiMH or NiCad a more affordable option. Despite price, however, many craftsman would rather pay a bit more for their first lithium ion battery, than buy a replacement for their NiCad or NiMH drills. Still, NiMH and NiCad batteries are perfectly suitable for most applications.

Voltage. Determine how much power you want from your drill. Mild to moderate users should do just fine with a 12 - 14 volt power drill, while moderate to heavy users should definitely opt for 14 - 18 volts. Of course your applications also play a role in the voltage you'll require from a drill. If you use the tool every day but only for tightening the loose electrical outlet behind the back-door - you don't necessarily need to invest in an 18 volt drill. Similarly, if you only use your drill once per year, but every time you use it you build a deck or a tree-house, you'll want those 18 volts and a bigger, high-power/performance tool.

Knowing the features and inclusions you need and expect from your drill is a vital piece of the choosing process. For many people, a bare-bones screw gun is more than enough. Others require all the perks a tool can offer like reversing, variable speeds, a keyless chuck, or LED light (all of which are really good to have). Most industrial workers and frequent users prefer a drill that can make each job a bit easier, and for the most part, the more features you have on the drill, the more pleasant your working experience. Additionally, batteries, a tool bag, charger, and sometimes a bit extra are included in most drill kits. You may not need these things, but if you do, look for kits. Although they are initially more expensive than the tool alone, you'll save money and stress in the long run.

Research brands to find which one meets the most of your needs. Here, there are a few things to consider; many craftsmen are already loyal to a specific brand, this shouldn't stop you from cross checking other manufacturers to ensure your getting the most for your money. Additionally, not all tools or manufacturers are created equally; similar to most craftsman, many manufacturers have a particular forte, or a tool they build best - I tend to like Makita and Milwaukee for drills. Do a bit of searching and you'll find a tool and manufacturer you like. This is important particularly if you buy cordless. Often you can use batteries interchangeably between tools of the same manufacturer. This helps you save money and certainly time if you have more than one battery.

After entertaining this bit of research, you should lay down a budget. It is far to easy to both under and over-spend when buying a drill. If you have a budget prepared before-hand you're much more likely to keep your cool among super-sales and even a super-dazzling, but too expensive drill. Keep in mind that, in the world of power tools, you always get what you pay for; a cheap drill can fast turn into a bad, regretable investment. Likewise, a drill on the more expensive side might be too much for both your budget and your basic needs.

Finding a good warranty is another piece of this puzzle. Investing in a drill that includes a good warranty indicates its manufacturer has faith in their tools and their ability to do their jobs right; this kind of guarantee is always comfortable to work with. Most of the high-end manufacturers include a one year warranty on chargers, batteries and corded tools, and around three years on their cordless equipment. Its also worth noting here that Hitachi includes a ten year warranty on most of their cordless lithium-ion line.

Lastly, before you take the plunge, if you can, it's good to hold the drill to ensure the tool is comfortable and functional in your hands. Personally meeting your tools before purchase is not always possible or necessary but is notheless worth considering.

Simply considering these few steps can be the difference between an unfufilling project and results that will impress for a life-time. Entertaining this simple bit of research will help you enjoy the right drill for years to come.

Brain Surgery (Craniotomy) - Questions & Answers

Brain Surgery (Craniotomy) - Questions & Answers

Craniotomy is a cut that opens the cranium. During this surgical procedure, a section of the skull, called a bone flap, is removed to access the brain underneath. The bone flap is usually replaced after the procedure with tiny plates and screws.

A craniotomy may be small or large depending on the problem. It may be performed during surgery for various neurological diseases, injuries, or conditions such as brain tumors, hematomas (blood clots), aneurysms or AVMs, and skull fractures. Other reasons for a craniotomy may include foreign objects (bullets), swelling of the brain, or infection. Depending on the reason for the craniotomy, this surgery requires a hospital stay that ranges from a few days to a few weeks.


What is a craniotomy?

Craniotomy is any bony opening that is cut into the skull. A section of skull, called a blone flap, is removed to access the brain underneath. There are many types of craniotomies, which are named according to the area of skull to be removed . Typically the bone flap is replaced. If the bone flap is not replaced, the procedure is called a craniectomy.

Craniotomies are also named according to their size and complexity. Small dime-sized craniotomies are called burr holes or keyhole craniotomies. Sometimes stereotactic frames, image-guided computer systems, or endoscopes are used to precisely direct instruments through these small holes.

Burr holes or keyhole craniotomies are used for minimally invasive procedures to : -

* insert a shunt into the ntricles to drain cerebrospinal fluid (hydrocephalus)
* insert a deep brain stimulator to treat Parkinson Disease
* insert an intracranial pressure (ICP) monitor
* remove a small sample of abnormal tissue (needle biopsy)
* drain a blood clot (stereotactic hematoma aspiration)
* insert an endoscope to remove small tumors and clip aneurysms......

Skull base craniotomies can be used to : -

* remove or treat large brain tumors, aneurysms, or AVMs
* treat the brain following a skull fracture or injury (e.g., gunshot wound)
* remove tumors that invade the bony skull



Who performs the procedure?

A craniotomy is performed by a neurosurgeon; some have additional training in skull base surgery. A neurosurgeon may work with a team of head-and-neck, otologic, oculoplastic and reconstructive surgeons. Ask your neurosurgeon about their training, especially if your case is complex.



What happens before surgery?

You will typically undergo tests (e.g., blood test, electrocardiogram, chest X-ray) several days before surgery. In the doctors office you will sign consent forms and complete paperwork to inform the surgeon about your medical history (i.e., allergies, medicines, anesthesia reactions, previous surgeries). You may wish to donate blood several weeks before surgery. Discontinue all non-steroidal anti-inflammatory medicines (Naproxin, Advil, etc.) and blood thinners (coumadin, aspirin, etc.) 1 week before surgery. Additionally, stop smoking, chewing tobacco, and drinking alcohol 1 week before and 2 weeks after surgery because these activities can cause bleeding problems.


What happens during surgery?

There are 6 main steps during a craniotomy. Depending on the underlying problem being treated and complexity, the procedure can take 3 to 5 hours or longer.

Step 1 : - Prepare The Patient No food or drink is permitted past midnight the night before surgery. Patients are admitted to the hospital the morning of the craniotomy. With an intravenous (IV) line placed in your arm, general anesthesia is administered while you lie on the operating table. Once asleep, your head is placed in a 3-pin skull fixation device, which attaches to the table and holds your head in position during the procedure. Insertion of a lumbar drain in your lower back helps remove cerebrospinal fluid (CSF), thus allowing the brain to relax during surgery. A brain-relaxing drug called mannitol may be given.
Step 2 : - Make A Skin Incision After the scalp is prepped with an antiseptic, a skin incision is made, usually behind the hairline. The surgeon attempts to ensure a good cosmetic result after surgery. Sometimes a hair sparing technique can be used that requires shaving only a 1/4-inch wide area along the proposed incision. Sometimes the entire incision area may be shaved.

Step 3 : - Perform A Craniotomy, Open The Skull The skin and muscles are lifted off the bone and folded back. Next, one or more small burr holes are made in the skull with a drill. Inserting a special saw through the burr holes, the surgeon uses this craniotome to cut the outline of a bone flap. The cut bone flap is lifted and removed to expose the protective covering of the brain called the dura. The bone flap is safely stored until it is replaced at the end of the procedure.

Step 4 : - Exposure The Brain After opening the dura with surgical scissors, the surgeon folds it back to expose the brain . Retractors placed on the brain gently open a corridor to the area needing repair or removal. Neurosurgeons use special magnification glasses, called loupes, or an operating microscope to see the delicate nerves and vessels.

Step 5 : - Correct The Problem Because the brain is tightly enclosed inside the bony skull, tissues cannot be easily moved aside to access and repair problems. Neurosurgeons use a variety of very small tools and instruments to work deep inside the brain. These include long-handled scissors, dissectors and drills, lasers, ultrasonic aspirators (uses a fine jet of water to break up tumors and suction up the pieces), and computer image-guidance systems. In some cases, evoked potential monitoring is used to stimulate specific cranial nerves while the response is monitored in the brain. This is done to preserve function of the nerve and make sure it is not further damaged during surgery.

Step 6 : - Close The Craniotomy With the problem removed or repaired, the retractors holding the brain are removed and the dura is closed with sutures. The bone flap is replaced back in its original position and secured to the skull with titanium plates and screws . The plates and screws remain permanently to support the area; these can sometimes be felt under your skin. In some cases, a drain may be placed under the skin for a couple of days to remove blood or fluid from the surgical area. The muscles and skin are sutured back together. A turban-like or soft adhesive dressing is placed over the incision.



What happens after surgery?

After surgery, you are taken to the recovery room where vital signs are monitored as you awake from anesthesia. The breathing tube (ventilator) usually remains in place until you fully recover from the anesthesia. Next, you are transferred to the neuroscience intensive care unit (NSICU) for close observation and monitoring. You are frequently asked to move your arms, fingers, toes, and legs...

Reciprocating Saw Reviews - Uses, Blades and Cordless

Reciprocating Saw Reviews - Uses, Blades and Cordless

Some time ago, picking a cordless tool over its cord attached comparable version most likely meant giving up a considerable amount of electrical power. Furthermore, the batteries on cordless tools did not really last very long, making individuals to charge your saw frequently, an inconvenient necessity when it comes to those doing lengthier tasks. Luckily, this has changed in recent years. The cordless tools are now more powerful and they last longer than they have in the past. On top of that, they're significantly more mobile than ever. More good news is the fact that this particular rise in quality has been accompanied by a lowering in price range.
In our reciprocating saw reviews, we recognize that the benefits of a good quality cordless saw are evident. Probably, even more benefits with cordless reciprocating saws compared to its counterparts. It will be easier for an individual to access hard to reach places such as pruning tree limbs or points where you have to cut through PVC piping or install wirings inside your wall structure. On the contrary, the corded types only extend to the length of the actual cord, in some cases restricting access to only 50 feet. Additionally, cordless saws are safe to use if you're sawing in a damp area.

Basically, there's genuinely no reason (with the exception of personal preference) to buy a cord attached reciprocating saw rather than the cordless version considering the improvements in battery power. Nevertheless, cordless reciprocating saws are definitely not made the same, so you need to be careful in your options and select the appropriate saw for your specific situation.

Reciprocating Saw Reviews - Characteristics of Reciprocating Saw Blades

Identifying all the strengths and weaknesses of each saw was a crucial step in our reciprocating saw reviews process. One of the best characteristics of a reciprocating saw is its enormous versatility, because of the large variety of saw blades it can easily be fitted with.

Do you need an instrument that cuts through metal, piping, timber, drywall as well as fiberglass?  With the correct blade, the reciprocating saw can do all of these jobs and more.

There are a variety of blades to pick from (an important step in the reciprocating saw reviews process), the type of blade you choose will be determined by the depth and consistency in the material that an individual wants to cut.

Reciprocating Saw Reviews - (Blades) Dimensions

Reciprocating saw blades can range in length from 2.5 to 12 inches. Know in advance how in depth you would like the cut to be, in order to choose the right length. In regards to width, having a more significant width will certainly decrease wobbling and also bending. The thickness one wants equally depends on what you're want to achieve: most tasks need a thickness approximately .035 inches, although .05 inches is better for the truly challenging jobs.
Blades may possess as few as three or up to 24 teeth per inch (TPI). A blade's TPI is one of its most significant characteristics, and greatly affects the way the saw is going to cut.

A lower TPI means faster, rougher cuts; larger TPIs are suited for slower, smooth cuts. Which one you want depends mostly on the material you'll be utilizing the blade on. When cutting metal, for example, you'll definitely require a blade that has a high TPI. There are also "variable-pitch" blades which possess more teeth in one section of the edge than another.

Material

Most blades are made out of one of four types of content:

* Carbon steel: flexible, affordable, but wears easily

* High-speed steel: more durable but less flexible than carbon steel.

* Bi-metal: combines the advantages of carbon and high-speed steel and can last substantially longer than both.

* Carbide grit: best used for materials which include fiberglass, ceramic tile, and also concrete board.

You will find that some blades are less expensive than others; this is due to the fact they are less rugged, so think about what you need to have before you buy.

(Reciprocating saw reviews tip) Once you discover that you'll be using the same reciprocating saw blade multiple times per day, a money-saving idea is to buy one which can withstand heat for a extensive time periods (ie. High-Speed Steel); however, if not, then you can certainly go for an inexpensive solution and make sure that you have back up blades.

Common Types of Blades (Reciprocating Saw Reviews)

Four common reciprocating saw blades include:

* Course-tooth: designed to cut green wood.

*Fine tooth: designed for smooth cuts in plastic, hardboard and wood

* Hack saw: used to cut metal that's up to 1/8 inch dense

* Knife: versatile design good for cutting products such as cloth, leather, linoleum, and rubber.

Moreover, there are usually numerous kinds of specialized blades which are designed for tasks that are more unique.

Other Points to take into consideration (Reciprocating Saw Reviews)
Some of the cutting blades require nominal upkeep. The reciprocating saw blades that are created for cutting large materials need to be lubricated with oil frequently. One thing to keep in mind is the fact that many of the reciprocating saws are much simpler when it comes to blade changes.  Specifically those saws designed with a keyless blade clamp, which enables you to replace the blade with less time and effort than the other types of saw. Consequently, this feature is one thing that needs to be seriously considered should you expect frequent blade changes. Reciprocating saw blades are the most important components of the saw, considering that the blades are what make the Recipro-Saw so adaptable and convenient.
