Another method of assuring a clean hole is to first drill a small pilot hole all the way through, then drill half way with the dimensional bit, turn the piece over, and finish from the other side.

In soft woods with pronounced grain, there is sometimes a tendency for the hole to wander, due to the varying hardness of the wood.

When a hole is to be bored to a predetermined depth, mark the depth on the side of the stock, then run the bit down so that it is even with the mark.

* The archtop guitar incorporates a top, either carved out of solid wood or heat-pressed using laminations, that is arched like instruments in the violin family, usually with an f-hole rather than a round sound hole.

An electron from the 2s level fills in the 1s hole and the transition energy is imparted to a 2p electron which is emitted.

The central capsule is made up of microfibrils arranged into twenty plates, each with a hole through which one spine projects, and there is also a microfibrillar cortex linked to the spines by myonemes.

Augustus is shown with an aegis thrown over his shoulder as a divine attribute in the Blacas Cameo ; the hole for the head appears at the point of his shoulder.

The largest opening of the pencils, which take part in the reproduction of O, i. e. the angle u, is generally determined by the margin of one of the lenses or by a hole in a thin plate placed between, before, or behind the lenses of the system.

In European casinos, " no hole card " games are prevalent ; the dealer's second card is neither drawn nor consulted until the players have all played their hands.

If the dealer's upcard is an ace, the player is offered the option of taking " insurance " before the dealer checks the hole card.

It is advantageous to make an insurance bet whenever the hole card has more than a chance of one in three of being a ten.

A black hole is a region of spacetime where gravity prevents anything, including light, from escaping.

Around a black hole there is a mathematically defined surface called an event horizon that marks the point of no return.

This temperature is inversely proportional to the mass of the black hole, making it difficult to observe this radiation for black holes of stellar mass or greater.

Two years later, Ezra Newman found the axisymmetric solution for a black hole that is both rotating and electrically charged.

Through the work of Werner Israel, Brandon Carter, and David Robinson the no-hair theorem emerged, stating that a stationary black hole solution is completely described by the three parameters of the Kerr – Newman metric ; mass, angular momentum, and electric charge.

When an object falls into a black hole, any information about the shape of the object or distribution of charge on it is evenly distributed along the horizon of the black hole, and is lost to outside observers.

A porthole on a ship may also be called a sidescuttle or side scuttle ( side hole ), as officially termed in the International Convention for the Safety of Life at Sea.

The course-now officially termed the " Ruchill Community Golf Facility " is now run by Culture and Sport Glasgow, part of Glasgow City Council, and is a nine hole course, designed with Colin Montgomery's input, apparently suited for developing and established players.

In Sequoyah, Oklahoma, Novalee asks her boyfriend to stop at Wal-Mart so that she can go to the bathroom and replace her shoes, which had fallen out a hole in the floor of their beat-up car.

This is why a ballistic pendulum relies on conservation of bullet momentum and pendulum energy rather than conservation of bullet energy to determine bullet velocity ; a bullet fired into a hanging block of wood or other material will spend much of its kinetic energy to create a hole in the wood and dissipate heat as friction as it slows to a stop.

A small hole in the lid is necessary for air access inside to stop the spout from dripping and splashing when tea is poured.

The £ 0. 5 million project involved the provision of a stop lock, a new slipway, an improved winding hole and a wetland nature reserve, running parallel to the canal and connected to it.

Bugs ducks into a hole, and Sam slides off the dragon when trying to stop.

Tampon originated from the medieval French word tampion, meaning a piece of cloth to stop a hole, a stamp, plug, or stopper.

The fishing hole has garnered some of the area's best fishing and is a popular fishing stop during the Owen Sound Salmon Spectacular Derby.

When the fish stop biting where they are, anglers can move to the next hole, checking it with their sonar first to look for activity, and if there are no fish they will keep moving until fish are found.

As MacKenna's group plans to make a final rest stop at a water hole, the cavalry ambushes them.

The episode goes on to follow Booster's attempt to stop a black hole.

During the 1963 Phoenix Open, January had a putt roll up to the lip of the hole and stop.

The tape was read continually and the number in the registers incremented with each hole encountered in their control track until a " stop " instruction was encountered, four holes in a line.

When he announces his intention to hurl Galactus into the black hole instead, the three Elders, who wanted to rescue their brother Elders from within Galactus, threaten him with the other five Infinity Gems to stop him.

Smitty picks up Meade and they hole out for a few days until the police stop looking for the killer.

Wayne and Diane rush outside to make him stop, but unfortunately he does just as the lawnmower is over the hole.

* Stopper knot: A knot tied in the end of a rope, usually to stop it passing through a hole ; most commonly a figure-eight knot.

Collaring a hole is needed to stop the walls from caving in and bogging the rod string at the top of the hole.

A vented gauge pressure transmitter for example allows the outside air pressure to be exposed to the negative side of the pressure sensing diaphragm, via a vented cable or a hole on the side of the device, so that it always measures the pressure referred to ambient barometric pressure.

The esophagus passes through posterior mediastinum in thorax and enters abdomen through a hole in the diaphragm at the level of the tenth thoracic vertebrae ( T10 ).

In this instance the diaphragm abnormality is characterized by a hole in the postero-lateral corner of the diaphragm which allows passage of the abdominal viscera into the chest cavity.
