An ancient bow drill is device that looks like a bow with a string. A piece of wood with a point is spun at high speed using the bow and string to drill a hole, usually in wood.

It is a rod called the Kelly or Grief Stem.

A collar clamp on a drilling rig is used to secure the drill string during operations, particularly when making connections or changes to the drill string components. It helps to stabilize the drill string and prevent it from falling or shifting, ensuring safety and efficiency while drilling. Additionally, the collar clamp facilitates the handling of heavy equipment and minimizes the risk of accidents in the rig environment.

Weight of drill string while going in the well

Drill pipe slips are specialized mechanical devices used in drilling operations to secure and support the weight of the drill string when it is being lifted or lowered into the wellbore. They are typically made of metal and feature serrated teeth that grip the drill pipe, preventing it from slipping or falling. Slips are essential during tripping operations to ensure safety and maintain control over the drill string. They are usually part of the drilling rig's rotary table or a similar assembly.

A tool commonly used to latch onto the drill string while hoisting or lowering drill pipe is called a "pipe ram" or "pipe wiper." This tool is typically part of the blowout preventer (BOP) system and is designed to create a secure seal around the drill pipe, allowing for safe and efficient operations. It helps prevent the escape of fluids and maintains well control during drilling operations.

The term "tripping the well" got it's start most likely as a reference to the "round trip" made by the drill bit. The first leg of the trip is coming out of the hole, by lifting the entire drill string and unscrewing the upper most drill pipe called a joint, the newly removed drill pipe is laid beside the rig and the drill string is lifted again, etc. until all drill pipe is out of the hole. After service work is performed, for example change to fresh drill bit, then the second leg of the trip is to reverse the process, lowering the drill string as each new joint is made until fully back in the hole with the bit on bottom. You can find a lot of interesting videos on offshore rigs, jobs, etc here:

I left the previous answer in place:

When drill pipe is lowered or put into the well in the well, it is called running in or is tripping into the well. When drill pipe is raised or pull out of the well, it is call running out or tripping out of the well.

To calculate a drill string, you need to determine several key parameters, including the total weight on bit (WOB), the tensile strength of the drill string, and the friction losses. Begin by calculating the total length of the drill string and its weight per unit length. Then, use the appropriate formulas to assess the tensile load and any potential buckling or torsional forces. Finally, consider factors like fluid properties and wellbore conditions to ensure optimal drilling performance.

simple option: take a string, wrap it around the tube, cut off extra, measure the string. Divide by 3, use a ruler to mark the 3 spots on the string, wrap back around tube, and transfer the dots to the tube. DRILL!

Accurate option: find circumference of tube. (you can find this by measuring the diameter of the tube, multiply that by PI) divide by 3, mark a starting point, drill holes offset by your length.

Rotating weight in drilling operations refers to the portion of the weight of the drill string that is effectively transferred to the drill bit while it is in motion. It is calculated by considering factors like the total weight of the drill string, the buoyancy effect of the drilling fluid, and the friction encountered during rotation. This weight is crucial for maintaining optimal drilling performance, as it influences the rate of penetration and the ability to break rock. Proper management of rotating weight helps to enhance drilling efficiency and reduce wear on the drill bit.

A glass drill or diamond saw

To drill with a cable tool rig, the process begins by setting up the rig and securing the drill bit on the end of the drill string. The rig's mechanism raises and drops the heavy drill bit repeatedly to break the rock or soil. After each drop, the bit is rotated slightly to create a circular hole, and the cuttings are removed by a bailer or by flushing with water. This cycle is repeated until the desired depth is reached.

Recruits in boot camp are generally fearful of their drill sergeant.

The brilliant young police detective was promoted to sergeant after solving a string of crimes.

To attach a string to your door, you can use a small adhesive hook or a piece of tape on the door's surface. If you prefer a more permanent solution, drill a small hole near the edge of the door and thread the string through it, securing it with a knot. Alternatively, you can use a door handle or knob to tie the string around. Ensure that the attachment is secure and doesn’t obstruct the door’s operation.

A drilling rig operates by using a rotating drill bit to penetrate the earth's surface and reach underground resources, such as oil or natural gas. The rig's structure supports various components, including the drill pipe, which connects the surface equipment to the drill bit. As the drill bit rotates, drilling mud is circulated through the system to cool the bit, remove cuttings, and maintain pressure in the well. The rig is equipped with mechanisms for hoisting, lowering, and rotating the drill string, allowing for efficient drilling operations.

Well, personally I think that there are plenty of ideas. But since your looking for an interesting one, I have a few.

Directions: (You will need any type of coin, string, yarn etc. scissors, and a drill.)
1. Get any type of coin, (Quarter, nickel, penny, dimes, etc.)
2. Get your Dad, Mom, or you if you are at least 13 and are supervised at the time.
3. Take out a drill.
4. Put the coin on a table.
5. Take the drill, and drill a hole close to the top but not close enough that the hole will break.
6. When the hole is there, put string, yarn etc. through the hole.
7. Make sure the string, yarn etc. is long enough so it can just slip around your neck when you tie it.
8. Tie the string, yarn etc. in a double knot.
9. See if it can slip around your neck. (If not, cut the string, yarn etc. off the coin and start at step 6.)
10. Enjoy your necklace!

If this did satisfy you, use one of those jewelery making kits. I will have more ideas for you soon! Hope this helped!

you can drill holes for the string in just about anything (ive used wooden furniture casters)for the top or just wood. and beads or anything you like that you can string on it. use bamboo rods or aluminum or copper pipes(need pipe cutter and drill) for the chimes.

One would need a few things to repair a guitar at home, though this would depend on what needed repairing. If one had a broken string one would need a replacement string. A drill bit may also be needed.

Hydraulics.

They are used for oilfield drilling operations and widely applied in making up and breaking out of drill pipes. They are designed to be open-throat with high mobility to escape from the drill pipes freely. A drill pipe power tong consists of a spinning tong and a torque tong, it substitutes a cathead, suspension tong and spinning rope in making up and breaking out.

In Eterna City there is a man that gives you an Explorer Kit and a string of tasks. Once you complete these tasks you will be given a Digger Drill. Go into the Underground where you want your secret base to be. Face a wall and use your digger drill. Note that they are in the Trap poket of your bag, not the Goods or Treasures pockets.

A drill machine can mean a hand held electric drill, or a bench drill press or a pillar drill.

well in a telephone box you can use money (drill a hole in it and tread it with string to get a free turn) that's a weakness, the strength is that it is hard to rob and probably protected by a camera.

The Mohawk Indians made their money from shells or cockles that they found on the beach. They would drill holes in the middle of these little bones and attach them to string.

Oil rigs use a drill to penetrate the seabed and reach the oil reservoir beneath it. The oil is then pumped up the drill string to the surface where it can be collected and transported. Additionally, some oil rigs have pipelines that connect to oil storage facilities on land for further processing and distribution.
