Raise drilling is used to create large drill holes -- up to 7.6 meters in diameter. The holes, or tunnels, are used to connect mine shafts, power plant tunnels or channels for rainwater and surplus water, as well as for ventilation between different levels in a mine. This type of drilling is performed in two stages. First you drill a smaller pilot hole and then you swap the smaller drill bit with a reamer. The reamer is equipped with reels made of hardened metal which have the same diameter as the final hole. The hole is expanded as the reamer crushes the rock using both pressure and rotation. Raise drilling can be used for holes and tunnels of up to 1100 meters in length, which makes this method very practical for many applications. https://engineers-channel.blogspot.com/p/raise-drill.html

When a precise hole is required in a piece of material a reamer is used, because a drill does not give a very exact diameter hole. This video shows how to use a reamer in a piece of steel. Normally you would drill the hole approximately 0.2 of a millimetre smaller than the reamer that you are using. Brought to you by http://www.ultimatehandyman.co.uk/how-to/table/metalworking/

- Like our Facebook: https://www.facebook.com/oilvips - Geologists and geophysicists have agreed on the existence of a "prospect", a potential field. In order to find out if hydrocarbons are indeed trapped in the reservoir rock, we must drill to hit them. Bearing in mind the knowledge acquired about the substratum and the topography of the land, the best position for the installation of the drilling equipment is determined. Generally it is vertically above the point of maximum thickness of the geological layer suspected of containing hydrocarbons. The drillers then make a hole in conditions that are sometimes difficult. Of small diameter (from 20 to 50 cm) this hole will generally go down to a depth of between 2000 and 4000 meters. Exceptionally, certain wells exceed 6000 m. One of them has even exceeded 11 000 m! Certain fields can be buried at a depth equivalent to the height of 12 Eiffel Towers ... The derrick is the visible part of the drilling rig. It is a metal tower several tens of meters high. It is used to vertically introduce the drill strings down the hole. These drill strings are made up of metallic tubes screwed end to end. They transmit a rotating movement (rotary drilling) to the drilling tool (the drill bit) and help circulate a liquid called "mud" (because of its appearance) down to the bottom of the well. The drilling rig works like an enormous electric hand-drill of which the derrick would be the body, the drill strings the drive and the drilling tool the drill bit. The most usual tool is an assembly of three cones -- from which comes the name "tri cone" -- in very hard steel, which crushes the rock. Sometimes when the rock being drilled is very resistant, a single- block tool encrusted with diamonds is used. This wears down the rock by abrasion. Through the drill pipes, at the extremity of which the drill bit rotates, a special mud is injected, which the mud engineer prepares and controls. This mud cools the drill bit and consolidates the sides of the borehole. Moreover it avoids a gushing of oil, gas or water from the layer being drilled, by equilibrating the pressure. Finally, the mud cleans the bottom of the well. As it makes its way along the pipes, it carries the rock fragments (cuttings) to the surface. The geologist examines these cuttings to discover the characteristics of the rocks being drilled and to detect eventual shows of hydrocarbons. The cuttings, fragments of rock crushed by the drill bit, are brought back up to the surface by the mud. To obtain information on the characteristics of the rock being drilled, a core sample is taken. The drill bit is replaced by a hollow tool called a core sampler, which extracts a cylindrical sample of several meters of rock. This core supplies data on the nature of the rock, the inclination of the layers, the structure, permeability, porosity, fluid content and the fossils present. After having drilled a few hundred of meters, the explorers and drillers undertake measurements down the hole called loggings, by lowering electronic tools into the well to measure the physical parameters of the rock being drilled. These measures validate, or invalidate, or make more precise the hypotheses put forward earlier about the rocks and the fluids that they contain. The log engineer is responsible for the analysis of the results of the various loggings. The sides of the well are then reinforced by steel tubes screwed end to end. These tubes (called casings) are cemented into the ground. They isolate the various layers encountered. When hydrocarbons are found, and if the pressure is sufficient to allow them come to the surface naturally, the drillers do a flow check. The oil is allowed to come to the surface during several hours or several days through a calibrated hole. The quantity recovered is measured, as are the changes in pressure at the bottom of the well. In this way, a little more knowledge is gained about the probable productivity of the field. If the field seems promising, the exploration team ends the first discovery well and goes on to drill a second, even several others, several hundred or thousand meters further away. In this way, the exploration team is able to refine its knowledge about the characteristics of the field. The decision to stop drilling is made only when all these appraisal wells have provided sufficient information either to give up the exploration or to envisage future production. --------------------------------------------------------------------------------------- Like our Facebook: https://www.facebook.com/oilvips Twitter: https://twitter.com/oilvips And Don't forget to subscribe to our channel

In this video, I show you how I reamed the tie rod tapered holes on my Reid Racing knuckles to better fit my tie rod ends from TMR Customs. This is my first time to perform this particular task. It was a frightening idea, but it actually turned out to be a pretty easy job. If you have any tips for the next guy... please post in the comments! Here is the reamer bit I was using: https://amzn.to/2m7QAUN For Proper Fitting of Ball Joints and Tie Rod Ends 1 1/2" taper per Foot or 3 Degrees 34 minutes per side Small Diameter 15/32-Large Diameter 1 1/32" Three Flats on Shank for better Grip in Chuck You can find them cheaper, but I needed this quick. It came same day delivery from Amazon... :-) 🔔 Please CLICK THE BELL if you want to see my videos! 🔔 The JK tie rod end taper is the same "1-in-8" taper (which is also labeled as 1 1/2" taper per Foot) that most other American vehicles use but it has a unique dimension of 0.640" at the small end. The "1-ton" tie rod end is the industry standard for aftermarket steering systems. They're cheap, plentiful, strong, and available with both left-hand-thread and right-hand-thread for easy on-vehicle adjustment. There are also special offset versions available for vehicles where clearance is a problem, such as a diff cover guard or extra-thick diff cover. The "1-ton" tie rod end uses the same "1-in-8" taper as the JKs, but their small-end dimension is 0.650". Reid Racing currently drills their holes to a slightly smaller than stock JK taper (mine were around 0.630 but I don't know the "official number"). -- source of values: Reid Racing

This onsite footage from 02011 shows the completion of the 500 foot deep vertical shaft for the 10,000 Year Clock in West Texas. We used a mining technique called raise boring to create the 12.5 foot diameter shaft. Instead of drilling down from the top, a large diameter reamer was pulled up from the bottom to the surface, starting from a smaller diameter pilot hole. It's more efficient than a top-down drill because the rubble isn't fighting gravity. It rains down beneath the advancing bore and gets hauled out a horizontal shaft at the bottom. Following this work, we began to cut the spiral stairway into the walls of the shaft using a robotic stone-cutting saw as well as the manufacture and testing of the full size Clock components.

Use a gas-powered cut-off saw or angle grinder to cut stone. 2. To hand-split a stone, begin by using an electric rotary hammer and masonry bit to drill holes spaced 4 inches apart across the stone face. 3. Insert a steel wedge and pair of steel feathers (shims) into each hole. 4. Use a hammer to alternately tap each wedge into the hole. 5. Continue to lightly tap each wedge until the stone cracks in two. 6. To split a stone with a hand tracer, set the tracer on top of the stone and tap it with the hammer. Move the tracer down an inch or so and strike it again. 7. Continue in this fashion until you’ve a cut line across the stone. 8. Move the hand tracer back to the beginning and repeat, tap it, move it, tap it, move it, until the stone splits in two. 9. To crack large stones, use a stonebuster tool. Set the buster on top of the stone, then strike it sharply with a hammer to cut a line across the stone. Repeat until the stone splits. 10. To trim the edge of a stone, use a carbide handset. Hold the handset at an angle to the stone, then strike the handset with a hammer to chip off small pieces of stone. 11. Use a carbide-tipped hand point to chip protrusions and high spots off of a stone face. 12. To smooth and even out the surface of a stone, lightly tap it with a bushing hammer. 13. Continue to tap the stone until achieving the desired level of smoothness.

It is toolmaking time. Probably one of the most rewarding activities every craftsman indulges in - as it helps him to economize on production time, without sacrificing the quality of his product. This is about the production of a special tool for the spigot or tap makers of the late Middle Ages. No one knows this tool from finds, nor do the sources tell us anything about it. But there are contemporary pictures. These are the basis for this reconstruction. Archaeometallurgy is more than just finding out from which mine a particular metal may have come from, or how iron was made from bog ore. It does really encompass quite a lot of aspects of a metal craft. Also, a reconstruction of a process or a tool should not only work in theoretically! So, only writing about it is not enough (: This is why I have this channel: My archaeological reconstruction should work in real life as well!

I decided to make custom size dowel pins, only about .010 larger than the stock 5/16” (.3125) holes in the GMC blower case. I did this so I would not have to open up the dowel holes to the next standard size, which is 3/8”, in case I made a mistake in setting clearances, or if I ever had to move things around in the future. This is just my personal preference, and is in no way a superior method over using standard size dowel pins. This just gives more options for oversize pins in the future. The pins are made from O-1, letter “P” (.323” diameter) size drill rod, purchased from McMaster Carr. The part number for the rod that I used is 8893K225 and it is very inexpensive at $6.49 for a 3’ section. If you are a professional machinist and are reading this, you might be thinking “O-1 is not hard enough, or close tolerance enough to use for dowel pins.” Well, if this were a precision steel die, or a part for an aerospace application, that might be true. However, this is not the Space Shuttle. It is a cast aluminum blower case where a very hard pin surface is completely unnecessary to prevent galling during installation. Also, these pins are exclusively for static alignment during assembly and they are under no appreciable shear load while the blower is in operation. The 10 end plate bolts bear all of the shear loads. The only thing that these pins must do is stay put in the bearing plates, and allow for a slip fit into the blower case, and for the front cover. Size “P” reamers can be obtained from any tooling supplier and I was able to get mine off of Amazon for under $5.00, as an add on item. In the end, the select fit item was the dowel pin, the cheapest part of the assembly. Any errors that I would make would be confined to this 10 cent part, and I could always cut another one from my 3’ long rod if I had a clearance or size problem. Although slightly oversize reamers (.3235) can be obtained, they are not as common as standard "P" size reamers and they are more expensive than the standard size reamers. This was another reason why I decided to select fit my pins by using the emery to reduce the blower case section of the pin by about .0005 for my slip fit. If I did this all the time, the $35 oversize reamer would be in my tool box, but for a "one time only" type of job, I elected to reduce the case end of the pins instead. ================================================ Disclaimer: This video series is not intended to be an exhaustive “How to do it” tutorial on how to rebuild a 6-71 blower for Gasoline use.

God does not want us to pay for our sins ourselves (hell) so He made a way for us to be saved by grace. Jesus became flesh (man) and allowed Himself to be unjustly killed on the cross to pay for our sins, He did this on your behalf (and mine as well). After his death He was buried and rose again on the third day. No one is good enough to be saved and that is why Jesus paid dearly for your sins and mine as well. He loves you. You have been given enough information now for you to call upon Jesus to be saved. Be willing to turn from sin and through prayer ask Jesus to save you and then be baptised in His name. Jesus is the only way to be saved and the only way to the Father, call upon Jesus. It's the most important thing you can do.

SOUNDBITE: (Spanish) Laurence Golborne, Chilean Mining Minister: "What we have called Plan A has already drilled 90 metres. For the first time it has completed an entire shift, it has drilled 15 metres in the past 12 hours, reaching the 90 metres. This plan went according to our forecasts. This machine will continue until it reaches 700 metres and then we will have to change the head (to enlarge the width of the shaft) which will take some days. You know they have to do two passes (one to drill the shaft, another to enlarge that same shaft). Then we also have Plan B, the T-130 machine which started drilling yesterday and has drilled 26 metres so far." 10. Wide of mine 11. Wide of drilling machinery 12. Official on site 13. Wide of trucks parked at mine STORYLINE Rescue efforts were continuing at a Chilean mine on Monday to free the 33 men who have been trapped underground for over a month. Chilean authorities are trying to dig a tunnel large enough to free the miners stuck at the San Jose mine in Copiapo, but engineers estimate this could take up to four months. The men have been trapped since 5 August, after a landslide at the gold and copper mine in the Atacama desert caused a tunnel to collapse and entombed the men more than 2,200 feet (67.6 metres) below ground. On Monday, plans to drill shafts 700 metres deep in efforts to rescue the men were well under way, with Mining Minister Laurence Golborne overseeing proceedings. Chile's state-owned Codelco mining company began the heavy drilling on Tuesday, 31 August, using the Strata 950 drill. Authorities have been using a multi-pronged approach to speed up rescue efforts. Golborne said what authorities call "Plan A" had already drilled 90 metres. "For the first time it has completed an entire shift, it has drilled 15 metres in the past 12 hours, reaching the 90 metres. This plan went according to our forecasts," he added. Golborne said drilling would continue until it reached the 700 metres mark, and then efforts would focus on enlarging the width of the shaft. Golborne said "Plan B", using the T-130 machine, had begun yesterday, with engineers already drilling 26 metres. Plan B, a potentially faster method, involves the huge Schramm T-130 drill to enlarge one of the three bore holes that already have been opened. But even the geologists who have offered faster rescue timelines than government estimates acknowledge that technical problems with either drill could slow the process: breaking drill bits, hitting water, or running into areas of extremely strong rock.

How to do-it-yourself tutorial on basic pipe replacement using half inch (1/2") copper pipe and easy to use SharkBite pipe couplings. Transcript provided for the hearing impaired: Today on Repairs101 we're going to take care of something that I've been putting off for a long time. You might remember from an earlier video of mine this leaky elbow here. And we're going to change this leaking elbow here that I discovered way back in one of the very first videos I made. I never seem to run out of things to fix around here. So I've already turned off the water and I've let the system drain by opening a faucet at the lowest point and letting all the water run out through that and then to speed that up, of course, I went up to the highest point and opened a valve up there to let the air chase all the water out. The challenge here, as I see it, is that this elbow is of course attached to this pipe that is going straight up and that is inaccessible. And this end of this pipe coming this way is tied into this tee which makes it also inaccessible. You'll see that when I unscrew this end of this pipe, this end of this pipe get driven deeper into this valve. And therein lies your problem in reassembly. The real problem of course is figuring out exactly how to put this back together again. Taking it apart is easy, I'm just going to cut it with my reciprocating saw right here. If I can I'm going to rebuild this valve right here and if I can't I have a replacement for it. I got some of these great "SharkBite" quick connectors. I got something called "SharkBites". Definitely worth the price for the time you save in making connections. I got them at "Home Depot" and they go together real quick so we're going to use those. Be sure to wear hearing protection and eye protection as I'm doing. [Sawing] [Pops] Oh yeah. There it goes. [Bangs] Whoo! Alright, there we go. That's tricky. OK I got it. [Torching] [Groans] Oh man that was hard. Yeah I used to have this foreman who would say "It doesn't matter how strong you are, it's all in the funny noises you make". Alright, I got it. [Sizzles] It's still very hot. You can almost hear it sizzle -- well I can hear it sizzling, I don't know if you can hear it sizzling. There you go. Stem valve, just like the ones in my earlier video and there you go, we'll just change the bushing on that real quick and I can put those back in service. OK here's what a really bad looking valve bushing looks like, it's completely dried out and it's going to take quite a bit of digging to remove it. Take it apart, clean it out, put in a new bushing and reuse it. New valve like this is about seven or eight dollars Canadian. One of these valve bushings is only a few cents. I'm just going to drop that in there. Then spin the pipe out. Clean up these threads. Make sure you're wearing your eye protection when you do this kind of work. Now this is the point in the repair where a lot of guys will reach for their Teflon tape or silicone tape. I was trained not to use this stuff. As far as sealing pipes go I use pipe sealant. Here's "Oatey" brand, and that's what I use is "pipe-dope"; "pipe joint compound". Now the reason is because mechanics have to consider that in fuel systems, the Teflon tape breaks down and it enters the fuel system and then it can get into things like the fuel injectors and plug them up and cost you a lot of money. I'm just going to slip in the SharkBite now, got the threads on that all doped up, there we go. There we go. Cut your pipes using a pipe cutter like this one, don't kid yourself about a hacksaw. You're not going to be able to cut them square using a hacksaw. This is the only tool for the job. There we go. After you've cut it you want to ream the burrs out of the end, that's what that little triangle sticking out of your pipe-cutter is for. It's to ream the burrs out. So you want to do that. Make sure it's nice and smooth and clean. OK I'll just clean up the end with some sandpaper. Make sure it's nice. Nice and clean and ready to go into those Shark-Bites. That one's good, this one... I'll give it a reaming. And we're nice and clean, ready to go in. So the last stage is make the connection between the two. Now you're going to make a one inch deep connection into these Shark Bites until you hear a click and there it is right there. Now this side. OK bam, that one's done too. And that's what it looks like. Pretty good, eh? Pretty quick, pretty easy, pretty good. No leaks. I like that part.

The Roughneck rock hammer was literally born for directional drilling. Other rock hammers are just posers by comparison. Sure, you can take a vertical mining hammer and stick it on a directional drilling rig. But that’s like trying to rock out to a waltz—no matter how hard you try, it’s just not the same. The Roughneck, on the other hand, was born for this. Give us a call, and let us show you how hard it can rock.

After the pipe exits the pilot hole from the drill on the return, these 30' sections of the drilling stem are being disconnected using a swivel assembly and clamp looking machine called a back reamer that makes sure the pipe doesn't rotate. The sections are removed and being loaded back on the truck. This video is of an HDD (Horizonal Directional Drill) in Jefferson Davis Parish Louisiana under Burwick Bayou performed by R.E.M. on November 20th 2008. This project is a 42" pipeline being installed by Latex Construction that stretches 132 miles through Louisiana. The work in this video is being performed by R.E.M., who is subcontracted out for the Directional Drills on this project. And they Rock.

Mattracks aluminum casting repair, using the tools of the trade; inside & outside micrometers, dial calipers, scales and such, to create a jig for holding the castings while the machine work is being preformed. Mattracks Part 11; is the finishing steps on the machine work needed on the link assemblies, facing, drilling and reaming of the links. I had a glitch in my DRO and It was about a week ago during a heavy solar flare activity, which I didn't hear about until later in the day. Did anyone else have a mishap with their DRO and then clear up after a reset / restart? I know of three others in the area was just wondering how much of a spread the effect had or was it coincidence?

What is CHURN DRILL? What does CHURN DRILL mean? CHURN DRILL meaning - CHURN DRILL definition - CHURN DRILL explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. The churn drill is a large drilling machine that bores large diameter holes in the ground. In mining, they were used to drill into the soft carbonate rocks of lead and zinc hosted regions to extract bulk samples of the ore. Churn drills were invented as early as 221 BC in Qin Dynasty China, capable of reaching a depth of 1500 m. Churn drills in ancient China were built of wood and labor-intensive, but were able to go through solid rock. The churn drill was transmitted to Europe during the 12th century. A churn drill using steam power, based on "the ancient Chinese method of lifting and dropping a rod tipped with a bit," was first built in 1835 by Isaac Singer in the United States, according to The History of Grinding. In America, they were common in the Tri-State areas during the lead and zinc mining in Missouri, Oklahoma, and Kansas. There is an example of one of these machines at the Northern Life Museum in Fort Smith, Northwest Territories, Canada. It was used in 1929-1930 at the Pine Point lead and zinc mine in the Northwest Territories.

Immediately following our season-ending trip to CDLC, I flew out of San Antonio to Durango on Sunday afternoon for work. I needed to deliver4 3/4" PDC drill bits to a rig south of the Airport in the small tribal community of Ignacio because of an(other) AWOL field bit hand! After my last whirlwind trip in September, I decided I wanted to make the most of my few days in beautiful SW Colorado!

Victorinox Farmer: http://amzn.to/2zCwUQO The Victorinox Farmer pocket knife has the excellent looking Silver Alox Ribbed handles, which make for a very slim knife. The design is very eye grabbing, especially comparing it to the typical red Victorinox scales. The tools are simple, but highly effective. The standout tool is the Reamer - which creates a perfectly round hole in wood and also other similar materials. I even used it to drill out a lanyard hole in my Mora Bushcraft Knife. The typical bottle and can opener is included, as well as a standard flathead screwdriver (which has a wire stripper on it). The straight blade has a 2.5" cutting edge on it. And last but not least is the wood saw. I have used mine to saw through 2-3" wood branches with no problems. It definitely will not replace a dedicated wood saw, but it certainly will get the job done if it is all that you have. The drawback for me was that because of the slim scales, there is no tweezers or a toothpick. However that is a small price to pay for such a great knife. I think this would make a great companion knife for hiking, or even a great EDC knife. Thanks for watching, be safe, and Peace! Filmed with Canon SX230 HS camera.
