We Built a 3m (10 ft) MEGADRILL That Weighs 20 Tons! (Here's How It Works!)

[@halheavyduty]

I can’t believe I forgot to say it! The holes will be used for underground mining ventilation.

[@michaelcook9422]

Wouldn’t it be cheaper and easier to drill multiple smaller holes with existing tooling rather than one enormous one with brand new custom tooling?

[@xuejiaoxu6778]

Would make short work os septic tanks aswell 😂

[@kerrysullivan6294]

That was my question, thanks

[@ericpatterson3887]

​​@@michaelcook9422being in the construction industry my whole life in a family run business I think the reason for the one large hole would be less time than multiple holes. While the fab work, labour and materials for the large drill are significant, they will have gained the ability to do shafts like this in the future thus adding a new capability to the arsenal. The cost per hour to run the rig and pay everyones hourly wage to run the rig is pretty darn expensive I'm sure! As well as set up time every time you move the rig is probably quite lengthy as it is not just the rig that needs to be moved, all of the support stuff needs to be moved as well, like generator(s), compressor(s), and the drill rods and bits, at least any that are not carried by the rig itself which usually is not much due to transportation weight. Just setting up the rig stabilizers and any counter weights can be time consuming. Sinking this type of shaft is not like drlling a well. It is a bit different. Not only that, Matt mentioned that in addition to ventilation the shaft is also a rescue shaft and emergency exit shaft. While I can't speak for Matt obviously, I'm pretty sure these are at least some of the reasons for sinking a single shaft.

[@mikepaul3959]

@@michaelcook9422 Maybe because (for example) a pipe with a 2-inch diameter will have four times the volume of a pipe with a 1-inch diameter, assuming both pipes are the same length. So it would take a lot of smaller holes to equal the volume of a big one??

[@halheavyduty]

It’s wild to walk through when they’re all going at it. I reckon you’re right though. Probably a full metric ton of wire in there. Most welds on the MEGADRILL are 6 passes or more!

This is just fascinating to watch. Especially if you have never seen this type of drilling set up before. I remember as a kid back in the sixties seeing picture of oil drilling cutter heads and if memory serves me right they were between 6"-8" in diameter. Maybe a bit more. So in comparison, well there's no comparison really is there? lol I've watched a couple of these now and subbed after the first one, I love to watch any sort of metal fabrication and machining processes, especially those with manual operation of machines, but I'm blown away watching the CNC stuff here.

[@halheavyduty]

Cheers mate. Yeah, most of our holes have a 7 5/8 - 8 1/2” drill head with 3” drill rods. To send a 10 foot drill driven by a foot wide drill rod (that weigh a ton each!) is mind boggling. My dad runs the drilling side of it and is a true genius at what he does. In the literal sense. His problem solving ability is insane.

[@ericpatterson3887]

Great video Matt! I was soaking up all that info. I know some probably won't be as keen on this kind of format,and are looking for just the machining and fab content, but I think it is a very good idea to occasionally bring this type of format for us nerds who like the technical side of things. Giving context to what you are creating really enriches the content, making it more engaging which makes it more enjoyable. Kind of like building a plot in a story, making the content have depth and more real, instead of just something seen on a video. While there are some things that could have been better(you don't need me to point them out, as it is obvious you are passionate about being a content creator, and as such I'm sure you are your own worst critic) the editing was pretty good! Plenty of good camera angles to work with, and the flow was good. It may be useful to do what many people in movie and tv do by making a story board (a white board or a piece of paper works) and layout the main points in the narrative and the video content and place them in the best order to get a nice flow for a pleasant viewing experience. You might have already gotten some similar advice from Karen, or are using this method or similar already because your editing is pretty good already, and in this episode it was quite good. Keep it up brother. Thanks for putting yourself out there and taking us along for the ride. It's very interesting and entertaining. Oh, and the dog content is a nice touch, hard to go wrong with that! Cheers from Phoenix!

Very interesting Matt. PCD is the correct name for the inserts. I used to promote for machining non ferrous materials and it certainly has great wear resistant properties. I would say there is a lot of dollars tied up in them. Cheers Ian

To my knowledge PCD refers to the material the cutters are made of (polycrystaline diamond). PDC is the correct name for these cutters (polycrystaline diamond cutter) when used on a drill/core bit :)

I’m just really grateful for all the encouragement and support in the comments. I genuinely think we do some cool stuff in the shop, and am glad others find it interesting too :)

[@johnallen4793]

I work for several other streamers but not the same type of content (Robert Gouveia - "Watching the Watcher" and Viva Frei, both political commentators, and a few in various parts of the world doing some minor fabrication and other things like cabin building). So in the last video you said you wanted to hear from us and hears my thoughts... My take on this and the last several videos is that I like these. 💯❤️ On this video, yes there is a lot of commentary but it was done well in conjunction with good fabrication footage. In this video it was needed and done well at a good pace. Personality (and it really is only a preference) I suggest keeping the same amount of commentary but try to get a bit more of the fabrication in which will make slightly longer videos (about 35-40 minutes in total) but that's ok as long as the commentary doesn't increase too much.🙏🙏 I personally get really caught up in the fabrication and don't mind them being longer as they pass really fast. As far as the commentary, it's really helpful and informative (especially in videos like this where we learn so much information ❤) yet as mentioned above adding a bit more fabrication footage in the video to give people's minds a chance to absorb the information. You've mentioned CEE before, and they do a good job most all of the time, although sometimes some footage is left out that I think should have been included. Like CEE you could possibly use time laps more if footage becomes too long... That is definitely where Karen excels as she has found a way to beautifully blend in time laps, sound and timing. 😍 Lastly there will always be people unsatisfied with a YTers format. That's just what makes us all different so just keep up the good work and don't take us too seriously (including me 👀😅😅). So as a wrap up, I'm extremely impressed with your quality of your YT videos (and absolutely impressed with your quality of craftsmanship and quality work 💯👏👏). My suggestion are meant to be helpful and of course it's always nice if the format fluctuates giving diversity to watch. 😃 Have a great day))

[@halheavyduty]

Thanks so much for the detailed feedback mate. Really insightful and very helpful. I’m glad to hear you reckon including more of the uninterrupted machining / fabrication is a good idea. Personally I like to be told what’s going to happen, and then just enjoy watching it happen. But that’s just me

The only thing I can think of is mine vent tunnels with whopping great air coolers forcing cool air into an underground mine. Mount Isa maybe or Cloncurry? That's my guess. Super impressive build.

[@halheavyduty]

Very good guess mate 👊😉

[@chrisoakey9841]

Have you considered using air rams to press the outer wings outward so when finished springs return them so the drill head is smaller than the hole it drilled. You could print a liner to the hole as you go, but still pull it out by shrinking the head before drawing back. All this would allow to go deeper like a TBM pushing on your casing.

[@halheavyduty]

It has been considered. I’ll ask why they didn’t do it. Great question. It’s one for the big guy.

[@roninspoon3935]

Hi Matt.A question from a Boily, What grade of steel are the bits fabricated out of QT 80 or better? Love the work of you and your team

[@halheavyduty]

It’s all out for 4140 & 4340 steel. Welded with ER70 wire. The ER110 is to brittle, but we’ve had good success using the slightly softer wire. More forgiving… We haven’t had any break off yet, so it seems to work. And provided it’s preheated properly etc.

[@GHOSTINPLAINSIGHT]

Once the vent hole is drilled, do they line it with anything?

It gets liked with 18mm thick steel casing. It’s a mission to fab the casing - you can’t just buy it that big. It’s gotta be rolled and welded in segments!

[@davidholmes3323]

Are tey used for underground coal mines? If so, how high is the risk of spark with compressed air and coal seam gas?

[@old2ply29]

Awesome! How much horsepower does it take to turn that huge drill?

[@halheavyduty]

I’ll find out and let you know in the future video. It’s calculated in Nm of torque… and it’s a LOT. 4 x more powerful than our next biggest rig.

[@Sam2-ex8ty]

The top drive on the big rig is designed to produce 100,000 lb-ft of torque at 15RPM. That works out to about 285hp output. The HPU engine has about 500hp available in total.

[@ColinLennard]

Thanks Matt. That was time well waisted - for me very enjoyable. There ie big & there is just tearing the ass out of it. This hole that you are going to make - what are they going to look for? I only say the answer when I posted. The mine - what are they mining?

[@halheavyduty]

Usually coal mining. The ground is soft enough for this bit to work. You’d need a hammer or rock roller in Western Australia, but the giant PCD bit will work in Queensland.

[@halheavyduty]

All at the client request as far as I’m aware. I’ll find out and let you know in a future vid

[@rs2024-s4u]

It's difficult to imagine the drill rig connection to the pipe being capable enough to deliver the amount of torque needed to the drill head without destroying the pipe-rig connection or twisting/destroying any of the coulpings connecting the pipe sections to actually make this work in the field. Just supporting the weight of the drill and pipe to keep from appling to much force to the drill head is amazing.

[@halheavyduty]

It’s a truly crazy setup. I’m really looking forward to catching the footage in the field!

[@rs2024-s4u]

How much does each cutter head cost before installed in the drill?

[@halheavyduty]

Im not sure, but I think the buttons are about $40 or $50 each (last time I checked) Will find out though

[@dwjr5129]

So do you have in-house engineering that designs this crazy stuff or are you working off of a set of somebody’s plans?

[@halheavyduty]

We design it all in house and get it independently drawn up by engineeers who certify it. We are very “field experience driven” … but always get the engineers to run the numbers to make sure it’ll hold

[@hx520w]

Is there engineering and simulation work that's done for parts like this, or is it experience based?

[@halheavyduty]

Both. Generally we have a “field first” approach. We use experience, give a rough design and then the engineers check / improve / certify it. Seems to work well so far. Great question by the way.

Why type or types of rock with they be drilling through?

[@halheavyduty]

I’ll find out the exact terrain closer to the drill. When we do the final site video we’ll get to see exact samples of what comes up ✌️👍

[@StevenStyczinski-sy8cj]

Interesting technology. Grind it into dust and then blow it out. I want to see how it handles cobble size rocks and a little water and Clay?

[@halheavyduty]

It just chews it all up and Hoovers away. Will be good to see

[@StevenStyczinski-sy8cj]

I hope it works as advertised. It probably will. I have confidence they have done their homework. It’s just I have seen such things.

[@halheavyduty]

Only one way to find out. Just send it 💯👊

[@toddhazell925]

Should do a "Crocodile Dundee"! That's not a boring head, this is a boring head...

[@halheavyduty]

Hahaha 💯

Is this going to Oak Island ?

[@halheavyduty]

Treasure island here we come!

i dear you to use that pcd drill on the hulk xD btw is there a reason why they used compressed air over just good old plane water ? ( pass from the shear volum of water they would need ) and i can easily understand why then need those stabulizers for the drill in the whole. just look at it this way. you take a long peace of wire. put one end in a vise and the other in a hand drill and spin it. with how long the wire is compared to its length its gonna wip around like a mofo without support. specially since its onlt the head part of this drill that have wall support and in 3 year you probably have crossoer sub with a iner hole that have fit 2 of the upcomming one that bigger then the hal 316 standing side by side with space to spare xD

[@halheavyduty]

Haha. True. We are designing the bigger thread now and it’s going to be bloody MASSIVE. Yeah… I need a bigger boat. Something about twice the size of the hulk with CNC & Manual would be awesome. Thinking of a Dainichi. Those lathes are insane

[@flikflak24]

@@halheavyduty why not one of those lathes that you saw me use in my video that i linked you to some time ago ( it might top out at 400 rpm. bit the amouth of power it hald in would probably take the holk lathe and snap it in two without to be able to see it on the load meter. same for its tools so long that you dont take the hulk and put it on its longest side it could probably also have it in its swing over the bed not gonna lie ( the limits is not the machine for the tool themself ) most crazy thing is that. thats not even the big powerfull one out of the 3 lathe's. the big guy is about 40% taller. 60% wider. 210 % longer and about 400% more power/torque do it its gearing then the one you see in my video

[@halheavyduty]

Jeeeezus! Yeah I saw it and that lathe is insane. Some SERIOUS power there. It’d smash the hulk and not even realise it 🤣💯

[@flikflak24]

@@halheavyduty yep. and the one you saw is only the midle size lathe. the big one can take that one and smash it without realiseing it ( it have a 3 step latter just to reach the controle xD and the 4 jaw chuck itself is about ø2200 )

[@halheavyduty]

Love it!!! What a beast

[@johnbishop9245]

what are the holes drilled do?

[@halheavyduty]

Mining ventilation shafts mate 👍👊

I was just going to ask how the rock chips get removed. It seems like it's going to need lots of suction to get all the material out from the cutting face.

[@halheavyduty]

I shouldn’t have used the term “Hoover out” 🤣 Technically it uses compressed air at about it 200PSI to push the cuttings up the internal pipe. Seven big compressors worth of air.
