[@dwjr5129]

Not being a machinist I’ve learned a lot about the skills you guys have watching several channels. Particularly your attention to detail . However, watching you machine these big parts has taught me that the most important skill is probably patience. Without it I think you’d have a bunch of destroyed parts and machines at the end of the day. Very expensive parts and machines.

[@halheavyduty]

Patience is definitely the key. I’m regularly reminded… “You’re only once digit or decimal from disaster… take your time and DOUBLE CHECK” And go very slowly on the first run. That’s said… once I’m sure it’s running correctly, we pretty much aim for 60-80% max. And on the odd occasion… You’ve just gotta send it 🤣

I worked for a short time at Demag Delaval Turbomachinery in Trenton, PA, USA. Was running a G&L CNC VBM with a 6 foot table. I'd never run anything that big before. I was machining gas turbine impellers for pumping natural gas. Got one on the table, 5 foot diameter or so, reworking an o-ring groove that was brazed up after being cut too wide. That was nerve racking, tickling a few thou off a gazillion dollar part. Indicated the part in with 4x4s and a sledge hammer. The good old days.

Engineer in the United States. Love watching manufacturing vids. It lets me know what troubles I cause y'all machinists. 1 question. Do y'all ever penetrant inspect the parts before they go out into the field? I'd bet a small crack could become a big problem with the forces involved there

[@Celciusify]

Machinist here, what frustrates me most is when an engineer has no idea what he's asking for, and thinks the world works like in his computer. Recent example; Drawing called for a 25H7 thickness of a plate, material delivered was ~25.1mm. What he actually wanted was a flat plate, but he didn't know the symbol for that. We worked around it by adjusting the mounting points, sand blasted the plate to a satin finish and he was overjoyed with the fit and finish. Same engineer wanted a bearing surface to be ground, with an Rz of 3.5... I've also dealt with engineers that demand the strictest tolerances and then never measure it and simply judges the quality by how shiny it is.

[@Sam2-ex8ty]

I can't speak for the drill rods, but all the structural components on the big rig were built from steel with mill material test certificates and welds were mag particle tested after fabrication

Nice vid as always. One issue I see with the kraken is the length of the pilot drill.

15:57 While pecking you punch the drill against the part with rapid. It stops right where you were before a peck. This is most probably why the front gets damaged too early. It may be programmable with a clearance where you rapid 0,5mm before feeding in. This may increase the tool life.

[@pst3615]

I've been wondering why nobody drills a pilot hole before using large diameter twist drills, I know that small twist drills may wander off, especially when drilling deep holes, but I think a pilot hole takes away a substantial part of the forces needed to push the large twist drill in the material. I remember my teacher kicking me in the behind (back in my days this was still allowed 😂) when I didn't use a small drill to start any hole larger than 12mm, but hey, times have changed. In drilling we used the saying that you've got to be able to peel a potato with an ax, maybe this is also a part of it 🤣🤣

[@halheavyduty]

If I’m standard drilling, I def ageee with your teacher. The pilot hole should be the thickness of the twist. About 10mm for a 50mm drill etc. It makes a massive difference in the force required… especially when you have to wind the bloody thing in by hand 🤣

Interesting. I was always told to put a small amount of oil on that particular diamond wheel. Could be wrong? I’ll look into it. Cheers brother 👊

[@rixogtr]

@@halheavyduty Could be. I'm not saying you did wrong, it's just what I read and I myself use it dry. Honestly, this claim would kind of make sense for the resin bonded diamond abrasives as the oil could work its way into the resin and debond diamond stones. At least that's how I see it. But I definitely want to put an emphasis on the Drill Doctor products. They do look extremely flimsy and plasticy but the work really well. Depending on a model there's multiple collet holders for a range of sizes of drill bits. I can relate because you do what I used to and while it's a great skill to have to be able to sharpen a drill bit, the semi mechanised way of doing it with the Drill doctor just gives night and day results compared to hand sharpening. The one I got can even do a split grind.

Why do you not relieve the web, to extend the cutting edge in the centre of the pilot drill for the Kraken. I see the centre of the hole is burnished by the blunt nose of the pilot, and so I wonder if it is deliberately to prevent the Kraken from advancing too quickly?

[@halheavyduty]

The Centre drill you had to sharpen, did you consider using an indexable carbide drill there instead for your centre. It might reduce your loading%. No sharpening just index the inserts when needed. Good vid😀 M

It’s funny, but most of these big drills use a HSS centre drill. I asked the same question, but they tend to last longer, and as the surface speed is quite slow in the center, there’s no real need for carbide.

Well spotted mate. In this instance there was some minor chatter. It does happen from time to time as the inserts wear. We just leave it… it’ll be coated with grease and grime in no time. These particular threads need a small “crap gap” to allow for all the rubbish that gets caught up during drilling anyway. If you make them too tight it’s a nightmare in the field.

Why don’t you use a higher feed I mean it’s higher then everything I used but other people like Abom79 is using 0.762mm per rev is the machine not capable of those feeds and amazing video nice seeing some milling on this Turing channel to is that holemaker coolant premixed with water in those container or is it just the oil and you really must be paying a lot of money for coolant since so much turns into mist and how much power has the hall lathe that it got stopped by that enormous drill and how much load can the z axis produce I also Imagen you run the kraken at 0.07 mm per rev because of the HSS drill bit

[@halheavyduty]

Great questions as always bro. 1) Pink lemonade goes in straight and it mixes in the tank. We check it periodically with a refractometer, but mostly by colour… which is surprisingly accurate after you get an eye for it. 2) Hal has about 20kw of power, but the major limitation is Z axis thrust. We are doing work way bigger than what the lathe is designed for, so I just make do. I’ll have to check the exact Z axis stats, but it’s good for up to about a 78mm Udrill… then it struggles. Ideally I want to upgrade to a CNC Megabore with about 50kw and unlimited Z axis…. And about a 420 spindle bore for all the big work that’s coming. Hal does the job for the moment, so no run… but I really want a MEGA set up for the super heavy duty stuff.

[@beriklelmut1842]

@@halheavyduty 20kw is quite strong the strongest lathe in our apprentice workshop has 8KW and a mega cnc would be amazing would love to see a even bigger machine hogging away metal because of a great operator

Great video, though I would like you explaining more what is going on The machining gets a bit repetitive so a voice over will make it more interesting

[@halheavyduty]

I’ll try to get more balance. I’m aware I tend to talk TOO MUCH… but I do think things need explaining. Appreciate the feedback mate. Very much. It helps me improve the vids immensely

Nice diamond sharpening set up, I'd offer to sharpen it for you but I don't think it would fit in my $90 knock off Drill Doctor

🤣🤣🤣

[@RicksterX-92fs]

I have a question. Why don’t the steel manufacturers make steel pipe to a certain rough spec so you don’t have literally drill out that massive amount of material from the center?

[@Mokkisjeva]

Making pipes is a different process which often fails to meet customer criteria when it comes to material specs. Also, even if you get pipe which is at spec the price is usually much more than the time it takes to make a hole yourself. What is cost effective is to just have a specialized shop for drilling to make the hole for you. But those are rare, and depending on distance it might not be worth shipping the material for this process alone.

[@CothranMike]

@@Mokkisjeva And DOM (drawn over mandrel) might not be rigid enough for some uses. Billet steel is still the way to go for strength of materials and specific uses.

[@halheavyduty]

We can order in hollow 4140 from overseas, but Australia only supplies solid billet steel. The steel needs to meet VERY stringent quality standards considering the application. Hope that answers the question. Boy I wish we could buy hollow 4140 locally. It’d halve my workload

[@RicksterX-92fs]

@@halheavyduty I see! Thanks for the response. Well, I guess you keep drilling and I keep watching!

[@gregc1775]

Hi Matt Always watch your videos In your last video, why did you tig weld the head onto the large boring bar instead of MIG or stick welding it on???Greg NSW

[@halheavyduty]

It’s less likely to crack. Honestly it makes marginal difference, but I prefer them TIG welded on.

[@ColinLennard]

Thanks Matt

[@halheavyduty]

Cheers Colin!

[@mrMacGoover]

Your granddad started working on a drilling rig when he was 14?!!😳

[@halheavyduty]

He legit did. His family had a little farm in north west Canada and were so poor he walked off the farm and got a job on a rig by sitting at the local post office. Ended up drilling in the arctic circle for GSI, went to drill for oil in Lebanon in the 50s and eventually landed in Australia in the very early 60s and started a drilling company that’s still going today. A very clever, humble and hardworking man.

[@mrayco]

I'm new subscriber and I'm really interested to the coolant you use on the lathe machine if I may ask what is it and what is it called,,thank you for the brilliant content ❤

[@halheavyduty]

Most welcome mate. Glad you enjoyed it.

Cheers brother 👊

[@ChrisMaj]

7:03 What's the HP on that thing. If your spindle load is below 100%, you're going to slow. 😉

[@halheavyduty]

Hey mate, you’re the PERFECT person for this question (I hope you respond bro) How fast would you comfortably run a 320mm billet with a steady? You do giant parts, so I’d love to know. I absolutely want to try and run it all harder… but I do get a tad nervous when I’ve got a tonne spinning in the lathe. Would love your input bro. Keep up the amazing videos. I always look forward to seeing them.

[@ChrisMaj]

@halheavyduty Hard to tell. I don't know your lathe, I don't know ridgit it is and how much she can handle. I don't think you can find one video me machining in steady rest. I use it for long parts, but that's about it.

[@halheavyduty]

Thanks for taking the time to reply Chris. Appreciate it mate 👍

[@shawnmiller645]

Have you guys ever considered a trepanning setup instead of boring out a 130mm+ hole? If you use 19mm inserts on a 130mm hole, you would cut half of the material by surface area, and save yourself a 92mm bar that you could potentially reuse somewhere else, or sell back to the supplier. And you wouldn't have to do a pecking operation either. Link to example video: kzbin.info/www/bejne/fn6maXyMeLKSfqs

[@halheavyduty]

We’ve got one that’ll pop up on the next video. It just isn’t long enough to do this particular job. Big fan of trepanning. We just need to build a bigger tool ASAP 👊 Cheers brother. Appreciate the comment

@@halheavyduty actually I looked it up .. kennemetal makes a through hole pilot drill for that thing. HTS DFT I think? That or modular. Modular would be more fun but definitely expensive.

[@jmazoso]

Is 4140 the typical steel for the drive subs for augers? Wouldn't you want something less hard?

[@halheavyduty]

All our crossover subs are 4140. You can’t weld it (well) but it is the ideal material for drilling. Hard (but not too hard) If we use milder steel the threads are destroyed in a few holes. Great question by the way.

[@fingerbear3537]

I see that you are using a deep hole drilling canned cycle

[@halheavyduty]

Well spotted. I’ve found it works pretty well for The Kraken. Most Udrills I just run a simple G code program
