[@paulkimber2468]

Hi Paul Kimber here from the UK again, loved the way you had to make the tools to do the job. When I first started as an apprentice in the dockyard in the 1950s we never had carbide tipped tools with the throw away / changeable inserts. It was all HSS and Stellite and grind your own !! . When the first carbide blocks came along that you brazed on to a mild steel shank and then ground the tool, it was a revolution. Cut machining times and tool wear right down it was a mighty leap forward. Inserts and the use of CNCs have taken machining to a new level and love your channel and the way you are pushing the boundaries all the time. Loved the way the beast was singing to you as it was taking the deep cuts, no chatter and good quality "mans" size chips and swarf. Best wishes from the UK and look forward to the next video

[@halheavyduty]

Hey Paul! Thanks for commenting good sir. It’s amazing how far machining has come. The work you guys did in the 50s was incredible - especially considering the tooling available. Grandad used to machine everything here with ground HSS. Some of his original tools still exist… and I often just stare at them wondering what the heck he used them for!? Thanks for being part of the channel. Love having men with such a vast depth of experience like yourself in the comments.

In the 70's I was a machinist for COOPER BESSEMER in Stratford Ontario Canada. I ran 4 head mills and many Berthiez Vertical boring mills. We made ships engines, Neuclear emergency pump engines and pipeline compressors in the 40 and 50 ton range. I loved every minuite of every day till they closed the doors. I am a big fan of shop made tooling. Every piece is money in the bank. Suits our needs and as long as you are not paid $ There is a huge savings that the stores can't match, EVER. Beast works for me ! Bear Tools make the best anti vibration/chatter belts ever made. They are for automotive brake drumbs and rotors but wrap one around the Beast or piece being worked on you will be grinning from ear to ear. I have always loved BIG. Retired now and sure love visiting posts like this. BIG IS BEST EH.

Interesting that you use coolant on virtually everything just as we used to do on HSS tooling, of course heating up the workpiece changes its shape but numerous videos show no coolant being used just like with a treadle lathe.

[@bigbattenberg]

One thing I would like to discuss is cutting emulsion management. I have had some pretty shocking revelations in our shop where it turns out that emulsion is recycled indefinitely (even between machines) despite it being completely spoiled and stinking like hell. I have pulled the emulsion tank and conveyor from the big Okuma and it was shocking to say the least. It must have not been moved in at least five years, ten more likely. You would not believe it. I have literally chiseled away chunks of fossilized chips stuck in the frame of the machine. Also the tank has massive layers of black sludge which I have learned is most likely molds. The amount of solid matter in the tank (chips, sludge) meant the capacity was probably half or less of nominal. Anyway, a couple of things occurred to me diving into the subject. One: water evaporates from the emulsion at a surprisingly high rate when doing heavy machining. Two: emulsion must rise in temperature quite significantly during operation as there is only a finite amount. During a production run an equilibrium will obviously be reached. Ambient temperature is a factor as our shop is not air conditioned. Three: emulsion spoils easily and 'hobby' skimmers are a major hassle. I would like to learn about your experience with emulsion management. There is a device by a company named Hebemann called the Oil Grazer M3 which I suggest you check out. Also I have been wondering if there is a thing a emulsion refrigeration. It would make sense to actively cool the emulsion to keep it at a constant temperature during operation as well as standing idle. Not only for keeping the fluid in order but also for precision. Also I wonder if it would be a practice to drain and store the fluid during for example summer holidays as the problem seems to have exacerbated all through the shop after the two to three week recent holidays.I am thinking about refrigerated or at least some form of managed storage, also for example having a circulation system to aerate the fluid. Furthermore, I have been looking into thorough methods of cleaning the tanks, looking for ways to eradicate every last microorganism. We have a company nearby that does pyrolytic cleaning, meaning an oven doing a cycle in the 450 deg. C range which will do the job and affordable as well. Have not tried it yet but it should work great. It turns out the tank design of the big Okuma very poor, there's ribs inside all over the place making it a collection of stagnant pools. It turns out this is not a Japanese but a Dutch product, no surprises there, LOL. Anyway, the optimal route would be a new tank made from stainless designed and built to hygienic standards. Long story on a subject that seems to be not talked about a lot and is definitely not the most sexy but very critical IMO, would love to hear your thoughts.

[@halheavyduty]

It's a great topic, and I think it's one I'm going to cover (especially considering the most common question I seem to get is "WTF is the pink sauce") We switched to the pink lemonade to avoid emulsion problems / coolant going off and all the associated bacterial problems. It's made a big difference in the shop. No funky smells, and no gunked up lathes. It's good stuff. At least for the kind of work we typically do!

[@David-xo8ci]

The bacteria in the coolant are anaerobic, meaning they do well in an oxygen-poor environment. That's why it's important to have flow throughout the tank, to introduce air into the coolant. Also, skimming the top oil layer is important, it closes the coolant off from the outside air. Maybe something as simple as an aquarium pump might help introduce more oxygen? I myself have been looking into putting one of those UVC lamps in the tank, it should kill off any and all microbes. Chilling coolant is definitely a thing on larger machines. You can get ready made systems for this. On my own lathe, on a warm day, my coolant gets up to 40 degrees Celsius, which is too warm for my liking, not to mention it makes it difficult to hold tolerance. I must admit I'm also curious about the pink coolant. Anyone know what that is?

Hi Matt, I love your attitude, someone has to make the decision so you did it, well done. It all worked very well and apart from the small mishap with the reduced shank pilot drill it did the job. I have never been a fan of reduced shank drills, especially when you get to larger sizes as the torque puts a lot of load on the small shank. As far as recommedations go, being an ex SecoTools man can I suggest making contact with the local sales guy (direct with Seco Tools Australia) and get the rep to visit as they have a great specials tool department so I am sure they can offer a solution. Cheers and well done. Keep up the excellent videos of down to earth, this is how its done!. Ian

I hope the welders did some pre heating before welding, you might want to look at flux core or at least spray transfer, the welds look a little cold. Unless this part has been pre heated before the welding began I think you are leaving yourselvs open to stress cracking, assuming the part was preheated, on a part of this mass continuious welding shifts would be a the way to go. Just some thoughts from an old fabricator. Great video.

[@halheavyduty]

Cheers for the suggestions Andrew. Clearly you know your stuff good sir. Yes, the part was preheated. One of our fabricators is a specialist in ultra heavy duty welding.

[@shanerorko8076]

Re: the external coolant, drilling a hole in the centre of of solid bar can actually increase its rigidity, but it has to be at the correct ratio to external diameter. I'm a mechanic by trade, an I read an article on hollow vs solid sway bars, a hollow sway bar for a less metal is actually stiffer.

[@halheavyduty]

I didn’t know that! Bloody good to know. I’ll have to do some more research for future bars. Thanks man. Appreciate the info 👊👍

[@sabamacx]

I'd love to read this article as I'm in materials research it goes against all my intuitions and I love to be proven wrong.

[@lachlantr5589]

@@sabamacx The stiffness of a bar depends on its moment of inertia, which is influenced by both its shape and material properties. A hollow bar can actually be stiffer than a solid bar if its wall thickness is optimized. This is because the material in a hollow section is distributed farther from the center of the bar, which increases the moment of inertia.

[@sabamacx]

@@lachlantr5589 That doesn't seem right, I'm comfortable with Cauchy and elasticity tensors, can you give me or point to a worked example/calculation demonstrating a hollow bar being stiffer than equivalent hollow bar?

[@2testtest2]

I doubt this is the whole truth. If you make two swaybars of the same weight, one hollow and one solid, the hollow one is most definitely going to be stiffer. If the OD is the same, though, the hollow one is likely going to be just ever so slightly softer, but significantly lighter. The same should hold true for boringbars. The bending and torsion stiffness of a pipe section is proportional to OD^4 - ID^4. So long as the ID is significantly smaller than the OD, its negative contribution is completely negligable. Example; OD=10, ID=5. 10^4=10 000, 5^4=625. If ditching the outboard pipe would have allowed even just a few mm larger OD, I would be willing to bet, a through hole, even of larger diameter than was used, would end up being more rigid.

[@halheavyduty]

We have a large one we use for most big billets this size, but this job was an odd size. Too small one end, and too long for it to reach. Big fan of annular cutters / trepanning tools. Massive time and material saver. We’ve got a video running ours on the channel. One of the earlier ones.

Kurtis has you in the land of boring bars his is a whopping 1100 long 125mm diameter with depth of cut 900mm but is only tool post mounted . he also runs his 25mm tooling on the end . yours 1000 long and only 95mm diameter . other thing is you are running through coolant where Kurtis does not but you guys are both in the running for the Biggest Tool Award for sure . speaking of drill bits Kurtis just bought a rather large one not sure of the brand but it uses a spade type insert in the end i think . was in one of his recent videos i have a look see if i can fined it . when you showed the pilot drill thingy that this flange you just made . mat that thing is massive need to get a look see of the 3 meter one if this thing does what its is supposed to do it will be a game changer for sure . Cheers from up north

[@halheavyduty]

Cheers mate! I was limited by hole size 🤣 Although after seeing how The Beast performed, I’d challenge any half meter bar to a race for metal removal. Bloody thing just EATS IT UP. While I’m def not competing with bar size… I think we might have the big bar best pretty soon. Gotta build a 1m+ 120-130mm bar to machine the next project. 1.2m one tonne crossover sub… and even the beast can’t reach that far. It never ends bro 🤣

[@flikflak24]

i saw that you finally put the beast to use. and it has its its cooling line soldered/braced on the side/down in a slot and that kong also have gotten a mounted a curved tube thats also pointed to the insert. dont know why but i kinda feel like im responseble/sparked the idea for that for some reason xD it all looks and sounds good m8 also when i do my final pass with a boring bar i always turn the insert to a new/barely used edge/corner and after that pass turn it back to the more used edge/corner btw is that new drill only gonna do through hole boring or do it also need to do blind hole ? if its only through hole then trepanning without any hesitation. but of its also have to do blind hole then a insert drill /spade drill ( just like the kraken is ) maybe even with a shop made insert center tool

[@halheavyduty]

You (and a handful of others) definitely were the creative inspiration for Kong’s final form. An excellent suggestion that I’m really grateful for! He runs SO much better with through coolant.

@@halheavyduty i do have a idea to how you can make/rough out the holes pretty effective and stable though it will take some work to make/get it up and running the first time ( its basicly to put a spindle on the cross slide with a facemill on a long extention. run the spindle on the lathe at like 3-5 rpms with a feed of about 2mm pr rotation. so your doing a ramp/helical movement/interpulation of the whole to about 2-3mm smaller then fonal dia. and then take the beast to final size ( masicly so long that the hole is at least 1.5X the facemill then no problem

For the drill you could also use a Fanuc G74 cycle. A G74 cycle is normaly used as a face groof cycle. Good reason using this cycle is the drill Will peck and Wont retrack all the way out of the hole. I could send you a example of you like.

[@lachlantr5589]

I’m a CNC machinist in the drilling industry same as you but in WA. I’m curious as to why you use such large depths of cuts as it significantly reduces tool life. We never produce more than 50 of 1 part at a time, so tool life is more important to me than metal removal rates. If I’m running a super expensive part on a super expensive machine with super expensive tools and an insert breaks. There’s no way the time saved by running high depths of cuts would be able to compensate for the cost of the damage.

[@halheavyduty]

That’s a really good question. I tend to run the machines / inserts at what I consider a “comfortable maximum” So on the big tool joints we’re building, Im running: WNMG @ 3.5 DOC CNMG @ 3.5 DOC Well under the insert max rating. Spindle load sits at around 40% Z axis about 30-40 % With the big 16mm CNMG tips, in my experience they can handle very heavy cuts. 4-5mm without a drama. I think I’ve just done about 2 weeks on a single insert. Remarkably durable, and even when the break, they still cut. Worst case scenario is we lose a KM80 head on the big bar - which is about $500. And I’m ok with that if it happens. We have a very tight deadline on this project and there’s a huge amount depending on these components being made on time. Hence why I run things hard, but not crazy (in my opinion). With little subs I stick to 2.5 DOC because we have no real time deadline. Really appreciate the insightful question. I find it’s sometimes hard to find the balance with regard to how hard to push things.

[@MegaRich7]

Just need to be carefully when you are peck drilling and using external coolant. This will allow chips to be washed back into the hole and get wedged between the drill and workplace. This will chip your drill insert and cause premature tool failure.

[@halheavyduty]

Thanks for the tip mate! Much appreciated. The external coolant was just to try and wash the swarf off that bloody nose. Clearly worked well 🤣 fark

[@jameswood9764]

Use spade bits example ALLIED MACHINE AND ENGINEERING make your own bar to fit??

We used to run spade bits, but found they eat up too much Z axis load on the CNC. We still run them occasionally in the hulk, but need carbide for the CNC. Next machine I buy is going to have serious Z axis power.

what's the pink coolant smell like?

[@halheavyduty]

It doesn’t seem to have much smell. Which is great. A lot of coolants smell horrible after a while. They can get a bacteria in the mix and it’s a real problem. This stuff doesn’t go off - which is a big win for the shop

[@1ginner1]

Jesus dude, that drilling cycle (at 10:00) with the peck is really nasty. I would have expected a maybe 1mm Z clearance after each peck, but it seems to be going straight to depth with no infeed to restart the cut, if you get a chip between the tip and the existing cut the tip will loose. I understand the need to get the drill as rigid as possible as soon as possible, but man that is nasty. lol

[@halheavyduty]

Dude it was a nightmare to run. Lots of troubleshooting going on right now for future jobs. I’m still astounded that it didn’t even break an insert on the final 75mm. I fully expected it to exit needing serious dentistry.

[@dwjr5129]

So the Kraken farted and failed but the Beast… As my dad used to say, it carried the mail! What was the size and series of flange you welded to it?

[@halheavyduty]

The flange measured about 450mm from memory. The billet was 320mm

[@nialltm1991]

Kinda sounds like the drill is rapid feeding to the bottom of the hole, and then feeding rather than feeding in each peck @13:01.

[@halheavyduty]

Yeah… it was a bit of a shitshow. The chatter caused issues. Mostly because the HSS nose drill took up over half the Z axis power so I couldn’t drive it hard enough. Def a learning experience 🤣
