Sorry things didn't quite so well for you this week. It happens.. I was working at a shop and early in the morning we had everything running. The guys were working listening to the tunes. So I was standing at the entrance with my coffee taking it all in. Then the owner came up behind me and asked what I was doing. I said look at that, everything is going well. Take a good look because it ain't gonna last... He busted up laughing and walked away. Machining and manufacturing is tough...some weeks are just better than others.... Keep rocking it!

[@halheavyduty]

So true 🤣🤣✌️ It’s the nature of the game. The thing I enjoy about machining the most, is the constant challenge to solve problems. I absolutely love coming to work, and wake up (most days) excited to fire up the machines and start spitting chips. There’s good days. And not so good ones. All in all, I wouldn’t swap careers with anyone right now. And I’m fortunate we’ve got a great team too. Makes all the difference working alongside men who want to work.

Thank you 🙏 Should be fun to trial out the beast. It’s a bloody sturdy looking bar. Just unwrapped it and it’s spot on. The whole team worked on this one and did a bloody fantastic job

[@starbolin]

A ground straight tool shank in a ground rigid holder will stick like that. Any tool taper less than 8 degrees will stick. To prevent welding, the shank angle should be more than 12 degrees. Think collet or cat taper. Alternately, use a split clamp.

[@halheavyduty]

Yep. You’re right there. We’ve created some more clearance to see how it goes. The Hydra is running right now - no issues yet thank God. If we have any more problems in the future, it’ll be a split clamp setup for sure.

[@jdvid007]

You could slit that holder down it's entire length and weld on some lugs for pinch bolts. I think this would reduce vibration and increase holding power significantly. You can slit your bushings also.

[@halheavyduty]

We did pretty well on all the tests, except the Kraken drill. It’s shop made so I’m getting a proper one. Will see how it runs. Might end up doing your suggestion if it vibrates. Thanks mate

[@shanerorko8076]

That tool holder, you could've made it so it has a bolt down cap, use 10 9/16" ARP main studs from a engine, it should have like 100t of clamping force. Just make spacer blocks to hone it then take the blocks out to clamp it, but the cap would need to basically be a block of steel machined to fit the tool holder.

[@shanerorko8076]

You could also use nut serts on the base so you spread the load into the base better. Drill down like 100mm from the cylinder so the pressure doesn't distort it.

[@halheavyduty]

If I make another one, it’ll be the bolt down two part style. I’m hoping this will work just fine. Hoping…. We’ll find out next week for sure 👍

[@halheavyduty]

Cheers mate. I love CEE videos. Still got swarf bin envy 🤣🤣🤣

[@bigbattenberg]

Here's some tips. Getting tools like this to slide in and out perfectly can be done but due to the weight etc. cocking and then getting stuck is a major issue. So, sticking to this design some kind of pilot would be needed as a guide (e.g. a smaller bar sliding into the bigger bar with a centering bushing on the end). Another solution I have seen used is a slit holder where the cap can be removed completely. This makes for an extremely stable clamping, the only thing is you need to index your insert to the machine CL. Just lift you boring bars in and out with no risk of cocking, ever. Actually we have a custom made holder sitting in the shop (yes we cast our own castings) which was done this way and it holds a mega Sandvik bar (probably a silent bar) of which I am afraid to ask the price, LOL. It was used on one job and now it is collecting dus. in fact the whole thing bolts directly to the cross slide so it could not be more sturdy than this. I forgot to measure the bar dimensions, will let you know.

[@halheavyduty]

Awesome. Thanks man. Yeah if you find the bar dimensions (or any info about it let me know) Super curious.

Roll on next week 😀😀Looking forward to the beast unveiling. Did a quick back of the envelope calculation: 3m drill going down 250m will remove about 5,000 tonnes of material! 😲😲

[@halheavyduty]

It’s wild hey. The major advantage of drilling from surface down (as opposed to traditional raise boring) is that the material just comes to the top… And doesn’t have to be carted from the bottom up. It’s why the whole mining industry is so behind the success of this project. It’s a massive time and safety improvement on all levels.

[@EastBayFlipper]

That 3-meter drill would be delightful for targeting ore bodies for extraction but it would be game-changing for geothermal energy development. Quite the size for a boiler😮 Again, please keep managing to find time to produce these videos because vids like these show what trades do and it surely isn't being a robot's stand-in. With my papers, the last job I was offered would have started at $100.00/hr and 2 months paid vacation. Trades are in demand everywhere 😃👍🍻

[@halheavyduty]

Hey mate, yeah I think as the tech gets proven and gets more exposure… there will be a lot of possibilities for a rig that can do these type of holes. Especially when it’s drilled on air, and from the surface (as compared to mud drilling & the raise bore option) New video lands this Friday. It’s been a wild week in the shop 🤣

[@terrafarms7370]

HI, FYI a good mate of mine who passed away used to work in the mines as driller on air shafts, elevators or any other use's that the mine's needed. Most of his work was around 3 M & on some jobs they would drill down 250 to 300 M & then drill back up at 6 M. I'm pretty sure he said 6 M, as too open up a huge cut for machinery to go down on a gold mine, all in Australia. Pretty Cool with what you can run with these Hyd powered drilling rigs.

[@halheavyduty]

Yep. They dig some bloody big holes for the mine shafts. The real difference with the big rig we are developing is that it drills top down using air (as compared to mud) It’s a bit safety improvement as you don’t have 5000 odd tonnes of mud sitting above an underground mine. It’s a lot faster than the big raise bore methods too. Those big rigs that do raise bores are insane. The bits are enormous!

It seems to me that an eccentric rotating cylinder to lock the bar in place in the tool holder base might be a good design to consider. This would be a 6” to 10” long captured rotating tube between two stationary base tubes. With a corresponding central eccentric outer diameter of 0.003” for the central tube ID to lock on to the tool. It will resemble a breach lock on a cannon. Just an idea I had.

What a shame it siezed in the hole. I have seen it with stainless to stainless. Once its starts its all over.

If you didn't get everything correct the first time it was back to the lathe to machine it off and start all over again. I think the call it the school of hard knocks buts its still a bastard. Cheers Ian

[@grahamkeegan2706]

tooling is starting to get real. Just curious if you possess a large horizontal borer in your shop - i cant help thinking that might not be a bad investment. (by large i mean proper large, not what most people think of) I used to work on a rather large Craven lathe that had a 12 foot faceplate and was 15 meters between centers - we used to turn rudder shafts and prop shafts for naval vessels - sometimes they were actually bent fomponents and we could have upwards of 8 tons as counterweights on the faceplate. those days of heavy machining seem to be a distant memory now. Aprentices seem to have a hard time understanding that we used to put on a 25mm depth of cut at a feedrate of 1.6mm/rev and could fill the hoppers in a few minutes.

[@halheavyduty]

We don't have one yet, but I tend to agree with you. We might just be looking at a proper sized one in the near future.

Easy mistake to make. We don’t take tools to the max. Usually 60-80% of manufacturer suggestions. Thanks for commenting brother 👊

[@thecoxicle]

I might have missed some one else say it but why not weld a KM80 to KM80 extension to the end of a bar, that way if you destroy a tool you've got one bolt to undo and you can also change to any other KM80 tools.

[@halheavyduty]

It’s a really good question. To be honest, it was just an issue of cost. I couldn’t justify laying out over a grand for the setup. We already had the head welded to our old “Godzilla” bar and a big bit of steel sitting in the yard I could build the beast from. I don’t really need to change the heads over, I just wanted to use the KM80 CNMG head after seeing how well the KM63 head works on our equally ghetto shop made bar “KONG” works. I don’t imagine we’ll have issues with the head itself, hence the decision to just weld it on.

[@thecoxicle]

​​@@halheavyduty eeeesh where I work bought a WFL mill turn with a KM80 spindle so I've ordered the necessary tooling for it, as they love to use a single supplier and they have a Kenna contract I've never looked at price just tried to box clever and keep holders to a minimum. Used alot of the CNMM 250924 inserts and I suppose even when they chip they still cut and the tool is fine. The Kenna rep did convince me to try a Fix8 tool and although it really chews metal out when the tip went it went and the tool very quickly weld to the OD of the part. Great channel by the way I love to see others who love the trade and your content and editing make it a pleasure to watch.

Yeah its amazing how robust those CNMG & CNMM inserts are hey. It's definitely my go to for heavy roughing. I was looking into the fix8 tools just last week. Do you recommend them, or do you have another preference?? Thanks for the channel feedback. It always means a lot when coming from other machinists with clear experience in the field. Appreciate it brother!

[@thecoxicle]

@@halheavyduty FIX8 is overly complicated with it silly clamping arm through the centre of the insert, locks you into Kenna tips and apart from more edges I see no benefit over the CNMG which gives you more process reliability. What really put me off was when the maintenance guy found a KENFIX (I think it was called) tool in a back room and gave it to me that was just a FIX8 they release decades ago that showed me it didn't catch on back then either.

[@halheavyduty]

Good to know. That’s kinda what I thought and have stuck with CNMG. I detest being stuck with non iso tooling. The inserts (in Australia) cost over $40 each for the fix 8 so I just couldn’t justify it. We can take 4mm cuts with an $8 WNMG or 6-8mm cuts with a CNMG all day long anyway. I like a lot of Kennametal tooling - especially the Udrills, but always look for ISO inserts where possible.

It’s definitely one way of doing it - but we wanted the holder to be universal for a bunch of tools that have variable lengths. Like the drill. Sometimes we drill at 250mm, and others at 450. Needs to be a straight shank for it to slide adjustable. I could have made it a bolted clamping system, but chose to give this a go first. Has worked pretty well so far.

​@@steve_weinrich my guess is the holder was hot and it heat shrunk around the boring bar

[@halheavyduty]

I would have thought so too. Our apprentice was finishing honing / cleaning up the bore, and it was a very tight fit. We were aiming for a 0.02-0.04 clearance, but he test fitted it early. There may have been a little bit of material that wasn't properly cleaned off either the bore or the bar (I dont know for sure)... but it slid in (just) and then locked up. It does happen, and then the slightest friction heat at such close tolerances just led to it lockin in. And I mean LOCKED IN. I was genuinely surprised how tight it got stuck - considering the bloody thing went in by hand fairly nicely. Metals & expansion. Gotta love it. The odd bit of shit that likely got caught in there too (my guess) probably doesnt help. You live and learn... Twas definitley a week of character building and 'learning experiences'...

Thanks mate! Appreciate it. We’ve made the fit a little less snug, so hopefully we don’t have a repeat of the Godzilla fiasco

5:32 Guys, that thing is NOT a hone. It's a glaze breaker. You can't expect a round hole with that.

[@halheavyduty]

This is true, but it worked. Around here we just have to make do with the tools we’ve got on hand (a lot of the time) We’re about to find out if it did the job well enough… so wish me luck brother.

[@adrianklaver113]

Looks like a cylinder hone to me.

[@billshiff2060]

@@adrianklaver113 Naw , lots of people mistakenly call it a "hone" but it is only a glaze breaker designed just to scuff up whatever surface is there. An out of round cylinder will stay out of round with that. Likewise a tapered cylinder will stay tapered. These spring loaded things as well as those "ball hone/flex hone" things ONLY make a surface on whatever they are in. Crooked or not. An actual hone will straighten out and round out cylinders as well as surface it while finishing it to a precise size. Look up Sunnen hone to see the differences.

[@billshiff2060]

@@halheavyduty Well good luck to you brother.

[@halheavyduty]

Cheers mate. Fortunately it all worked out. The hole was round to begin with (it was bored out in the lathe with a fairly rigid setup). Appreciate the comment.

[@markneedham752]

Just a tube smatarse😊 but maybe a taper Morse or jit ??. instead of parallel.😊😊😊

[@halheavyduty]

Not smartass at all. We chose to go parallel se we can adjust the length on the Kraken & Hydra. The Beast is built to be a standard 4D tool. I’ve found most of our bars perform well up to 4.5D so fingers crossed it’s as rigid as hell.

I also have a question about your cnc lathe with the Tailstock is it a Manuel tailstock with a Handwheel it it just fitted with a live center or is it also possible to use normal drills in there since you use only the quick change tool post to drill

[@halheavyduty]

Great question. It’s a manual tailstock. Has a geared 1-1 and 1-2 handwheel. Bloody heavy to move around. If we get a bigger lathe I’ll be getting a fully programmable one so we can do large center drilling.

[@beriklelmut1842]

@@halheavyduty that’s cool that lathes come with tailstocks that have 2 gearings probably for bigger drills so you need less force on the handwheel I would Imagen on our rougher lathe it’s a tum 35 famot come from Poland the tailstock is bloody big for the machine since we also cal the tailstock on that machine an anvil

[@halheavyduty]

Hahah. Anvil sounds about right. Yeah, the 2 speed gearing is excellent. Makes a big difference.

@@halheavydutyyea using a 29mm has drill even pre drilling it takes so much force

[@halheavyduty]

My grandad used to wind in a 50mm HSS drill when making crossover subs. It took forever… but that was back before Udrills & carbide drills. I used to watch the swarf peel off as a little kid.

[@lytken]

why did you not use weld on the bar instead of the nickel rod

[@halheavyduty]

They were all tied up building the MEGADRILL. I also wanted to avoid any distortion that gets caused by welding.

We probably bought Godzillas head off you guys 🤣

[@martindennehy3030]

Not the best way to hold it. A round in round will always spin on you. Flat or square held is best, it cant spin. If you're going with the round, the half round bolt down clamps with size for size bar and hole fit would work best.

[@halheavyduty]

You're correct. We wanted the toolholder to double as a holder for our drills, hence the decision to stick with round and just use locking grub screws on the side. Hasn't budged yet fortunately, and we've done some pretty heavy cuts with hard feed since setting it up. Thank God.

[@1992jamo]

This is so far from my home workshop experience that I cannot believe how big this tooling is. Just out of interest, why was nickel brazed onto the parts for a repair, over something like MIG? Thanks for the vid.

[@halheavyduty]

It’s easy to machine, very durable and doesn’t distort like weld. Excellent question.

[@1992jamo]

@@halheavyduty Ah right, makes sense. Thanks so much for a reply, I've subbed!

Most welcome my friend. Thanks for tuning in and jumping on board.

*_Nickle coat? Better than bronze? I never heard of it but then again I don't do very much welding and oxy stuff. I have to say, you have a Hollywood movie going on in your shop. I'm just waiting for the stay puff marshmallow man from ghost busters...._* 🤣😆👣👣👣👣👣👣👣👣👣👣👣👣👣👣👣👣

[@halheavyduty]

🤣🤣🤣 It’s a wild show for sure some days. Thanks for tuning in mate. Yeah, the nickel cost is what we use to repair drill bits. Very durable and pretty easy to use. We use it instead of silver solder when it’s a reeeeally damaged bit.

[@Failure_Is_An_Option]

This is why we can't have nice things...

[@halheavyduty]

I know right... fark

[@MichaelLutz]

I'd make a split ∅ 4" cross slide holder and split sleeves to use it with smaller boring bars. It can hold a 4" boring bar which is probably as much as your machine can handle. We have several of these boring bars with a Capto C6 adapter at the end for quick tool changes. You can also easily extend the boring bar if needed. The one in the video below is a short version with a regular 2½" tool holder. kzbin.info/www/bejne/opDRY6GYer-hY5Ysi=bE1Qig1QiZuZb17G

[@halheavyduty]

Yeah, not keen to go above 4”. To quote JAWS… I need a bigger boat 😜 Thanks for the tip. I’ll check that out. Sounds like you’re doing some great work yourself mate
