🤣💯

Thanks very much for the kind feedback mate. Much appreciated.

Totally agree!

Not an option in this case. We have a large trepanning tool, but it wouldn’t quite reach. The holes on either ends are also different sizes with a taper in the middle - and the smaller was 50mm under the size of our trepanning tool. For about 80% of the jobs we get, we can core it out no worries… This setup is for the other 20% 👍 Excellent question by the way.

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 🤣

It’s a tool joint for giant drill rods. They’re an RC rod, so each one also has an inner tube as well - hence the gigantic size. They’ll be used to drive a 3.0m drill bit that weighs about 18 tonnes, 250m deep for underground ventilation shafts

The Beast def lives up to its name 🤣💯👊

Thanks for the great feedback brother. Karen & Kurtis have really nailed it with the quality of their work. Love their videos. Working to improve ours each video. Long way to go, but enjoying the process. Lots to learn! Lucky this job provides endless content to experiment on 🤣 Def no shortage of material for future videos 👊💯

What speed / feed would you typically suggest? 100% open to suggestions from someone who’s run these drills before. It’s a 50mm HTS drill. Thanks for the comment. Appreciate it 👊

Excellent suggestion. We did that soon after the video and it doesn’t vibrate at all now. Really grateful for all the helpful comments we receive on the videos. Cheers my friend 👊👍

It’s a mega time saver in the shop. Well worth investing in.

The beast has one hell of an appetite for steel 🤣

@@halheavyduty lol, so I noticed, got to be close on 20mm per pass off the inside diameter. As the name suggests "what a beast" 😊

It’s a Quantum bed type milling machine. FBV-S5 is the model

Cheers brother!

The first three times I tried running it it conked out. Went with a wimper. Just cut out. Had to halve the feeds and speeds to get it to run properly for the lathe we’ve got.

Im pretty happy with how it performed. Very rigid considering how long it is.

Thanks mate! And well done to you on all your fine content. Great to watch 👊

Cheers Peter. We are based in Rockhampton (Qld)

Yep. It’s like a bad version of Cloverfield. You’re def not the only one who pointed it out. Worked really hard to make sure future videos are much more stable. I think we’ve got it nailed now, but let me know if you watch the latest one. Apologies for the vertigo my friend 🤣

Dont they just! Noisy… but for us… essential. I’ve found running them slower than manufacturers guidelines tends to reduce noise. At least on 4140 steel. What material do you machine mostly?

🤣👊

Cheers mate 👊👍

The welds crack upon cooling. Especially with alloy metals.

@@halheavyduty thank you for ypur information sir

Not a problem at all.

Sure bro. Will add it into a Q&A vid that’s coming soon

@@halheavyduty Thanks mate. Did you guys build them or ?

Yes. We built them and got them certified by external engineers.

Yes. We built them and got them certified by external engineers.

Yeah, agreed 100% It’s just a bar for doing odd jobs and the old Kenna LH ext tool older just happened to be sitting in a drawer. We built a specific CNMG bar for hogging. It’ll be up in a video this week. Thanks for the input mate! Glad someone picked that up 👊✌️

Just finished the video, great work! Super Excited to see the next video. Not sure if you saw my comments on previous videos, but we should put together some sort of discord server or similar for sharing info on this type of work. Particularly the core drilling/ trepanning tool design work I would love to pool our knowledge on.

I saw that. Def looking into it right now. It’s a great idea that I think we’d all benefit from greatly! Thank you 👊

Hogged it out beautifully. Didn’t even vibrate!

@@halheavyduty all the base settings were on point. Almost musical .sweet success .a simple task yet so many variables to achieve this .keeps em coming !

Cheers mate! It’s very fun to play with 👊

Nice one mate! Yup. When all goes to shit… someone’s gotta come in and sort it out.

I could make a fortune with the number of slinky’s we’re producing right now 👊🤣

Cheers brother! Yeah we use the top notch on all the lathes. I really like it. I’m told there’s better out there, but considering I’ve got about 20 top notch tool holders… we won’t be changing any time soon 🤣 They’re very robust inserts I must admit. Gets the job done just fine in my opinion.

👊💯

Thank you good sir. Was a good challenge! If you check out some of the other videos, I usually have a steady shield. Nothing worse than swarf hitting the bearings at high speed! I left it off for this job as we were well inside the bore before machining started. Thanks for commenting mate. Much appreciated. And please keep any tips coming - especially if you see me do things you think could be improved. Zero ego on the job. Always keen to learn 💯

Thanks for the reply, I do intend to watch all your excellent videos, you know you never stop learning on the job till the day you retire. Best wishes to you all down under.

Thank you my friend. Sending very warm wishes from other side of the pond 🙏

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. Fingers crossed nothing gets stuck in the future! 🤣

It’s a profession I thoroughly enjoy. Never a dull day in the shop with all the crazy stuff that keeps pouring in. Beats sitting in an office (which I previously did more than id care to admit 🤣)

It actually does 🤣💯👊

✌️

🤣

The bar didn’t budge at all. Thrilled with how well the big boy performed.

💯🤣👊

We ran “the hydra” which was an 85mm bar and it did deflect on heavy cuts. The shank is 80mm The beast however didn’t budge a bit. It was 95mm with the same 80mm shank. I think most rigidity comes from the bar diameter as long as it’s clamped properly and butted up hard to a face. Ideally the bar wouldn’t have a reduced shank, but there was no option here - and I didn’t want to create another tool holder for the big bar.

@halheavyduty understandable sometimes we have to make do. Thanks for your reply Matt keep up the great work I look forward to it each week.

Cheers mate! And thanks for the kind feedback. Much appreciated. Really enjoying making the vids each week. Crazy jobs keep coming in the door, so content just kind of creates itself weekly 🤣

It didn’t break an insert. The CNMG inserts it used are extremely durable.

🤣✌️

Any suggestions??

It’s bloody satisfying to run. Just a straight up metal monster

It had a deep taper, so I stuck to 5mm cuts. I reckon it could do 7mm cuts though. Will test it out at some stage soon

Me too bro 🤣🤣🤣

Good to know. Thanks mate Releasing the full video of building the beast. It has no music

Yes, way too freaking loud... Think of those poor people watching youtube with headphones on.

lil bit for my liking yes. machining itself is music to my ears!

I’ll be mindful of that in the future. Appreciate the heads up. I’m going to buy a good set of headphones and pre test videos.

@@halheavyduty this is the way. Viewers' ears will thank you. Keep the good contents coming !

Not doing 5mm cuts. Didn’t budge at all

@@halheavyduty how deep have you taken I work in imperial .196 is a decent cut with no deflection!!

Currently 0.196 is the deepest. The next chance I get I’ll test it up to 0.275

@@halheavyduty can’t wait to see it!

Me too 🤣👊
