Once again another excellent video from you Dave, Do like the explanations of the procedures that are involved with large bores in one cut, you make it look so easy.
@@userwl2850 Trial and error is the best way. I learnt my lesson trying to drill stainless sheet metal. Killed all the Hss. 3/16 drills I had. It kept heat treating it trying to drill through it over and over again. Lessons you dont forget when you find solution. Love your set up with the tube holder and the massive hunk of rod. Steady rest has some mods too. Save the core for other projects. instead of making 300lbs of chips for the recycler. Hats off.
Big just seems to be getting bigger Dave - phew! Always beats me how you manage a perfect alignment when you change ends (gravity and all that)! That 6' long one with large bore has to have been among the biggest buggers - but then the 88" x 10" bore - damn. As usual, impressive chips. Suds look well generous. Usually find it hard to imagine where the finished work ends up when such large stuff. Go get your John Smiths!
Hey Chris.. they always meet up. Only thing that happens is like I said .. The bore gets smaller... not by much.. that's why it's best to meet up halfway. Going for a pint now 🍺🍻
So many questions. How do you support the billet to cut the track for the steady and centre drill it? What's the ball park value of pieces of metal like that? (Typical) Do the customers want the cores returned? I've only just found your channel so sorry if you've covered this. What type of industries are your customers? Great interesting videos.
with the amount of coolant used on a machine like this, is it recirculated and if so, is there much waste besides waste metal? Amazing work and addictive to listen to. Thank you for reminding me of home. Yorkshire forever!... stuck in Wales...
i was once told that it was true enough that DSG were the rolls royce of lathes but lang was the daimler, , i was also told that DSG used lang lathes as well as their own!. my little lang juniour is as fine a small lathe as i have ever used 60 years old. nice work as always, nice to see a big lang still doing the business
Hey thanks for sending me over here to see this combo trepan / boring job. Quite impressive hogging going on there! More questions for you: What was the smallest ID trepan machining you ever have done? And how deep? Have you ever cut a trepan face over and past an existing shaft diameter?
@@userwl2850 Thanks David for your kind response. I truly admire your machining accomplishments. One of my "accomplishments" working in a "job shop" that I still remember (and still have a NFG sample), I once had to cut many trepan faces on multiple parts around and over an existing 3/4" dia. that stuck out 2 1/2" inches in front of the intended trepan face of this lathe part. The trepan inside dia was to be from the shaft's existing 3/4 dia, cut to an outside dia. of 1/3/8", approx 9/16" deep.....into H13 material! The bottom insides of the trepan had to finish with 1/16" radii both inside and outside. I had to hand create/machine a tool holder, which held two custom created and custom ground "standard" carbide inserts... top and bottom. A round plunging/pecking tool with clearance for the existing shaft. The problem of course was the tightness of the radial clearance and fragility of the tool to accomplish this clearance. Coolant flooding of the tool and chip removal (pecking) was essential for success (Also many "backup" carbide inserts). The shaft dia. plus major OD and multiple face(s) of this machined part were all later (after heat treat) OD ground together square and parallel with each other within tenths, so that all surfaces fit into a precision injection mold of some kind without leakage or "flashing". BTW The insides of these parts were also a "bitch", as they had a relatively deep (1/14" ) and small (1/2") internal fine thread and "seat" inside the shaft, that had to bottom precisely for some kind of replaceable nozzle insert?
What kind of lathe is that one? And what size is it? Is there a greater risk of the core jamming something up close to breakthrough? That metal was tame compared to some of the exotic stuff you have done before. Good job!
So if the inserts are always pushing the trepanning tool in the same direction away so that the bore gets smaller and the core bigger, why arent the inserts set up in that way, that both forces cancel each other out, like for example if the entering angle of one insert is slightly different than the others?
I'm using Google Translate, if the translation isn't perfect, I apologize....... One question when the tool is getting close to the end, doesn't it tend to go down due to the weight? If there is any secret in assembling it, please could you explain it to me?
I see you're in a different workshop to your one, do you rent the machines or something? Or is that your day job and your other workshop is weekends? Thanks for the videos, keep them coming. My mrs thinks I'm mad for watching these but I find them really interesting!
how long did that big bugger take to do? Can you start it off in the morning, go home, come back at lunch time to turn it round and then come back again at knock off time to unload lathe? 😉
Impressive ... this has “high risk - high reward” written all over it. Kudos, man! Great job!
Thanks buddy 👍

Thanks Chris. Maybe I should film the bad things that happens 🤔
@@userwl2850 Yes a few of the hiccups but most importantly how you put a balls up right would be most interesting to see how you fix it .
I also like working alone when I set stuff up. everything is done how I like it, and it just works.
I bet they are loving you in that shop
Working alone eliminates someone else's failure. 😉

Largest job you've ever bored, yet you've still got it chucked in a sub chuck lol.
The gap is not in line so need the Chuck in Chuck for short jobs 👍

Great interesting videos.
Each video getting more amazing
Thank you 🍺
Wow! I just realized that you are cutting a core from that ! Talk about conservation of materials.
What is the final product used for?
This method is good, I like it, but not many people use it.
May I ask what inserts work in the front?
Amazing....my goal is to meet you one day and take a tour of "your shop"....and of course meet Stella as well :-)
Wow... thanks Richard. What a compliment. How are you these days. No videos for a while now.
with the amount of coolant used on a machine like this, is it recirculated and if so, is there much waste besides waste metal? Amazing work and addictive to listen to. Thank you for reminding me of home. Yorkshire forever!... stuck in Wales...
Loose coolant through steam as it gets hot. Thanks for your nice comment. 👍
You latest lathe runs exceptionally smooth
Too quiet. Hard to tell when things start to go wrong.
Great video Dave... who is this firm? Hydraulic ram cylinders maybe ??
Amazing work 👌
Thank you
Nice job. So you put coolant throug the center of the tool so you can see on the coolant stream if the core is jammi ?
Exactly.... 100% correct 👏🏻👏🏻
Nice Lang lathe , still going strong !.
Yes it's a Lang. 👏🏻
i was once told that it was true enough that DSG were the rolls royce of lathes but lang was the daimler, , i was also told that DSG used lang lathes as well as their own!. my little lang juniour is as fine a small lathe as i have ever used 60 years old. nice work as always, nice to see a big lang still doing the business
The Lang lathes are brilliant... very strong but not as good as DSG lathe. 👍
Великолепная работа 👍
Hii dave awsome work can you tell me description of the machine
good job. How do you compensate for bed wear on these big old lathes when dialing in the stock (which sags) to the tailstock quill?
Over time you get to know each machine has their own quirks.
Hey thanks for sending me over here to see this combo trepan / boring job. Quite impressive hogging going on there!
More questions for you: What was the smallest ID trepan machining you ever have done? And how deep?

I'm currently making a Trepanning tool to cut 75mm. Stay tuned. 🤞

The symphony sounds of the cutting
Hello Mr. Wilks. Just checking in and making sure everything is okay.👍
Very good.. could you tell US now to turn offset bores.. bearing housings at the same centerline
I'll make a video next time I do it... 👍
would have liked to see inside the bore to see where the 2 bores meet in the center.
They always meet up true but as I said the hole can get smaller. Best to meet halfway.
Your nickname “Lone wolf 🐺” what is the flow rate of the flood coolant ? 👍👍🏴
I honestly don't know.. 🤔
What kind of lathe is that one? And what size is it? Is there a greater risk of the core jamming something up close to breakthrough? That metal was tame compared to some of the exotic stuff you have done before. Good job!
I think it is a John Lang & Sons lathe. Looks like one shown on Tony Griffiths website.
@@hmw-ms3tx thanks, it is an impressive machine.
It's a Lang lathe. The core gets tighter exactly at the halfway point.
Lovely job David, any idea what they are used for.?
Gas pipes I think. 🤔
Отличное видео! Хотя язык не понимаю, но инструмент у вас отличный! Спасибо за работу!
how did you managed Speed, Feed Setting ??
So if the inserts are always pushing the trepanning tool in the same direction away so that the bore gets smaller and the core bigger, why arent the inserts set up in that way, that both forces cancel each other out, like for example if the entering angle of one insert is slightly different than the others?
I like your thinking.. very intelligent. They are set so the forces do that.. works easy on short stuff but obviously there are limits. 👏🏻👏🏻
Quero ver o começo da usinagem
Only the impossible challenges give satisfaction
I've never heard that before and.... I love it. What a great thing to say. 😎
Yeah !
If it’s possible, I’ll do it strait away. If it’s impossible, it’ll take a little longer!
I'm using Google Translate, if the translation isn't perfect, I apologize....... One question when the tool is getting close to the end, doesn't it tend to go down due to the weight? If there is any secret in assembling it, please could you explain it to me?
Que bruto meter la mano cuando la máquina está en funcionamiento
that'some serious time in cut . Ever busted up a big tool along with the part ?
YES. Lost a few tools over the years.
Does gravity not make the tool dip as it gets well through tapering the bore?
The tools are made from 16mm wall pipe. They're really not heavy. 👍
The rotating workpiece keeps it mostly straight anyhow. If the drill was turning and the workpiece stationary you’d have a lot more of a problem.
Nice video.amazing size of work. HOWEVER, don't lose an arm to show us chips!!
It's safe when the metal is chipping 🤞
5:50 what's that spiral pattern on the core?
When I get to depth bore by trepanning the first half the tool is brought out with the job still spinning. Less chance of tip breaking.
That coolant pump is really pumping
Awesome
Thank you.
watching this just ticks me off. all those times I wore my arms out drilling, then wore out my shoes taking pass after pass with a boring bar......
Oh dear.... this is much easier 😩
Is that the circle tos machine?
We have an 84" boring head, that'll go out to about 120.
Nice video sir
Thank you.
Nice, any idea what these are for?
Gas pipes I think.

How are you getting the coolant up to the cutting head ?
Look at my "Trepanning why through coolant is important" video.
And not a cnc in sight.
show the tailstock side of the lathe machine, let's see the tool tool section.okeyy
Hi. I have many videos that show that if you look on my channel 👍

Oh.... if only that were possible..... actually it's a damn good idea.... need to look for a longer bar 😉👏🏻
userwl2850 I have lots of good ideas, if only some of them were practical.........
@@chrisstephens6673 well you are halfway there with the ideas, now to find the solution.
@@markfryer9880 there's the rub, anyone can have an idea but.......
Oh yeah…did that on a Webster and Bennett vertical lathe!
The rope tied over the steadyrest is interesting.
Holds the Splash tray. Had me buggered for a while too.
what are thay used for
Trepanning Master Yoda on a Friday night
Master Yoda 🤣
Might as well go ahead and find a 10ft thru 10" slug to do. :-)
😂🤣 it's coming soon. 👍
great job,my job
Are you in effect coring the hole as thè cuttings do not appear to be the full or half diameter of the hole
Yes exactly that 👏🏻👍
Your never to old to learn new shit. Stick in there David.
What was your beer of choice after that?!
GUINNESS 😉🍺
9:29 could make a giant fire piston
Or a giant gun barrel 💣💥
whats the part for ?
Gas pipes 👍
What’s the spindley rope for?
Holds up the coolant guard/splash pan.
It holds Th e coolant guard.
whats the piece for ?
Gas pipes 👍
How long does something like that take?
Approximately 6 hours each 👍
Get much of a step where the cuts meet?
Not much if they are done exactly half and half.
Wow nothing else to say, 😁
