Well Drilling, Coupling MOD

The sealing surfaces on a water port coupling have worn out and we machine the modification into the coupling to support two wear ring sleeves. A good example of machining hardened steel alloy with interrupted cut right in the center, along with work hardened areas around the worn out old surfaces. ;{)------

[@newlifeforvintagewatches2732]

You are one of the best teacher on machine operations. Thank you for all of machine shop videos.

[@markferrari9734]

Some people might run their mouth about the first machinist that started the job. But i have respect for someone that recognises that they are in over their head and stop before destroying the part. Hardened steel with an interupted cut can be tricky. Especially if you dont have a stout machine. I wouldnt even attempt that job on my 13x40 at home.

[@KeithFenner]

Exactly, if I wouldn't of been able to getter done, I would of made that decision in the first pass across also. ;{)------

[@not2fast4u2c]

It's a Great Saturday morning when you have a new video for us to watch

[@347chas]

Really enjoyed your videos, better than telly anyday.

[@jimfiorentino7741]

Watching that lathe peel off metal shavings is like watching a campfire. Ya can't stop looking at it. Nice job.

[@somebodyelse6673]

"re-double check again" = "once again, for the second time"? In addition to being a metalworking legend, you're quite the character Mr. Fenner! Please keep 'em coming :-)

[@martinstipp6754]

Ready Set Go big boy drill shaft I glaced at it yesterday thought it was some one else. Nice repair I enjoyed watching. I enjoy your work there are not any machinist shop in my area that show there work like you do Keith.

[@ericchilton3781]

that hole didnt stop you !!!! good work !!!!!

[@daleyurk4369]

Good to see an old style project again Keith! Nice job.

[@jackfrost1031]

I love seeing that new 4 jaw in the lathe. Looks like it's serving you well.

[@johnfry9010]

Nice job Keith , I grew up in a small town and the Machine shop kept everybody working !

[@roscocsa]

Love those close shots of the insert cutting.

[@josephinring]

Great job Keith, amazing to see how well you deal with tough materials and interrupted cuts without any chatter problems. I hope the guy who did the drawing for you took into consideration the wall thickness of the part especially in the snap ring groove, I imagine that this is a very high torque application and those ring grooves are a bit of a stress rise! Thanks for posting such interesting videos.

[@vicpatton5286]

Hi Keith Enjoyed the whole video but the addition of the chicks was a very nice bonus ! :-) regards vic

[@3ltrchris]

An airline and a hole brings the kid out in all of us, or is it just me? As this seemed to amuse you as much as it did me, I will send you a pack of different size holes for your whistleblowing antics. Keep up the great work and videos

[@HEADDYNAMICS]

When we had our well drilled I was out bending the guys ear and I always thought they spray water down the shaft, but he told me they shoot compressed air down it to keep the hole cleaned out. The water obviously comes with they hit water and their desired depth. Thank you for another great lesson Keith.

[@ThCrunch]

Depends on the type of drill rig I think, RC drilling they blow air down to clear the chips at the pneumatic head (and on the mines they keep track of the chips to know what it is that they're drilling). But in other cases they can use water and/or other chemicals (potassium etc to stabilize the surrounding sediment)

[@xenonram]

HEADDYNAMICS Yeah, it depends on the type of drilling. This is much larger than that they would had drilled your well with. They use a bentonite clay slurry to keep the hole from collapsing when drilling with larger drills like this one.

[@marcussho]

Andrew Delashaw air drilling or fluid drilling, both can use this size of drill pipe depending on application and customer requirements.

[@richardhead8264]

I was thinking that it looked like scrap until you said 54:00. I bet that mariner was very grateful for you saving the day!

[@TomokosEnterprize]

I love rough and tough. This is right down my alley from when I was working. Great visit Keith.

[@johnferguson7235]

Random chicken interlude .... LOVE IT. When I was growing up on the ranch, my dad made us go out and pick a chicken for dinner and then slaughter it. He said that we shouldn't eat anything that weren't willing to kill ourselves. He said our ancestors spent 4 million years climbing the food chain and we weren't going to climb back down now.

[@titaniumdiveknife]

that treat in the middle. wow. you are a lucky man Keith.

[@keithlucas6260]

Spent the last sixteen years cutting metal for the top oil companies here in the Houston area. I've cut so many top subs, packers, B.O.P.'s, inflatables, I could do that in my sleep. Reworking is a different animal as everything is sent thru heat treat, coatings, and then stressed by field use. Inserts and companies that make them each have a design, profile and grade that works best in different applications, as no one company makes the "best" for everything. From the get go a CNMG, or even DNMG with a large nose radius would have been my choice, especially with interrupted cuts, and the slowest surface speed. I've done this, and then had to come back and re-cut after inconel overlay.

[@paulduffey7975]

Thank you for another lesson in quality work.

[@kevinbyrne4538]

I'm always surprised by the range of jobs Keith receives: repairing a wood chipper for a tree cutting service ; repairing some guy's motorcycle engine ; making a sign for a local shop ; now, repairing a component of equipment for drilling water wells.

[@SuperYtviewer]

Thank you for the chips and chicks episode. Nice mix of machining and raising. Looking forward to the next video - Annie

[@onemessedupfarmer]

Nice job Mr. Fenner looks good, glade to see your girls made it safe doesn't matter what it is I always see you taking a lot of pride and care into what you do.

[@nameofdane]

Takes a lot of awareness to keep that open-topped oil can upright. If it were on my lathe I'd just dump it straight in the chip pan to get it out of the way.

[@royfcjr]

As a general rule, tapered thread that size are friction welded. I hauled hundreds of loads of drill pipe, and got to watch them install taper threaded ends one time in Alvin Texas. Very impressive and STONG

[@pierresgarage2687]

Hi Keith, Well done in hardened stuff, the worse is the top layer. Don't forget to feed your camera a good breakfast first thing in the morning so it doesn't faint in mid-day during an important part of the job..... lol Cheers, Pierre

[@KeithFenner]

It was on top of the stool with the legs out about 10" diameter and the fan blew it over. LOL ;{)------

[@chrisandyoli]

do you always have to cut /feed from the same direction Keith?

[@ScottPankhurst]

I'm impressed with how well it refocussed!

[@Romecomic]

Since nobody answered your question chrisandyoli you can feed in either direction, a majority of the tooling and a majority of the jobs are right hand tooling and right to left on the lathe. But you can use left hand tooling and cut left to right with some precautions (you putting tool pressure away from the chuck so you need to make sure it is extra secure, use a tail stop). Since most jobs that would require two directional cuts also require taking the part out of the chuck and turning it around, the need for left hand tooling is rather low and often only used on jobs where for some reason you need to chuck a part on one side and cut left to right, or you can complete all operations without taking it out of the chuck and can benefit from left hand tooling. For a good example, take a mushroom. Chucking on the round part of the mushroom would be incredibly hard, but you can easily chuck the stem, Then cut part of the shoulder left to right to shrink the dome.

[@MakinSumthinFromNuthin]

I had a piece of stock spittin out stringy blue bird nests yesterday and getting sucked up around the chuck and work...nasty stuff those chips. Nice result on the repair!

[@georgesweap7]

The screeching sound coming from the tool bit cutting make me think that this is very abrasive metal.

[@4fuzzybear]

SSSSSSSSS AHHHH, I can smell the pipe dope in the room, (oil field for grease) Good memories, but im glad im an old guy now. Keith, Thank-you for all the hours you let us peasants come stand behind and watch. That goes for Adom79 and many others as well.

[@johnleake708]

The old adage my good friend taught me seems to apply: "it was used to much when it was new"

[@stanwooddave9758]

I like that: "it was used to much when it was new". or I guess you could say "They broke the NEW out of it."

[@CarterWHern]

Superb close camera work.

[@jamesfeisley2810]

For a second there it looked like one of my first Cub Scout Campfires; tinder & smoke!

[@fillg]

You caught us laying down on the job

[@PhilsProjects]

hard stuff, right choice of feed & speeds as well as insert geometry and Keith got done what the others could/would not do. 2 thumbs up

[@batch5626]

Another great video thanks again for sharing all your awesome work, you have gotten me out of a pickle countless times. You the man!

[@tinkermouse-scottrussell3738]

I believe it"s called a water swivel. nice project enjoyed this content.

[@matthewheyse8205]

I was waiting for Keith to say "Hey, you've fallen, and you can get up"

[@shortribslongbow5312]

Great video, thanks for sharing.

[@TC-ge3pt]

and...keels over...that was like a flash back for me last night...

[@MrStrangegoo]

Great stuff. The last time I saw aroom tilt lick that was at a wedding with an open bar. Love your vidios

[@ChrisB257]

That sure was a challenge for inserts Keith! I was almost cringing as things squeaked and squealed their way along! Tip temperature must have been incredible. A real Fenner "Gotter done" :-)

[@oldpup4810]

That sounds to be work hardened. If you have ceramic inserts that will help, but all the heat will be passed back to the part. That threaded connection looks to be a 4 1/2 IF sized pin, I milled thousands of them that size when I worked in oil field machine shops around Houston. :)

[@pneumatic00]

Keith, you're a wizard.

[@francismumaugh7376]

great job keith

[@Ron_EZ]

LOL! - WARNING! Man overboard! Man overboard! I hate it when your equipment tries to commit suicide. However, Good recovery; great video keep 'Em coming!

[@lorenlieder9789]

Well done Keith nice work.

[@ralfsautomotive]

Love them yellow faced indicators

[@sashtw]

that moment you look away to sip some coffee while keith turns a well drill adapter look back and he's baptising chicks !!!!!

[@joeclarke9782]

Memorable Memorial Day Keith. Waiting for your next video.

[@davidfe47]

Yipee...for my viewing pleasure with my coffee. Thank you

[@metalflesh1]

No more beer for the camera man.

[@Darryl603]

I see why you quit smoking cigarettes. You just smoke oil now... Great video! Thanks Keith

[@shawnmrfixitlee6478]

great job Keith , That was some hard stuff to cut man .. Thumbs up !!

[@georgeswindolljr.4618]

as always thanks for another great video!

[@titaniumdiveknife]

gorgeous camera work Keithy

[@jeffhoser7717]

Keith, it appears you're threatening my pension check ! [sarc] I know a bit about the stub you're working on ( I used to work for an drill OEM. ) and yeah its probably surface hardened becasue we knew what type of environment it was going to live in. Compressed feed air and an oil mix for the downhole hammer pass through those holes . DAng fine machining and a great video ! As always your commentary is great !

[@fordsure]

wasn't there supposed to be another ring groove for the first bush to go on?

[@onceuponatime9314]

great job kieth good to see

[@mrlithium69]

You can hear the sound of his finger going across the surface finish at 36:40 pretty cool.

[@aserta]

For the camera, if you have some lead pipe around or just some lead bars, put a hook on on end and a length of chain, if you hook that to the center of the tripod and have it hanging almost touching the ground, it will make tipping a lot harder.

[@KeithFenner]

Even if it is up on a stool, the fan is blowing on it and the legs are only spread out in a 10" diameter? LOL ;{)------

[@carlbaumgardt9465]

THANKS FOR THE RIDE

[@Bookerb2004]

Great stuff Keith

[@robertkutz]

keith nice work .

[@PixelSchnitzel]

Keith, don't show Adam how to quickly dial in the 4 jaw! LOL

[@andrewwilson8317]

That is some pretty tough stuff you got to machine there. I have some cubic boron nitride tips for stuff like that. I got them to turn down some big hydraulic rams. Not sure what steel they were but looked like lots of chromium in it to help resist corrosion. Was not nice to turn.

[@63256325N]

Thanks for the video.

[@stevewaldorff4327]

Everybody has their favorite tools and inserts, but if you do more jobs like this one, look into Mitsubishi MP9000 series inserts. I once had to face a 50" dia sprocket that somebody decided was cast iron (it wasn't) and welded all the worn surfaces with nickel rod and hard facing. Kennametal inserts would not last more than about 3 revolutions. I finished the job with only two Mitsubishi inserts in a Ikegai VT110 vertical lathe.

[@stevewaldorff4327]

I used what our Kennametal rep brought to the shop. I blamed whoever welded the sprocket, not Kennametal. Hard facing on the teeth, then nickle rod on the face, welded from the hub out like sections of a pie. The weld was like mountains. I was not generalizing about Kennametal inserts, I was being specific for that job. Kennametal inserts did not work, Carbaloy inserts NO. Valenite inserts NO. Two others that I don't remember, but the Mitsubishi inserts held up, until I could get to a relatively smooth surface. I knew what I was doing, not a newbie. Started running manual machines in the 70's, transitioned to NC(G-code) in the 80's, and full on multi-axis mills and lathes in the 90's. I find Mr Fenner's and A-bom's shop jobs very interesting and kind of nostalgic.

[@carof08]

Steve little bitch keyboard commando

[@rcworks9762]

At 16:33.... Remind me to wear safety glasses while watching you.

[@chrisdavies1265]

nice one Kieth........

[@juggernautxtr]

that screech reminds me of cats,corn cobs and turpentine.

[@sharkrivermachine]

Why wasn't there a snap ring groove for the inner sleeve? It certainly will not move with that kind of press fit, but either will the outer sleeve.

[@WAVETUBE84]

That's some tough material. Dig the chickens!

[@soulcatch]

When I was a kid in the mid 70s I remember an aircraft plant near my house that had long "Stringers" of metal in piles outside their shop. I would guess that the metal stringers were at least 3-4 feet. And they would rust so they weren't aluminum. Just curious if thoughts about chip breaking had changed over time.

[@johnbower]

Excellent job done by someone who understands exactly how to tackle it, but would it have been kinder to the cutting tool if some coolant was continuously flowing onto the surface.

[@CodeAsm]

This looks so cool. I almost want to regret I started programming instead of machining (I did try, but my Dyscalculia dint help with my urge to be too precise.. could not be as fast as you or other awesome machinists.) Some nice work is done here :D great video (I subbed, im liking this)

[@electricsnut]

Hahahah that camera falling over, felt like I was falling over!

[@NikColyerMachineWorks]

Keith; A few months back you did a video about building a steady rest with rollers. You said the rollers were cam followers. I can't seem to find them anywhere. Do you have a part number or at least which car they come from? Thanks Nik

[@oldpup4810]

Threaded joint looks to be what is called a 4 1/2 IF joint. Very common in the oil/gas drilling industry. Machined may of them, both single point and via thread milling machine. :)

[@Strothy2]

poor inserts man those did well on that cut and material, i had worse hardened and interrupted stuff @work but not that big... :D we ordered special inserts for that, still they did not live for long. great video!

[@djeletropopstarify]

Keith Fenner very informative videos keep it up, also I would love to have opportunity to learn such a craft

[@williamsquires3070]

Sounds like a boat whistle, it does!

[@KG-yn9qi]

Hello Mr Fenner Well another tuber maker has been shut down! Besides Adam , Billmaxxx has been shut down by employers.I know it's their right etc. but it's still a blow he did have a lot of subscribers. At least the only one that can shut you down is you,and thank you. You and others have been a great entertaining and learning past time for me. To me you and others,are by my standards, are better than most (all) pro sports. Again hope you and all the others have all the blessing you deserve. I'llsee all of you at this years Bash, yes I'll be there and can't wait to meet all of you in person even double boost what a funny man.

[@GrumpiesGarage]

Keith I think you will find that you can't polish a turd .....but you can roll it in glitter !!!!

[@scottpecora371]

I have a buddy since the 80's I've heard the polish a turd comment, but never the "roll it in glitter! " that's funny!!

[@joetiller1031]

Take note Adam, I thought the chips reached out and got you when camera fell, that is some really hard turning.

[@Rabennase3]

Didn`t you need a third groove, one for the second ring that goes up to the shoulder?

[@KeithFenner]

Followed the drawing for the modification to the T, I believe the working pressure and the .005" interference fit may be enough! LOL ;{)------

[@leegenix]

I was never good at math but, I can relate to .005" and .010" numbers since they are guitar string gauge sizes. If instructors used things that students could relate to, some of us could overcome a learning disability. Also, I never get tired of seeing that gleaming metal after the Cutting.

[@coollasice4175]

A piece of paper is around .004. Is a guitar string that size?

[@leegenix]

The thinnest I have seen for guitars is .007. That's what Billy Gibbons of ZZ TOP, uses. He doesn't like the extra work when he plays.

[@Patriot1776]

Those inserts were squealing like mad cats on that shaft! Sounded like it had been case hardened to deal with the abuse of the job it was doing. Were those the only two inserts you toasted on this job? Nice on the chicken interlude, good distraction! ^^

[@KeithFenner]

Yes the Sandvik failed and the Kennametal only used two edges. ;{)------

[@newandoldtech5634]

But the material was harder at first. Does that has something to do with the endurance of the tool bits?

[@Patriot1776]

Yes. He toasted those two tool bits turning through the hardened outer layers and also turning through the the work-hardened wear rings left from the service damage. Once through all that, the material was softer and easier on the turning bits.

[@titaniumdiveknife]

10:48 mesmerizing stuff

[@joselolopez3635]

genial los pollitos !

[@ElectraFlarefire]

The camera dosen't have scratches.. it has witness marks!

[@gdglock]

Keith, what's the model of your inserts please? I'm burning up sandviks on a work hardened excavator roller axel. Thank you greg.

[@rickybradby1312]

Try ceramic insert tips. Sumitomo or MSC. Your axle might be harder than Keith's job?

[@mikenixon9164]

Very nice job. What happened when camera was tipped over?

[@KeithFenner]

it was up on a stool, the fan is blowing on it and the legs are only spread out in a 10" diameter? LOL ;{)------

[@davidhyer3404]

Im a little drunk and I just fell out of my chair a little with the camera

[@jeremycable51]

My first ever job on at a drilling company was to hand file the threads on one of those took three damn days to get it to go in and thread up smh this was way before I knew a damn thing about machining today I’d make them let me bring it home and recut the suckers two light passes setup with a taper attachment and done two hours max

[@watahyahknow]

could make a bumperring for the lens welded to a piece of flat bar that goes underneat the cam and mount between the cam and the tripod , if it drops the bumper should catch most of the brunt of it

[@gregg4164]

What was the problem with the interrupted cut at the other shop. Improper tooling , speed, ?

[@brianfoley4519]

wow, some pretty tuff stuff!

[@yellowsupra88]

Hey Keith, what camera are you using to zoom in on the indicator in the first part of the video?

[@esoomreltna]

Keith, I understand why you put the tool post block against the shaft to get it perpendicular to the work. But what if the front edge of the grooving (parting?) took is ground at an angle? Wouldn't that cause the groove to be cockeyed? Eric

[@KeithFenner]

The inserts are square on the end. ;{)------
