Well Drilling, Coupling MOD

[@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. ;{)------

[@newlifeforvintagewatches2732]

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

[@Pyrrhic_au]

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.

[@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.

[@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.

[@johnfry9010]

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

[@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 :-)

[@daleyurk4369]

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

[@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!

[@jackfrost1031]

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

[@jimfiorentino7741]

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

[@roscocsa]

Love those close shots of the insert cutting.

[@TomokosEnterprize]

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

[@SuperYtviewer]

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

[@not2fast4u2c]

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

[@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.

[@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

[@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

[@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.

[@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!

[@347chas]

Really enjoyed your videos, better than telly anyday.

[@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 ;{)------

[@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.

[@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.

[@paulduffey7975]

Thank you for another lesson in quality work.

[@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 !

[@vicpatton5286]

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

[@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.

[@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

[@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.

[@tinkermouse-scottrussell3738]

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

[@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.

[@ericchilton3781]

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

[@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!

[@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. :)

[@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

[@shortribslongbow5312]

Great video, thanks for sharing.

[@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" :-)

[@TC-ge3pt]

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

[@joeclarke9782]

Memorable Memorial Day Keith. Waiting for your next video.

[@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

[@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.

[@georgesweap7]

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

[@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

[@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.

[@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."

[@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. ;{)------

[@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.

[@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.

[@Darryl603]

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

[@lorenlieder9789]

Well done Keith nice work.

[@shawnmrfixitlee6478]

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

[@JOHNPHUFNAGEL]

Great job Keith. Do you do any spray welding and if so why couldn't that process been done on this part? Why couldn't the other shop finish this piece?

[@KeithFenner]

I don't do flame spray, but have worked at shops where we did, the best was ceramic spraying on marine shafts. They were just gun shy on the material hardness, playing it safe. ;{)------

[@fordsure]

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

[@wstgdh]

Hi Keith, why you are not using coolant of any sort? Could solve a lot of problems...

[@KeithFenner]

I haven't the room for shielding and access to my attachments I run off the back all the time. ;{)-----

[@wstgdh]

I see, thanks for reply. At such low rpm, and far away from a chuck splashing will no be a problem, I suppose. But you obviously found you way over the years :) here at the other side of the ocean we use coolant almost all the time, while guys at US prefer to burn some cutting oil, as I can see from the videos :)))

[@stuknda80z]

wonder how they would handle that in the days before the insert tooling, could material that hard be cut with HSS

[@KeithFenner]

They would anneal it do the machine work and then re-heat treat it, after using cobalt tooling. ;{)--------

[@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)

[@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.

[@rickbcfl]

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

[@titaniumdiveknife]

gorgeous camera work Keithy

[@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 ;{)------

[@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!

[@gibbsey9579]

Hello Keith If you were asked to cut that taper thread, would you use the taper attachment? Ken

[@KeithFenner]

most likely! ;{)------

[@KG-yn9qi]

Why didn't you have to cut a snap ring grove for the sleeve that butted up to the shoulder ?? I also don't get how this works,as I have worked many years on drilling/work over Riggs. the shaft is for the swivel atop your drill string, okay so the weight of the string hangs from it. as from what I see if you do that you'll pull this shaft right out of the outside case of the swivel head?? Unless he has a top drive that holds and rotates the drill string pipe. So this screws into the top of the top drive.So it is like a (chick-sand brand name) type of full rotating assembly he hooks his Kelly hose to. So question is to prove this is the tapper pipe thread on end of the shaft,left handed??

[@KeithFenner]

I didn't ask how it fits or seen it in place on the rig, so I have no information there. The spec. drawing for the rubber seal kit he already runs on his spare swivel and we are performing on this one, doesn't ask for the third groove which would be inline with the port hole as well. ;{)------

[@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 ;{)------

[@Steve_Just_Steve]

Why would you not want to use coolant on a job like this? Is it hardened? Not supposed to coolant when machining hardened parts right? Or is that only when using ceramic inserts? Thanks in advance to anyone willing to help me with some answers.

[@KeithFenner]

I don't use soup on my lathe. ;{)------

[@Steve_Just_Steve]

Is the benefit just not ever worth mess or why don't you? If you did would it be appropriate to use on a hardened part with regular inserts? I'm really just trying learn. Thanks Keith!

[@KeithFenner]

Room for splash shields and access to all my attachments on the back side of machine, keep it from being an importance. ;{)------

[@ralfsautomotive]

Love them yellow faced indicators

[@tedsykora1858]

I wonder if it would have been a good idea to actually know how tight the press fit would be ahead of time by checking the ID of those sleeves before hand? Turned out great but kind of scary?

[@KeithFenner]

They had .004" to .005" press fit and when the customer came in to pick up the job, I installed them, with heat and green loctite. Photos will be posted on Facebook. ;{)-------

[@tedsykora1858]

Keith Fenner nice to see all assembled or back in service. most of the time we only get to see the machine shop work .

[@KeithFenner]

Thats because I don't follow the job out in the fields after it leaves shop, once in a great while I do get that chance and do take the cameras along. ;{)------

[@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. :)

[@mrlithium69]

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

[@pneumatic00]

Keith, you're a wizard.

[@yellowsupra88]

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

[@W4BIN]

This has left me wanting, wanting the third groove, the one for the first ring that goes up to the shoulder? (as Rabennase3 said first) I assume the 5 mils of interference means that the rings must be heated to be installed. ?

[@davidaarons2488]

Hey Keith, nice job. That was a tough cut, turned out good. Just curious did you cut that with the heat expansion compensated for? How are the chicks doing? They look cute. I also see you are in R&D for camera equipment durability, lol. God Bless Ya Dave

[@KeithFenner]

It sat over night before the final cut so it was normalized in temperature, all the chicks are still doing great, I was surprised the camera crash held up pretty good, will be shopping for a better camcorder, but not because this one is getting the job done! ;{)------

[@fastst1]

For smokey jobs, would you think about using your vacuum system to draw the fumes outside?

[@pandaward4671]

Are you still going to make a new cross slide screw to get rid of the slop in it?

[@KeithFenner]

Yes, still on the list of things to do. ;{)------

[@matthewheyse8205]

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

[@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.

[@jacquespoirier9071]

just looking at chips tells me that this material is very hard have you an idea of the rockwell hardness of this material

[@KeithFenner]

No ;{)-------

[@marcussho]

Jacques Poirier most API drill parts are around 40HRC, they do use a lot of hard banding near the connection pin(exterior thread) or box (interior thread) so care must be taken. Some hard banding contains tungsten carbide particles.

[@jacquespoirier9071]

thank you, it's a a domain of application that I don't know but by the way chips are produced, I know that the material is somewhat hard. At about 40 RC, the material is thoughter to machine but the behaviors of the material is usually better suited to produce closer tolerances and better finishes by cutting and by grinding

[@gregg4164]

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

[@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.

[@onceuponatime9314]

great job kieth good to see

[@djeletropopstarify]

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

[@hootche1]

keith , why do you use oil for cutting, i was allways told to use slurry water / oil base water.

[@KeithFenner]

I don't have room for splash shielding and hassle to get to the attachments on back side of machine. ; {)------

[@hermanwulf771]

Could you have chamfered the center drain hole to ease the transition of the cutter as it passed over it?

[@n3omoathome139]

Why did the other guy have so much of a problem with the interrupted cut that he abandoned the jub, but you had no problem with it? Is that Fenner Magic?

[@joetiller1031]

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

[@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
