- Setting up an excavator's pinion motor housing in the four jaw to machine the mounting flange to match the old one. The set up included the use of toe clamps, to help keep it safely mounted on the chuck. ;{)-------
Man that magnificent lathe -a 60 year old that outperforms the younger ones-the operator's skill a perfect match. Once again many thanks.
it's the typical touch-up work where setup time is longer than the machining time
very nice work
Nice footage of the action Keith. Y'all should do a difficult setup like that at the bash and make things interesting! :)
I was thinking the same thing, maybe an oval part instead round.
bah, have them machine something with 1/4" die grinders and fixed selection of bits, no measuring tools until done :))
Keith, you are a chuck MASTER! I'm really impressed with how you take the complications out of this procedure and make it very intuitive! Yet another GREAT video! Keep up the good work😀
I noticed your chuck discipline, you never left key in good man. reminds me of my metal shop teacher, thank you mr summers
well you only do it once, and if you're lucky you get away with it lol
@Kenny Eaton discipline my boy discipline lol when i was learning if anyone left the key in the chuck and walked away the instructor used to throw it at the offending person. they soon got the message.
I doubt this is the heaviest thing that you have turned but it looks like a massive heavy piece of cast iron. Love seeing how much your lathe can handle in terms of weight or length. The cut depths as well. If I tried .050 on my little lathe it'd stall and blow a fuse. The deepest I have cut in steel has been .025, aluminum .030, and hard plastics .035-.040. I love the kind of work you can do with your equipment and can't wait to see the Bridge Port you have acquired running really well. Thanks for all the content.
This is a good video with the more advanced chucking action.
The largest diameter on that cast part bugs me being out of round. Great video Keith.
Keith, Who is we?? 19:21 Is Gollum visiting? Is that lathe your Precious? LOL LOVE the vids!! Have a Great Day!!
Keith... Just noticed the light on your lathe. We have one just like it on our small centerless grinder at work! Good light as it has taken a few"hits" over time. Good safe stable setup. Light cuts but a big bulky workpiece.Excellent.
I'm puzzled why choose to jack the front flange rather than shim the back side.
I bet the mechanic will be cussing a blue streak trying to drop that puppy in place, but will be singing Hallelujah when he bolts it down and puts the pressure to it. Just beautiful!
Overnight in the deep freeze or ice chest with dry ice would shrink it up a bit and make installing easier.

Guessing with that much taken off the pilot shoulder the bolt holes wont be lining up, what are they going to do about that?
Same bolt pattern! ;{)------
I always feel a great sense of relief, when you've 'got' her done, Keith.
I realize that it is turning quite slowly, but I'd be putting on a few zip-ties to be sure the toe clamps and the jack couldn't fly out if some machining process should loosen them.
Very nice Keith. Love the set up and I presume the cardboard disc is to keep the swarf out of the chuck and spindle. Might have to use that idea myself. Great vid as usual.
Another Great One Keith , Gotta Love Those " T " slots In Your New Chuck ! Best Regards..
That leaning guage trick for centering was awesome, only a life long pro would know that one .. awesome.
Really interesting enjoyed it very much, I came to think of, in one of your videos for a looooong time ago you told us that you never take your hand off the chuck wrench when it's in the chuck, I listen to that and learn my self to do the same and now I don't think about it eny more I just do it. Thank you for all you videos I really learn from them also about videoing 👍😊
Somewhat random, and perhaps a silly question, but I'm catching up on videos, and I notice you put a new four jaw on the Clausing, and it got me wondering: if you were going to fabricate a chuck, could a chuck turn a new chuck of its own dimension? Basically, how much chuck could a lathe chuck chuck?
The chuck can hold items as large as the swing of the lathe, which is larger than the chucks being used on them. ;{)-------
Another cracking video Keith, thank you. I am particularly impressed with the close-up shots of the cutting action.
Hi Keith,
the clamping down of the back flange and jacking of the face flange is interesting. you did this to bring the face flange into concentric as much as possible before machining.
would the face flange not flex back when the jack is removed causing the machined work on the face flange now to be out of true.
I would have thought that the jacking would have been confined to the back flange leaving the face flange to be without distortion.
Keith how would you have done this job with your old four jaw chuck without the T bolts?
Good Lesson on "Advanced Chucking Techniques"....! Enjoyed it....
Do they make a double clamper jaw type that could grab the inside and outside diameter at the same time? Seems simple enough, a rectangle with a L shaped slice and a dovetail + clamping bolt.
Rosococsa, I've seen shop made jaws of this type for griping thin walled parts that would distort if griped from just the outside or inside. The jaws are anchored to a face-plate.
I was sure there was something along those lines out there. Never seen em is all :D Thanks!
Roscocsa, since I can't post a picture here, send me an email at aceroadholder@yahoo.com and I'll send you a copy of an old article showing how to make them... very easy.. it's one of those "why didn't I think of that" sort of things.

Thanks!
At 7:15. Would it be an advantage to have a T-nut with two threaded holes, one for the holding down and one for support ...... oh, well. at 8:30 you did just that but with two T-nuts.
I just realized that this part looks an awful lot like that little bit of fun we saw you deal with in round 3 of "The Clash at the Bash"
:)
Hey Keith, when setting your tool, why did you want it to be above center and not ON center? I understand why you were running in reverse so for forward youd want the tool to be a bit below center, but why? Thanks
For safety would be the biggest reason. If something bad happens (turning a welded part, or pushing the tool bit too deep, or whatever) and the tool bit gets jammed in the material, it is pushed away from the part being machined (same reason you should only cut a piece of metal with a hand grinder while holding it so that the sparks fly down and towards you. In this case if the disk gets jammed in the piece, the grinder is pushed up and away from you, or at least it's what i've been taught).
'It's 80 over here'. Love it! :)
Keith, always love your laugh, Cheers from Orlando, Paul
This is high Quality videos! You are doing a great job Mr Fenner
Nice job. Why did you adjust the tool bit above center?
Because I was turning the part in reverse. ;{)-------
For those of you like me who like to see a final part in action, see this for some reference.
How To Replace Excavator Swing Gear Seal
ua-cam.com/video/HU4RwH7RbH8/v-deo.html
This is what it looks like with some of the bits and pieces attached. Takes four guys to remove pinion cir-clip. I believe this is part of the assembly gear that turns the tracks. Please correct me if I am wrong.
This is the pivot motor. ;{)-----
Keith, thank you for yet another great video! I'd like to ask you one thing:
I aim to remove the angle grinder from my shop because i do not like the mess it makes and how it damages machines such as my lathe and mill with the iron-oxide it creates.
Do you have any suggestions as to what tools would work well as a replacement for an angle grinder?
Was thinking about tools such as a sabre (reciprocating) saw and band saw but these only cut, they don't replace other uses such as smoothing down surfaces (flap disc or regular thick disc)
Would love your suggestions
Hahaha, replace an angle grinder. That's a good one.
Niels I don't know how your shop is set up but you could use a simple window fan to exhaust the airborne particles as well as curtains, tarps or similar to contain it from the rest of the shop. It's not a perfect solution but for me it's probably a 80% improvement. Just ideas. Replacing the angle grinder these days isn't really an option, we've all gotten accustomed to grabbing it at least once a day.
James, Thank you for your reply.
I do have one of those areas, but the shop is set up with the project in the middle and the machines around it. So if I'm building a tubular frame, it will be in the middle of the shop (which is not that large) on a fixture table. Of course I can build a curtain around that but that's not always ideal and requires a fan blowing it, through a channel, outside. These channels tend to get hot and increase the risk of a fire. (this has actually happened at a company where a family member used to work.
So in short, I'd prefer alternatives. Now I'm mainly using a sabre saw and high quality files, which takes quite some extra time.
If there are no feasible alternatives to an angle grinder, I'll have to change the setup of the shop, which is not preferable.
Again, thank you for your input.
There are two points to govern a grinder, the contact to the project and where the direction you shoot the debris, the better you subconsciously control that the last, the less mess, where you don't want it. ;{)-------
I see the Abom79 size chuck key hasn't been replaced yet......
2 indicators is THE way to set up anything like that!
Was the old housing non repairable?
is was toast! ;{)------
Hi Keith I really enjoy watching your art skills in action. I built a 3d printer kit and use it for creating medical parts . When i watch your 30 plus years of skill and follow all your cuts with my micrometer but wish your would show your micrometer on the screen for 2 seconds so I can dial up my to see all the action. Great work John
Superlative video shots Keith ! And your explanatory narrative is super ! Not a machinist, but my job involved working with a lot of machinists and mechanics in the field so I was exposed to a lot of good ( and some not so good ) machinists' skills and techniques over the years .
outstanding, as always thanks for sharing your knowledge!!!
Wow, I'm first today. Thanks Keith. Always great to watch your expertise.
Very informitive, showed me where I could improve on my skills in a couple spots. Thanks.
Just curious: How do you charge for a job like that? No, I'm not asking how much you charge, just asking what basis-- by the hour, by the cut, by the job, by guess, by the difficulty?
Keith
From those chips it looks like the material is maleble iron, from my years at Terex corporation, many of our components were made of that material.
De tmp hola muy buen trabajo si no te molesta quiero hacerte una pregunta porque no tapan la bancada del torno no se te arruina saludos
I'm sorry I was only able to grasp part of the Question, Covering the lathe work bench and introduction! ;{)-----
Hello I am from Argentina I have a size of torneria my name is Ariel the workshop is called tmp ago pieces for machines race cars printings esetera and some repairs of machines like lathes I like your way of working and crazy with all the tools that you have In euu you thank you that you answer me and I hope that we can communicate I do not have with whom to change opinions of certain works and I would like to have someone who knows how to work if I can send you some photos of some tapes that I brought a client that when I saw them I wanted to die they are little giant good if you have another way that we can communicate send me thanks a fire
man that's quite the set up!
Keith
Even at that low RPM that jack screw is scary, but I trust that you know that is tight enough!
Nice camera work Keirth!!
Excellent job, I was a Little concerned about that screw jack and toe clamps flexing loose.
Have you ever put a coil rubber hose in a large inner diameter to absorb vibration like Abom ?
Similar ;{)------
the devil is in the details! and they are all in you and your work, keith.
very much impressed,
-toly
That is one tight radius you've left on the flange! .020" Radius on cast is a weak spot! Was there no chamfer on the mating part?
Opening statement: Ladies and Gentlemen, welcome to *termite* machine works. 😂
On site visit. A picture of that would be nice. Maybe during the install?
New chuck key coming soon?
Nice setup, and safe.
great video .i like your video cuz you show all details even it'slong thanks Mr Keith for sharing
Awesome lathe.
Very good video Keith really like the close-ups too. I always feel schooled after watching your projects.
Beautiful job!
nice set up. the times I've heard " that's close enough" really annoying when it's 2 or 3 thousands out. 😠
Zero is an intangible point floating between plus and minus. It still seems nice to think we are on it.
Good video Keith!
good vid and great work
Watching the detail to key removal/safety takes me back to my apprenticeship days good habits are well learnt,good job Keith !!
Good call Keith. I have found for myself to never pass up an opportunity to keep the machines clean whenever reasonable. It it quick and the payoff is good. Just my thought, for what it’s worth.
great content Keith, keep it coming
Nice job setting this thing up! Could you give us the rpm and the diameter, so I could calculate the speed at which this screwjack would come flying at you? Seriously, this thing scares me shitless. I'd probably use shims instead.
I thought he was going to take that jack out before he run it.
Should at least put some duct tape around it, or a band clamp.
Suffice it to say I was painfully aware of the existence of those jacks the whole time...
I know it's purely cosmetic and unimportant, but that dip/flat spot on the outside flat surface would of been constantly tempting me to turn it down.
I was yelling at the monitor about the one indicator hitting the chamfer but i guess you couldn't hear me. hehehe
Great Video Keith...
maybe it's me, but the flange where the holes are looks to be off, by the camera angle.
very nice work.
hi Keith very nice video a lot of great info about how to clamp down defelcult items, but did i see a bozoo when you use the file to round the egde at the end (you cut the same way as the item was running) have a good day/evning
+wonderc66
If you step through from 37:13 , you can see that the lathe was switched back and is actually running anti-clockwise and all is well!
John Greenwood
hahaha ops sorry my bad then it's hard to see what way it was runing
Somebody needs to donate to Keith a Noga ...or two.
Yeah because he is cheap! LOL ;{)------
Somebody needs to donate a spare QC toolholder so Mr F can mount an indicator in it, way easier to use than a Noga.
Mr. Sleep not for nothing, but the sheer speed Keith has, and his dexterity with his tools, shows his true craftsmanship. I am in awe on every video by his hand speed, surety and just plan awesome video work. just sayin
he don't need no stinking indicators, so he dont need no stinking indicator holders lol
(that's a reference to another of his vids btw, just in case you haven't seen it)
Congratulations AGAIN - CHAMP! ;-)
“Don’t want those T-nuts to break” -Keith
I think I head that. T-nuts break instead of bending? That is an important thing to know!
Keith you might next time take some of Your handy dandy T nuts that you have made and use them on the backside of the T slot for support
Nice job
hey, esa forma de usar la cuchilla en el torno...
indicator dove at the jacking screw locations its probly a reeeek...pop noise when those come apart
Another Good one!
keith nice job.
This is a good video to watch I enjoyed it. I probly have some hubs that need work forcmyvokd C-20. I think the comments are good however I think keith could scramble eggs on that 4 jaw Ha
Tough Chucking!
Repaired many of those @ Reliance Electric for Joy Mining Equipment. CNC's would warped the hell out the fit diameters, I would have to indicate on a 56" VTL Bullard to get them running true again. Operators too lazy to stress re leave them. For a finish pass.
Brilliant.....
I think if I was the customer I would ge a price to build up the old part just inc case.
Hello I am from Argentina I have a size of torneria my name is Ariel the workshop is called tmp I make parts for cars race cars presses etc and some repairs of machines like lathes I like your way of working and crazy with all the tools that you have In the US I thank you that you answer me and I hope that we can communicate with you I have no one to change opinions of Certain works and I would like to have someone who knows how to work if I can send you some photos of some tapes that I brought a client that when I saw them I wanted to die are little giant good if you have another way that we can communicate send me thanks thanks an apology the previous message had errors
Hi Ariel, On my web site; turnwrightmachineworks.com I have a contact page, you can find my Email. Cheers, ;{)------
Thanks keith for your time and it is very nice to see a profecional working I am very identified in the way of work good here are 039 dawn time to rest that tomorrow you have to work a hug
I´m sorry if i`m repeating someone else but you shouldn't talk while you use the compressed air.
It has to be zero!!
Please forgive me for saying this
I noticed your breathing is labored, Through your mouth
Recently I was told people like that are not getting enough oxygen through their lungs,
May I suggest you get you oxygen conversion tested,
Both my parents had same and they had cancer, not to scare you, but for your health
Good way to get a screw jack in the face.....nice vid
Dont show ABOM all of your tricks
I need competition, or it's not interesting! LOL ;{)-----
Share and share alike...
Jdeft Defrost check out the episode where keith and abom did the 4 jaw competition... keith won. handily.
Yes he did, but if you watch Abomb set up a 4j chuck you will know he got flustered after dropping the key or would have easily matched or beat Keith. Do not get me wrong Keith is just as good as Adam on the 4J.
Not really...

Your older videos were much better! You talk too much! Cut out 50% of the blab and you'll have top notch videos! Your machinist skills are 100%! Thank you.
Your opinion, thankfully it's not commonly shared.
Cosmo Lean I disagree, myself and a few friends that watch Keith want to hear the "why" he does the things he does, as well as see chips fly. I watch 90% to learn and 10% for entertainment, he's a great teacher and it's very kind of him to give us all his knowledge. I think he's enjoying it also, talking to us is better than talking to the cat all day.
