- Creating a boring bar for our line boring jig on the clausing lathe. We demo the making of the bar and how the jig is set up to machine bores on items that are to big to just bore in our milling machines. Part three, After the first part was done and we where cutting on the second strut, we share a little bit about the adjustments of the bits and finish up with a little show of the overall project that we had to create the bar for.

Its not the tool/machines.
Its the setup the operator can create with what's available.
You can create.
You are an inspiration/inspirational.
Mr. Keith, I've just recently found your videos. I'm not a machinist, but deal with them regularly for my job. I have to design adaption hardware for valve automation. By watching your videos, I gain understanding of the machining process without the fear of upsetting my local machinist with my nosiness. I really appreciate your expertise and explanation. Thanks -
Making your own tools is probably the most satisfying thing you can ever do. :D
Thoroughly enjoyed these three videos. Great work! Hope the boat owners realize the amount of work you put into their repairs. Ciao! G
Nice job Keith,that bronze looks the ducks nuts.
Great series Keith! I also enjoyed the slow-mo of the KT, very dramatic.
Thanks
Keith,
Haven't seen this setup used for a while. We had a similar set up on a 36" American lathe for boring air cylinders at Koppers Company.
We used shallow "V" blocks Instead of "C" shaped saddles,with fine thread jacking screws. They were about 18" bore cylinders.
Those C saddles are really nice.
Our setup used a traveling head, and star wheel for feed.
I bored a 1/3 size Case engine frame mounted on blocks on the carriage
of my 13" x 40" inch lathe. That's been five years or so.
Regards
Kap.
very cool Mr Fenner, thanks for the shows!
Sweet! Being retired and all, it's something I'll not likely ever do, but I value the knowledge irregardless. Thanks for the lesson, Mr Keith. Salute!
Excellent series Mr Fenner, rivals anything being put out by the networks today. Educational and informative. and your video work is outstanding , something for anyone to aspire to. Thank you !
Excellent series Keith. Some great tips and advice throughout. Look forward to the next one. regards from the UK
Thank you. You've inspired me to look at boring bar projects in a new way.
I'll be coming back to this series in the near future I'm sure.
Hugs A
Keith, your videos are some of my favorites. Hope your getting some boat rides out of the work your doing. I was the mechanic at a mercury dealer that happened to be right on the water a few years back and one of the perks was going on a boat ride every time I finished a job to test run the boat. Loved it while it lasted.
That slowmo shot at the end is frekkin awesome =)
Keith,
I enjoy your videos so much. This one is no exception.
Top quality video, top quality audio, top quality workmanship.
I love those boring bars. I keep trying to get guys here at work to us our lathes like that. The shop supervisor just doesn't see the value.
Thanks
John
Thanks for another very educational series. Your videography skills are coming to par with your machining. I look forward to the next series.
I really enjoy your informative videos Mr. Fenner, especially when you have to design and manufacture your own tools to do the job! I'm amazed at your talent.
Thanks Keith, Another good one! Great to see machining, even better learning how to make tooling.
Nice series, I was building a bar before this, you have given me much insight. Thanks for posting these video's we enjoy them very much
Great set of videos.
Really liked the ultra-slo-mo (with trollying/panning to boot) on the horizontal mill. You can really see what's going on. Next you will be fitting a micro-camera to one of the teeth so we can see actual chip formation.
Excellent video and cool slow-mo. Very cool touch. Thanks for posting.
I congratulate for their video,these devices that we are turning ever we have to study and plan for certain services,very good.
You're playing that Jamaican-style beat and all I can think is "The broach in the mill goes 'round and 'round, 'round and 'round, 'round and 'round....." :)
Always a lesson in watching you work.
Thanks for another great video! Boring should be renamed, as it's one of the most interesting operations. My lathe doesn't have flats on the saddle for the same setup that you have, but I plan to adapt a mount somehow. Being able to linebore in the lathe is so handy.
Hi Keith, seen the "in pressed video", fun to look at, but, this serious stuff is why I keep coming back learning and enjoying so much, thanks for putting it up, Pierre
pierre beaudry Yeah I know and I plan on keep putting videos like this up, even if once in awhile I have the need to share feelings! LOL ;{)-----
I have no idea how much effort it takes to create these videos. Seems like there could be another one in the series between two and three. Perhaps showing installation of the bearings. But for whatever it is worth, I like seeing all of the boring detail of making your items. Thank you.
EBenderTheRobot It was about the bar and I just added in some of the final project photos just to satisfy a hint on the total job, I used the bar for. I have a lot of other videos from the first videos in my collection, which show bearings being pressed in and all the details I may have left out of this video. Thanks for asking. ;{)------
@Keith Fenner Hi Keith new to your channel. Wondering why no coolant cutting the bronze strut but coolant when making flat cut on bar. Doesn't coolant prolong life of cutting tool and maintain cut consistency thru bore? I plan to watch more of your videos, lots for me to learn.
Great to watch the 'master' at work, gives me inspiration do get 'er done!
Great video Keith
Whatever you have done with the wireless mic it's a vast improvement , well done in sorting it out.
That bar performs well makes my 25 mm bar look puney
Looking forward to the next project

Keith,
Been gone for a while. Just catching up. Love that laugh. “Ha ha… where did that screw-driver go? I just had it!” (Think that was part two.) In contrast, I would use creative and corrosive colloquialisms that would singe eyebrows and traumatize the young. I remember the same calm chuckle, when your mill-bit slipped from it’s collet and dug it’s-self in deeper than intended, when you where putting a keyway into a four inch shaft. No problem you said, I’ll make a custom key. I call that relaxed competency.
Thanks,
Brad
excellent job , well done . good info within the three parts on making a tool to do the task at hand. I am sure you will get a lot of use out of that boring bar with the work you do .
Beautiful job Keith! You are lucky that your lathe has those T-slots in it so that you can use it for line boring like this. I have done similar setups on the horizontal mill, but never on a lathe like this.
Keith Rucker - VintageMachinery.org Thanks Keith, what helps make this lathe a keeper! ;{)------
Keith Fenner Keith, have you thought about boxing your brass/bronze cuttings and sending them to the other Keith so he can do his great casting projects for his safe and the choo choo?
Great videos.
Pro trick : you can watch series on flixzone. I've been using it for watching a lot of movies these days.
@Roman Major Yea, I have been watching on flixzone for years myself =)
thanks heaps for all your teaching
Super cool setup , I enjoyed the 3 parts Keith !!
great show
Irie, mon! Tanks for playin' sometin' from de islands.
Good work Keith, nice camera work too.
Parabéns Keith fantástica explanação
Great work.
nice work Keith
Enjoyed the series Keith. Probably copy your boring bar to use in a line bore rig in future.
Colin ;-)
Thanks Keith.
you are awsome
Tidy work!
nice slow shoot at the end. maybe You can make more of this?
Don't know how you got a dislike on this series but i suppose there are some tools out there that do this for something to do.
In my opinion this was an excellent video on line boring .

Obviously not a machinist OR one of the the 'know all' brigade.I am in England and Keith brings back the memories I have in the 1950s and 60s when I first started in a machine shop, the skills and knowledge that the old timers had and used to get
any job done without the aid of computors and 7th axis CNC machine centers.
setting up dial indicator for exact height.. rings in oversized to slip on bar. allowing you to get indicator adjusted to zero on the rings and then take a measurement of your cutter height.. look at tobin arm boring bar setting tools.. with the double reading micrometers for ideas.. should be really easy for you to create.. getting sizes even closer.
Beautiful pieces Keith! What is the story on the round drive lugs on the K&T rather than the normal square? When I get my HBM going maybe I will be able to test out which bores better a hard bar or a soft bar. I have heard conflicting things about what is better.
bcbloc02 Round lugs are fast to make and started out to be a quick temporary drive and 20 years later, still doing the job. ;{)-----
Onward and upward.... Thanks Keith! :o)
O,,,
Excellent video as always Keith, Thank you. And the slo-mo at the end ? Aawww, that is practically porn. C'mon now, admit it!
If the Cutlass bearing is pressed into the strut up to the shoulder, How will it be removed later?
Great video on the whole project, thanks.
Rick
Rick Swanberg that is exactly what I ask, but some engineers are set in their ideas. ;{)------
Keith, really nice video. Given that you had to make the bar to do the job, I was wondering if you pass on at least some of the cost of making it when you priced out the job itself?
***** investment just for the shop and tooling, one investment in your working less harder on the next project. ;{)------
clever
keith 1- 3 was great what is next can't wait?
Hello , great video , and the three of them , i have a similar but not really quite situation and i would to ask you how would you go about it , we gave a pipe of 45mm od 35mm id and two bearings have to be press fitted of 41mm so a 40.95 to 40.90 pocket has to be made , those dont have to be exactly concentric with od but have to be concentric and parallel to each other , as i imagine it a 32 mm rod is required to clear the 35 mm id but there is no way to flatten the bar firstly cause there is no way and secondly i think it will weaken it , so we cant put an indicator on it , how do we measure the hole while still on setup ?

hi Keith,
thanks for the wrap up on this series. interesting to say the least,..... would it make any difference if you used a 4 jaw chuck to run the bar instead of a 3 jaw (runout issues) ?
cheers
mike
HolzMichel The swing of the bit never changes, whether it is .100" out or zero. The part passes over a stationary bit position. Not an issue. ;{)------
Keith Fenner
ok, makes sense, thanks :)
What are those round shaft looking things behind your lathe against the wall? Im referring to the camera angle from about 6:03 and on. Really curious.
jesse foulk Those are my tracer patterns for various projects and shafting ends. ;{)-------
Hi mate.
I seem to remember that you had done a prop shaft support like these before. What was the reason that you made the bar this time, rather than before? It is a nice bar though. However, it must have been quite an investment.
Marcel.
Marcel Timmers This set of struts had a smaller bore and wanted to create a bar for small applications. ;{)------
Ok, fair enough. I did think I saw you wrestle with an other one, and I was right. Thanks Keith.
Hello Keith, my name is mario and i have a question. Would it be possible to add a second cutting tool lets say two inches behind the first one so as to take another .015 on the same pass
Is their a reason you don't use "scroll" chucks?
YOUR VIDEO IS A REGAL !!!!
