- 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 two, finishing up the machine work on the bar and setting up the lathe, with the jig and making the first cut.

I'm just getting started maching,,disabled coal miner, got a k&t model k mill and sebastian lathe this is a great learning channel thanks man.
Keith
I have nothing to complain about , I know it is a lot of work to produce your great videos.
For you to share your vast knowledge for free is a great service.
Some folks are not satisfied no matter what! Thanks for your knowledge and patience to show us wana-bees how a master does it. Cheers from the left upper coast.
I wish people could appreciate the work you do enough to stop the negative comments. You invite us into your shop and share your approach to challenges and we are privileged to see your genius at work. I Consider you a teacher and appreciate the videos you make and the effort and time you take to do this for all of us who are fans of your work. Take a break when you need to and thank you for all your awesome work, - Keith
As always Keith, your self effacing humor - as in "turn the bar Dummy", along with your infectious chuckle, gets a laugh every time! We've all been there done that, and can fully identify with you. Really gratifying to see some new content from your shop. Wishing you continued success.
Always a pleasure Keith to drop in and watch you do your thing.
Really appreciate your time and effort you put into your videos Keith allot of your viewers do,Don't for 1 minute think a little but of microphone interference is an issue because it wasn't,You have enough on your plate filling out orders in the shop and taking the time to upload what you do and share you knowledge should be enough,Keep up the good work looking forward to the rest of the series as always...Also the relief you put into the bar seemed to work a treat
Muhaa Haloa You are right. I didn't even notice anything about noise. I was too concentrated on work that Kieth presents. We have a proverb that says "keep your attention on priest (in church) and I always try to do that in every time I'm doing any job or watching something interesting. Thanks for the video Kieth.
Keith thank you for the effort and professionalism you put into your videos
Have a great day thank you again.
Hi Keith. You should know that because of you and the other CZcamsrs I am machining happily and safely. Without you guys I would not have a clue. I don't comment often because I really have nothing to offer, but I, too, don't watch television any more: I watch machining videos! Know that I am watching, appreciative and impressed. The more I know from doing work in my shop, the more impressed I am with you guys. Thank you very much for taking the considerable time to make these videos. They will serve way into the future, also in far off lands like mine. Cheers!
Pro tip : you can watch movies at kaldrostream. Been using them for watching a lot of movies lately.
@Reuben Theo definitely, I've been watching on Kaldrostream for years myself :)
Keith
I think some of us might have been concerned you pulled the videos down because you had a crisis or emergency you had to deal with. Glad to see it was only a quality control issue with the audio.
It's always great to see you working with these struts. Genuine big boy's bling, but so much to learn from. Very informative tool-making steps and the setup procedures for boring. Really looking forward to the remainder of the series.
Thanks
I made a boring bar and did some line boring last week and my bar is sort of like a pencil compared to a log up beside yours. Nice work. Thanks for the video.
thank you Keith for the video. I always appreciate you style of teaching.
Absolutely fantastic video about a tool I desperately need to make! This step by step video is really a prize.Great goin Keith!!!!! Thumbs up
Hi Keith,
Interesting series...gives me courage to try this myself when the time comes. Of course, everything you do looks easy.
And thanks for re-doing these for the sound. You are very professional with your machining and with your videos. Thank you for that...that's how I learn so much from you.
Joe
Keith,
You do an awesome job.
You don't have to change a damn thing for me.
Thanks for everything you do for this community.
Looking forward to your next video, warts and all.
For the record, I didn't notice any problems with the originals so they couldn't have been that bad.
John
Parts one and two sounded just fine to me. I can't wait for part three!
you do an excellent job detailing your projects, if it weren't for you and the other top five most of us hobby guys would be lost! thanks for all you do :)
Thanks Keith, I absolutely love line boring, and those t-slots on your carriage are just awesome. Too many great things learned again to list...
Hang Loose and Aloha...Chuck.
P.S. You could sound like "Charlie Brown's Parent's" and I'd still watch every video! You're so kind to share your knowledge with the world, and I'd bet it's an easy gamble that you've helped put food on allot of folk's tables with the education you pass on. Thanks man.
I love the placement of the microphone in your beard! :D
Many thanks for your splendid videos! We all appreciate all the time you spend in order to make them for us and this is one of the best channels on CZcams without a doubt!
Keith that was another great video and as for the scratching noise no big deal. I'm hear to watch the video, not judge your audio. Just keep them coming and we'll all be happy and learning from a master. Have a nice week end.
Another great video, line boring is my favorite. Wish I had those slots on my saddle.
As you can see from the comments, the overwhelming majority enjoy & appreciate your videos. Pay no attention to the whining trolls. If it wasn't sound they were griping about, it would have been something else.
Thanks again.
Thanks for the vids Keith,i am a boilermaker by trade and I really appreciate the detail and love the insight into the way you guys set things up and go about the job at hand.Sitting here at my PC in Brisbane Australia at 1am it's kind of therapeutic when the tool start to cut the job after the set up.
Hello Keith nice work enjoy every minute of your steps as you go along very calming effect also ,easy to follow.
Outstanding work as usual Keith.
Very cool setup!
Great video. Lineboring/trepanning is always trick. I hope the weather on the Cape is nice.
fantastic set up and scaling technique keith mr. fenner, about the only thing youve left for us wreckless eyeballers to figure > 8 thou per @ 450 rpm multiplied by the length of the bore > machine run time per pass. really beautiful workmanship - the cut depth adjustment, etc., im subscribing. thnx
A master at work and i'm learning alot thanks
Great teacher! very well explained, learned a lot there, many thanks.
Keith is back! Finally!
Excellent Keith. I now realise why the chips kept jamming up on the 1" bar I made. There was no clearance around the tool for the chips to escape. I will remedy that now. Thanks for sharing. regards from the UK
Awesome, a old timer I knew years ago had a boring bar that had a twist cut into the bar to remove cuttings. Just a idea that you could add to your bar.
Good video! Very helpful!
keith great part 2 looking for 3 .
I suspect the noise issue bothered you more than the viewers, excellent instructional series can't wait for more.
very nice. Great education, wish there was a index, I know I seen something on your video and I have to check out several to find the piece I need. lol. review is good. thanks again.
Nice set-up.
Frank
Thanks Keith for a great setup lesson, don't get concerned so much about a few defects in the sound, I'm here for the teaching... ;-)
As a hint, the microphone is having an automatic sound level adjustment, and when you get a quiet moment it raises the gain so we get to hear more background noise, maybe by lowering the main gain level it could solve this problem, or if there is a separate adjust on that automatic gain control... Hope it can help...
Pierre
Hi Keith. Great video. Those two brackets are an inspiration. Could you use a pair of tapered cones , with a shallow angle to line up the casting. Many thanks for all your explanations on all your films Richard.
Keith I enjoyed the Break video LOL
Noise what noise! lol Cool setup Keith! Thank you for all your efforts,,, to give great content! :o)
O,,,
Sound is very bearable Keith - main things I notice are -- a slight white noise background which is not too severe, and, the frequency is rather ''topy'' - getting the higher frequencies and not perhaps quite enough roundness with some lower frequencies included. Overall tho - no big deal :). Fascinating as usual to watch the master at work! I want to get a radio mic - will look fwd to you giving some sort of review on that Samson. I can get a Canon radio mic that suits my camera but, at $200 - way too expensive!
It occurs to me that a bullnose center in the tailstock and the headstock would let you center that strut pretty easily in the jig, before you put the bar in. That's assuming the original bores are generally pretty concentric with the castings.
Thank you Keith :-)
Dear Keith, wonderful to see someone having fun at work. I picked up a few good things from your video's. I got a question though, was the inside bore not pre-machined undersize. Normally i get them undersize machined and dial in onto the allready machined bore to bore to final diameter for the bearing. Dialing in on outside casting is not very accurate due to manual grinding and visually improving the casting. Also they do not come always pipe like.
Hey Keith! First a big thank you for the videos you do. They are just great! What oil do you use/recommend for the ways on a lathe or a mill?
I'm going to watch this quick just in case ...
Yeah, I started the video before I got my tea this time.
Keith, really? People gripe about the audio? Sorry. A) I'm here for the content, not the production value. B) compared to most you are already ahead of the curve on you video quality. C) I'd rather have your raw content than some USC film school production with a "I'm not a machinist but I play one on TV production.
ramosel There is nothing wrong with looking out for a fellow machinist !!
Very interesting and beautiful work! Was the casting produced in a local foundry?
cat637d The casting is done in Massachusetts, Prue use to do the castings right here on the cape about 4 miles from here but after his brother died he started to sub out his casting pours to another foundry. ;{)------
Keith I enjoy you're Videos. Thankyou ,My question when line Boring are not the caps machined down a slight amount to enable the Bore to be Correctly Bored? So how do you establish the correct Bushing size to guide the Boring Bars since the existing bore would be not round? Would not this be inacurate? Thankyou
Keith, you are my favorite guy on the internet, and I hate to point out a flaw, but an error, is an error. Your set screw being in the backside not only is a pain in the rear, but also incorrect. Set screws should hold your tool against the bearing surface of your tool holder, they are not supposed to be the bearing surface that takes the pressure of the cutting.
C Connelly In part three I correct that after I set up everything. It was just done by mistake. the wayb I rolled it in the vice to do the holes caused me to loose which side of the bar I was on. Cheers, Keith
Keith, why not center your strut to your bar then indicate both strut od ends with your adjustment screws or are you setting up to the struts cored hole?
i was thinking that tapered cones might really speed set up ..
Thanks again for a great education.
I may have missed it, but did you put a screw adjustment for the cutter or is it just adjusted by a manual push by hand? it looked like you were screwing the cutting bit in?
Also is the final angle of the shaft close enough with the procedure you took to aligning the bore. would there be a time where it would need to be more accurate>
Charles Camenzuli Yes in part one you passed up the close up of the actual insert photo, also in part three you will see more of that option in action. The bores on cast struts are close enough by scale, and if you were setting up machine finished parts you can get them closer with dial indicators, as I have in past videos. ;{)-------
Do you lap the centers on your bars so they set up the same everytime?
bcbloc02 I only scrap centers if they are in need to machine or prove a total true TIR or FIM in an inspection situation. The boring bar can run out and still cut a perfect hole because the swing is constant. ;{)------
I was thinking in case you needed to pull the bar out to measure the bore that way when you resumed cutting any run out wouldn't play into the bore size you were cutting.I haven't seen that process done properly and am interested in how others do it.
Are you relying on the moulder to have the shaft angle set 100 percent in the mould, or do you check that against the lathe bed?
Is there an adjusting screw pressing on the back end of the tool bit in the bar,
to allow for making small advancements of the tool?
Or, is there only set-screws holding it in place?
AZFIREBALL56 There is an adjustment screw in the bottom of the insert seen in the first video, still shot picture, during the intro. ;{)------

Si étiez attentif, aurait remarqué la vis à 25:42
As the bore gets bigger, won't the clearance be greater?
Lee Humes Center line remains the same no mater the size of circle. ;{)------
Keith Fenner Oh. Sorry. I thought it was the trailing edge of the tool you were worried about.
Way to bore that strut. Didn't realize it was that much work.
If this was machine porn, I think the correct title would be "James Beam"...ing. Get it? After a few hundred videos, I thought I was the impetus to the "ring" at the end of your videos: the sound of different metals. Well, maybe not.... maybe so. The "ring" is the sound that is made as you put your moniker/maker's mark/stamp into your finished product! Da...DING!
