FIRST time using the self made line boring machine! JCB TM headstock repair.

- In this video I repair another broken JCB TM headstock.
The middle plates, which have been ripped open, are removed. New stronger plates are cut out with the cnc plasma, a bevel edge is then cut for weld prep. They are then welded into position.
Once welding is complete, it’s time for the newly made line boring machine to be put to use! The bearings are aligned so the boring bar is parallel with the pivot pin. The line borer is mounted onto the bearing hub and the tool is set. 3 cuts were made to achieve final hole diameter.
Hope you enjoyed the video!
Thanks for watching. - Věda a technologie
I really appreciate your video 'style' where you have a down to earth no nonsense approach. So many CZcams videos become a glitzy 'show' spoilt by background appalling 'music' where the actual engineering is secondary to the effects. I also appreciate the engineering that you are doing - very versatile.
I totally agree with you but what i hate most are all those 5 second moving camera shots
Snowball is my new favourit since a few months
(And we have exactly the same workshop and same way to organize materials 😂)
Excellent. No "prima donna" bullshit. This is how it is done in the real world. The local farmers don't give a hoot if you've got a shed full of granite surface plates or a hundred grand's worth of shiny snap-off spaniards. They just want their kit back moving gear.
Gday, the line borer preformed extremely well, nothing wrong with the end result there, definitely rigid and once you sort out the bearing housing the setup will be a breeze, brilliant job mate, cheers
I know people who have been in the business for 30 years that don't have the equipment you have and can't turn out the quality work you do. Good job
Keep the videos coming, they are top watching content :)
Thanks! Will do 😁
Custom made tool, doing the real world job it was made for, is great content. Thanks for posting.
Well done fella
I did enjoy that 100% home made line boring machine--good onya bloke top viewing
Glad you enjoyed watching!
Looks like great start on the line boring rig. As time goes on I can see you refining things to streamline the operation. Nevertheless outstanding maiden voyage for the machine. Well done sir.
“Outstanding maiden voyage” sounds so dignified yet do correct
the dial indicator clamp is nice innovation. Perhaps mount a fine pitch screw opposite the clock to slowly jack the tool into place. having done this work before I can recommend broaching out the tool holes to suit standard square shank tooling.
Maybe someone did a bushing job to restore the original pin diameter after wear. In pumps it is common to grub the impeller wear rings to stop them rotating, even after shrink fitting. This would account for the grubs. Any how impressed with your problem solving and the very correct attitude of doing the very best job. Good luck👍
Bloody AWESOME Mate. I normally don't go much on new machine day videos with large wooden crates and shiny wrapping on equally shiny paint work. But this one takes the cake, no wrapping just blood, sweat, ingenuity, skill and massive heap of humility and a real mans workshop with shite on the floor. Just like mine. Don't let you tube subs change you Lad and remember where you started. Humility is a real virtue and you didn't need that new jacket, the cost could have gone towards a boring head. I just love who you are, what you do and how you do it. Keep it up Lad.
Only needed new jacket because the zip had worn out on the old one 🤣
Thanks for the kind words!
Great video! If a prototype worked perfectly the first time then it would take all the fun out of making prototypes. Just a couple of tweeks and you will have a one of a kind custom tool built perfectly for your needs. I love videos with problem solving and your channel is full of them! Thanks for taking the time to produce them for us!
Great Job on the design and build of the line borer. Your tight tolerances will pay off as it wears in.
For the roughing, put it two bits (one for each flange) and finish with the single bit. Awesome job!
That’s a good idea! I’ll try that next time. Thanks!
Do you watch Curtis , cutting edge engineering. Aussie guy. Excellent videos
I do, every Friday.
Cool same here.
Yep, love those two...three. They manage to make polished videos, but keep the real world working shop content.
Do you use FCAW welding wire. Some of the plate thickness and V welds in your repairs it would be suitable I think (saves on the gas) and with a 1.6mm FCAW wire then it would be a few less passes 🤷🏻♂️
Great video again and really pleased the line borer worked so well on its maiden test, but then we all knew it would as the level of engineering told you it would.
Good job !
I have my own line boring outfit..
I myself am not a machinist..
But we do what we have to do to make it work !
Before I bought my line boring outfit I was using My torch and a diegrinder !
Angle grander with a long special bolt and used a worn out grinding disk at the end of my bolt to create a more perfect hole !
Sandpaper wheel on my diegrinder for the final touches !
Again good job on your work !
Oil your bar it helps for sliding in the bearings . And a screw on the back side of the cutter for a pusher screw might help with adjustment .
and maybe a second hole on the bar for a snap gauge . But it looks like a good build just more stuff to finsh up with . You can do that as needed Thanks
Firstly and most importantly it worked. Now you have a good start point to improve upon. Adjustable mount point. Better cutting bits. And does your speed controller go faster. Or can you gear it up somehow. No doubt it will improve as you refine it. Already earning it's keep and doing a good job. I would be pretty happy with that for a total design self build.
Yes, the drill is 2 speed and variable speed. It will go from 60rpm up to 470rpm. I just took it steady for the first go.
A thou and a half is neither here nor there. You’ve done a superb job building that from scratch!
Very nice weld joints.
Awesome man, nothing like a new tool that kicks ass and you made it yourself!
Excellent job all round! I would say once you are happy with your boring bar set up you may consider making to order (if the numbers are right).
Making things work like you’ve done gives immense job satisfaction 👍
More line boring jobs please that was awsome sir thanks very much
Excellent work and workmanship! I feel like the best way to refine a custom built machine is to do exactly what you are doing, use it and make changes as you see fit. You have done great work and I expect your talent will get it tuned to perfection! Thank you for sharing your skills with the rest of us!
good trial run, sounds like a solid game plan, its those little niggles that get you when prototype...👍👍
Great diy line borer! 1 suggestion, is to move the feed controller to the bearing clamp. This would help remove any deflection of the extra weight on the outer end.
Spot on, your work ethics are fantastic, I am impressed of how you approach your challenges. Today I subscribed. Thank You
Nice high standard of welding prep and welding, great first use of new shop made line borer with minor teething problems easily fixed👍👍👍
2 days ago i didn't even know what a boring bar was, today i know how to make one and what to look out for when setting it up!! CZcams is awesome! Thanks for sharing, thats a great machine you made.
CZcams is a pretty great place! Thanks for watching.
Your time capturing on video truly appreciated. Thank you - learning new tricks episodically! Love that this time around, cutting off the broken 'ears', the cut line was the weld prep, too - never thought of that. Regarding the bit adjustment in the boring bar, looking at the bite marks on the bit, the clamping screws are rolled threads with crater ends. If so, grinding or turning a large radius spherical end might help stop the screws walking the bit when tightening. [Robert, way South!]
Awesome! Looks like it did a great job! Looking forward to seeing it in action on upcoming projects.
Very satisfying fix, especially when you know it is stronger than the OEM.
very clever set up!!
It's a very interesting job 🎉
He loves that sledgehammer! See it alot of his stuff . Brother needs some t new tooling , but it just proves what you can accomplish old school 😊
You’re a clever man mate, a craftsmen and tradesman, well done
Great first run of the prototype. Very well done sir. You have now reached the arduous incremental refinement stage where you make the little irritations disappear. 😁🇬🇧👍🏻
Excellent video
Thank you for such an interesting video. Your professional approach shines through at all levels. The new line borer is looking good. So satisfying to send out top quality repairs, I hope your clients appreciate them; I do, having been on the receiving end of a few expensive howlers over the years..
That was a great video.. I enjoy watching you think of solutions to problems... Thank you
great video series with a great ending. thanks for taking the time to produce an interesting series on your approach to line boring.
Very talented gentleman. Thanks for educational videos. Cheers🍺🍺🍺🍺🍺🍺
Very nice job on the line borer and it certainly performed well on its first job. Thanks for sharing.
Nice Machine.👍
You are a true craftsman my friend.🙌
Great job young man. Works great.
You make very interesting videoes, keep up the good work 👌😀
Great job!
What a great solution for line boring. Perhaps using some sort of telescoping tool that inserts through the tool bar for measurement of the bore might aid you. Might I suggest taking a look at how Curtis at Cutting Edge Engineering takes his measurements. He has a channel too.
Worked out well making that 👌
Very nice job. Excellent line borer. A bit heavy but works good.
Try honing the ID of the bearings till u get a slip fit . You can use diamond paste and a diy expanding hone...
Brillant machine, excellent video, you've got it all brother!
And take for testing those bearing out of the mounting and see what happens add one and rins and repeat. Looks very good for maiden drill!!!
Very nice repair, as a back up check you could use the Vernier from the out side of the shaft to the tip of the tool just like a ruler on a centre drill hole. Enjoyed the vid a lot.
Well done!👍👍👍👏🏻👏🏻👏🏻
Good video Oliver, I like your matter of fact approach to the job and your commentary. Sure beats some of the "Talkfest" videos I often watch. Looking forward to your next Video. Keep up the good work. Greatly appreciated mate. Cheers.
Great job
Well to be honest I thought that was great. Your speed and feed seemed OK for the job, and the finish was good. I really admire your dedication to the job, nothing seems to sway you. Kurtis would be chuffed, seeing your line borer. I'm slowly catching up on your previous posts. Be safe, and well 👍
It works well, a few refinements as you learn will occur I am sure but a very nice result for the first use!
Nice ! It did well .
Well done nice job.
Im sure you will have seen it but just in case you haven't check out cutting edge engineering, he has a good video on how he makes his bearing blocks for his line boring machine.
Awesome mate
Hats off mate well done the suspense was killing me. But you had it well under control. All the best on future projects!
Keep it up, your channel is growing, it takes time.
Good job there mate. Strengthened the plates with more bulk about the eyes. Possibly someone could also check linkage function and pressures. Old saying , Cure the Cause, not only the Complaint....
Hey great to see it working 👌🏼 you’re doing well with showing warts n all it video’s. Better to over engineer and refine than break down & cry 😂 look forward to more tooling to make jobs go easier 🤞🏼
If you put a support under your line boering rig, you might reduce the bow you get in between supports.
Super boulot 👍👍
Good job, you are bound to have few teething troubles along the way, however it has passed its first test
19:09 I understand it’s hard to measure the rpm but at a guess you’re shooting appx 500rpm (I’m making assumptions on material etc) but I use 318x90 (90m/min cutting speed with carbide) divided by the cutting diameter (appx 60mm) mate I’ve just stumbled across this I’m very glad you’ve mentioned the 4 part series on the build and I can’t wait to get into it. I have an engineering shop in Australia seldom need line boring so can’t justify the cost off a full ‘purpose built’ rig and have been thinking for quite some time how I could make one. Was even thinking of going down the path of direct (probably geared down) electric drive with a VFD mainly just for rpm control/display. Love the rig and can’t wait to see more!
No, won’t have been that fast. That was in low gear flat out. In high gear with the speed turned down it does 260rpm, so that will have been 150-200rpm.
Only problem with making one is it’s quite time consuming, but in my case that wasn’t a problem as I was just doing it for something to do in my spare time.
Some of the Chinese ones don’t look bad quality and can do bore welding as well.
Just been looking at your video and quite enjoyed it ,I have seen a line borer on Cutting edge engineering and you may get some pointers from that subscriber if you have the time to watch. .I know very,very little about engineering ,just enjoy watching the videos . Will watch again thank you .Bit difficult doing the filming and the engineering.
Need to watch cutting edge engineering Australia cracking lad to watch he has a three leg holder that look a lot easier to put on.. cracking vid to watch you 👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻
Looks like it works .
Not bad for the first go. Few tweaks and fine tuning to do.
Love the video👍 Nice line boring machine. You need a little bit of smarts when it comes to designing and fabricating tools🙂 Nice job, I like it a lot and it looks like it gets the job done!
Well done I’m sure you will fine tune it and make good 🍟
Cannot believe your line boring on those wobbly forks
put your magnet in a plastic or fabric bag, so you just pull bag out and collect all metals. great job
Hi. Great video and really interesting as usual, thanks for posting. I suppose you have watched Cutting Edge Engineering on CZcams. He uses a line borer often. Maybe you can make some of the three welded bar support legs that his uses? I guess I’m not the only one to suggest this, just trying to help. Keep up the good work, you’ll definitely get there.
Regards, Chris and a dog called Mo.
Works a charm, and with a bit more fettling will be perfect. I am wondering if the plasma cut doesn’t harden the steel a bit - maybe a ceramic insert for the first pass, then swap to carbide once thin harder layer is removed ?
Plasma cut edges are nasty. I die grind most of the nasty away so it’s a bit kinder on the tool.
Bring on part 2
My sir Meccanica bearing housings take 2 bearings. Best mounts I’ve seen are the climax ones
You can turn the back of the cutter perfectly flat and use that as your measurement reference instead of the round ball on your cutter and push down a certain distance. Or make a nice fat spot besides the cutting insert for measurements
I’ve cut the round ball off the end of the gauge so it’s a little flat foot. Measuring the tool height isn’t usually a problem, just tightening it down without it moving is the tricky part.
I've noticed in a few of your videos that your torch seems to have its own pilot light :)
Good job for first use time, I think that it would go together better with a drop of oil here and there?
MOOI DING GEWORDEN , EN DOET T GOED .SUPER GEMAAKT 😊
It probably doesnt matter but i never weld or plasma cut anything on my forklift
I always put Some wood in between
Anyway, i would change only the connecting bearing of your drill
The rest seems perfectly fine to me
Have a Nice sunday.
Well done mate. Great job.. I also follow 'Cutting Edge Engineering [CEE]' who are in Australia. Have a look at his videos of his line boring machine. Husband and wife team, Kurtis does all the engineering and his wife, Karen, does all the filming and editing.
Hi Oliver.
Great job, it performs really well.
I'd like to know which material is the bar that holds the cutting tools.
thanks for a great video ! makes me want to build one i saw one being used that had threaded inserts in the bar that carried the cutting tool so yo con slacken the lock screw off and advance it with a lot more accuracy could be an option ? if i gan find it i will send you the details .
PS - speed looks very good
Good job with the line boring, would a chamfer on the edges of the bore help?
What do you use to power your gouge , what size rods and what amps , I've just started using one , they do like the amps !!!
Another great video , showing it as it is not just the good bits , keep them coming
I use my tecarc 400amp welder. I was using 6.5mm rods at about 250amp. It will burn 8mm rods as well. Thanks, will do!
Try watching Curtis on Cutting Edge Engineering from Australia hes done a lot of line boring videos. Might have what you need to know on there.
Is it worth putting a slight chamfer on the bar to aid getting the drive on?
With all them TM headstocks you repair it might be time that you just go balls out and start building your own 😂 Congratz on getting the line borer finished and put to work.
I’ve made one from scratch before for a JCB loadall. Thanks!
It has been sleeved before the grub screws are to lock it into place, an old
trick
I realise this further into the video 😉
