More JCB TM310 and 320 headstocks broken!

- In this video I repair 2 broken JCB TM310/320 headstocks. A poor design has resulted in these centre ayes having a very common failure point.
New heavier duty ones are firstly flame cut out of 25mm plates on the CNC cutting table. The old ones are cut off with the plasma cutter using the new jig I made to ensure they’re cut off at the right angle and height. Once cleaned up with the grinder, the new plates then need a bolt hole drilled and tapped and also a bevel cut for welding preparation.
They are then tacked into position with run off plates and a brace across the top to stop them splaying out when welding. The joint and surrounding area is preheated then welded up.
The new ayes then need line boring, another jig is made using the milling machine to drill holes at a set distance apart and the some bushes are made in the lathe to go in the main pivot pin holes.
The jig makes it a lot easier to set the boring bar up at the right centres from the main pivot pin.
The line borer (does anyone actually read this?) is set up and the holes are bored out to size, the same process in then reported on the second headstock.
Hope you enjoyed the video.
Thanks for watching!
Hi Olly. You and Kurtis from Cutting Edge Engineering are up there with the best. Love your work. I very much look forward to your new videos. I'm retired and wasn't even in the metalworking game but I feel like you've taught me a few new tricks. I'd love to be a fly on the wall.
We all hope Ollie can grow his channel to the same level as CEE & his workshop.
Yes, CEE is really good and another good channel is Topper Machine LLC in Wisconsin USA.
I look forward to your videos Oliver.
I learn something new each time I watch your channel.
From kiwi land
Yes, you guys are awesome. Learnt a lot
The differences are epic! Kurtis has total mastery of the tools hers using, olly is accomplishing what he does with Stone Age machinery. The. market places are vastly different. You’d thing the Brits would be exited about new tech but you just don’t see it (exp: Allistare123 and Snowball). Nothing is new in I just wanted to let you new in England.
Yep Olly and Kurtis are fantastic entertainment for an old bloke! Love their work ! Lol😂
An hour of Snowball, made my day. You repaired these to the standard of how they should have been made in the first place, well done Olly.
Because you asked - I do read the full text in each video description. However, I know from experience (by reading comments) that I could be in the minority! Great video content, love the use of jigs for repeat work...
I never read about lineboring on principle but I read all the other stuff
Liked before watching, we all know it’s going to be a belter
Oliver,
After all the troubles you go to, to line bore the equipment for your customers, I hope you also supply (and charge for ) new pins too. Customers will use old pins and your good work goes out the door!! And, as I said, you can charge more for the job. It stands to reason: New holes need new pins, clamps, bolts.
And while you’re line boring, you can turn the pins in the lathe at the same time, cut the clamps, buy the bolts, saving your time but charging for it!
And you can fit and test the pins.
Don't worry about letting your "secrets" out. People will come to you because they can see that you can think, especially outside the box. Too many can't and don't have a clue how to get around problems. I have mentioned it in a previous video, your problem in a few years time will be you have too much work coming in. That will be a good income problem but always remember that you work to live, not live to work. Also no-one on their death bed ever said I wish I had worked some more. Keep the balance right. You are dead a long time. Make sure you have a life, a good life, outside of work and even RUclips. 72 yr old supposedly retired mechanic/machinist in Land Down Under.
Always enjoy watching you work. Thanks for sharing!
Thanks for watching!
Well done mate. Your local farmers are lucky to have you👍🏴
An hour long video magnificent love it😊
God give me strength I love this RUclips channel best that’s out there get rid off coronation street and put Snowball engineering on at prime time xx
You are a big asset to the community, no question about it . We used to have a guy like you in the sixties and seventies who could pretty much fix any bit of farm machinery if it could be fixed.with regard to your low work bench, if you fasten a small hydraulic ram to the bottom of each leg then couple them together to act in unison you could pump them up to suit with a foot pedal or something, not a cheap fix and you’re not made of money but it would be great to see you doing it.😊.
He’s a modern day blacksmith,every parish used to have one.
Good idea about the jacks, how about making a sleeve for each leg so that it could slide outside about an inch to keep its rigidity
Interesting. Engine hoist rams are about $45.
I could see one of those telescoped inside a pipe leg.
You can't tie them directly together or the heavy corner wouldn't rise before the others topped out.
Sometimes the simple solilutioms are the best, some tune that telescopes inside the legs, few holes drilled in each leg for pins, pick bench up with forklift, put pins in and good, fairly common type pf bench in machine reconditioning shops
I've been a Carpenter by Trade my whole life. And I got to say Kudos to you men working in F##'n cold workshops handling Metal all day!! That's not for me! As much as I love wrenching. I would like to show every woman that claims "Female can do the same work as male" this Video... NO you CAN'T Girl! (Well maybe you can.. but the Question is: how long will you last, LOL) Greetings from Germany, Love your Vids. Lots to learn & Decent engineering, no BroBlaBla, Dirty Jokes,loud Music or unsafe BS.! Much appreciated Oliver!
All the calculations and math makes my head hurt ! funny you were perturbed having to chopsaw small bits of bar, because of the table setup for plasma….. well back in the old days !! Not only was it a 2 mile walk to school, uphill there and back,,, options for cutting bar stock was band saw, power hack saw,,, or ….ready “hand hack saw” ! That was when dinosaurs roamed,, and a coke cost 5 Cents.
Good vid. Jigs and shop made tools ! I really like your thinking ahead to making repeat job simpler, faster & more accurate.
very simple and understated channel from a barn on a farm, a bit like Warren's Western Truck channel. Equally entertaining and addictive viewing. Brilliant engineering skills and thanks for sharing.
Been watching for a while, right back to when all you had was a nail file and cheap lighter, it's been great seeing you get better and better tech, seeing you figure it all out then learning new ways to do old jobs, it's all hard work but you're a grafter, but clever enough to not hurt yourself and wear all the proper safety gear.
Weld splash down the boot. Classic!
Olly, what you do with the machinery you’re working with is psychotic! You must stay up late at night trying to figure out how you can put square pegs in round holes. This line boring project was epic as hell
.
Should be compulsory viewing for equipment owners. I for one never appreciated the sheer amount of skill and clarity of thinking that went into what a dunce like me thought was a simple job. Very well done and I can see why WWW recommends you.
Oliver another job well done ! JCB should be paying you for redesigning there equipment.
You can show most people all of your secrets, however very few have the skills and ability to achieve the standard of work you produce
Nothing wrong with Pizza & Chips Ollie, we has exactly the same tonight 👍🇬🇧
I do believe your secrets are good with us, we watch your back. Great job Olly.
Very good work bloke , especially being a one man show. Keep up the good work quite enjoy watching the videos 👍
"I already have my file drawn from ... uh ... other jobs." I feel like this says something about these designs. Great work, though!
Great job Ollie. You are going to be the go-to guy for JCB TM headstock repairs in North Yorkshire ( if you aren't already)👍👍
You might not swing a hammer like Thor, but Thor can't weld. Another enjoyable video to watch of an honest workman's effort. You've obviously built up a reputation for repairing these headstocks.
Yes we read the description. You do a great job of explaining your approach to solving problems. Keep up the good work.
Thank you for taking the time to film and edit such a pleasing video. I guess the ultimate jig will do all three things in on; assist with the cut off, assist with the primary welding and then also be the frame for the line boring. 5*
Yay! Oliver.
Smarter not harder.
A cool trick for painting around those freshly-bored pin holes is to loosely roll up a sheet of paper and let it expand in the bore. Then you can paint all around it and the fresh bore is untouched. Works great!
Very clever the 30° angle tool. 😉
Thank you for sharing, always a pleasure watch your project 👍👍👍👍your explenation are very good,
To think, I used to watch Andrew Marr on a Sunday morning....Great work again thanks for posting.
The air chamfering tool is really neat and I enjoyed hearing what you you were having for tea, more culinary references would be great 😊
When it's all done they will say nice job with no idea the equipment, skill and/or time it takes, kudos to you.
Another great repair Oliver, thank you for posting. I always thought JCB were at the forefront of engineering, however those Headstocks would suggest otherwise in as much it is a known problem, and they seem to be still turning them out.
On a brand new machine I saw at a show last year, I see they’ve started making them out of thicker plate
Jcb agri machines appear to be designed to a totally different spec to the earth movers. Strange given there excavator experience this should never happen
Isn’t it the same the world over? Companies Build their reputations with a Quality Product and then, possibly through pressure from Shareholders, they begin the usual process of creaming back on quality & penny-pinching as they all get greedier & greedier.
Hi Oliver. Just discovered your email videos. Some advice from an old-timer is that your bench height should be such that when you are using a hammer, your forearm is parallel with the top of the bench. Anyway, good job you're doing down there.
Building a nice collection of coat hangers there :)
Sunday afternoon with Snowball doesn’t get any better, clicked the like and not seen it yet, but I just know I’ll enjoy it with a coffee and a dunked digestive. Life’s good for the next hour or so.
Hi great video, just a thought, your new 16mm tapped hole is a great datum point to use/ locate your boring jig. Id make a jig to that👍👍👍👍
Yes, some of us do read the description. As a spoiled Southern Californian I don't know how you survive at 3°C, and yet you still do such quality work under those conditions. It's always a pleasure to watch your videos.
Hello again fantastic engineer watching now
Well done another good job done
Nicely done repairs👍
Another impressive repair!!! Ever consider hiring a shop helper? They could grind the edges clean after the plasma table or switch the lifting straps so you dont have to keep getting in and out of the fork lift. Just a thought to make you life easier and increase productivity.
But then they want paying 🤣
The knowledge and experience would be payment enough for me. Too bad I live in USA
Another top quality job completed ! thanks for sharing your work. Take care Brian from South Yorkshire.
Another difficult job well done !
😢Love the cutting jig. Whos a clever boy.😊😊😊😊😊
I was thinking of moving to UK and starting my own shop 🤠
Great work. The answer is always “Make a Jig” if you do repeat jobs
The trick is to remember where you put them :)
Another great video! Hit a lot of my feel good buttons, I love longer videos, love shop made tools, always admire your thinking process and explination. And also I agree, as a 58 year old I can say with certainty, if you reaise your bench now your back will thank you in 30 years!
Worked in a agric repairs place with a sloping site, the long wall had the benches in 2 steps, which meant a whole variety of work heights which was great for different jobs. Everyone now makes the site level !
Excellent work, those are way bigger than stock.
great job. when i started in the welding bls. 60 years ago we had no tools like yours. that cutting table blows me away. thanks for the show.
Another good fix up! Looks like the JCB owners have found you, I bet there is quite a few more that need your attention! I hope it’s a money maker for you!
I tell you what lad you must have a very rich dad with all the tools you have haha nice to see you can use them
Everything is mine. Bought and paid for outright.
Nice work. And yes, I read the description you write each time, JIm
Great idea with the cutting jigs which made it a lot easier to remove the broken parts. Once you refine that boring jig, it should make the job even faster. Seems likely that you are going to continue getting these headstocks in for repair, because they were under-designed from new.
Thanks
Thank you!
Great job done again making a jig more so for the line boring can be done as a drop on frame which would clip round the main frame work for stability and not requiring tacking in to place which should save time .
Great job as always 👌👌👌👌👌
Ollie, morning... Nice templates to speed up and improve the process... I love how you think... The folks are learning stuff on your channel... Dave
Put your bench up on blocks of wood to make it higher. I put castors under mine but they squashed. My bench weighs 3/4 ton and has about 1 ton of steel stored under it, mainly 30mm round stock. Don't know why but thought it might come in handy 25 years ago!
Beautiful job Ollie. Also cudos on the jigs you made.
that was a good job done Oliver. Nice jigs for your repeating tasks, It's good to see you have plenty of work. and yep I read what you wrote.. and thanks for a most enjoyable video.
My favourite all time Pizza is an oven pizza ! Chicago town stuffed crust deep pan, unpackaged it & let it defrost & rise on a pizza tray, add more cheese & owt else you want on it & then cook it @ 160° in a fan oven. Mint !
Defrosting sounds better idea, I go straight from frozen usually
Great job as always thank you for great content so the next one 😊😊😊😊
Oliver, you are getting better and work smarter. Your forward thinking to purchase tech and use of your skills is great.
You need to patent your replacement parts, that way if JCB actually finally changed the design they'd have to get your approval 1st. As always exceptional craftsmanship, if anyone out there has got attachments for their JCB's suggest they contact you 1st and get what they have upgraded before it breaks down in the middle of a job. 👍
You need two big L shaped jigs. Bottom hole reamed to 40mm to align on the bottom pin and bush and a plum machined edge for the upper pin hole bar to rest against to confirm alignment. Your pin to pin jig will ensure centres are correct. Will also work in reverse for placing bottom pins
a scissor table would be perfect mate ↕️👍🏻
It seems that you definitely need some kind of crane and heating for your workshop. Otherwise, it would seem that everything is ok in the workshop :D
Exceptional job as always. My take though is that your approach is a bit of overkill. I would cut higher, not mess with the curvy "chasis" of the implement, I'm positive it would hold just fine and would be far easier for you. The weak point was just the eye anyway, being too thin, a common design shortcoming. Happy New Year.
Yes I do read your intro and recognise the work too. Well done.
Yes Ollie it's easy done.
Had a few close ones over the years.
Mind yourself and look forward to your next project.
Regards
Alan
Class job as always oliver
And yes I read it
another excellent and enjoyable video
Thank you for another great video. Stay safe and warm.
Great job. Fine tune that alignment rig and that should take some of the curse out of it. Stay warm….
These headstocks on these handlers are failing quite a bit, At least it keeps you busy and improving the finished item quite considerably. Always look forward to watching new videos.
Yes we read it. Nice repair/upgrade, Customers getting a good job done.
Thanks for sharing your creativity Oliver! Well done. Yes after welding the bearing support studs in place, pulls this the bar out center. Then it would be ideal to 'fine tune' the center with setscrews against the bearing insert, as the climax system works.
This is fantastic !! So much skill !
Snap gauges would make your life easier. Interesting vid as always, love your problem solving.
I wish i could send you a photo, i did one of these years ago. I just got two bosses machined 0.5mm over size of the pin. I made one wider than the other, drilled a hole through the end of the pin and through one boss. Radius and preped the existing plate and weld up, no line boring, just fettle with die grinder if required.
Oliver thanks for another cool video. This job was testing you but you got it knocked out. Don't forget to mark your jig parts so it easier to find when needed. Cheers!
Maybe with the improved jig, consider putting the bearings in it for the top hole. Then once you get it in place you can go straight to boring without having to set up more parts.
I did think that when I was making it.
You have turned into a “Machine” I love watching your work and problem solving skills.
Careful bro .. wearing a glove near a drill press I was taught is a no no .. the spinning chip can catch the glove and before you can stop it you can lose a finger or worse .. love your craftsmanship and videos keep up the awesome work .. 😊
Once again a bang up job, very nice.
Excellent repair, I respect your diligence to get it right, and your video and production are great. I think JCB might learn a thing or two from you...
Aye Legend, I read your description of the jobs.👍🏻
I think you called it originally Oliver, a triangular jig on each side utilising the stop plate to locate on could be much simpler to use and set accurately. And as usual an informative video, looking forward to the next one now.
Fascinating to watch.
thanks for taking time to show the right way
Super nice piece of well taught out job.😀
Nicely done better than factory
Enjoyed the video. Great filming. Thanks! Loved the problem-solving.
Nice job especially the fixturing for line bore set-up. I would acid etch all bare metal surfaces before using etching primer then finish paint. It is available at paint suppliers inexpensive safe fast and easy to use applies with hand sprayer like window cleaner let dry then prime and apply finish paint. Ray Stormont
Nice work! I hope your customers appreciate you. They should. Peace brother! ✌🏻🇬🇧🇺🇸
It would appear that JCB might need to redesign those mounting points.
They want to sort the shite black paint too
@@farmernige No point as the paint lasts longer than the brackets anyway 😂😢😭👍🤣🇬🇧
