- Gday, A very generous viewer has sent in a new 130mm 3 jaw chuck for the tailstock chuck I built some time ago, this chuck is replacing the 4 jaw 160mm I had fitted,
This project didn't go to plan in the end but not all projects do, I hope you enjoy the video and thanks for watching, Cheers

Big thanks to Toby for the end screen shot… - Jak na to + styl
Matty, just love your honesty "I'll probably screw it up" priceless. Just remember to err is human, to really f*&k it up take a computer! Also none of your videos are ever boring, always learn something new, even if it's only not to copy the errors. Keep up the great work, all the best.
Gday, making screwups is a part of learning and I don’t mind showing it happens here, if one person benefits outa seeing what I did wrong then it worth showing, I’m amazed at how many machining channels never make a single mistake 🤔, thanks for watching mate
Nothing ventured, nothing gained. Experience was the reward today!
Thanks for sharing 🇨🇦
Ditto!
Thanks mate, I did learn a bit to, Thanks for watching, Cheers
I could see Matty trying to figure out where the chuck came from and the Misses standing there saying “What did you order now ?” Great video,Be Safe!
Thats pretty much what happens mate, Thanks for watching, Cheers
You have high standards, Matty…my motto “Bondo and paint make me the welder I ain’t…”. Cheers!
I like the moto mate, Thanks for watching, Cheers
Hello Matty,
All's well that end well... an enjoyable video, thank you.
Take care.
Paul,,
Gday Paul, not all projects go to plans but thats life mate, Thanks for watching, Cheers
Matty is just right for me. Minimum talking and not repeating himself so he can say Starrett twice in every sentence. Good solid workmanship and always interesting. Please Matty, dont clutter your workplace with CNC stuff. Manual machine tools are great.
Gday, thanks for the kind words, the only cnc thing you’ll find here is the 3D printer, I try to keep the videos straight forward and flowing with minimal crap, truly appreciate you watching mate, cheers
Just don’t turn into abom never ever
Matty. Blame Max Grant he nipped in during the night and tampered with it 😜. 👍🏴
Lol , bugger . Now he will know i have a spare key !
ummm is that what happened
Great video, hate you had that problem, but we've pulled old motors out, customer supplied another one and as soon as you start it up, boom 💥 rod out the side of the engine! Makes you want to throw stuff, cuss and roll it outside and BBQ the POS, but just as we did, you did your best, really enjoy watching you because you show the wins along with the flops!!!
Gday, Not all goes to plan but thats life mate, Appreciate you watching, cheers
As long as you're working and having a good time, who give's a rat's arse if it didnt work out, eh? stay cool
Gday, I don’t mind showing the screwups, we all make’um but not many show’um, thanks for watching
Matty, with those chips at 20:57, silver , blue and purple, you could make a Merkin for the next Mad Max Movie.....
wonderful video, I have been needing/wanting a tailstock chuck ever since I saw Kurtis make one a few years ago,
and this video is the inspiration for one.....thank you so much, Paul
There was some pretty colours in them chips mate, Definitely make a tailstock chuck, not something that gets used everyday but handy when you do, Thanks for watching, Cheers
No mistake just an opportunity to learn.
Thats exactly how it is mate, Cheers
Another good one Matty. It’s great how people send stuff. It shows appreciation that can’t be explained. Well done mate
Gday Steve, the generosity from viewers is truly amazing, Appreciate you watching mate, Cheers
I would have a go at measuring between the bores of the chuck mounting holes and use the constants below to get the hole coordinates. I think it would be easier than trying to find the centre of the transfer punch marks. For 3 hole pcd multiply hole centers by 1.154. Apex hole Y dim is +0.577 multiplied by hole cts, the other two are Y dim is - 0.288 multiplied by hole cts and X dimensions +/- 0.5 multiplied by hole cts.
G'day Matty. Yep lots of machining, which looked good.The new block that you machined looked like a very good quality metal.
Eventually everything worked out well with minimal runout.
With the one you welded, I think if you remachined all the surfaces it would be spot on.
Good video
Thanks for watching Ted, Cheers
Hey mate …
Another very useful video.
I’m thinking that maybe you could swap out the bearings for a pair of bushes, machine up a MT mandrel with thread to suit, and then recut the mounting face from the spindle on the mandrel.
Lot of buggering about I know, but means you can still use the new mounting plate.
Anyhoo…. thanks so much for doing all the extra vid. work Matty.
Regards
Robert
Gday Robert, I might come back to this one day, theres a few ways I could go to fix it really but since I have one that works it’s not on the do it now list although it would be a interesting challenge 🤔, thanks for watching mate
We live and learn if you don't make mistakes you never learn do you good luck ok
100% mate, only way to learn
Dear Matty , I am thinking the issue of concentricity goes back to the welding and how much weld material
was put into the part, and of course, the material stress relieving it self over night. as a weldor,
that looked like over kill on the depth of the v-groove and the all the material needed to fill it.....
as we know, weld material is 'cast material' unlike the 'drawn material' of the base material....
so there will be different shrink rates.....I did thoroughly enjoy the video though and you showing
how you went about getting it done,
Best Wishes, Paul Brown
The extra backing off on your 1and 3/4" drill bit, was probably put on by someone who wanted to drill Brass. , when I was in my trade of Toolmaking we used to back off drills like that to stop them grabbing when drilling brass, it reduces the size of the web of the drill bit. (This is the bulk of the material that runs through the centre of the drill} and as the drill gets ground down from sharpening the web gets wider, so it is a form of narrowing the web.
Hope this helps
Gday, the drill was brought in a jib lot from a factory that was shutting down, I dont know what they did there unfortunately, Appreciate you watching mate, Cheers
Nice one Matty
Thanks for watching mate
Great Job and Good Health
Thanks mate
nice one Matty
shame about the new plate, but jobs turned out a "Gud Un"👍👍👍👍

Kev
Gday Kev, I used to have a shelf of shame but it got to small so I got rid of it, this would’a looked good up there, thanks for watching mate
Very nice job...Thank You...
Thanks mate
Hi Matty. Remember practice make perfect so keep going as you are on the way to making the perfect mistake 😂
Im getting good at making perfect mistakes, plenty more to come to mate, Cheers
Hi Matty. I think that you finished it to final length before you turned it around. Anyway, looks good now as usual. Also really appreciate your honesty. Greetings from Amsterdam 👍
Gday, I think your probably right there mate, we all make mistakes and I don’t mind showing what I screwup, thanks for watching
That was unfortunate. I think that part moved around as a result of residual welding stresses. The boss sure machined like stainless (no idea if it was - but it looks like the chips I get from stainless)- which is notorious for moving after welding. Still - top result in the end. Great video as always. 👍👍
Gday, not all the projects here go to plan, the boss definitely wasn’t stainless but the surface finish was beautiful, thanks for watching mate
I have my fair share of projects that go wonky as well. All part of the fun - and I appreciate you sharing those because there is as much to learn from seeing that as there is seeing the successful final outcome. Cheers and all the best.
Nice job. Steel does some weird stuff when you weld it.
Certainly does mate for sure, thanks for watching
Coffee before I get up and a new Matty video. What's not to like?
Enjoy mate, coffee sounds alright to, I just put the kettle on👍
Great to see you in the shop regularly. I hope you feel as well as you look.
Gday, Id say im not back to 100% yet but feeling alright mate thanks
Never mind Matty. It will probably be of use on another project. Small package on it's way to you with some fresh stickers & a little something out of my drawer.
Steve.
Gday Steve, I received your package today and thank you very much, Truly appreciated and will be put to good use mate...
Great job.
Cheers mate
Hi Matty. Mistakes are there to teach us we are mortal, and to jump back on the horse. Keep up the good work
Gday, we all make mistakes but I choose to show’um mate, it just a part of machining, thanks for watching
Matty the part is not a total fail. You could turn the bearing bores over size and make some bushes to fit and then rebore to bearing size, and see how the runout is then. Cheers
Gdayu, I might revisit this one day and see if I can save it, Appreciate you watching, Cheers
I really enjoy your videos. I love seeing things come together and a product built by hands is still the best way in my opinion. You knew r exactly what's done you figure out the steps without talking the ears off us . Take care n God bless from an old cripple who wishes he could get in my shop and fabricate things.
Gday, I try and keep the videos as simple as possible, sometimes thats not so easy mate, truly appreciate you watching, Cheers
Praise the lord and pass the micrometer! 😂 G'day Matty, I'm fuckin everything up now me dro has died ffs lol
always enjoy everything you do, thanks so much for sharing mate, even the pigeon shit welds 😂
Thanks mate, DRO's are bloody great until they dont work then ya screwed
@MattysWorkshop tell me about it lol
Good one Matty . Birds nest of the week award there !!!! If you follow the same procedure as when i did that C15 pump mount , you will be able to correct that a piece of piss . Cheers 👍
Gday Max, I get another award, ill go back and re-watch that video again mate, Cheers
G'day Matty, a pity it didn't work out, but as we all say "shit happens" mate. I would think it's the welding that caused the stresses and the subsequent 'unwinding' movement of the material. That's all I can think of. If I were to attempt one of those, I think if I had a press that I would make it a heavy interference press size( at least 5 thou or more and heat the plate up to at least blue and press the boss in so that it is gripped very hard. That would eliminate any stresses from the welding. Thinking about it you mentioned the odd hard spots in both welds and I think machining through those hard spots actually caused the warpage as you have unintentionally relieved the stresses unevenly because of what must have been differential cooling in parts of the welds causing the hard spots in the first place. Anyway you've now got a usable revolving tailstock chuck aka Cutting Edge Engineering only a bit smaller lol Kurtis would be proud of you mate! Cheers from London, Sam
Gday Sam, not all the projects go to plan but that’s the way it goes, thanks for watching mate
I think you hit the nail on the head Matty, that even if it didn't work out it was still fun to do. Came out ok in the end. That's what counts. Great video as usual. Cheers Nobby
Gday Nobby, Theres always something to learn from each job even if it doesn't go to plan, thanks for watching mate
That's the way it goes! An idea, to true up the flange, you could have mounted the bearings and set your tailstock chuck mount in the headstock spindle using the morse taper and drive the flange with a dog. That way, the setup relative to the morse taper would be true, bearings and all! All the best, Matthew
Gday, that would work I’d say and I didn’t give that a thought, thanks mate
Normalising = stress relieving, but you'd need a serious heat treating oven. You'd probably need to heat cycle it after welding and again after rough machining all over. You got the result anyway.
Cheers, Preso.
Excellent video Matty, keep'um coming.
Thanks mate, there’s more coming for sure
good video matty
Hello Matty..the machining methodology of this piece is wrong since the rest of the plate is left 1mm larger and after mounting it on the tailstock, a driver is placed on the lathe headstock and thus the two plates start to rotate and that is when you mechanize the exact and concentric register for the plate...regards
You can fix it Matty 😎
Maybe one day I might have a go, thanks for watching
Hi Matty.
Don't be disappointed. Everything can be fixed. Place the buck plate that you make to the tailstock. Put a socket to the chuck to drive the bolt at the center of the buck plate. Make a final cut to running true.
I might have a go at this again one day, I have a couple of ideas how to save it, Thanks for watching, Cheers
great work!
Thanks mate
Being and old country boy from the US. I can see that we all run into problems and just scratch our heads and try something else until we get it right.
I love watching your videos and my wife does to.
Gday, Truly appreciate you both watching mate, Cheers
I know its hard to spend a lot of time working on something. Then, have it slip away. But we all have it happen. If we are honest. So don't beat yourself up. And thanks for all the hard work you put into making content for us. If it was easy, we would all be doing it. So my hats off to you. God bless
Gday, not all my builds go to plan but that’s how I learn and showing my screwups I hope will help others to not do the same, truly appreciate you watching mate, cheers
Great job. . it is very educational when you do everything right and find an error . it helps to realize, somethings are just not in our control.
Not everything goes to plan but thats just a part of it mate, Thanks for watching, Cheers
Gday Matty thats another one I'll have to get to one day as well my lathe has a number 3 morse in the tail stock and I was wondering what size chuck to use I hadn't even considered it tipping forward with the weight so it was good to see how you went about it. Thats always my biggest battle with the lathe getting stuff to run true it's not always easy to do especially when you add bearings into the mix. Top video mate cheers
Gday, with this 130mm chuck it still wants to cock over but no where near as bad as it was with the 160mm 4 jaw, the Morse 3 handles it no worries at all, thanks for watching mate
No mistakes! That means you are not pushing yourself. Keep pushing yourself Matty love the channel.
Thanks mate, Only way to learn, Cheers
The fitting came out great Matty , just think how much easier your work will be with this new chuck. Cheers your a good machinist 😋
Thanks very much mate, The new chuck suits the tailstock much better, Thanks for watching, Cheers
Good morning Matty.
Like I always say, To error is human but a Craftsmen can fix it! I enjoyed watching the video and agree with you it was probably all the heat that distorted it while machining. Heck, build back up, let it cool and heat it up in an oven and let it cool completely and re-machine it. You'll get to practice your welding and have fun repairing it. Love watching all your videos, keep up the great videos and have fun doing them.
Thanks for sharing.😉😉😉
Gday, I might have another go at this one day and see if I can do something with it, Thanks for watching, Cheers
Sometimes it's gonna be "Good Enough" & that's all ya need. Nice one, turned out fine.
Thanks mate
Good video. We are all human & shyte happens. We learn & move on. You jinxed yourself at the beginning. Still taught us all something. Thanks for sharing
Gday, I defiantly did mate for sure, Thank for watching, Cheers
Thank You Matty, cheers from Florida, USA....Paul
Cheers mate
Ta Matty hope all is well Champ
All is pretty good here mate thanks
You got it done Matty. I hope to make one soon, basically the same lathe that I have just a different label on it. Glad to hear that 130mm is a good size, so I don't waste money on a chuck that would be too heavy. Thanks for your honesty and have a Great Day.
Gday, our lathes are identical pretty much, I think the 130mm chuck suits the tailstock, Thanks for watching
Thanks for the video Matty!
Now that you suspect the thermal stress is the culprit. How would you do a third one? Don’t get disappointed, just meditate on the setbacks.
Gday, Probably use the TIG to weld the next one and leave it for a few weeks before machining it id say, Thanks for watching, cheers
It's always nice to know I'm not the only one who learns through the use of materials! I recon you can save the new mounting piece. Replace the bearings with some solid rings and re mount using the MT in the headstock and straighten the cut! If you have a MT sleeve to convert tailstock to head stock.
Gday, Im only self taught and this is exactly how I have learnt, Nothing wrong with making mistakes, Thank for watching, Cheers
@ 9:22 Maybe that 60mm Annular Cutter could have done the job. It amazes me that Annular Cutters are not used more often.😮😮😊
Gday Mark, I knew you were going to mention annular cutters and for good reason, after I drilled it out I remember the bloody cutters so I think I need to pull me socks up mate, thanks for watching
@@MattysWorkshop Just me being a smart arse.
Good thing you could save it in the end. And as you said, this one will be much easier to use than the four-jaw chuck.
Gday Rustinox, I got there in the end mate, the 4 jaw was a pain to setup and to heavy for the tailstock, thanks for watching
Hi Matty, despite the setback, you ended up with what you wanted the the first place - call that a win. Regard, Dave
I took the long way round to get the win mate, Thanks for watching, cheers
Nice outcome in the end, watching that sure beat the 10 1/2 hours I spent driving 650kms to my wife's home village in Northern Thailand today with a few hundred thousand crazy Thai drivers 👍
Gday, don’t think I like to be driving over there mate, pretty wild ride, thanks for watching
LOL - "Dunny Budgie!" I have known similar sayings in the past but never that one!!!
Dirty bloody things they are mate
We all have cocked things up at some point, that's how we learn to do things right. Thankfully I can weld so some mistakes were only temporary until I put it right. In all my years in engineering I call only recall using a tailstock chuck twice. Good outcome with the modified 4 jaw plate. Regards to you and family 👍
Gday, making screwups is the best way to learn, the tailstock chuck is something that gets used to often but handy when you need to, thanks for watching
Hi Matty,
That grind on the 1.75" drill is called "Web Thinning", its to reduce pressure when drilling with no pilot.
I think i would have given the 130mm chuck adapter, a few hefty thumps to possibly settle the bearings in, possibly the part shifted mid turning, or just one of the bores is out.
I'd certainly go back to it, maybe create a drive shaft from headstock to tailstock, and turn in situ?
I have had to hand scrape spindle runout faces, not that difficult, spigot diameter can be reduced, and just clock the chuck in radially.
Nice video regardless 👌
Gday, I might go back and have another go at the piece one day and see if I can save it, not all my projects go to plan mate, thanks for watching
Thanks once again Matty I've just finished making two of those tailstock chucks, I did the second one to suit a 150 chuck, the only difference was I made both out of one solid block of steel, it's come out well . Once again thanks
Gday Danny, I would of liked to make mine outa one piece but like normal I didn’t have a bit of material big enough, thanks for watching mate
Thanks Matty. Appreciated and enjoyed, start to finish.
Thanks mate, appreciate you watching, cheers
The pic at the end is amazing👍 ALB cheers
Gday, Toby my young bloke to that photo when he was fishing the other day, hopefully he’ll keep supplying the end photos now, chat soon mate
Good job in the end Matty. Great surface finish your lathe is producing. The cocked up part will come in, in the future. Don't ask me how I know. Cheers Tony
Gday Tony, I might revisit this again one day, I did have a shelf of shame but I took it down, it was either that or make it bigger, Thanks for watching mate, Cheers
Nice one Matty from a retired Trucky to a VERY good machinist. Cheers from Mourya again.
Thanks mate, appreciate you watching
Gday, I’d say we probably would have passed each other more then once to mate, appreciate you watching
fantastic Matty, love your honesty, No video next week? no worries, I will be here when you do have one, look after yersen mate.
Gday, there will be a video mate, Hopefully you'll enjoy it, Thanks for watching, Cheers
Thanks Matty, it worked out well in the end.
Cheers 👍💪✌
Thanks mate, appreciate you watching as always
@@MattysWorkshop enjoy each and every one Matty, thank you.
G'day Matt,, really enjoyed this one cheers mate
Thanks mate, always appreciate you watching
Well done mate 👍
Thanks mate, chat soon
Cheers mate from the States. I enjoy watching all the same. Hope you can find a new project for it.
Gday, hopefully it might come in handy for something else one day, appreciate you watching mate, cheers
End results are what count, and enjoying it along the way, even if things do not go to plan, always makes it a better experience :)
Thanks mate
G'day Matty dad and I injoyed the video mate 👍
Fantastic mate, great to hear, say gday to ya dad please
@@MattysWorkshop Will do mate
always an interesting video, some you win, some not so.
and now l'm late for work :D
keep up the good work young man.
Gday, Nothing wrong with being late once in a while mate, Appreciate you watching, Cheers
Not a failure. It's a prototype.
Thanks mate
It might have warped when you welded it and the small amount of heat generated by machining it relieved the stress and caused it to warp when it cooled down it might have been worthwhile giving it a gentle heat in the oven and letting it cool before you machined it.but it is still good seeing you on the tools you have inspired me to get a lathe and at least try my hand at machining although before I turn anything I want to renovate the lathe as I got it cheap because it was dropped on its side when the previous owner had it . Keep up the good work as you are an inspiration to everyone who watches you.
Gday, It really is a great hobby, I hope theres not to much damage to the lathe to fix, Thanks for watching, Cheers
Very enjoyable Matty. Shxt happens sometimes. Maybe it was the massive overkill on the welding that send things awry. May have been best to let the part lay for a couple of days and then re-machined the faces. At least you got the job done in the end. ATB regards from the UK
Gday, I might have another look at it one day mate, Thanks for watching, Cheers
Thanks Matt for re making one of these.
Being chatting with a mate on these.
Actually we were thinking could we use a trailer axle stub and assemble and make up a spacer to pack it out flush in the front to fix the chuck to??
Yeah I know a lot agricultural. Just thinking of ease to get and cost.
Sub note:
Sourced that 1045 up here for those dies and getting what I need late next week.
And now looking to make up other dies for my tube roller. Keyway cutting oh fun.
Sourcing a lathe to do all my turning on as the amount I got is I think to much to expect me mate to allow me to do.
And got the material in 4140 for that crank to.
Anyway cheers!!!
Gday, using a stub axle would work but having a big spacer between the hub and chuck maybe an issue possibly, it’s good you’ve found all the materials you need and definitely worth getting your own lathe for sure, being able to make what you want when you want is priceless, appreciate you watching mate, cheers
It came out quite true so good work in the end Matty. That run out on the first attempt is odd though. Were those original bits of steel cold rolled or hot rolled? I have heard of hot rolled steel releasing stress and moving after it has been machined. If that is the case then maybe it needs to sit for some time before dialing back in and machining the registering surfaces?
Gday, I believe it was hot rolled, I might leave it a good while and have a go at trying to machine it again, Thanks for watching, Cheers
If that 3/4 backing plate material was cold rolled, when you cut the corners off, to turn it round, it releases all the stresses from when it was cold rolled.
Not uncommon for it to move up to 5 thou or so.
Might have had a different outcome if you had cut those corners first after you scribed your circle to allow the stresses to equalise, then set about boring & facing.
Round holes from drilling / boring don’t tend to cause the stresses to relieve because the shape is uniform (round) so the stresses are even.
But removing the square corners later after you’d already faced it and bored the centre etc was possibly the issue.
If it wasn’t cold rolled plate then ignore all of that.
Wouldn’t mind a set of those plans myself if possible please Matty, do I ask Max or yourself?
Would it be best to get a 3 jaw or 4 jaw chuck for the tailstock? Indicating in does take time & skill with the 4 jaw.
Keep up the good work. Even a failure is valuable as we can all learn from it.👍👍👍
Gday Ian, I’d say your spot on with the piece of plate, not all projects go to plan but it’s the way it goes and I don’t mind showing the screwups, I suggest using a 3 jaw for the tailstock chuck, my email is in the description mate, cheers
@@MattysWorkshop Thanks heaps Matty, much appreciated mate. My old man always said “a bloke never made a mistake, never made anything worthwhile!”.
He made a few as have I but it’s how we learn & move forwards. And learning to overcome mistakes is what sets true craftsmen apart.
I thoroughly enjoy all your videos, and look forward to every single one. 👍👍👍
Your editing is spot on Matty. Is there no way you can clock that piece back in?
Gday, clocking the part back in sucked up a lot of time and tested the patience to, thanks for watching
With the first one, couldn't you try to pressure drive it with a tube chucked up in the normal spindle chuck and true it up? (or drill a nd tap a hole inside the boss diameter and use a bolt and drive it with a dog to true it up if the pressure didn't work). You just have to make it turn when mounted on it's bearings.
I have a couple of ideas on how to fix it and now I have another one, Thanks mate, Cheers
16:16 is where your messed up the length by switching to a different tool maybe
Quite possibly mate
Could you not put the errant one straight into the morse taper on the headstock end and true it up that way?
Possibly could if you could make it turn as one piece, thanks for watching
4:17 what’s a dunnie budgie
Gday, a dunny budgie is a blow fly 🪰
hy matty did you post the tee bar have not got it yet
Yer mate I posted it a couple of weeks ago, I just sent you an email
ya cant win em all :) but you always try
Spot on mate

Yep thats life mate
Doh! cancel that. 🙄
Very enjoyable indeed. Thanks Matty !!
Thanks mate, appreciate you watching
