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.

Nothing ventured, nothing gained. Experience was the reward today! Thanks for sharing 🇨🇦

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.

You have high standards, Matty…my motto “Bondo and paint make me the welder I ain’t…”. 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!

Thank You Matty, cheers from Florida, USA....Paul

Hello Matty, All's well that end well... an enjoyable video, thank you. Take care. Paul,,

No mistake just an opportunity to learn.

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

Another good one Matty. It’s great how people send stuff. It shows appreciation that can’t be explained. Well done mate

Matty. Blame Max Grant he nipped in during the night and tampered with it 😜. 👍🏴󠁧󠁢󠁳󠁣󠁴󠁿

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!!!

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

We live and learn if you don't make mistakes you never learn do you good luck ok

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

Very nice job...Thank You...

Great Job and Good Health

Nice one Matty

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

Great job.

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

nice one Matty shame about the new plate, but jobs turned out a "Gud Un"👍👍👍👍 atb Kev

Hi Matty. Mistakes are there to teach us we are mortal, and to jump back on the horse. Keep up the good work

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

Hi Matty. Remember practice make perfect so keep going as you are on the way to making the perfect mistake 😂

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

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.

Great to see you in the shop regularly. I hope you feel as well as you look.

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.

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.

No mistakes! That means you are not pushing yourself. Keep pushing yourself Matty love the channel.

Coffee before I get up and a new Matty video. What's not to like?

Nice job. Steel does some weird stuff when you weld it.

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 👍

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.

great work!

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

Sometimes it's gonna be "Good Enough" & that's all ya need. Nice one, turned out fine.

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

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

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.

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

Excellent video Matty, keep'um coming.

You can fix it Matty 😎

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. 👍👍

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 👍

Ta Matty hope all is well Champ

The fitting came out great Matty , just think how much easier your work will be with this new chuck. Cheers your a good machinist 😋

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 😂

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.😉😉😉

Thanks Matty. Appreciated and enjoyed, start to finish.

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

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 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

Hi Matty, despite the setback, you ended up with what you wanted the the first place - call that a win. Regard, Dave

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.

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

The pic at the end is amazing👍 ALB cheers

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 👍

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.

LOL - "Dunny Budgie!" I have known similar sayings in the past but never that one!!!

Thanks Matty, it worked out well in the end. Cheers 👍💪✌

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.

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 👍

@ 9:22 Maybe that 60mm Annular Cutter could have done the job. It amazes me that Annular Cutters are not used more often.😮😮😊

Not a failure. It's a prototype.

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

fantastic Matty, love your honesty, No video next week? no worries, I will be here when you do have one, look after yersen mate.

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 :)

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 👌

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

Cheers mate from the States. I enjoy watching all the same. Hope you can find a new project for it.

G'day Matt,, really enjoyed this one cheers mate

G'day Matty dad and I injoyed the video mate 👍

Nice one Matty from a retired Trucky to a VERY good machinist. Cheers from Mourya again.

Well done 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.

Your editing is spot on Matty. Is there no way you can clock that piece back in?

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.

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?

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

16:16 is where your messed up the length by switching to a different tool maybe

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!!!

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.👍👍👍

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.

4:17 what’s a dunnie budgie

Could you not put the errant one straight into the morse taper on the headstock end and true it up that way?

hy matty did you post the tee bar have not got it yet

ya cant win em all :) but you always try

Shit happens mate

Doh! cancel that. 🙄

Very enjoyable indeed. Thanks Matty !!
