Tailstock Chuck Re-visited

[@metalac78]

Hello Matty, you'll be surprised when you see where I'm watching your KZbin presentation from. I'm also an old turner, who has been retired for a long time, but it's in my blood that I can't do without metal and I watch all your innovations and meticulousness. I always say that metal processing on conventional machines is an art of knowledge. Current production on CNC machines is mass production! Operators, as they are called, are not turners or millers, but workers who just stand next to these machines. What you know is no longer taught in schools today, at least not here. In my opinion, that's all the beauty of processing when you have a plan and work according to it! Just keep going, in my opinion it keeps a man alive in our age when he does something that fulfills him and maybe earns something, at least for electricity and materials! Greetings from Zlatko from Croatia (Europe)

[@MattysWorkshop]

Gday, it would be great if machining was taught more in schools like it was years ago, I had a fantastic teacher at school that taught us well and when I left school I brought my first lathe, I don’t believe I’ll ever see a cnc in my workshop, they have there place but it’s not the same as feeling the machine do what you want it to do, truly appreciate you watching and commenting mate, cheers

[@MonikaBowstead]

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.

[@MattysWorkshop]

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

[@nigelroberson8911]

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.

[@MattysWorkshop]

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

[@marley589]

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.

[@MattysWorkshop]

Gday, Truly appreciate you both watching mate, Cheers

[@williamkey678]

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

[@MattysWorkshop]

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

[@TedRoza]

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

[@MattysWorkshop]

Thanks for watching Ted, Cheers

[@ypaulbrown]

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

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

[@MattysWorkshop]

Gdayu, I might revisit this one day and see if I can save it, Appreciate you watching, Cheers

[@Rustinox]

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.

[@MattysWorkshop]

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

[@acmemachining]

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.

[@MattysWorkshop]

Gday, our lathes are identical pretty much, I think the 130mm chuck suits the tailstock, Thanks for watching

[@pandim6774]

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.

[@MattysWorkshop]

I might have a go at this again one day, I have a couple of ideas how to save it, Thanks for watching, Cheers

[@bostedtap8399]

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 👌

[@MattysWorkshop]

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

[@RB-yq7qv]

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

[@MattysWorkshop]

Gday, we all make mistakes but I choose to show’um mate, it just a part of machining, thanks for watching

[@allenbrown7820]

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!

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

[@MattysWorkshop]

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

[@thepagan5432]

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 👍

[@MattysWorkshop]

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

[@MatthewTinker-au-pont-blanc]

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

[@MattysWorkshop]

Gday, that would work I’d say and I didn’t give that a thought, thanks mate

[@Preso58]

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.

[@davidlegault9745]

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

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

[@dannygreene4594]

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

[@MattysWorkshop]

[@stephenperry5849]

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.

[@MattysWorkshop]

Gday, Im only self taught and this is exactly how I have learnt, Nothing wrong with making mistakes, Thank for watching, Cheers

[@samleigh7817]

[@D40..]

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

[@MattysWorkshop]

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

[@thigtsquare950]

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.

[@TrPrecisionMachining]

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

[@RobertBrown-lf8yq]

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

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.😉😉😉

[@MattysWorkshop]

Thanks mate, always appreciate you watching

[@samrodian919]

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

[@MattysWorkshop]

Gday Sam, not all the projects go to plan but that’s the way it goes, thanks for watching mate

[@johnmoore1025]

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.

[@MattysWorkshop]

Gday, It really is a great hobby, I hope theres not to much damage to the lathe to fix, Thanks for watching, Cheers

[@StuartsShed]

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. 👍👍

[@MattysWorkshop]

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

[@StuartsShed]

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.

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!!!

[@MattysWorkshop]

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

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.

[@MattysWorkshop]

[@thehobbymachinistnz]

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?

[@MattysWorkshop]

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

[@philmurray1359]

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

[@MattysWorkshop]

Gday, clocking the part back in sucked up a lot of time and tested the patience to, thanks for watching

[@ianmoone2359]

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.👍👍👍

[@MattysWorkshop]

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

I thoroughly enjoy all your videos, and look forward to every single one. 👍👍👍

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

[@MattysWorkshop]

Possibly could if you could make it turn as one piece, thanks for watching

[@joedowling5452]

Not a failure. It's a prototype.

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

[@MattysWorkshop]

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
