Nice I grew up in the UK and after Uni (engineering) I moved to the US. I got 6 months of training on lathes and mills before they decided I wasn't allowed to use tools anymore. In retirement I have just now bought a brand new lathe and mill which cost more than my first house! I have yet to use the steady and I want to build a tailstock chuck and just happen to have a spare 8" 4 jaw under my bench. The thought of a piece of old soil pipe in my new lathe is a bit horrifying but highly entertaining..:)
Hi Frankish, I only did a year on lathes and mills myself before I moved onto other things so this has been a rediscovery for me too. That's quite an investment to buy new but at least you won't be repairing for the first 3 months. My tailstock 4-jaw build was pretty crude - others would have used taper hearings. But mine is only used occasionally and, as you see, it works perfectly well for my home workshop. I'll use any metal that's free. Cheers
Hi PJLee, yes it's often a mistake to make witty comments about politicians in the vids - when I made that light hearted joke we could not have imagined what was to come ...... Thanks for watching.
Yes, and now I have his number I can lobby for tax relief on Worksop upgrades and I'm sure he will get Rishi to fix it .... (For non-UK folks, there is a bit of a lobbying scandal at the moment)
Hi Robert, I know the one you mean but actually I got the idea from a UK channel called 'David Wilks' - he does a lot of heavy trepanning but in one vid he has work between two 4 jaws. Cheers.
Hi stukyu, when you mention a politician or other personality in a vid it always leaves you 'hostage to fortune'..... it's always safer not to try and be funny because sooner or later it usually backfires. But hey, we can't be careful about everything - that would be boring. Cheers
How about making some cast iron rings for "Your hydraulic cylinder", there's still plenty of them in use. Great set-up, hope it doesn't rain. Thanks for sharing.
I am leaning toward a 5"chuck too. I have a bigger lathe with a MT4 on the tailstock and a MT5 on the head. I think if i use a MT4 live threaded center with triple bearings I should be ok. Some people use wood chucks because they are lighter and dont have back plates. I would not trust the jaws. What do you think?
Hi Bernard, I think it really depends what you want to use if for and maybe how much bed length you have. If it is really just to be used as a replacement for a large pipe centre then any sort of clamp that spins might be fine. However there may be many cases where you need the precision and versatility of a machine chuck. I've used my MT3 4-jaw chuck in both the tailstock and the headstock. I've drilled index holes around the backplate. You may wish to hold both large and small items - like I held the end of a small motor armature (only 8mm diameter shaft) which did not have a centre. My chuck has been one of those tools where again and again I've thought "oh I could use my tailstock 4-jaw for that" for things I never ever thought of when I made it. Personally I don't have strong views about the bearings and seals. Yes defo adjustable taper bearings are the best and most professional but for my occasional use the deep groove ball car wheel bearings I used (which I had already) seem to be fine. If I had to buy bearings then I guess I would have gone for taper. So again it prompts the question "what for and how often?". I think the live centre idea is good if you have one large enough - I wish I'd thought of that 😁 Cheers
@@HaxbyShed Thanks for answering. I still dont know if you have a 4"chuck or not. This is what I would like to do: First my lathe is medium size with 170cm swing and 1meter between centers. If I use a 4"chuck in the tail stock I have got to use a MK4 14mmx1 threaded live center. Now if I want a 5"chuck or 125mm instead, no problem but now I have an 1/2"thread diameter for connection. If you get a Myford or Boxford 5"chuck you get twice the diameter with 1-1/8x12 and the other is 1"by something. This is what I want! Nobody makes it in MT4 which is my tail stock size only MT2. My question: make and adaptor from 14mm inside to 1-1/2"outside put it on the MT4/14mm live center and tig weld it on carefully at both ends from max strength and rigidity. Tell me what you think. I really enjoy your videos. Bernard in Brittany.
Hi Bernard, truthfully it is a bit difficult for me to advise you on the detail but I can confirm my tailstock chuck is 5 inch / 125mm. The only thing I would say about the 5in chuck is that it's quite heavy and can cause the tailstock to tip forward when the tailstock is unclamped and the quill extended. I have a 4in pipe centre already so a 5in chuck increases my capability for larger cylinders/pipes, as well as smaller diameters. Cheers
@@HaxbyShed Thanks. I am still wondering why the Mt4 has a 14mmx1 thread while the MK2 has a 1-1/8"thread. Does not make sense. Cant find a MT4 revolving center with 1-1/2"thread.I am not worried about the tailstock tipping over it has two clamps spread apart clamping on the bed rails I. Will make my own adaptor and use a 5"'. Some people use a six ich wood chuc cause it is lighter, but I would not trust the jaws.My lathe has a 170mm swing might as well go bigger.
How stable is it in use? I watched Kurtis in Australia build one, (his lathe is 26 feet long on the bed), but you beat me to it. Have a 14 x 42 Acer geared lathe from 1999 with #3 Morse tail. What made you choose the wheel brg. instead of 2 angular ball brgs. or 2 tapered roller brgs.? Was the 5 inch too large? Lots of questions, I know, but if I build one I can't afford to do it twice. Nice job on the building of the tailstock chuck. I went back & watched it twice. Cheers.
Hi Robert, thanks again for your comments. Just now I watched Cutting Edge Engineering Australia Oct 2020 doing the 4jaw tailstock mount - never seen that before. I actually got the idea from a UK channel called 'David Wilks'. He does a lot of heavy trepanning but in one vid he had a heavy lump between two 4jaws. Here is an example of his vids th-cam.com/video/5fjofVlOHac/w-d-xo.html Like Kurtis I just used what I had - and I figured a car wheel bearing holds a car wheel on so it should do for this. It is surprisingly stable, I put up a video measuring runout and wobble - HS55. Now I'm not saying you could run it forever in an industrial machine shop but for me it's fine. When I have it apart next I might add a screw and retaining disc on the chuck end of the MT3 stub shaft to clamp the bearing end-on but for the moment the press fit is holding good. I thought a lot about 4in or 5in chuck. But I have a 4in pipe centre already and I've just finished a vid on machining a thread on a 4in rough pipe and I was glad of the 5in chuck (that vid will be out in about 3 weeks). The only downside of the 5in chuck is it's quite heavy and is a bit too eager to tip the tailstock forward. I've recently drilled 24 indexing holes around the backplate - that's another vid coming. Cheers
Hi bootsowen, you are right of course that I did not need to do it for a job or specific project but I think building my skills and experience is a worthwhile investment and enjoyable for me, and shared for others to watch if they wish. It was the first time I had used my tailstock 4jaw and the first time I had used the fixed steady. Usually when I try something new it takes me a few goes to learn the limitations of my machines and indeed my own limitations. I guarantee sooner or later something will come through the door that needs that capability .... and it's more likely now that I will get it right. But maybe I'm giving you a serious come-back when you were just teasing me really ;-) Cheers
I wouldnt do any work for Boris, I would expect the job you take on would change every few days and end up nothing like he initially said it would. I would also prefer to work for customers who pay rather than just promise.

Thank you for taking us through the process; I don't know when I'll have a chance to use this skill but I'm glad I have it.
Hi Jim, it just goes into the knowledge bank to be called on sometime ...... I think time invested like that is never wasted. Cheers
Nice work ! Good luck with Boris’ pipe
Hi Sanjay, I made that before the mini-scandal about who paid for his flat refurbishment ...... I'm not riding on that :-)
@@HaxbyShed 😂
The only scary part the ph call from Boris. Im sad you was subjected to that severe kind of buffoonery. I wish you get well soon.
Hi PJLee, yes it's often a mistake to make witty comments about politicians in the vids - when I made that light hearted joke we could not have imagined what was to come ...... Thanks for watching.
Hello,
Your tailstock chuck looks very good.... Good to see Boris has your number too...
Take care.
Paul,,
Yes, and now I have his number I can lobby for tax relief on Worksop upgrades and I'm sure he will get Rishi to fix it .... (For non-UK folks, there is a bit of a lobbying scandal at the moment)
It looks like you have been inspired by Kurtis in Australia

Nice Job Haxby old chap. That 500x70 job must be a bung to stop the lies coming out of Boris's mouth:)

Bert Munro used well seasoned second hand cast iron underground water pipes to make the sleeves for the cylinders on his Indian!
Hi Matthew, yes an amazing guy and a great story. I saw the film with Anthony Hopkins.
How about making some cast iron rings for "Your hydraulic cylinder", there's still plenty of them in use.
Great set-up, hope it doesn't rain.

Hi, boring the inside end on, now there's an idea - one for the future maybe. Cheers.

Nice work.
Hi Ozyrob2, thanks. It was fun to do.
might need a honing maching if your moving into cylinder repair.
Hi Geoffrey ...... boring and honing .... perhaps something in that idea ..... :-)
I think one day You gonna turn it into a connon...
