Hi Max, the old JMFT is measuring up and shaping up quite nicely. Those are some pretty good numbers on the test sample. Thanks for the detail and explanations enjoyed thoroughly. 👍👍👍 Cheers….
As always, excellent video. Many thanks for pointing out the groove on the 'live' centre and also setting up the new chuck. Grooves on the bolts and marks between the 'V's. Super for a new 'bozo' like me! I learn sooo much! Some things are (to me ) very subtle, like the little nicks on a left hand threaded nut. Thanks again, Col.
Hi Max, nothing wrong with that lathe, our machinist used to check our lathes, less than 7/10 of a thou over 10" length on a 2" Dia test cut was considered in spec. Now I know the difference between a live centre and a revolving centre. I had a Bison Chuck on my DSG and have one on my dividing head, durable chucks. Broke a pinion on the Bison Chuck while setting up a long shaft on the DSG, left the Chuck key in, low speed crunch. Had a new pinion few days later, guess that's why you pay the big bucks for parts availability.
I have a Bison on my indexing head but no reverse jaws for it . I might change it to a cheap & cheerful and set it up as an adjust true . The wear on that lathe , i can live with no worries . Operated far worse than that ! Cheers 👍
Thanks Max. In particular, I really liked your run down as chuck purchase and why. Sort of a forecast of where the future might be as precision? You see Max, I'm planning to be in my shop more as better weather has arrived. Mostly smaller projects that have been on the bench waiting. I find your video's very clear with excellent volumes and look for best process. Regards from Washington state, US McGary
I had to do a double take on the Dial Indicator resolution when measuring spindle droop, certainly no measurable slack in the bearings. Perfect "Test Bar" size and geometry, hollow bar to reduce any sag, no chuck jaw bell mouthing. JFMT lathe is in good nick geometry wise, seemed to give better diameter results in metric. LOL. Thanks for sharing Max.
@@swanvalleymachineshop Yep there’s a heap of them out & about today out in Beechboro, including 1 stimpsons carpet python, & a handful of juvenile tiger snakes. Steve Watkins channel is building a kingsway tool in the last 2 videos if that’s any interest?
My favorite 3 jaw chucks are Bison, Buck and the top of the line Rolm, all in forged steel. When I bought my new Buck 8” Adjust-Tru three years ago, I was pretty happy. Yes, it’s expensive, but I have it concentric to 0.0002”. That’s not that hard to do. I use a 1” x 6” pin concentric to 0.00005” to adjust it. But I have just a 14” lathe, with a D-13. I couldn’t get a back for the 8” model from Rolm for their best line, which uses a weird mechanism instead of a scroll, so I bought my second choice. But it held up very well and really is more accurate than the Hardinge high precision 5-C collets I have, which are 0.0005”, and is as good as you can get for 5-C. This chuck is rated for 4500 rpm, which is pretty high.
Hi Max, lots going on here. I can watch and talk chasing precision all day! I had no idea about the correct use of “Live Center”. Glad to know the correct words!
I guess over time a lot of terminology has changed . I think there are quite a few differences in terminology for the same thing from the United States versions to British versions & early years to current times . You may have noticed that one ! Cheers 👍
@@swanvalleymachineshop The American use of "Live Centre" instead of the correct 'Revolving Centre' has been annoying me for years. So glad to see you explaining the correct terminology. Greetings from Scotland.
It's amazing how language drifts and changes over time - too often through misuse of words. I was taught at school to always use the correct terminology or "be known as a fraud!" So I'm glad to learn this one.
I'll fess up that the tool post came out much better than adding detente locations would have. I really can appreciate that it locates in smaller increments. Good job Max.
Looks like the JFMT will be a pretty good machine. Those chinesium chucks always make me think of the chuck stephan gotteswinter got, and it was full of grinding dust or casting sand. Probably should open that one up and check it before too long.
My go to chuck has been the Bisons, made in Poland. They are a lot better than I am. The ones I get are not simi-steel (cast iron), but rather forged steel and they can do relatively high RPM. Cheers on the new chuck and bummer about the crappy distributers.
Great video max no doubt about it you’ve got a good lathe there had to laugh when you was undoing the wrong screw on that chuck I thought it’s not just me then lol cheers max👍👍👍
Hi Max good video , glad to see the shops coming along . i got to ask do you know how Matt (Matty's workshop) is doing he hasn't posted any videos lately hope you may have heard something . Thanks Steve
Many measurements taken. Many variations on toolpost possible. But incremental was the desire. Nice to have new quick 3 jaw. A tool purchase that lives up to expectations. Better than " pissing in the wind". I dont like blind mans bluff either. Using aluminium for bench lathe levelling.
Great CSI-ing Max. But could the differences in the diameters be the material itself. Being that it is a soft type material and being different in the centre as to cutting more/ less from that???
I don't know a good chuck from a pinecone, but I've heard Bison chucks are ok. And as I'm sure you know Poland makes some good chucks I've heard, but I couldn't tell you the brand names. Just looked on Google and it said Bison chucks are made in Poland by some manufacturer that is the largest in Poland making such products. I think Bison is a trade name and or the company name is Bison - Bial or something. So it looks like you have to let the lathe settle for a week or 2 after the initial leveling and then fine tune it. That makes sense being it is a large piece of metal. After a couple weeks of temperature cycles it settles in I guess. I wonder if they stress relieve the chassis or if it is necessary for cast iron in that application. I'm assuming it's mostly cast iron. Anyways, good video Max, you look like your doing well. And as always I learn something watching your vids. Thanks for the continued hard work and the lessons. Cheers mate. E
Bison make a really good lathe chucks . I have a small one on my indexing head . Super expensive over here ! Back many years ago , some of the English lathe manufacturers like Dean Smith & Grace left the bed castings outside for quite a long time before they were machined for stress relieving reasons . 👍
@@swanvalleymachineshop Back in the old side valve Ford V8 days they would cast the blocks then leave them out in all weathers for 2 or 3 years to cure the cast iron before machining them I have been told.
The only time noticeable chatter came in was turning 350mm away from the chuck with no tailstock support . Still , it is something you have to be careful off . 👍
Yes , that particular inside way would need grinding . The rest of the ways are good . At this stage it is not enough to worry about for this size machine . 👍
Good evening, do you know how to align the headstock on the Weipert W500 lathe? I am unsure where the screws that allow the headstock to pivot are located. Is it possible that on this older lathe model, such an adjustment is not available?
@@swanvalleymachineshop cool thanks max. I have a couple of small lathes that I’m slowly cleaning up and learning so much from watching what you do and how you do it. Yes they came from the same country as your new chuck. Thanks from kiwi land. Looking forward to the next one.
Hi Max, I would be delighted if my lathe would cut to within 0.01/0.02 mm over 400mm. Looks like you have got a beaut there. I use a Rohm centre, they are the dogs bollocks. I watched a video of Keith Rucker the other day and he was turning some brake drums. His chuck face was running 0.03" out. WTF?. anyhoo, Best wishes, Mal.
Lol , good old KR , all the gear but no idea ! He had that chuck set up on a face plate & he should have corrected the problem properly by reworking the taper . Not just machine a bit off the face & stick the shim back in ! Cheers 👍
I just don't believe those measurments on the spindle face and nose using the 50 millionths" indicator. It didn't move at all, even though there were obvious marks on the surfaces.
Bugger me mate you only do tractor parts (LOL) does it even mater , I'm an agri boddger , if goes on and doesn't rattle it all good . if it does rattle so what they will NEVER grease it any way .
One thing to consider if turning without coolant is that the part starts off cold and warms up as the cut is taken, if then wait for it to cool down there will be a difference in diameter, even if small, and of course the difference will change if you take the cut in a different direction.
A cut in the other direction will only make a difference if there is any carriage / bed wear wear & i know there is wear on the inner way . This was showing a mirror image from one end to the other with the direction change . If the part grew with heat in the middle , it should measure undersize when cool . When cool , it still measured 1/2 a thou large . It is not a temp issue . Just cutting off some larger solid round bar to try again with the new centre , just interested to see if anything changes . Cheers 👍
A small amount of tool height change will not change the diameter that much but wear in the bed causing a cross shift in the carriage position will have a great effect .👍
Max should be Mad Max The amount that is out could be from a Number of different tooling to centre wobble Come on mate the amount the LATHE IS OUT For general work as you say is NOTHING Your looking for PROBLEMS go that route with any machine would be more than ACCURATE Stop looking for problems Cheers from N Q AUSTRALIA
Lol , i have too look for all of it's inconsistencies so i know how the thing can perform & what to expect . Easier to know what i am dealing with now and so far it is not that bad . 👍
the word on the street is that Max is considering 'Elocution Lessons' - to speak clearly and educated ................ I think 'we' like your current style of rough and boozy 🏴☠

No , i would not expect so as it is a good grade of steel . 👍
Max you said that material was not heat treated so there could be some inconsistency in the material !

Can not say i have . 👍
half thou over 300 mm, thats very good max !
cheers

Thanks 👍
What size Taylor Max? I know of an 8 1/2 inch for not a lot of money. Got a load of jaws with it too.
Thanks . 10 inch . I just looked at your email . 👍
If it was for me, I would say "good enough".
Sounds good to me Rusty ! Cheers 👍
Could also be harmonics over the length, as in like string harmonics, chattering shows a bit of the results in worst case.
The only time noticeable chatter came in was turning 350mm away from the chuck with no tailstock support . Still , it is something you have to be careful off . 👍
You will grind the jaws of the new chuck…right?😮
Lol , year right !!! I want to see how long it will last first ! 👍

Thorough!! Always enjoy the education . Thanks Maxi!
No worries 👍

Thanks 👍👍👍
was the point your trying to make if it high it is still parallel to the rotational center. while the twist will not be? I dont know machinist lingo.
A small amount of tool height change will not change the diameter that much but wear in the bed causing a cross shift in the carriage position will have a great effect .👍
Max should be
Mad Max
The amount that is out could be from a Number of different tooling to centre wobble
