It's certainly no "Shit Show" you had me chuckling right through. That surely is an unusual threading method and I've only seen it on your videos. Great stuff. Thanks

[@douglasthompson2740]

PS: Enjoy your narration also your straight ahead tenacity with the carbide creating an interrupted cut at maximum low speed! The carbide gods are rolling in the aisle. They smack you down and you come right back at them, again, and again!! Keep the videos coming. Interesting too as I have never seen that style of thread cutting.

[@chunkitlau4553]

Thanks for sharing this experience, the threading mechanism is very similar to my mini Unimat lathe. I think the spindle bearings are worn, you can see the wobble in the workpiece when turning it by hand. Thanks for sharing!

[@DavoShed]

As you turn the chuck by hand it’s stop start stop start. Carbide tips hate this and can chip every time the tip stops mid cut. You need to buy or make a huge tap wrench. You could cut 80% on the machine and tap the rest. You would still need a way to hold the part. I have a gadget here called Super Jaws. It’s basically a floor standing vice made for wood work but hey it can hold steel too. It opens up to probably 400 to 500 mm. I’m sure you could find a cheaper knock off if you wanted. Congratulations you got there in the end. Very Entertaining :)

[@Rolingmetal]

3 cheap ass inserts won't break the bank :) If you loose the spindle midway in to the cut they very easily break.

[@DavoShed]

Rolingmetal Strive for perfection and be happy with the result you get. But keep striving :). Next time only smash 2 cheap arse inserts :)

[@MegaLostOne]

Wow, I was complaining because I was cutting metric thread on an imperial lathe and no reverse on the motor so I was having to run it back by hand. This video made me feel like I had it made. I have since installed a reversing switch on mine so I don't have to reverse it by hand (just yesterday). Makes me think of the old saying "I was complaining because I had no shoes, then I met a man with no feet." I had to fight my lathe when I got it, the gibs where so bad that any attempt at threading or parting off led to the tool digging into the work and binding the lathe up, but like others have said I believe the chatter on yours is from bearing wear/looseness. Plus any threading using that design is going to allow flex as the chuck/shaft move away from the bearing as well. Great video, goes to show that with some determination a person can still get the job done.

[@MegaLostOne]

My current projects are restoring an old Craftsman power hacksaw that I picked up for $70 and a Drill press that was in need of a lot of attention that I got for $15. Hard to make projects when the equipment is a project in itself LOL.

[@johnfry9010]

You can actually see the spindle and backplate move up and down when you turn the spindle , might be some bearing work is needed ?

[@thecorbies]

Haha. I came here to say the exact same thing, but you beat me to it. The spindle upward motion is clearly visible at 11:23 & 13:47 So, like you say John, defo some head bearing work required there. Regards Mark in the UK

[@crazyfeller5704]

In the first 3 minutes I came to the conclusion something is loose. Chatter is different than a rumble.

[@Preso58]

Yes, I caught that too....

[@MegaLostOne]

I could see the play from the bearing/shaft as well. I didn't look close enough to tell if they where Babbitt bearing or a bushing. If they are Babbitt then he will need to re-pour/shim and run them in. This design for threading will always cause an issue regardless of the bearings since as the chuck moves away from the bearing it is allowing flex in the shaft.

[@Rolingmetal]

Maybe, but I'm not completely convinced. That might be flex what you see in the video. Have a look at this video kzbin.info/www/bejne/h3S8qmSZna16bpo

That's very interesting, I've never seen a threading operation done on a lathe like that!

[@Rolingmetal]

It's how I operate it, no idea how it was done back in the day :)

[@lv_woodturner3899]

Glad you were able to get the thread working. I have made my share of single point threads for wood lathes, 1in x 8 tpi and 1 1/4in x 8 tpi. I also have the taps. I agree it is not practical to use the tap alone. I do like you did, and use it to clean up the single pointed thread at the end. Still takes a LOT of effort to remove even a couple of thou. 8 tpi thread depth means a lot of surface for the cutter. I use light passes e.g., 5thou or less to reduce the risk of the insert breaking. Still some insert tips can break. Picking up an internal thread is not easy. Good job. Dave.

[@Rolingmetal]

I noticed that a lot of wood lathes use a 1 inch 8 tpi spindle nose. Interesting :)

I prefer the old one over my newer Chinesium lathe.

[@ToreDL87]

Ok now I'm starting to see a trend. I looked at cutting tool rake angle and contrary to the first vid I saw (where I left a lengthy comment) you've learned quickly (as expected) and the cutting tool looks to have a nice positive rake and is well-centered to the workpiece. But look at that workpiece and chuck at 14:00, it's got massive run-out with just hand-spinning it!

[@Rolingmetal]

That massive run-out out is partially explained by the flex in the spindle when it moves forward. Have a look at this video: kzbin.info/www/bejne/m5jEZoKIjaqtfsk

[@miro6138]

13:45 if you have this much play in your spindle bearings, it's no surprise that it chatters like crazy. I suggest you to measure the play, and try to adjust it. You said that you suspect, that the motor mount causes this chatter - that is just physically impossible.

[@Rolingmetal]

Maybe, but I'm not completely convinced. Have a look at this video kzbin.info/www/bejne/h3S8qmSZna16bpo

[@miro6138]

@@Rolingmetal I've seen it when you posted it. That radial play measurement wasn't done properly - you need to use force (as to simulate cutting forces). For this size lathe, I'd recommend to chuck up at least 300mm long bar, and to exert force arround 50N on the end of the bar, while measuring the spindle movement. This needs to be done in horizontal and also vertical plane - there should be more wear in vertical plane of the bearing. It wouldn't be very complicated to make new bearings - even with your chinese lathe. Than a bit of scraping, and your lathe will be as good as new.

[@EverettsWorkshop]

Man, that would require more patience than I have, but it's not a bad idea to have started the thread using the lathe and then finishing it off with the tap, nothing wrong with doing it that way. You then know your thread form is correct.

Try HSS tools instead of carbide. Less prone to chipping and works better at low speed.

[@Rolingmetal]

But also not indexable and easy to replace.

[@stevenconnor4221]

@@Rolingmetal the man is correct Im an engineer by trade. You could even braze a carbide insert into a specific tool. The chipping of your insert was probable caused by the intermitent loading caused by chuck running out and to deep a cut.

[@brucematthews6417]

I suspect that the threading pointy bits are snapping off like that due to even just stopping. You might not be turning back but simply stopping means the pressure is shifting away from the proper direction and changes to a straight inwards force that chips away the carbide like a flint worker knaps away flakes of flint just with pressure. For what you're doing with hand turning to thread on the nice old lathe I strongly feel that you would be much better off with HSS tool bits. To deal with the boring bar chatter you might want to give a try to using an old two flute end mill as the boring bar. The really high angle back rake might cut more cleanly without the same lifting force which is what is likely causing your chatter. Just angle it slightly so the side doesn't drag in the cut. I was in a pinch one day and tried using an old chipped end mill for this and found that it worked so well that now it's a regular tool I use a lot. And with the flex in the Karger's head shaft due to the fairly small size and likely some play in the head stock plain bearings anything that you do to reduce the load of a cut is going to pay back as reduced or avoided chatter.

[@Rolingmetal]

You're right the point snaps mostly of when you stop the spindle during the cut.

[@Rich-on6fe]

I'm guessing carbide tips don't like on-off 'workout' tapping any more than they like interrupted cuts or being dragged backwards over the work.

[@Rolingmetal]

You are right about that.

Looks like the spindle bearings are shot on that lathe. At 13:56 you can watch the workpiece & chuck lift each time you rotate the spindle. If they are made from babott, maybe you could pour new ones?

The bearings might be the issue but the motor mounted to the bench might also play a roll. The bearings are cast iron b.t.w. Have a look at this raw unedited testing video I uploaded to my second channel. kzbin.info/www/bejne/m5jEZoKIjaqtfsk

[@HanstheTraffer]

Try tipping your internal turning tools forward about 2 degrees. That will give them more negative rake. I have a chinesium boring bar that I just bent a little until it stopped chattering.

[@Rolingmetal]

Interesting idea. But like the chinesium boring bars. Should not be to difficult to try next time.

[@johnstrange6799]

Can you get a ratcheting wrench the size of the nut behind the "threading die" so you can ratchet the spindle when threading instead of having to grab the pulleys? Not sure it would work, be any better, or any easier, but just a thought. It looks like you get a good grip and decent distance of rotation using the pulley, so never mind. :)

[@Rolingmetal]

I think you need at least a meter of leverage to turn that thing.

[@TH-im2bd]

Pretty interesting stuff... But I'm fairly sure that you are using the lathe in a way it's not meant to be used. That lathe doesn't seem to have conical bearings for heavy duty use, it's more like a vertical drill. That moving spindle is neat and useful but it can't handle heavy weights. Your chuck seems way too big to my eyes. Also, because the bearings are't conical, they can't be tightened when they wear. I would use a heavier lathe for normal turning and this one for more specific tasks like threading. Just my two cents but I'd go mad with all that chatter 😖

[@therealspixycat]

Recut the taper on the chuck and use the same angle to cut the taper on the backing plate?

[@therealspixycat]

@@Rolingmetal clock it and blue it to see how much contact there is

[@michelarneburg]

Maybe using a more viscous lubricant in these hydrodynamic bearings provides greater counterforce while cutting and accommodates an enlarged bearinggap. I guess good lubrication only works if your hydro actually is dynamic and maybe minimizing spindle forces by using sharper tools or working with the inertia of any parts can help keeping your machine under control.

[@Rolingmetal]

I actually though about using grease. In one of those grease pots you need to twist to inject a little grease. Have a look at this old video kzbin.info/www/bejne/h3S8qmSZna16bpo

[@michelarneburg]

@@Rolingmetal i was thinking about a thick liquid. Grease is rather plastic. I dont know if it is suited for this application. Some greases intentionally degrade by emitting oil and acting like a reservoir, like soked felt wich often appear in old machines.

[@Rolingmetal]

That's why I use a mixture of cv joint grease (has mos2) and oil. It runs slowly though the spindle. I lube it scarcely and run it for a couple of hours. I never had any heat issues in the bearings.

[@michelarneburg]

@@Rolingmetal At one workplace we used a thick wayoil, almost syrup like oil for punchingtools in tough materials like stainless steels and copper. We abused a small old lathe for sanding etc.. I often cleaned it and used a thin oil to enhance the flushing effect. Then i tried out the thick oil and the tailstock would glide off the back. It also made a great difference on vises.

[@wibblywobblyidiotvision]

@@Rolingmetal At several points in this video, there is visible movement of either the spindle relative to the tool, or perhaps the tool relative to the spindle. The latter might be an optical illusion due to the camera being mounted on the cross slide. Which it was, can be cleared up by mounting the camera on the lathe bed and repeating a similar cut (with a busted tip, because it's gonna bust the tool*). Otherwise, mount yourself a 50 cm or so bar of fairly hefty craptonium in the chuck, shove an indicator on the chuck body, and gronk on the end of the bar, see what your radial play is. If you can get more than a couple of hundredths of a millimetre, your journals need adjustment / re-scraping. Excessive radial play will automatically translate to vibration, a difficulty getting any sort of decent surface finish, and a lot of broken carbide. These are, I believe, symptoms you're seeing. * Carbide reacts really badly to the cut going static, you'd probably have got far better results - i.e. no tip breakages - with an HSS tool.

[@Rolingmetal]

I'll do the test you describe and post a little video about it. The camera was mostly on a tripod except for a few shots inside the bore form behind the lathe. HSS will probably also get damaged or dull and doesn't really index as easy as inserts.

I don't know about music, but maybe I should do a intro sound like Abom and the Keiths

[@evanangeletos964]

Your spindle rumbles because your head stock bearings are worn.

[@Rolingmetal]

Maybe, but I'm not completely convinced. Have a look at this video kzbin.info/www/bejne/h3S8qmSZna16bpo

[@vasyapupken]

this machine is too flimsy for carbide iserts. spindle is too thin, chuck is too heavy, it just bends.

Bump

First off, love the video I just subed. Second, there is something very wrong with your lathe bud. I would go bolt to bolt and make sure everything is tight. If that's all good, check the wear on your bearings. That "rumbling" is not normal at all. Best of luck, I look forward to your next video. I've been to the shit show many times, and this ain't it.

[@Rolingmetal]

Thanks, and welcome to my little shitshow :) There is definitely sometime wrong with the spindle. I'm thinking it might be the motor mounting and excessive play on the bearings. Have look at this little clip I uploaded on my second channel: kzbin.info/www/bejne/m5jEZoKIjaqtfsk Some unedited footage :)

Chater= usually go slower

[@Rolingmetal]

Unfortunately that doesn't help a whole lot on this lathe.

[@MF175mp]

Emco Compact 5 is super rigid compared to this

[@Rolingmetal]

I had a compact 8e as my first lathe :)

[@MF175mp]

@@Rolingmetal why did you sell a good lathe? Take compound off and bolt it to concrete and you have pretty solid machine

Scraptonium for the win!

[@gsxrjeff]

too slow a feed rate .2 per rev minimum,carbide screwthreading tips do not like cutting slowly ,they chip! lol its supposed to be funny

[@Rolingmetal]

I could speed up the video even more :)

[@stevenconnor4221]

Wtf .. how many inserts are you using.. stop. Grind a high speed steel internal threading boring bar. Btw you have lateral movement of your chuck, check bearings.

[@Rolingmetal]

I used up 3 insets and 9 points. Not counting the last one that survived :) HSS will mostly like also get dull and won't index as easy as carbide. I'm thinking what you see in video is flex and not play. But there might be something wrong with the bearings.

[@stevenconnor4221]

@@Rolingmetal mate i have used HSS on steel machining many times it just means you need to dress (light grinding of tooling to bring back its sharpness) your tool more often. Your inserts might be cheap causing failure or as said you have intermitent loading. Basically you should have easily produced thst thread with 1 insert face. Anyway i enjoyed your video just passing on info that may help you.

У тебя есть нормальный станок. Зачем ты пользуешься этой развалиной? этот станок просто ужасен! Лучше пользоваться Китайским станком, чем этим!

I prefer the old iron :)

[@ЖелезнаяЖизнь]

@@Rolingmetal Yes I love old iron too, but it needs to be repaired to serve you well
