Hi, You might be interested. Your lathe is a so called "patronendrehbank" made by de firm Kröner und Reimer Leipzig Lindenau. She is modified. The ballbearing in the back is not original. Originally the spindel can move lenghtwise in smooth bearings. This movement was possible by a so called star wheel and threaded bushes with different threads ( patronen auf deutsch). All of this so you could cut screw threads on this lathe. I think I saw some parts of the mechanism in the original video but it looks like You did not use it in the restoration. I myself got 2 of these lathes ( all be it incomplete) and found a picture of this late in: " Paul Schlichting Die Feinmmechanik" . Congrats, nice work. Jan

Nothing about Kroner and Reimer on lathes.co.uk so there's a noble job for you :) Looks a lot like the old Karger lathe I'm fixing up.

To cut threads on a lathe, there needs to be a lengthwise drive-screw for the cross-slide. The cross-slide drive and the main spindle are geared together, so that as the chuck turns the cross-slide advances, to create a thread. What you described (the spindle with the chuck moving backwards and forwards) sounds more like a "rose lathe" or "rose engine", used to create guilloche patterns and uses those "star wheels" to control the movement of the main spindle.

+Rolingmetal - That was a great video. Very interesting.

"Hello friends" is my favourite part of your channel.

Love seeing an old machine like that come back to life.

Found this channel when this project was started, kinda nice to see it completed :)

the pair of intermediate pulleys is called a "jack shaft" and they are often used in power transmission to attain precise ratios, or in cases where side load is not desirable and face mounting is impractical.

That lathe is nothing short of a piece of Art - stunning restoration

Very good work on the restoration. Well done. Looks to be in very good shape now. I can appreciate you are glad the restoration work is behind you and the lathe finally up and running. I did some cleaning of a Southbend Heavy 10 back in 2014. A lot of work, but your restoration was even more work. The lathe may have been designed for line shaft drive, the picture you showed with the large overhead flat belt pulleys. Originally the line shaft may have been driven by a water wheel, later a steam engine. I would refer to your present drive system as using an intermediate drive shaft. Very common for old lathes which were designed for line shaft drive which was much slower speed than an electric motor. Your tool post design needs shims to get the tool at centre height. Consider getting feeler gauge sets at a flea market and take them apart to provide a lot of shims of different thickness. Not good that the pulley is causing vibration. This could impact the finish on the machined parts. You would need another metal lathe to try and fix the imbalance, unless you can add weights similar to car wheel weights. Dave.

I've become addicted to watching your videos I found this channel 3 days ago and I think I've watched like 20 videos already

Great restoration and a testimony to its build quality and also former owners, that it still, despite the vibration, runs so well. The chuck came up particularly well I thought and the whole seems a very useful machine still. Well done!

Very cool and well done. It's really nice to see you bringing back these old pieces from the boneyard. Thanks. Keep up the great work and videos

That's a really nice lathe you have! I love old equipment for it's ruggedness and style.

Nice lathe restoration. I did up an old Schaublin 102 toolmakers lathe in way worse condition and it also came up a treat. Those old lathes certainly have style. Plus they are nice to use, quiet etc. Cheers Rob

That was a wonderful old lathe with signs of many years of hard work! Now, due to you great restoration, it will have new life as an excellent machine again! I’m sure the lathe is overjoyed and excited to get to work with some humans again!

Nice job restoring it and getting it running.

I remember back when you go this... it was one of the events that made me go out and get an old lathe of my own. It's good to see if working, I thought you might have hit some kind of disastrous "wall"... and that's why we heard no more.

You gave a new life to old beauty. Thanks for her and your post.

You Sir are a BAD ASS!!! Fantastic Job!! You should be very proud of the work you do... I'm almost at a loss for words... Excellent!!

Wow, you are doing a fantastic job with that lathe - congratulations, it looks terrific. It most certainly will be the first time that lathe has seen a carbide insert, lol, or an aluminium bar for that matter. Lol, well done.

I am restoring a Seneca lathe at the moment almost the same age - great job on your arduous clean and build. I am considering mounting a 3 phase motor and VFD also for speed control and improved safety, but am still considering the belt slip with the original design that reduces the shock load to the chuck and headstock bearings. If anyone else more familiar with this aspect has experience please leave a comment :)

Post is really back for good now😁, great content as alwayd

Nice restoration, and video capturing it. The lathe looks great.

finally at last! my beard grew waiting that video.... i almost travelled to germany to help you man!

The intermediate shaft between the motor and the spindle is known in the UK as a "layshaft". The overhead drive and belt system is known as a "lineshaft".

just in time :) I bought the same kind of belt driven german lathe (Kärger) a couple weeks ago. Will try to restore it this spring

The mounting system that supports the layshaft and lineshaft is known as a plummer block.

Very nice. The before and after photos represent a lot of work.

MAN! That thing looks gorgeous !!!!

Nice restoration, you did a wonderful job! I just finished restoring a 1903 Stark flat belt lathe, it was in about the same condition. I'm a retired toolmaker, from California, hope to chat someday!

Nice Job. Have wanted a lathe for many years... might happen sometime. Citric Acid for rust removal works Great! I always keep a stock of citric acid in the shop.

Beautiful restoration!

Nice lathe restoration. Yep, this thing are a work of art ....

wow that "needle scaler" was something I had never heard of. I just looked it up and its a great tool!!!

To get a nice true thread, it might be a good idea to lead the tap into the work-piece whilst holding it flush, against the headstock; then feed by rotating the chuck.

I'm excited for the upcoming welder! Cheers

very nicely done and great find!

Awsome video, A excellent restoration of a Classic machine! Very very good, congratulations!

Great videos. May I suggest Soda Blasting for cleaning off that paint, leaving behind a water soluble media. I use a gun with the little media tank on top or you could use almost any kind of blasting system.

English words for that intermediate shaft are Jackshaft or Countershaft. The difference is which direction the shaft rotates. Automotive transmissions use gear driven countershafts that reverse rotation to transmit movement. What you used is most likely a jackshaft as it rotates in the same direction as the motor and the chuck. I just looked it up.

it's a "transmission drive" from previous other references . was probably done in the late forties. i offer this because i have seen this type of setup/modification several times and they were claimed to have been done around that time frame. folks used what was at hand to get things done and this type of drive was tried and true at the time. of note i have seen similar setups that used small gasoline engines. very sketchy! i enjoyed seeing it brought back to life.

No, it's a jackshaft-used to subdivide rpm from motor and increase torque.

It's a beauty!!! Great job and video. Thanks.

Looks Great. I agree, those belts have got to go. I'm looking forward to your upgrades.

Great video, very much enjoyed it, thank you for showing. As you mentioned adding a VFD for the motor, I was wondering how you would size it (wattage or full load current). I have a similiar old lathe, it too was converted from overhead drive to direct motor drive. The motor mounted is a Brown Boveri 1.3kW. However, that might just have been any motor they had available and might be oversized, or not. So, for selecting a VFD I was wondering how much headroom to give for lathe operation, ie 2.2kW or 3kW. I will need to run it on single phase 230V and wire the motor for 230V 3-phase (Dreiecksschaltung). And therefore was wondering, what motor you have and how big a VFD you would pick..

Great work! I love this!!

Your restoration turned out well 😉

Beautiful job

Congratulations what a wonderful work thank you for posted.

Congratulations on the restaration of your lathe. Looks fine. Have a lot of fun with it. (Gratuliere! Viel Spaß damit, sieht ausgezeignet aus.)

You should also build a cover over the pulleys to keep things from getting caught. Thin sheet metal or expanded steel would work just fine.

The intermediate pulley assembly between the motor and headstock is called a jack shaft.

Purrs like a kitten, great job. That's a lot of work !

Looks like it came out great. Bit of fine tuning and it should make reasonably round things!

A needle scaler is great for slag cleanup after stick welding. Great video! Take Care and be safe, John PS, you know, I guess that belt drive setup could be called dangerous but I don't think it is any more dangerous than the inherent 'danger' of operating a lathe. In other words, if the belt drive is too dangerous for the operator, then they shouldn't be using a lathe in the first place.

Amazingly talented guy love your work keep going on and keep doing what you love to do

What's the deepest cut you can take on steel with belts with this ? Great resoration

Very nice restoration!

The envy in me is big. Great vid bro!

Super Video, eine echt klasse Drehbank! :-)

We call it a thing! I would enjoy videos of you modernizing the drive of the lathe and adding some functions not available in its current state

Great restoration.tell us what is "accuracy" of this lathe?Good,bad or acceptable.

Looks great!

Good cinematography and narration. Mechanic soap, oil eater aka simply orange, etc, are good degreasers.

gut gemacht ! hab eine Weile drauf gewartet . wunderhübsche Maschine

Top job young sir.

Nice job all round.👍

i do like to the video before i even see it you have great project bro =) respect

Two questions: Did you test the paint for lead content? Why did you not use paint stripper instead of abrasion methods?

nice work!

Great job!!!

TPAI, what you think about removing rust with a phosphatizing agent? I tried the gel citric acid one with little success.

7:50 I would call this the Primary Belt Drive or Live Drive (motor to Intermediate shaft) my English is not good, but I did work at the Poreba Machine Tool Factory in Poland about 10 or 11 years ago.

muito legal seus videos parabéns

FINALLLY, I watched those videos when they came out lol

Envy you for that lathe mate. It represents an era and it's good enough in many applications. Do you know what year was it made and who was the manufacturer?

Is it just me or does the chuck move backwards when you are drilling? Maybe a bearing is worn and allows movement away from the tail stock? Brilliant job. Love old tools being resurrected.

Better lathe than never

I don't know if there is a specific English name for that intermediary pulley shaft, I think I would just refer to it using the generic name "jackshaft"

Counter shaft is used for gear transmissions because the rotation is reversed. Intermediate shaft is the term when pulleys/chains/belts are used because they do not reverse the rotation.

'jack' mayb more technically correct but if you search ebay for lathe parts you find nothing for jack shaft and everyone refers to the shaft in question as a counter shaft www.ebay.co.uk/sch/i.html?_from=R40&_sacat=0&_nkw=lathe+countershaft&_blrs=spell_check

It's beautiful.

i am curious to hear your thoughts on the best way to protect steel from rusting in salty environments. i am torn between cold bluing and or then oxide etching primer and then a 2pac paint?? danke im voraus

In Eglish, we call this overhead belt power supply was known as 'lineshafting'. Great video.

Hi, thanks for the video, any idea where to find and buy those covers of the oiling holes on each side of the headstock?

Beautiful.

Well done.

Very nice!

Wow it was great to see it brought together :) I've wondered when that'll be the project of the day :) I know it's not really your thing but I'd love to see how you'd approach making a 12v dc oven as I'm living off grid with low income so either fix it modify it or build it :) not a fan of new lol Andy

Parabéns ! Muito bom .

Witam z Polski to są piękne z duszą maszyny panewkowe ciche precyzyjne w toczeniu wiadomo trzeba dbać smarując panewki rewelacja kocham takie klimaty , wkładając serce w remont taka maszyna odpłaci uciechą pozdrawiam dziękuję za wspaniały film

Brilliant!

I've always called the left side where the variable pulleys connect to the chuck The HEADSTOCK. The opposite is the tail stock....

If the Jacobs Chuck is only held in the tailstock by the friction of the Morse taper, you should hold the chuck when reversing out of the hole you drilled. The last thing you need is a chuck (and drill) being flung at speed randomly across the garage, possibly in your direction.

I'd call that bit with the belts and pulleys on a transmission, as it's transmitting the power from the motor through itself (and looks like you can "change gear" too with it) to the lathe, probably a proper English word for it, but I don't know what it might be... :)

The part is called a jackshaft in English. Nice lathe!

I don't think English as specific term for the motor setup however we would refer to the shaft and pulley assembly driven by the electric motor as the countershaft assembly, which is always paired to a matching "driveshaft/transmission" or in this case the spindle. Little late on the feedback ... but who knows.

The assembly in English is called a counter shaft. The counter shaft assembly actually looks very good and is standard on lathes 50 years newer. The only thing I would change is rounding corners of the flat plate just to blend their style in with the other curvy/cast parts. Looks like a great vintage lathe. Your lathe was a Treadle or foot power lathe in the beginning I bet. In the end there is little consideration for antique value. It's mostly about functionality. Put a quick change tool post on it and don't look back.

It's alive!

I wish I could like this twice!

Wirklich eine Gute Restauration ... :D Freue mich schon dich beim Drehen zu sehen.... :D

I've always heard intermediary pullies called "Jackshafts"

How do I prevent flash rust after degreasing the parts before painting?

Gibt es eigentlich eine Kombination aus Drehmaschine und Schweißgerät? Also um z. B. zwei Rohre zusammen zu schweißen.

What do I know?, but it would seem to me that retaining the belt drive system would be wise versus changing to direct drive. Consider the lathe crash situation, the belts would slip and the machine might not be damaged as much vs a direct drive configuration.
