Stefan you forgot to mention who showed you how to test Tail Stocks that way. I want you to teach what I taught you, but please give me credit when it is due. You did mention me in your scraping info that was almost word for word of how I explained it to you.
Yes! Sorry, forgot it this time - Absolutely right, that is where I learned it.
Egotist much?
@chris0tube Chris, With all due respect this was not a rebuild video, it was a technique used to test tail-stock height. to the head-stock. I have been using this technique for 50+ years and it works for a quick test. I also use it when showing new machine builders how to do it. I have the experience and credentials to recommend it. As another famous you tuber told me. There is always a person looking to complain.
@chris0tube I think you are incorrect and to the readers please overlook one complaint from an unknown person and appreciate proven facts and advice from proven Journeymen. There are different strokes for different folks. Stefan states he is using the test to check the height and side to side.
@chris0tube No use dude. He's determined that all his knowledge is better than the the evidence that you provide. Note how he attacks your credibility instead of refuting the argument, a sure sign of being unable to refute the point. It's sad to see someone get so full of themselves they are either incapable or unwilling to learn anymore.
Hi Stefan, thank you for taking the time to make videos for us. I enjoy them very much :)
great job Stefan , I love the way you worked on making sure you have the best coverage possible on the ways .. ENJOYED !!
I really love what you've done with this machine and all the other ones in your shop!
Hi Stefan. Your videos are very inspiring. You have a very workmanlike approach with no BS which is about as old school as you can get and most refreshing. I have had an Emco S11 since new and but have never come close to the kind of work you do. I am approaching the whole thing with renewed vigor since finding your channel.
this machine is still the most gorgeous little lathe on youtube, and so quiet!! i will never get tired of it turning so effortlessly
Thank you very much for your videos Stefan. It´s amazing to see how smart you are and how you use your gear. I saw you in This Old Tony videos and love to watch you too. Best regards und schöne Grüße ;)
Excellent tailstock maintenance, and modifications. Good tip on tailstock alignment, and bias to the front.
Good to hear "Aluminium" being pronounced correctly, your English is excellent, especially technical English.
Many thanks for sharing and best regards from the UK.
Well done Stefan, nice little tutorial, it is always nice to see how you go about a task and explain your methodology. Impressive tool post mount makes me envious! Cheers!
Looks like Emco had full Renzetti-Gotteswinter-treatment😁
Very nice job Stefan!
Very nice video! I just aquired a Super 11 which I learned on in 1990 when I was an apprentice. It was brand new at the time. After 30 years I was lucky to get it and an FB2 mill for $400. I have stripped the lathe to have resprayed as lived in a tough environment with the previous owner and hope to make more presentable. In a few months will go to strip and bring mill to my workshop. :)
You are very generous with your knowledge, thank you very much.
Love them lathe mods, Stefan😊. The work you do as always is exquisite. Thanks for the video
👍😁👍.
Good English Stefan....you make it easy to understand what you are saying. Thanks for all the tips.
I have this machine so for me this video was solid gold. Thanks!
Thanks for sharing, as usual, you do not disappoint. I always appreciate the fact that you offer a different perspective, an item of great value. Thank you Sir!
That EMCO is one of the cleanest lathe ever. That looks like a machine that I will like to own.
Thanks Stefan. That lathe is looking good. Definitely some great upgrades. Cant beat the full leather covers.
Thanks Steve!
That solid tool post is a thing of beauty.
Un gran trabajo y muy buenas ideas, tengo un EMCO SUPER 11 CD ( el de color rojo) iré realizando sus mejoras poco a poco, muchas gracias por compartir sus ideas.
Un saludo desde España!
I like the solid tool post. They really do increase the rigidity of the tooling. For the most part I have found that unless you are doing threading or controlling length of cut in the Z axis the compound is more of a hinderance than a help. The X axis cover greatly help with keeping chips and that away from the Glass Scale. Now all you need is a vertical slide and you have a minature Boring Mill
That's a very nice, clean looking Emco lathe you have there Stefan. Many great ideas that I may have to adopt and use on my own machine. Keep up the great work. Cheers, Aaron.
When I got my new (Emma's old) Multifix, I made a hold down bolt for it with a bit of "eye poker" on it to mount a camera. I never thought about indicators. Thanks for the tip!
Beautiful work Stefan. Thanks for sharing!
Awesome video
Love the upgraded lathe features
Just fantastic, I learn so much from your excellent presentations. 👍🔭🔬🎷🇦🇺
Thank you sir, a learning experience as skways.
Congrats Stefan! It's looking very nice.
btw.. I really liked the rack n pinion on your last lathe.. it made it more of a civilized tailstock.
What a great looking shop you have.
Stefan, thanks for the update on the lathe, great stuff as usual. Craig
The scale and read head layout is neat, and the soft covers and steel armour is a tidy setup. Well thought out👍👌🇦🇺
Great work on the solid tool post buddy! Very Nice!
Thank you Stefan, brilliant idea!
Beautiful work!
great video discussion / demonstration / build
I just made this solid tool post. Thank you, robrenz, and Kent VanderVelden for the inspiration. You guys are really incredible.
Hi! Are there drawings for the solid tool post 😀

Hi Stefan. Thanks for the tailstock alignment tip. It will be very usefull on my lathe.
Nice updates Stefan. I have the slightly smaller Maximat V10P and I will be adopting some of your ideas. Dean Bristow.
Nice additions.
Thanks for the video.
Bought a new tailstock and did all this last Friday. Took 5 hours (ground the tailstock base as well)
Thanks for showing the tailstock alignment, now I can see how far off my previous attempt was doing something else.
Thanks for detailing the tailstock alignment procedure. Certainly a lot easier than turning between centres and measuring both ends. That's always a tiresome and indirect method.
Cheers,
Mark Presling
Stefan, I found you by way of ToT and I must admit (sorry Tony) I enjoy your videos even more! You both do amazing and entertaining work, but there's something so enjoyable about your videos. Like a great man once said: "I love hard work, I could watch it all day".
I'm currently looking at a career change into precision machining - and you're partly to blame for that!
Thanks for the informative video Stefan.
Steve
Hey nice to see this update, Lance & Patrick.
Nice cross slide cover, wow leather now that is nice work Stefan. Also a nice tool post, time to build your own machinery? this could be enjoyable to watch.
Lance & Patrick.
Dangit you guys are pressuring me into my own solid tool post mount now!!
Nice looking set up !
Making a great little lathe fantastic! I wish we had a place in the US that would cut and bend like that....
Awesome!
Your lathe mods are coming along well . Cheers .
I am really interested in the double tool post arrangement. I am going to look into fabricating one for my Atlas 10F. Thanks for the idea!
Enjoyed that thank you. Gave me plenty of ideas for my lathe. Watch out for the eye poker!
EVERY MACHINE NEEDS AN EYE POKER! 🤣
Excellent!!!
Stefan you have a real nice second operation Lathe now veary nice work well done . 🙌
Still looking for a nice cnc lathe ;) Until then thats my main lathe ;)
I like your alignment tip !
That looks a trillion!👍
Nice work, i like the mods .
Literally no one:
Stefan: “Lets get this to one nanometer tolerance”
Hi Stefan, Great work, great vid and great explanation, TFS oh and great lathe. G :)
I chuck up a test indicator in the jaws and spin the tailstock bore to adjust it , just fast and simple for me. Im not sure if the id and od are concentric on the tailstock quill.
"...ancient grease. Not to be confused with ancient Greek." Although the two may sometimes smell the same.... Ta dum tish!
And they say Germans don't have humour..
What grease did you use on the tailstock, please?
@@BartolomeoPestalozzi444 That made me LOL!
Greek fire.
One thing you could do instead of the eye poker on top of the tool post: Make a tool-holder for the eye poker. This saves you a poked eye and makes it easier to get around the work while still allowing easy adding of an indicator. My indicator just lives on the toolholder/eyepoker thing so probably faster.
I went with this solution since I often have to get magnification close to the work on very small parts and getting a microscope in there while the eye poker is in is just a pain.
My thoughts exactly
Stefan, Super video. You are the first I have seen to mention about the tail stock quill pointing towards you. I thought mine was bored incorrectly. It's about .003" per 4" travel. Is that about right? I was trying to figure out how to straighten it but thanks to you I don't need to. I do find it frustrating, though, that once I set the tail stock offset for no taper I can't repeat it unless the quill is extended the exact amount.
great videos, keep it up :D
Did you check the vertical alignment of your tailstock as well to see if it needed shimmed up? I like the rigid tool post, you should have no problems taking cuts only limited by the power of the lathe now. :-)
Question on your tailstock alignment method. Wouldn't it be preferable to do the alignment with the quill retracted? That way when it is fully extended it will be biased towards you and cutting pressure would tend to push it straight, I would think.
Anyway, great video as always!
Stefan - great video . the method of aligning the tailstock is very interesting. Is this the same method you use to align the chuck when you have it on your quick change on your tool post for doing small hole drilling?
Hi, Stefan! Thanks for you video. Your level of details very high as usual.
What you think about main lead screw protection (like a spring cover)? Is it necessary? I heard few different opinion. One of them - it is hard to see junk on screw threads and remove it at the right time. What you think about it?
Beautiful machine. I love how clean and extremely well maintained all your equipment is.
Stephan, have you heard of Kawasaki precision drill chucks? I came across one at a market for $1.50 lol
It is keyless 10mm zero close jaws. Seems to be very high Japanese quality. But it’s quite weird. Both top and bottom halves turn in the same direction. It works but I’m sure that I’m doing something incorrect using it and don’t want to damage it. I can’t really find any info on it apart from the company. I was wondering if you knew what I’m on about. Thanks. Matt
How do you know the tapered hole in the quill is centered when aligning the tailstock this way? Couldn't you end up with perfect outside OD alignment to your stock in the chuck, yet the taper be off-center and create issues?
Killer tailstock alignment technique.
I started watching this when you published it, but set it aside until I could give it the attention it deserved, once again you've done the miracle of making something *appear* obvious and simple when it seems (to me ) to be difficult and maybe not worth bothering with (tailstock alignment) it's a skill you share with ToT, ClickSpring and Joe Pie.
Your ancient grease/Ancient Greece joke made me vomit, dammit (best translingual pun I can come up with I'm afraid, I have the monoglot curse of the English:))
I like how you included footage of you getting bitten by the C-clip
could you put the quill in the chuck jaws for aligning it just losen the adjustment screws clamp the jaws on the quill and then lighten the tailstock adjustment screws
Talking about linear scales. Which DRO kit you would recommend from ebay? I would otherwise get Mitutoyo but it cost around 1300€.
16:42 "Oh, by the way, I have this custom cover plate that fits perfectly." Wow!
Lol, thats the magic of cad,lasercutting and nice bending :D
looks great (lathe) ......21:15 maybe you could build some kind of leather flap that mounts with Tnut behind the new tool post to keep chips out of your cross slide. or even a sheet metal slide that you can slide all the way toward the back of the shield - when you want to use your compound for tapers etc........ but when nothing is mounted you slide it against the tool post
Hi Stefan, I just purchased a Emco maximat super 11, it’s basically all together with a the stand and backsplash guard , however it’s missing the number selection chart for the feed gearbox, is there any possibility you may know of anywhere in Germany that may have a few surplus pats for that machine. Thanks, JB
Very nice setup now.
Thanks Randy!
The only time I ever used a travelling steady was when I made a lead screw for a Myford lathe. Not a nice job because at every pass the burrs had to be removed from the workpiece !
Gday mate! Emco is looking gorgeous!
I’ve a question on the tailstock, I would have thought that it would flex further at full stick-out.
With your discussion of the taper alignment would it be closer if you were to align the tailstock on minimum extension(most rigid) so that it then sticks forward of the centre the minor amount
By being level at full stick out I think this is possibly the reverse of the desired outcome?
Cheers
Also, this assumes the taper is dead center with the outside of the tailstock quill.
I'm a beginner on the lathe and i have a question to the solid tool post. When i turn a square shoulder i use the Z endstop on my lathe. The workflow is to drive the carriage to the Z end stop. Engage the tool post slide (which is missing in your case) to a certain Z dimension minus ~0.3 mm. Turn off material to a certain diameter using powerfeed and the Z endstop. Finally turning the shoulder face to the precise Z dimension (plus ~0.3 mm).
Having no tool post slide i think you use your carriage handwheel and dro to turn the shoulder face, right? In my case the resolution of the carriage hand wheel is quite rough. Is it even possible to drive it to a precise position or Z dimension?
Wow nice set up. Your lathe is cleaner than my microwave! Cheers! : )
Love the mods you have made Stefan, just curious about your method for aligning the tailstock. Are you sure that the outside of the quill is perfectly concentric with the quill taper?
Thats something you better check beforehand, absolutely right :)
I loved the bushing removal. “Oops”
I'm surprised Emco hasn't asked for drawings so they can make your mods a factory option.
Jim's videos robin renzetti will want a cut. Lol
Emco was done making small machines decades ago. Not enough money in it for them with the entry of the Chinese.
@@37yearsofanythingisenough39 This Lathe later was redesigned and labeled as the Super11CD. It had a headstock & Cabinet sheet metal change . It was powder coated a light gray color, as was the back splash guard. The left base Cabinet was black and the right where the electronics base & doors were painted with red powder paint. The CD version was sold with the Base & back Chip guard integral instead of optionally. The Lathe was still offered with 2 spindle bore diameters. The larger spindle had a 1.375 bore which allowed for a optional 5C collet closer with a D1-4 Cam-Loc mount spindle.
I bought one in 2001 which was ordered as single phase motor but was surprised when found that they were shipped with 3 Phase motors with a expensive Digital inverter mounted on the back right Cabinet. I used a 50 amp dryer outlet for power.
This machine was later upgraded again with variable speed spindle control revised sheet metal & rear splash guard and called the EMCOMAT 14D and could be ordered with a Digital DRO factory installed. Unfortunately the price has climbed to nearly $20,000. today. A beautifully made, high precision Lathe made to a quality not to a price point.
Do you still offer rebuilding of dovetail ways of small machines as a service or do you know a company which does a good job?
Is
Is that a custom way wiper on the tailstock base?
I figured you were building a new tail stock.
You are aligning to the OD of the tailstock quill, so are making the (probably correct) assumption that the morse taper socket is coaxial with the spindle.
Why not just put a coaxial indicator in the chuck and pick up the taper bore?
If you set up the tailstock spindle on the outside. How do you account for any off center or error on the spindle bore? Or do you just assume the bore is perfectly in the center of the spindle?
Never asume, always check. I should do a tshirt with that slogan ;)
I spun the quill in a pair of v-blocks and checked the concentricity. My guess is, that the morsetaper is centerless-ID-ground, because its running darn true ;)
I can only dream of my lathe being that clean, beautiful work on the modifications. Doesn’t your tailstock alignment method assume that the OD of the tailstock is concentric with the bore? That may be a reasonable assumption, but the ultimate test is probably a test piece turned between centres.

We call that "Chinese Mystery Grease" here in Canada!
Is that not feed through grinding not centerless?
I need to know where he get's his shim stock. I can't find it without it being 6" wide. I found one 0.5" wide, 0.006" +/- 0.10", 100' I might buy. 80$
Stefan, why did you not use a centering dial indicator in the chuck and clock the morse taper hole ? Would have saved finding stock and having to turn it.
Watch my video "Are indicator stands made out of rubber" - Indicating with a rotating indicator (or a centricator or something in that range) all suffer from sag due to gravitation.
For side to side thats usualy not a big problem, but for height, you will be off, if you dont compensate for it.
@@StefanGotteswinter Thanks for your reply. The only reason I suggested the centering indicator is that when the Boley Service Engineer comes to check our CNC lathe he does it that way. He puts a co axial indicator in the headstock and checks that the tool turret is centered when he asks the software to center the turret.
I put a DTI in a collet in spindle and indicated the tailstock, was a pita. I should've re-watched this video first 🤦♂️
Thanks for the tips.
There's solid, and then there's Stefan solid. BobUK.
Thank you Stefan, many things to be shamelessly copied, when are you going to start your own scraping class? I want to be on the waiting list!
@Richard King
I did not notice you giving credit to those that imparted knowledge to you? Everyone has picked up ideas from lots of others, I don't feel that everyone should have to explain where they learned their knowledge from.
