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.

@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.

It's sad to see someone get so full of themselves they are either incapable or unwilling to learn anymore.
Looks like Emco had full Renzetti-Gotteswinter-treatment😁 Very nice job Stefan!
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.
this machine is still the most gorgeous little lathe on youtube, and so quiet!! i will never get tired of it turning so effortlessly
Thanks Stefan. That lathe is looking good. Definitely some great upgrades. Cant beat the full leather covers.

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 ;)
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.
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.
Hi Stefan, thank you for taking the time to make videos for us. I enjoy them very much :)
Nice updates Stefan. I have the slightly smaller Maximat V10P and I will be adopting some of your ideas. Dean Bristow.
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. :)
Awesome video Love the upgraded lathe features
You are very generous with your knowledge, thank you very much.
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.
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
great job Stefan , I love the way you worked on making sure you have the best coverage possible on the ways .. ENJOYED !!
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
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.

The scale and read head layout is neat, and the soft covers and steel armour is a tidy setup. Well thought out👍👌🇦🇺
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 have this machine so for me this video was solid gold. Thanks!
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!
What a great looking shop you have.
Thanks for the informative video Stefan. Steve
Love them lathe mods, Stefan😊. The work you do as always is exquisite. Thanks for the video 👍😁👍.
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!

@@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.
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!
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?
I like how you included footage of you getting bitten by the C-clip
Your lathe mods are coming along well . Cheers .
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.
Making a great little lathe fantastic! I wish we had a place in the US that would cut and bend like that....
Thank you Stefan, brilliant idea!
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!
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.

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 ;)

Beautiful work!
Nice looking set up !
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
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?
@StefanGotteswinter
5 жыл бұрын
Thats something you better check beforehand, absolutely right :)
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?

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.
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
Very nice setup now.

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. :-)
for centering the tailstock I use an axial indicator, is way faster.... try it if you have one :)

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.
I have never seen a tailstock aligned that way. I have done it by chucking a piece of round stock in the chuck and turning a tapered point. Put a ground dead center in the tail stock. Line up the points under magnification with quill fully extended. Either a good magnifier or a stereo microscope (if one was available). The other way I have seen to check the alignment of the axis (not just the points) is to put a shaft that has been center ground between the centers with the quill retracted. Run a dial indicator down the side and the top. This ensure the quill center axis and head spindle axis are parallel and coincident. You way is much faster though.

He did use the chuck for a center. I did this a few days ago with your method using a dead center in the head with the chuck removed and another in the quill. Had to grind the tailstock base as well. The previous owner broke the tailstock housing and rewelded it. I managed to get a new one from China.
@Worrsaint

@@Paulman50 Yes he did by turning an od on a piece of round stock and dialing it into the od of the quill. The method I was describing is going point to point so if the taper on the id of the quill is not coaxial with the od of the quill it is compensated for. The reason you turn a taper point as opposed to using a dead center in the spindle taper is to reduce tolerance stack. You use the actual rotational axis to create the point as opposed to what it should be. While the spindle taper should have very little run out, it is still a less accurate method.
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.
We call that "Chinese Mystery Grease" here in Canada!
Wow nice set up. Your lathe is cleaner than my microwave! Cheers! : )
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 !
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?
I figured you were building a new tail stock.
hi stefan, not related to this video but you have an L20 sleeve to fit your 26mm spindle, how do you remove it? i have one with a collar with 4 notches

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
Killer tailstock alignment technique.
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
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?
Hi Stefan, Great work, great vid and great explanation, TFS oh and great lathe. G :)
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?
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.

Stefan, your lathe looks beautiful in full dress, however the leather skirts will stink you out of your workshop if you do any serious turning. I have the same identical lathe, without your mods of course, and when turning I can build up a rather large pile of hot blue chips. I don't think the leather will survive any serious use. I love the solidness of your tool post base. I created a stainless steel shelf with a one centimeter edge on the left and front sides to control chips, basically the left half of what you created. It also is held in place using the unused holes of the travelling steady rest.
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?
