Dunno why, but the skill and how much care you always take, you are basically someone who I want to become some day! You always put a smile on my face no matter what 😂
Here we are with the final verdict: "You are a toolmaker... and you are sick!" ;) I love watching your precise descriptions and explanations... yeah... I'm sick too! ;( Nice to see that your scraping class payed off and you were able to turn the rotary table into a precision tool worth multiple times the amount it once was when shipped to Europe! A job really well done... awesome and beautiful... thank you so much for sharing!
It's the second time I've watched this series, I marvel at your expertise and care you've taken to produce, or improve the accuracy of this rotory table, wonderful stuff!, cheers, Dave
Stefan, I hope you never get tired of making videos. You make some of the best. I would be satisfied if I had 1/4 the machining skills that you have. Outstanding work on that rotary table!
Better to not say MIG But made by a German I got my work ethic and only excepting better from my self from my uncil Paul Schmidt AAA carpenter taught me when I got my start in construction. He would allways joke with me and say son there only 2 kinds off people in this world ! A German and those who do as Good ! I never do good work for the money I get. I do it only for self satisfaction of doing as best I can. nothing elce matters ! I was a Overhead door installer I installed as small as 4×5 for a lawn mower for a rich man to a 28'×28' FVL The door ran straight up and had 3 1.1/4 solid shaft with 10 6"×74" springs and a geared 575v 3ph opener and lots of blast doors in underground unrainium mines.
Awesome! I am curious how did you check that the bore was square to the base. I think a demonstration of the measurement would be a great video. Thanks for sharing your special talents with the world. Mike
Stefan, you have the inclination, the skills, the time and the patience that I wish I had. That said, I no longer need these things as I get as much satisfaction out of learning/enjoying from your experiences. Thanks from New Zealand!
I totally sympathize with your need to fine tune your equipment! Completely understandable and, once tuned up, you can safely rely upon your tools to perform at acceptable levels. All of your hard work brings peace of mind and confidence when machining stuff. Nice work, Stefan! :)
What an excellent series this was. I wonder how much difference there would be between your reworked rotary table and a high-end one. I love the attention to detail you give to all of your projects! Thank you!
I loved watching this project come together. I wish we could of seen you scrape it in, I find watching the scraping process extremely satisfying. Great job.
Excellent work, Stefan! It is nice to know what you are working with, rather than guessing. Having it known to be accurate saves time fiddling with it before each job. I also believe in tight fitting mounting keys, which mostly eliminate dialing in tooling...
The photography on this was very nice Stefan. The multiple angles really made getting a clear picture of the process easy. Thanks for the great vid man.
Really enjoyed that one Stefan thanks for posting. I think your comment about measuring otherwise you are guessing is a good one. I use the DTI a lot more than I used to and it can be surprising what you find in a setup that looks good. Keep up the good work - this is a shining example of how good you tube videos can be.
Awesome series/work! I really appreciate you showing off your skills and the process to make such improvements to the RT. Thanks for the great video series. As an aside, my family just returned from Germany, visiting family there (I wasn't able to make the trip, had to work). Found it interesting that all drinks are served at room temperature (no ice water), and refrigerators aren't common. Definitely different here in the USA.
We don't have air conditioning and central air, but i have never encountered an household without a fridge. I think that it is almost impossible to live without one (maybe from January to March).
Great series, thank you. I bought this unit a month ago (the smaller version) and now I wonder if I should be "messing with it". I phrase it that way because I do not have your skills or tools - and from your comments, the unit is probably good enough "as is" for the standard of work I can produce with my manual mill (working to 2/100 mm with ease, and 1/100 when needed, with extra concentration on the verniers).
Beautiful project, amazing accuracy. Watching this series has given me nightmares wondering what I'll find checking my tools LOL. Thank you for sharing this project, it's been very inspiring.
Awesome job Stefan!!! I raise my hat. The only thing left to do is slightly skimming the nut landing surface to get a clean surface there as well. (it seemes to be off a bit)
Superb series of videos... Such precision work. Very nice. Vorsprug Durch Technik the old Audi tag line really applies to the work you do on this channel. Many thanks for sharing your knowledge and skill.
Great work in all regards. The work on the rotary table as well as the presentation, explanations, camera and editing all move you close to the top in the metalworking areas. No stretch for length in the videos, overall a nice length and for a subject many people can relate to (upgrading affordable equipment). You deserve a lot more subscribers. I particulary liked the dial indicator cam setup on the surface plate. The dimension captions along the shaft were interestingly new, but seem complicated to make or might need some other font/color/ a special camera angle for more visual presence. In case you have not seen them, check out Marius Hornbergers vids, he occasionally uses a cropped screen capture of his calipers´ LCD for comparison between two measurements, which i find visually appealing. It also might be simpler to realize in editing. It freezes a part of the video for understanding by the viewer over time and location, which makes it kind of cool to not miss the information, even if not closely watching the video. As i see your comments on Tonys videos, i would also not wonder to find an occasional "subscribe"-caption somewhere in your shop :-)
Hi Stefan. I like your videos. 👍 Noticed your small hardening oven. Is that something, that I can buy somewhere. Perhaps in Germany. I have been searching here in Denmark, but with no luck. Per
Probably too late for Per's quest, but what you'd be looking for is a "benchtop kiln". They're easier to find in the ceramics and jewellery world than in the machining world - an art supply store or a jewellery findings shop is more likely to have one than a tool and machine supplier. (Yes, they'll go to much higher temperatures than you need for heat treating, but they'll run happily at lower temperatures as well.)
Congrats for your job. It is the most precise job I have seen on machining and mesuring....Man You are sick! But I am sick as well since I love what you are capable of.
Very nice! I'm interested in the boring tool with the facing function. Can you provide a link? Or maybe consider a future video where you use it and explain it's use and how it works a little bit? Also, I imagine the Morse taper test shaft was bought. How precise is that? It seemed like you considered any measured error was in the shape of the bore in the table and not in the test shaft. It must have been super. Thanks!
Hi Stefan, Really enjoy watching your videos, very informative never to old to learn. I notice you use a very nice internal micrometer never seen one like it and it looks a really nice bit of kit. Can I be so bold and ask what make it is and where I can buy one. Carry on the great work. Best wishes, Ian
Having doubts about that one, Stefan! Don't You have to move the indicator tip in a straight upward vertical direction - when moving from the bottom to the top of the test bar, to get the correct measurements You're looking for? You just moved it without thinking about altering the tip position in the axis You were checking. Switching to the stand, eliminated that error. Good job!
Stefan, you represent what it means Made in Germany, awesome as you upgraded the rotary table, everything you did was awesome, and like a bit of copper to block the worm, simple but very intelligent things (we did not see it), but we trust fully in your word..lol Grüße aus Chile
Immaculate job Stefan. Just one rookie question: When scraping the foot square to the back of the rotary table, how is the blueing done. I imagine some big angle square? Btw. Thank you for the massive dedication in your videos.
I have now revisited all your rotary table improvement videos, as I just purchased a used Optimum/Vertex 150mm table. It also came with the dividing plates, and I got the package for a really good price. Although the table was used some, the ugly sticky packing grease was still on the table. So I followed your first vertex video (before this series) and cleaned it all, and re-greased and oiled it The table was surprisingly clean inside, just like yours, so Vertex is doing a decent job. After I get some use into it, I will see what kind of improvements can be done. I haven't gotten into scraping yet, but is really curious about it, I and have several machines that needs scraping. I don't know if I have commented on this series before, but it is excellent work Stefan!! Very good, I learned a lot. Any plans for continuing the scraping series? I revisited your two first videos yesterday. I would pay for stuff like that. Thank you.
That table has gone from a reasonably functional tool, to an unreasonably beautiful, and much more functional tool. Excellent! I'm still trying to wrap my mind around that business with 'adjusting' the Morse taper. Since you've said it works well for machine spindles, I'll take that as proof that it works consistently. I just don't understand how, given the directions that force was applied, tool deflection, etc. I could maybe, kinda, see how it could be done as a boring operation with the small end of the reamer supported by a tailstock or something. I'll have to sleep on it I guess, maybe my subconscious will pick up a clue.
It was amazing that the three jaw chuck created noticeable deformities on the table surface. Good thing you were able to scrape that out! At one point, when tramming the table, you said the scraping gulleys were 2 hundredths deep. How shallow can you reliably scrape? Can you do gulleys that are reliably only a thousandth deep? That would be gulleys about 40 millionths of an inch deep...... Also, thank you sooooooo much for sharing all of this stuff, LOVE IT ALL! :) :) :)
Chucks are notorious for deforming parts on a Micron Level :) As for the scraping, with a bit of practice you can scrape with almost less than 1/1000mm (1 micron) depth
Wow. Just wow. I am an automation engineer on an offshore gas operation. I took a year off in 2005 and got to play machinist for an experimental aviation operation. That was so fun. Unfortunately the owner was impossible to work for.
You have no excuses now if Bozo the clown turns up in the shop. It can not be the fault of the rotary table. It's beautiful craftsmanship Stefan to achieve such precision with basic tools and excellent technique. Thanks for posting the video.
Fine work Stefan, The pursuit of perfection leads to madness. Or starts at madness?, It's a pleasure to watch your process and listen to your reasoning. Cheers, J.
This rotary table you got is interesting, looks like a cheaper version of the vertex tables. mine has INA needle bearing both axial and radial.It also has a hardened MT2 bushing in it
Stefan , You did a wonderful job on that rotary table . That will last many generations with proper care. I bet many wonderful parts will come off that with your skill . Just curious did you ever finish that steam engine ? Best regards Terry Lembke
Stefan, this rebuild of your vertex rotary table reminds me of the baby bullet vise Tom Lipton did for the give away box, that vise was about 25K when they were all done with it,lol Im sure vertex should buy back this one and pay you appropriately for it and claim it was their great vise that made all your work possible, that or they ought to offer you a job supervising their QC.
Wonderfull to watch and learn. I thought before starting working as a machinist That everithing should be done With this level of precision , but i got a big disapointment when i found out that wasent the case...
You've turned this already decent RT into a high precision tool! I have been trying to find these oil cups you used on this RT in a previous RT video. Can you tell me who makes them or where to get them? The factory oil cups are junk and dont work
Nice to see 0.01mm or better in concentricity, parallelism/flatness. I'm still confused, was this a real Vertex H/V rot tab (from Taiwan), or was it a main land China import that was a fake use of the trademark name? I just recently purchased an edge finder that was branded with laser etching on the body of the tool with Vertex, and in their artwork. But on the plastic box, it was Ver-Eagle which duplicated the trademark artwork. I'm not familiar with Jig boring machines, I think of them as very large machine tools. What makes a large tool more accurate then your most excellent work?
You either have a square granite to compare to or you make your own squares. The process is pretty much the same as making flats by scraping, except you are essentially working with angle plates.
Very nice build. And thanks for showing that order of scraping steps, that starting from the side parallel to bore axis wasn´t as intuitively clear (to me) as it probably should have been but seeing this is likely to allow me to leave many curse words unshouted in the future.
You have to start from the thing you can not change (orientation of the bore) and something you can measure (orientation of the bore to the foot-surface, then you can build up :D
Scraping provides a better surface contact, checking it with highspot blue on a surface plate confirms that. The quality level of a surfacegrinder needed to provide a 40..50% or better surface contact would be rather expensive.
I have started a trade in fitting and turning, and to my surprise your video on hand scraping was the main source of training. 👍
Dunno why, but the skill and how much care you always take, you are basically someone who I want to become some day! You always put a smile on my face no matter what 😂
Most excellent work Stefan! Enjoyed the whole journey.
Best, Robin

Your attention to precision detail is amazing.
Simply awesome Stefan!, there is a reason why Made In Germany is highly regarded! Amazing scraping job...congrats! :)

Great series. Hands down the most educational machining channel on the tube.
Always a pleasure to watch you perform your specific type of alchemy, Stefan. Why turn lead into gold when you can turn chinesium into germanium ;)
Haha, good one :D Thanks for watching!
Hot damn! That is one accurately modified rotary table!
Man, that was also really nice to watch!
Awesome! I am curious how did you check that the bore was square to the base. I think a demonstration of the measurement would be a great video.

Very nice finish and quality Stefan.
You give new meaning to the word "Perfectionist" Nice job.
I agree with Robin, a Most Excellent series. Extremely Impressive !
Enjoyed, like the tip on hand turning the lathe thread.....could have used that about 2 years ago on an internal brass part
Great video. While I will not scrape my table, I might check it out now that I know what to look for.

He really has OMD - obsessive machining disorder and some ODD - obsessive dimension disorder but we like him more that way !
WOW! That looks magnificent. If Tiffany's or Faberge made rotary tables , then they would look like this.! Exceptional work - as usual.
That looks beautiful!! Well done! Chris
The accent,makes the presentation laudable.

Stefan thanks for these videos, they help me make mine a bit better. Could you tell me more about the boring head you used?
Great work as always! Thanks for the great videos and information!
Immaculate job Stefan. Just one rookie question: When scraping the foot square to the back of the rotary table, how is the blueing done. I imagine some big angle square?
Btw. Thank you for the massive dedication in your videos.
I scraped it just against a regular flat surfaceplate, and used a large precisionsquare clamped against the surface to check the squareness.
Blueing against a large angle plate can be done, but is extremely tricky.
Hey Stefan,
Also from Holland a huge thumb up :)
Your video,s are so usefull for me, thanks for that

Excellent work. That tip on the Morse taper reamer is a good one.
Work of a genius or a mad man. I'm expecting a 8" table this coming week
This was an awesome series! I’m curious, is scraping preferable to precision grinding in this application?
Wow. Just wow. I am an automation engineer on an offshore gas operation. I took a year off in 2005 and got to play machinist for an experimental aviation operation. That was so fun. Unfortunately the owner was impossible to work for.
Phenomenal work! Thanks for making these videos!

It needs a case now. Very nice work Stefan.
A delightful level of Insanity shown and well worth a rewatch of the series 😆
Above and beyond. Like usual. Nice work.
Excellent work. I really enjoy watching your videos.
That was awesome .. now i have to go make mine better .. and hopefully not render it useless in the process .. thanks for the great series!
Always a treat to watch your videos 👍🏻
Wow really good job ! I definitely look up to your skills !
Fine work Stefan,
The pursuit of perfection leads to madness.
Or starts at madness?,
It's a pleasure to watch your process and listen to your reasoning.

Aren't all bagels rotory?
I think they are toroids..
wonderful work!
Brilliant work Stefan
This rotary table you got is interesting, looks like a cheaper version of the vertex tables. mine has INA needle bearing both axial and radial.It also has a hardened MT2 bushing in it
Stefan , You did a wonderful job on that rotary table . That will last many generations with proper care. I bet many wonderful parts will come off that with your skill . Just curious did you ever finish that steam engine ?
Best regards
Terry Lembke
Great job Stefan very very nice work!!
Thank you!
Stefan, this rebuild of your vertex rotary table reminds me of the baby bullet vise Tom Lipton did for the give away box, that vise was about 25K when they were all done with it,lol Im sure vertex should buy back this one and pay you appropriately for it and claim it was their great vise that made all your work possible, that or they ought to offer you a job supervising their QC.
really enjoyed your skill
Did you grind that micro cutter for the facing operation from an old end mill?
Yep!
Wonderfull to watch and learn. I thought before starting working as a machinist That everithing should be done With this level of precision , but i got a big disapointment when i found out that wasent the case...
You've turned this already decent RT into a high precision tool! I have been trying to find these oil cups you used on this RT in a previous RT video. Can you tell me who makes them or where to get them? The factory oil cups are junk and dont work
Nice to see 0.01mm or better in concentricity, parallelism/flatness. I'm still confused, was this a real Vertex H/V rot tab (from Taiwan), or was it a main land China import that was a fake use of the trademark name? I just recently purchased an edge finder that was branded with laser etching on the body of the tool with Vertex, and in their artwork. But on the plastic box, it was Ver-Eagle which duplicated the trademark artwork.
I'm not familiar with Jig boring machines, I think of them as very large machine tools. What makes a large tool more accurate then your most excellent work?
"What makes a large tool more accurate then your most excellent work?"
Because in scraping a jig boring machine "good enough" just doesn't cut it.
Stefan, you are very intelligent man!
So how do you scrape square (eg how do you achieve accuracy in squarnes)?
Easy, don't scrape round!
You either have a square granite to compare to or you make your own squares. The process is pretty much the same as making flats by scraping, except you are essentially working with angle plates.
Very nice build. And thanks for showing that order of scraping steps, that starting from the side parallel to bore axis wasn´t as intuitively clear (to me) as it probably should have been but seeing this is likely to allow me to leave many curse words unshouted in the future.
You have to start from the thing you can not change (orientation of the bore) and something you can measure (orientation of the bore to the foot-surface, then you can build up :D

Very well done! Thank you.
I'm confused. Why scrape the surfaces and not machine them. Surely machining will provide better surface contact??? What am I missing here???
Scraping provides a better surface contact, checking it with highspot blue on a surface plate confirms that.
The quality level of a surfacegrinder needed to provide a 40..50% or better surface contact would be rather expensive.
Got you. After watching your videos i now uderstand the concept. Thanks.
By the way you are late with this week's post. 😂😂
excellent video It's nice to see you just can't leave it alone. Good Job Are you ever going to find a tool you can't improve?????
I have a few that are just perfect, for example my Wohlhaupter UPA1 boring head. I would change absolutely nothing on it :)
Very nice project! Stefan, how many hours total do you estimate you spent on the project? I will budget twice as many.....
