IMPORTANT SUPPLEMENT: The coplanarity check described in the video might be misleading because of the pictures being taken with various setups. The audio comment I give at the same time is a little abstruse, sorry. The following instruction might be more comprehensible: To determine coplanarity, two sub-tests must be fulfilled: 1st test: Place indicator base on one surface, sweep on other surface from indicator position "outermost" to indicator position "innermost" as well as move along the slide. Reading must be constant. This ensures that the surfaces are parallel. 2nd test: Compare indicator reading in "forward" and "reverse" position ("forward" being e.g. with base on left surface, taking reading on right surface, "reverse" being with base on right surface, taking reading on left surface). Readings must be equal. This ensures that the surfaces are at the same height, i.e. coplanar.
Trust us! We all know why you took a month off. In the States we call it Singing ( I loathe it) or Howling. I’m sure Stephan agrees with your work. Great Work! Do I hear Collaboration?
Stefan ich hoffe dass du das nächstes mal, wenn wir uns sehen, wieder so herzhaft über meine hässlichen, aus rostigen Abfällen geschweißten Messuhrensockel lachst :D
And finally we all know why Stefan keeps calling his results “fairly decent”. 🙄😂 I’m sure there’s a diagnose for this...and I love it. 😉 Great work! Subscribed.
The mighty algorithm brought me to your latest video (the Seiko lever) first, and now I’m going through the catalog in order. This is impressive material! 👍
WOW! This is one of the most inspiring rebuild videos that I've seen. You and Stefan are now my top references! Thanks for sharing this kind of work, many people would not have shared that kind of knowledge.
truly inspiring..........i am from india and i own a victoria milling machine universal type since 45 years almost 60 to 70 years old made in England. your video will definitely help me to make my dream project come true. thanks bro 👍
That labyrinth for the oil ports is by far the most impressive bit of engineering ive ever seen and the only time I’ve ever seen a solution and was like wow I wouldn’t have ever thought of that but it’s so simple
Back here again, for the xth time. One seems to find always some detail which was missed last time. Very interesting and exceptionally well presented. This time I might have the courage to start my FP4 Z- slide scraping.
An amazing job with some extremely detailed and well thought out modifications like that oiling system. So many videos here on YT and forum posts today that show a few repairs, a cleaning and repaint and then calling it a rebuild or reconditioning have in reality no idea of what those terms actually mean.
"Unbelievable" Obviously a type "A" personality..........fantastic detail...........I can only congratulate you and hold your workmanship in awe. Cheers, David
This video is like candy for an engineer! Your attention to detail and quest for perfection using novel ideas and incredible mental and physical endurance and work ethic are amazing! Usually when I watch UA-cam videos that show machinery reconditioning, nightmares are the result! In contrast, this video is the best I have ever seen regarding machine reconditioning and restoration.. simply the best. Your mill is incredible and so is your work.. Bravo!
Many thanks for your kind words. Your comment means a lot to me, because I was always unsure if this slideshow would find any interest on youtube at all. All the best, Alex
Fantastic work. You say you are not a professional reconditioner in the video, but you are certainly no amateur. Your work is carried out with amazing attention to detail, and your scraping work looks very good. In the future I want to do a job like this on my Schaublin 22, but my scraping abilities are not yet up to a level where I will take on such a task.
I have an old beat up deckel fp1 so this was really interesting. Incredible detail. I will have to watch it several times. Thank you. And if Nick Mueller liked it you must know what you are doing.
Nice work. Finding the mental fortitude to tear everything apart to fix the table tilt is... the right thing to do. The oiler was a bonus. I've been thinking about adding an oiler to an RF-45 type mill. It will be far easier, I think. And that's the best light I've seen on a mill.
Dir aus anderen Lagern eins mit den notwendigen Toleranzen zusammenzuspleißen ist absolut genial, vor so einer gelungenen Restauration kann man nur den Hut ziehen, bravo.
Vielen Dank, aber das war zum Teil auch Glück: Bei diesen Lagern lassen sich die Wälzkörper aus dem Käfig federnd raus- und reindrücken. Wäre das anders gewesen, hätte man die Wälzkörper ggf. nur mit Zerstören vom Käfig rauskriegen können.
I'm fixing up an old English milling machine and this video was a great help, I can only aspire to get the accuracy you have but I am helped by the wear in my machine being up to 10x more than yours ;,( very nice job and a beautiful machine!
Wahnsinn! Habe auch eine WF1 im Keller stehen, absolut tolle Maschine, mit Deiner würde ich da sofort tauschen, aber Klasse, wie Du das alles dokumentiert hast. Vielleicht folge ich Deinen Spuren, werde sie aber erstmal ausmessen, wie genau sie vor dem Refit ist. Weiter so! Abonniert!
Very interesting! Reminds me alot about my last 14 months with my FP2. It's a different machine and you went further than I did in disassembly in even removing the base from the column! I am only at 15:55 now but that is really interesting segment! I was really fortunate when I hopened my vertical spindle because everything looked to be in fine shape on an otherwise abused machine. I would have had no idea what to do if I was in your situation. I didn't think it was even possible to lap that at home and get it so precisely centered.
Well, Dennis, I guess coming up with such a solution is a result of being confronted with the problem and not having tons of money to solve it. Sure the damage was frustrating, but the way I see it, the spindle was already worn so I couldn't make it much worse. Fortunately the repair worked nicely. Thanks.
:D that is very kind of you to say, thank you. However, I cannot say what tolerances this machine had when it left Switzerland. But I bet the were very narrow.
Somewhere in the following decades, somebody will disassemble this and see the oiling labyrinth distributor assembly and think that the engineer was probably drunk when he came up with this :D Nice work!
wow! I skimmed trough the video a bit, but your explenations seems verry detailed! i saved the video and will rewatch it complete when i have a bit more time! Great stuff! subbed
Richtige gute Arbeit! Das Schaben und drum rum war fast eine Strafe bei der Maschinengröße nehme ich an... Das mit dem Vernickeln ist ein super Tipp. Weiter so!
I've watched this episode a few times now and am very impressed at your focus and endurance it must have taken to complete such a task. I'm sure as you say it ranks among the top best of Micron and more than likely better than originally produced. I myself have a new to me lathe that I have ambitions to undertake this process and am continually procrastinating knowing how much dedication it will take to achieve the results I'd like. I can only hope to get it to the level that you accomplished with your milling machine. Thanks for sharing your journey and maybe one day il finally finish all my other more important projects and tackle this similar daunting challenge. PS. I would love for you to help me build a new thread dial as you have engineered as my lathe seems to be missing the factory one and I really like your multi application design that you made. Cheers and I hope you find the time to make future videos to enjoy
Many thanks for your kind comment. I know, it may be quite intimidating to start a complete reconditioning. However, what assured me beforehand of my scraping capabilities was the test pieces I made. One of them was a house shaped prism (a testing tool for a precision frame level), all made exclusively with hand tools (saw, file, scraper) from round stock cast iron. For testing the geometrical accuracy of the prism surfaces (symmetry) I used two dial indicators at the same time. This project cost nothing and made me self confident of spotting, scraping and testing principles and procedures. Only thing left is endurance! Good luck for your upcoming interesting project. PS: Sorry for my ebbing of videos lately, but currently I'm so very busy with customer work.
Ha haaaa haaa "Martin the perfectionist." Up to that point I was thinking that Alex with his micron accuracy was the the perfectionist. Hopefully Martin doesn't have a UA-cam channel, I'd be lost for days in that. Love your work and Stefans as well, I'm afraid that if my machinings within 75 microns its close enough.
Excellent work ! It is very difficult to do what you've done; it takes a lot of resilience. I've done my Bridgeport the same way, which took less work than yours anyway. I managed to pull a 15 microns flatness over 600 mm, (6 tens over 24 in) but ask me how long it took (forever and a day) and in what life will I ever do it again; certainly not in this one. Congratulations and keep up the exquisite work !
Thank you for your kind comment Sir! And I agree, it takes resilience. Interesting, btw., that Mr. Connelli spent a whole chapter in his book discussing people who qualify as scrapers.
I have watched this about 4 times. I think another 10 and I will understand all of it. When you say cross slide you mean the fixed part that the table slides on to the left and right? My brain is calibrated for bridgeport type machines so I am all mixed up. I like the ingenious tricks you came up with to measure parallelism and co-planarity. Your indicator bases don't have to be pretty. Stephane would have hardened and ground them, blued them and engraved his initials in them, but you were trying to get the job done in your lifetime!
:D thanks for this very kind comment Sir, with this you've lifted me out of a bad day! Right, what I mean by "cross slide" is the part that connects the z-slide column to the x-slide table. Sorry if this is not a typical expression, English is not my native language.
Actually yes - If you have a toolroom mill that size rebuilt for example by FPS or Franz Singer in Germany, you are about in that price region. And people have it done! We had 10 Deckel FP2 and a FP3 rebuilt..
So, Alex, I found the time to watch the video during the weekend. I'd like to thank you sincerely. It seems like a very high quality job, inline with your friend's, the ones who makes fun of your dial indicator fixtures :) It has been very useful that you documented the whole process, start to finish, in one video, even slide show, it worked just fine. Many questions arise, both technical and not (like, how did you make do for 5 months without a milling machine?? :) ). What is of great interest though, and not related to your machine specifically, is how far can one get with rebuilding a machine. If one acquires the experience (not easy but not that hard I guess) and can invest personal time, one can, in principle, end up with a machine much more accurate than any home-machinist could ever afford! Which is amazing if you think of it...You gave next to nothing in terms of money and 5 months of your spare time (and a lot of work of course) and ended up with a machine that would cost 50k, if it was for sale that is.... Anyhow, great work, thanks for sharing!
Many thanks for your kind words. :D Indeed, being without a milling machine for five months is like losing an arm. But I have to admit that e.g. the wrenches for the spindle I made at work after working hours. Well, about the accuracy you mention: Yes, a lot is possible with physical and mental endurance by scraping and smart testing. But there is a certain limit of accuracy which you cannot improve upon. This is given by the machine's design. The more rigid the machine is, the better. Imagine reconditioning a machine for many 100 of working hours to find out in the end that the machine deflects due to it's own weight more than your scraping accuracy. In order to avoid this, make sure before reconditioning that the machine is well designed from a structural point of view and proven.
Yeap, totally right...Indeed I had nice machines as starting point in mind, machines that will pay back your effort and time if you decide to devote it to them....like your Mikron. Myself, I can't see how I could find the time to do this, even if I had the skills...Maybe if I have tought myself to scrape untill I retire from work....but then I might not be able to lift the heavy mill parts :D
The wiper is a universal one for ways, I got it from shop.dynatect.de/ in Germany where I work. I don't remember the particular type though, sorry. It was a one-piece length of 500mm.
You can weld that cast iron fairly easily. I don't know why this is a perpetual myth that you can't weld cast iron properly. Just put the cast iron in an oven or even on a gas grill. Once it's up to temperature pull it out immediately weld it and put it directly back into the oven. I did this with stick weld many times and it works perfectly. I'm not a welder by any stretch and this has worked every time. You do have to pick the proper welding rods and I can't remember which ones I used at this time but the information is out there.
I think you've done an amazing job on that restoration - if you can call it that - as you may not have actually restored it but considerably improved it ! A a slide show, this video worked well. I was thinking how green everything is in your shop but this WAS green but now isn't :) I, and I bet many others, would appreciate a 'machine tour' video where we can see all its features in action including power feeds, rapids, spindle speeds etc. Is it classed as a horizontal milling machine with a vertical head or a vertical machine with optional horizontal operation ? For instance, if you fit a horizontal milling arbor, is there support for the far end of the arbor as per H mills ?
Servus Fifi, du zeigst hier mal eine echte Maschinenüberholung, da passt einfach alles. Sehr interessant ist auch deine Vorgehensweise und die zielgerichtete Problemlösung. Wir haben uns schon mal auf einer Grillfeier in Markt Schwaben getroffen, vielleicht hauts ja irgendwann wieder hin. Gruß, Sepp www.kunst-mit-mechanik.de
Servus Sepp, vielen Dank für deinen netten Kommentar. Natürlich kann ich mich an dich erinnern, du hattest mir ja deinen spitzenmäßigen Motor mit eigenen Gussteilen gezeigt, sowie deinen gefrästen Polyeder. Würde mich freuen, wenn wir uns bei Gelegenheit mal wieder sehen. Beste Grüße, Fif
Very impressive work! Love that you explain all the details and put so much content in your video. This tube furnace is very interesting also... Is it an induction furnace? The coefficient of expansion must be very problematic between the quartz tube and the sealing element? Thank to put so much effort in your video ATB
Thank you! The tube furnace in the video heats by radiation (and heat conduction if you use Argon, e.g. instead of vacuum). And yes, I am always again wondering how the little thermal expansion of quartz allows for the high thermal gradients along the tube (e.g. from 1100°C in the center to 10°C at the water-cooled ends). Greetings, Alex
Subscribed. Beautiful and inspiring work, Doktor Fillafer. I'm looking forward to more! I was very interested to read about your incredible work on the GTP-13.
Agreed! Indeed, Mr. Renzetti's practices and thought processes are astonishing. Thank you for taking the time to share your thoughts and talents with us.
very good. i bought a boley 5lz reasently.... for cheap. and its very well warn. i may ask for help/advice when i get round to doing the repair work. now its still cleaning and inspection i love videos with some learning. great job
I once had to rebuild a spindle from a Kearney and Trecker Universal Mill. It used a tapered roller bearing on the tool end with the inner race surface being the shaft itself. We had no manual so the boss suggested we cut off the cage. Oops. From then on the mill was strictly a horizontal
@@anengineersfindings It wasn't really funny at the time. The machine was most likely built in the late 30s early 40s. It still had a US War Dept tag on it.
IMPORTANT SUPPLEMENT: The coplanarity check described in the video might be misleading because of the pictures being taken with various setups. The audio comment I give at the same time is a little abstruse, sorry. The following instruction might be more comprehensible:
To determine coplanarity, two sub-tests must be fulfilled:
1st test: Place indicator base on one surface, sweep on other surface from indicator position "outermost" to indicator position "innermost" as well as move along the slide. Reading must be constant. This ensures that the surfaces are parallel.
2nd test: Compare indicator reading in "forward" and "reverse" position ("forward" being e.g. with base on left surface, taking reading on right surface, "reverse" being with base on right surface, taking reading on left surface). Readings must be equal. This ensures that the surfaces are at the same height, i.e. coplanar.
Absolutely Beautiful work, very well done!
ATB, Robin
Many thanks, Mr. Renzetti. Looking forward to your future videos. Kind regards, Alex.
Nicest mill I've ever seen. That oiling labyrinth should win the God damn Nobel peace prize for science.
Sir, with your comment you made me laugh out so loud that my neighbors could hear it. Thank you for your kind words.
I agree. As impressive as the scraping if not more so.
very simular to deckel
Trust us! We all know why you took a month off. In the States we call it Singing ( I loathe it) or Howling. I’m sure Stephan agrees with your work. Great Work! Do I hear Collaboration?

Wow. Absolutely amazing work. Not many professional scrapers could work to your level of precision across so many planes.
That's very kind of you, Sir. However, I am sure that I cannot keep up with a good professional scraper.
what a precision...hand srcaping is very time consume work, this is not just a machine, this is work of art
This is one of the best restoration I've seen in a long time. Well done!
Absolutely brilliant work. Your mill is now more accurate than most surface grinders.
I like your special tools, scraping plate, special wrenches.
Sir: A tip of the hat for a magnificent job. Both for the rebuild and the clear and concise explanation of the process.
Thank you very much, Sir.
Amazing amount of work here!! Congrats for absolutely stunning job here and a great “video”! Cheers, AS
WOW! This is one of the most inspiring rebuild videos that I've seen. You and Stefan are now my top references! Thanks for sharing this kind of work, many people would not have shared that kind of knowledge.

I've watched this episode a few times now and am very impressed at your focus and endurance it must have taken to complete such a task. I'm sure as you say it ranks among the top best of Micron and more than likely better than originally produced.

So It's basically a 30K dollar rebuild if you could ever find someone with the skills to do it.
Actually yes - If you have a toolroom mill that size rebuilt for example by FPS or Franz Singer in Germany, you are about in that price region. And people have it done! We had 10 Deckel FP2 and a FP3 rebuilt..

The wiper is a universal one for ways, I got it from shop.dynatect.de/ in Germany where I work. I don't remember the particular type though, sorry. It was a one-piece length of 500mm.
many thanks Alex for the link!
You can weld that cast iron fairly easily. I don't know why this is a perpetual myth that you can't weld cast iron properly. Just put the cast iron in an oven or even on a gas grill. Once it's up to temperature pull it out immediately weld it and put it directly back into the oven. I did this with stick weld many times and it works perfectly. I'm not a welder by any stretch and this has worked every time. You do have to pick the proper welding rods and I can't remember which ones I used at this time but the information is out there.
looks like you did a great job
Incredible job! Thanks
This is amazing!!
Thank you for sharing it,
excellent
I like your oiling system Manifold, very clever
Groß got!!! guter gemacht! auf jedem tag ich will arbeit wie das tun.
cheers!
I think you've done an amazing job on that restoration - if you can call it that - as you may not have actually restored it but considerably improved it ! A a slide show, this video worked well. I was thinking how green everything is in your shop but this WAS green but now isn't :)
I, and I bet many others, would appreciate a 'machine tour' video where we can see all its features in action including power feeds, rapids, spindle speeds etc.
Is it classed as a horizontal milling machine with a vertical head or a vertical machine with optional horizontal operation ? For instance, if you fit a horizontal milling arbor, is there support for the far end of the arbor as per H mills ?
Servus Fifi, du zeigst hier mal eine echte Maschinenüberholung, da passt einfach alles. Sehr interessant ist auch deine Vorgehensweise und die zielgerichtete Problemlösung. Wir haben uns schon mal auf einer Grillfeier in Markt Schwaben getroffen, vielleicht hauts ja irgendwann wieder hin.

Servus Sepp, vielen Dank für deinen netten Kommentar. Natürlich kann ich mich an dich erinnern, du hattest mir ja deinen spitzenmäßigen Motor mit eigenen Gussteilen gezeigt, sowie deinen gefrästen Polyeder. Würde mich freuen, wenn wir uns bei Gelegenheit mal wieder sehen.
Beste Grüße,
Fif
Good video and very nice job! Well done!
I need a lie down now. Great job 👍
Excellent work.
Many thanks!
🙏 great work by you
Saubere Arbeit und wunderschön bilder... ;)
excellent, thank you for posting!
Fabulous job !!!
That is incredible!
Very impressive work! Love that you explain all the details and put so much content in your video. This tube furnace is very interesting also... Is it an induction furnace? The coefficient of expansion must be very problematic between the quartz tube and the sealing element? Thank to put so much effort in your video ATB
Thank you! The tube furnace in the video heats by radiation (and heat conduction if you use Argon, e.g. instead of vacuum). And yes, I am always again wondering how the little thermal expansion of quartz allows for the high thermal gradients along the tube (e.g. from 1100°C in the center to 10°C at the water-cooled ends). Greetings, Alex
Can you make a video on scraping and your setup?
Really amazing.
Wow well done 💪🏻

;D The little joys in life...
Subscribed. Beautiful and inspiring work, Doktor Fillafer. I'm looking forward to more! I was very interested to read about your incredible work on the GTP-13.
Many thanks for your kind words, Sir. I see you are also a fan of Robin Renzetti, whom I consider an incredible source of inspiration.
Agreed! Indeed, Mr. Renzetti's practices and thought processes are astonishing. Thank you for taking the time to share your thoughts and talents with us.
Glad to hear that my videos are interesting to you. If they are valuable to viewers like you, it is surely worth the effort making them.
Thank you for sharing
Great job !
********** excellent, and yes you win
20:36 ah, the good old "garage staple" calendar
very good. i bought a boley 5lz reasently.... for cheap. and its very well warn. i may ask for help/advice when i get round to doing the repair work. now its still cleaning and inspection
i love videos with some learning. great job
All the best for this challenging job!
I once had to rebuild a spindle from a Kearney and Trecker Universal Mill. It used a tapered roller bearing on the tool end with the inner race surface being the shaft itself. We had no manual so the boss suggested we cut off the cage. Oops. From then on the mill was strictly a horizontal
:D

It wasn't really funny at the time. The machine was most likely built in the late 30s early 40s. It still had a US War Dept tag on it.
