I live in Ukraine. Now I am preparing for a major overhaul of metalworking machines for my workshop. I need to repair a lathe, a milling machine, a grinding machine. First of all, I need a special tool, a straightedge, a surfase plate, a 90-degree test angle, a 55-degree straightedge. I will make all these tools myself with high accuracy, (within a micron). This work will be shown in the video.

Hi - you Mentioned you have autocollimator mirrors for sale , do you still have them ? Thanks
Hello! Yes, I have mirrors for an autocollimator that I intend to sell. Write to me by email. In addition, there are autocollimators, 589 nanometer laboratory lamps, flat interference glasses and the like. [email protected]
Super job! Nice video too!
Your thoroughness is amazing.
Nice video! I was wondering if it would be beneficial to use a lapping plate wider than the other pieces? That way app points get equal contact time.
Amazing work well done
Fantastic. Very talented.
I want to purchase one , please share product details in description
Hello! Now I have for sale an autocollimator of 1 arc second, there is a 0.5 arc second, there is a 0.2 arc second. Everyone works in two coordinates at the same time. Autocollimators can be equipped with one, two or two plus a third mirror that fits onto the lens at an angle of 45 degrees. The set has a special plywood box with places for storing the set. The autocollimator and its accessories are tested before sale. Everything is in good order and corresponds to its original characteristics. Please write to me by email, I will provide detailed information and photo or video material. My mail: [email protected]
I don’t know if adds to anything but. You could, if you need, give your screw jacks finer calibration by making them with differential threads. 😎
There is a bolt with a thread pitch, I don’t remember exactly now, but probably 1 mm. The jack is made simply from a bolt and two nuts, plus one washer between the nuts and epoxy glue. Some technology is performed to eliminate thread defects on the bolt from dents when pouring and transporting the bolts, and an assembly technique is used when two nuts are in such a position that the bolt rotates tightly in these two nuts, without play. This position is fixed with glue. If you need to position with an accuracy of 1 micron, this is quite enough. If we are talking about 100 nanometers, then a very fine thread or differentiated thread is needed.
Вітаю! Даний метод вимірювання описав автор Dan Gelbart у своєму відео "Building Prototypes Dan Gelbart part 17 of 18 High Accuracy" приблизно на 23 хвилині. Цей метод він назвав "reversal method". Не думаю, що він є автором.
Так, я колись дивився це відео, але відшукати його, коли готував свій матеріал, не спромігся. Дякую за точну адресу цього єпізоду.
what an awesome leopard paint scheme lathe you have in your workshop! You don't see much variation from the grey or green colour schemes usualy.
Hi again! Just wanted to comment on the AI- voice. Yours is much easier to follow. I find myself zooming out and not listening when it's the AI voice. I understand if you may prefer to do it that way. But I much more prefer your real voice. And it struck me how much ones own interest in a topic comes from the actual presentation. You definitely beat AI any day!
I love your unique way of illustrating! The physical demonstrations, the crayon pictures, animations. It's so good! And there's always a plan behind everything, like when you dropped the small tool to illustrate the raised burrs and crater from the impact. Don't worry about your English, vocabulary and pronunciation. It's perfectly understandable and not at all lacking! I'm a Swede and I know the feeling of grasping after the correct term. Feeling unsure of pronunciation etc. Keep up the great and interesting work, looking forward to all your future videos! And I hope the war will end soon.
Thanks for making the video! I am starting out as a home machinist with a cheap Chinese 7x14 mini lathe and a Sieg X2D mini mill. I am learning metrology so these will be my test and learning subjects to improve upon. Once I am confident with these I am planning a high precision mill with concrete or epoxy granite, so developing precision measuring, lapping and scraping skills are essential.
Hello Gena (short for Gennadiy?) The measurements you are chasing are surpassingly impressive, great work! I think you should look into Hertzian contact stresses as you go along. The geometry and gauging force of the tips of your (lovely) microcators can and should be accounted for when you are looking at 100nm increments. It will have an influence on the absolute values for straightness and flatness relative to the values read from the dial. Your videos are incredible. The visualizations are some of the clearest I've seen on the topic on KZread so far. Really well done. Also - are the microcator surface gauges still for sale? or have they all been bought already? Love from Denmark -G
Your English is very good. There is no need to have a native speaker check your English! Please only worry about producing more great videos. Slava 🇺🇦

Сколько микрон снимается за один проход дремелем ? А за полный крест?
Я вовсе не считаю, что дремелем работать лучше, чем шабером. Думаю что дремель снимает примерно так же, как и шабер. Только нагрузка на руки возможно ниже.
Я шатал мотал шабером махать + у меня есть гранитные камни, там только дремель !
To keep the stone flat as a reference surface that better to use only the Witworth method ( 3 stones A B and C ) or to grind the stone of a surface grinder with a better straightness as requested on the stones . the 3 flats / stones allow to reach incredible Hight flatness with not need of local scrapping . 2 stone surface loss the flatness , 3 never . A thing to carefully check with Witworth 3 flats is when you lap narrow surfaces and long surfaces , to stay perpendicular to avoid to generate yaw . The problem is the size of the stone compare to length of the surface to rework , if that a convex defect that ok , if that a concave defect that far more difficult as your stone work only of the edges. I use the chest board method , divide the surface in square and record each level UP/DOWN and rework each square surface , after I subdivide the previously square and over lap the pitch to avoid border effect and rework again . I am impress by the sub micron level you reach , perhaps you can try to measure '' in line'' so parallel strokes and in V so from left to right side and right to left both side with your level to check if you have yaw ?
Hi, thanks for a very useful video, i was scratching my head regarding the unknown quality of my straight edge and surface plate, rediscovering the truism that nothing is flat, straight or square if you look hard enough 🙂 As an aside, your method bears some resemblance to "Rollies Dads method" for determining the alignment of a lath headstock using a mandrel that is not necessarily straight or round. Again, thanks for a detailed and well explained video.

Very cool setup, interested to see more
How do you establish initial level points? How do you translate them to the other 2 points?
There are few such authors on KZread. it's a ray of light .
new subscriber here, this is wonderful, thank you so much from the USA, Paul
I really love your work! But I think in this activity as many variables must be eliminated as possible, and I think the variety in positioning your device on the plate is a candidate. I am no true technician, but I wondered why you chose to make a base on three lapped steel flats instead of on three off the shelf ball bearings. That would be easier to make, and theoretically should be better because imperfect flats in contact border on introducing the problem of overdetermination. Lasty a remark on creating a flat surface: as far as I know this is always done by alternately bringing three, not two, surfaces together. Two surfaces rubbed together always produce two convex shapes. Some sites where I learned a lot: Dan Gelbart, Huygens Optics and Stefan Gotteswinter. And: Principles can be transferred between different trades!
Hello! I specifically showed that the heels of my device are not flat, they are ground in such a way, due to certain circumstances, that they are convex. This is a fragment of a ball, only the ball is very large in diameter, about 100 meters. It is precisely this ball diameter that is best used in this device, in which case it works best. If you use completely flat heels, it will be a little bit worse, but only a little bit, if you use small balls, the device will react to local defects of the slab, and this will not be convenient.
@@gena_bazarko you are of course 100% right😁

If you want to improve your flat honing quality and process stability , you need to use cross grooved flat surface as if your surface is too large / big your part ''float'' and abrasive is not equality spread on the surface OR you need to lift very often to let the abrasive film return equal Use soft flat surface help a lot as abrassive tend to stay stuck in the soft surface and cut the honed plate rather to roll .
Id be interested in a video about your wooden crane at the start of the video
Well, this small crane is very simple. There will probably be a case when I show how I do something by lifting a load with this crane, then I will quickly show it in more detail what it is like).
Unbelievable!!
You know about the three plates method, don't you? I say because it's clear you've never bothered trying it out even on a small piece and checking it, or getting it checked, which is something we nowadays can do (and you seem to), that Whitworth couldn't back in the days, though you'd find out it wasn't even needed in first place. Entire machines have been rebuilt by keeping three 1mx30mmx50mm solid stock bars flat, offering exactly the same precision than heavy plates of any material, minus their expensive maintenance, and the labour and implied lack of accuracy that implies using these with heavy parts. And please, stop using a dremmel and abusing of the stones to achieve "flatness". It's just lame, and you'll have a hard time achieving sub 1-micron continuous across that length that way. An old discarded file kept properly ground, a regular stone, and elbow grease is all that's needed to take three pieces of stock as flat as wanted. And by the time you've done it once you'll have already mastered the technique to the point where right after applying the blue, you eyes can tell you where you are with a high degree of accuracy. It's not that hard, there's no need for tungsten carbide tips, super-duper precisely flat stones made of star dust, or electric scrappers.
Hello! Now I need to make this straight edge for practical work, the surface grinding machine is disassembled, and I need this straight edge to repair it. The three-slab method, in this case, is an extremely long way, and very expensive, you need three slabs of 800 by 800 millimeters, they need to not only be available, but also scraped out, before scraping out this straight edge from them. Using my method, I will get the result I need in a week. You can scrape it with a scraper, you can with a Dremel, it doesn’t change the essence, only the flatness in the end is important. I'm not against the scraper at all.
You can make the three plates method with three rectangular bars, no need for a plate. Make one of the sides squared and that's all you need for that job. It's not expensive, it does take some labour (two or three working days, depends on you) and that's all. Every time you want to use it you check it and give it a light scrap if needed, as it tends to release internal stresses overtime, and it's ready for whatever you want it to do. Most surface grinders don't even come scraped, so you would end up with something better than new. And again, no, dremmels are not used for the most part, and much less the lousy way you're using it. Abusing the stone to flatten afterwards will only create several sub-planes where you just want to have a single continuous one. You'll have a harder time achieving sub 1-micron with you current method that would of doing things *as they should be*.
@@stupid-handle Hello! Thank you for outlining what you see as a more rational approach to solving this problem. Perhaps at this moment, I don't fully grasp everything from what you've written. As I understand it, to create a plane using the three-plate method, square blanks are needed to allow for a 90-degree rotation of the blank. Regarding the Dremel, I don't believe it's the best method, but I have used it, and it does work, albeit perhaps not as well as other methods. When working with this blank, I'll likely try using a scraper. I'll be posting new videos over time about this project. If you watch them, please share your thoughts.

Haven't I seen your video before? I guess they all seem to be the same to me. "....The peculiarity of this method is that I control the position of the measured plane. ..." It's a pretty peculiar method but I'm not going to bother to figure out what you are trying to say. It's too difficult for you to figure out and I'm not going to figure it out for you. What I find pretty peculiar is that you are from some part of the world where you can't just buy a tool if you need one and nobody has the common sense to realize that if they can't buy a necessary and fundamental tool then they should be selling them. In the light of the previous paragraph, Granite is simply easier. If we were to think through the processes of tool making, I need to make basic tool A to make basic tool B to make basic tool C...the chain of precision processes is the shortest. All you need is a lap, the flattest surface that you have and a way of checking the finished product. It is already stable and an easy material to cut with tools that need little maintenance, expense or preparation. If nobody on you your entire continent can buy a straight edge then you should plan on selling surface plates and squares as well. After-all, if nobody else has that much common sense then you can stop making suits and start making sense.
Hello! You wrote such a long comment, but unfortunately, probably due to the translation into another language, I did not understand everything exactly. Really, I'd rather make straight edge than buy it. It will be very expensive for me. And I can do it quite successfully myself, and then I can repair the metalworking machine. I think that's good.
@@gena_bazarko Oh good. You are alive. Make a note that I did give you the right answer. Simplify the problem.
@@gena_bazarko ...and with further thought...There is an easy way without fighting government regulations or personnel. Simply take any measuring device and measure the length of your machine ways. Then take the same measuring device and measure your straight edge only when you do so mark the best area of the straight edge in pencil. Then turn your straight edge 180 degrees measure and mark it again. Now take the straight edge over to the machine and scrape the machine so that it is the best in both orientations of the straight edge. By doing this what you will be doing is following the same procedure as is used for lapping a part.
Wow, this must be an American, one of the ones who writes thoughtlessly rude comments out of pure ignorance and with no appreciation of the circumstances someone else is living in. Gena does remarkably refined work, similar to the best anyone else has offered up for free on youtube - on the level of Robrenz, Stefan G, and other genuine practitioners. He produces extremely informative and educational material, reflecting his experience and skill. Compared to this, most commercial American engineering is at the level of someone banging rocks together. If you are able to read the news, perhaps you can guess why he is not setting up a factory to manufacture straight edges in Ukraine this year? You've not said anything interesting, and it seems very unlikely that you have even a fraction of the knowledge on display here.
@@mileshember3501 Good. I guess you know better than I would, so you can just move on to insulting someone who gives shit what you know.
I had colleague and we used to place industrial machines, he had ca 15cm x 15cm metal rectangle with a like ca 10 cm long tube. It went nuts just by placing some smoking paper at on side, it was not DIY.
Precisely flat surfaces can be done with the three plates method. It does not need precise instruments.
/r/confidentlywrong Yes, we all know about the Whitworth method. But how do you measure where you are? And what about when you get to the point where the bottom plate is always convex, at about 2-3 microns flatness? Watch Renzetti's videos (and the others on this channel) - these guys pushed past the limits of the 3-plate method years ago.
@@rodfrey The improved Whitworth method proposes using a paint to track the progress... And, as for the precision, I guess, repeating is the way ...
Hello! I will need this precision strip 1070 mm by 60 mm in the near future to repair a pair of linear movement. I will complete this job in about 40 working hours, and I will have a very accurate tool that I need. Imagine if I go the route you suggested, first I need to make three surface plates 800mm by 800mm. Then, using one of these plates as a reference, make this precision strip. Do you see the difference in the difficulty of solving the problem?
Excellent video, clear and concise!
Sir, you are a genius! Thank you for sharing your knowledge and inventions!

Hello, you might be interested to see Huygens Optics. ❤️🇺🇦🔱✌️
Thank you! You understand well what deserves attention on KZread. This is a great and very useful channel. I've been watching it for a long time and subscribed to it for a long time.
Gena, I've enjoyed your videos and I think using an AI voice is a wise decision. I do the same on my channel. I know some people hate it, but they forget that these videos are meant for many. Also for people who have difficulty understanding English with a heavy accent. The same people forget that it is way more work to write down all your text, feed it to a voice generator and paste the spoken text back in the video. Way more work than a voiceover chatting incessantly. So you are doing many a service with this extra effort, and I applaud you for that. 👏 I myself am sometimes busy with very accurate measurements, and I wonder how you take into account the inevitable deflection of the beam due to gravity. My heavy cast iron surface plate flexes up to 3 microns under its own weight if I balance it not correctly, so the long slender beam you are using may sag even more. 1µ/m is an extraordinary result!
Metal bars will change shape if they are too long to resist gravity from one end to the other... that's why they need to be vertically thick enough too manage their own weight... and metals will expand or contract with temperature changes... Granite will not change shape... it is stable and not affected by its own weight or by temperature differentials... that's why "surface plates" are made of granite... because of their stability when their... surfaces as referances... are required for measurement purposes... His granite beam looks like sawed lumber... because it does not need to look pretty... it just needs to be massive enough to bridge the size of the surface area of the required measurement zone... As a bonus... size overkill is easy and relatively inexpensive... when done with rough sawn granite... This genius really knows his stuff... and with that knowledge... with his... "back to basics"... understanding of immutable laws of nature... develops and uses... "simple looking tools"... which can make incredibally accurate measurements... but simple tools... ???.... they are not... basic tools... ???... yes... Simple tools... ???... no... Meticulous tools... ???... absolutely... Amazing tools... ???... definately... !!!
Sorry but I don't understand your method. Did you put the bubble device in the middle and then adjusted the jack screws until the bubble was centered and then moved the whole bubble assembly across the surface left and right to see the deviation from the center position (call this a datum)?
This method consists in the fact that after each movement of the bubble level, using jacks, I bring the bubble to the central position on its scale, and from the microcators I see by what linear amount the movement occurred. We select the measurement scheme arbitrarily, based on current tasks. I have already tested this method with practice. High accuracy is achieved. I made the same surface strip with an error accuracy not exceeding one micron. In the future, I will show this work in my videos quite clearly and in detail, having done it directly on this sample.
@@gena_bazarko I think I understand what you're doing. You're using the bubble always level (perfectly horizontal) by adjusting the jack screw on the right and you read the right microkator to see what the deviation is. By traversing the bubble over the straight edge and adjusting the screw on the right, you map the surface deviations so you know where to scrap/polish or whatever you use to remove minute material
So, the fact is that in order to place the bubble exactly in the center, you need to adjust the microcator at a distance of one meter to one micron. Raise it a micron higher, and you already see that the bubble has moved away from the center to the side. Therefore, the accuracy is very high. The microcator scale is much more accurate than the bubble level scale.
Hopefully you've annealed those welding spots of the reinforcement, or you'll see later that your flat is not flat any more. Usually those flats are built from cast iron, kept outside for years to release any internal stress.
Preliminary circumstances have developed in such a way that these actions have been completed by approximately 98 percent. Because as the project progressed, the plan was adjusted.
