[@IrenESorius]

Thank you kindly for your excellent explanations through the animations,, 💖🙏💖 You are a 1st class teacher and a true star, Gena,, 🌟 Cheers from Sweden,, 🍻🥰👍‍‍👍‍‍

You prove that seriously accurate work can be done without spending a fortune on tools and machines. It is inspiring to see what someone with knowledge and determination can do in metalworking.

[@gena_bazarko]

Yes, you're right! Even without an autocollimator, this repair can be done very well, using an accurate level, an ampoule for which, with very high sensitivity, is not at all expensive, can be bought on Aliexpress. Then you also need a thin monofilament and a simple microscope, which is also accessible to everyone.

[@andli461]

@@gena_bazarko Monofilament as in fishing line? Trying to get my head around how such a setup would look like and work…together with a microscope. 🤔 But I need to think a bit longer I guess. 😆 Can’t wait for the next episode of this journey. Impressive, interesting and educational as always!

[@somebodyelse6673]

@@gena_bazarko - years ago I watched a video from "Eddie the Grouch", titled "DIY Machinist Level". He made a sensitive level ampoule of sorts, by gently flexing a plain glass tube filled with butane to get a controllable arc. His application didn't need it to be calibrated (he only needed relative change to check for lathe bed twist), but I think you could make one exceeding commercial ampoule standards 😀

I'm enjoying this video series very much. It's a huge project and actually the work is a gripping drama. I am so looking forward to a successful outcome! Thanks for sharing Mr Bazarko. Slava Ukraine !

[@МаркіянМандзак]

Thank you for those animations. They are very informative. Keep it up 👍

[@GoldenAgePuritan]

Great animations. I think your explanation of machine way correction is the best on youtube. I agree about enjoying this work. In an all-too subjective world, this reality based activity is bliss.

[@gena_bazarko]

Thank for compliment! You phrased it very interestingly about the subjective world. Indeed, I thought about this too. People can see and interpret certain circumstances in diametrically opposed ways, and this is a problem. But in terms of machine geometry, the situation is much better. The error is obvious, the correct path is just as easy to determine. There is no duality, there can only be options, without antagonism. Probably, if everything is “sorted out”, I don’t know whether the translation will be correct, I mean, if you really understand it, then you can come to the same clarity in other problems. At least for the most part. But it is obvious that this has not happened yet.

[@GoldenAgePuritan]

@@gena_bazarko The translation is perfect. Machine restoration is a sanctuary from the chaotic world.

[@gena_bazarko]

@@GoldenAgePuritan Restoring machine tools and creating machine tools are almost the same thing. And the creation of machines is technological development, which means an improvement in the chaotic world). So let’s make the crooked even, striving for the best!

Slava Ukraini 🧡🇺🇦 your videos and animations are amazing. Doing the animations must be as much work as the work itself!

[@hardwareful]

Precision is absolutely fascinating. It's one of the defining disciplines for civilization.

[@wktodd]

Excellent work as usual Gena

[@paulmace7910]

Amazing work. The autocollimator is the ideal tool to have for this application. Much more accurate than a precision level. Thank you for sharing.

[@gena_bazarko]

The precision level is also very accurate, but it only works in the horizontal plane. The autocollimator is equally effective regardless of the orientation of the plane relative to the horizon. These are completely different possibilities.

[@bclare2544]

Excellent work Gena.

[@stevenhavener7327]

Another Masterclass !! thank you , best regards Steve

[@mceajc]

This is fascinating. I own a small (1 meter long) lathe, and seeing this makes me wonder if I can improve its precision, as it is now 60 years old. I am impressed by your passion.

[@Rob_65]

Wow, this is a very nice series of videos. I love how you use basic techniques and equipment to make miracles happen 😁 You not only show great skills on using tools like the autocollimator but in other videos you show excellent use and knowledge about the repeat-o-meter and a bubble level. The different animation techniques also shown in this video are very good. You English is good but I do understand why you use the computer generated voice-over. I am in the process of building an autocollimator with cheap Chinese lenses and prisms, using a webcam instead of the eyepiece with the reticle (XY scale) to perform the measurement. I like how you use the smart phone to record the measurements.

[@gena_bazarko]

Hello! It’s interesting how sensitive an autocollimator assembled from inexpensive components will be. By using a webcam, this can and will happen, I admit that there is some probability of getting a good result.

[@ConcentratorSupportLtd]

An excellent video. I have to perform a similar operation on my antique horizontal mill. The guides are shorter such that I can avoid the autocollimator (I don't have one), but this illustrates the procedure.

[@gena_bazarko]

This is true, probably, up to about one and a half to two meters, it is quite possible to do without an autocollimator. It is enough to make or find just a good STRAIGHT EDGE. And have a good bubble level. Again, STRAIGHT EDGE needs to be checked with the same bubble level.

[@pirminkogleck4056]

very nice work ! i like your channel ! Greetings from Austria !

[@mechatronicsfun4467]

Захоплююча історія! Я незмірно вдячний!

[@stijn9957]

very good job, these videos are always great to watch!

[@nickj2508]

I look forward to the next video

[@nothcw]

i prefer your voice to the machine generated speech

[@gyrogearloose1345]

A bit of both is OK for me. Cheers

[@erikpecchi7462]

you can make up a linear slide bearing block and rail,and mount it to a cold rolled flat stock to sit on top of the factory flat surface right above your vee and flat ways, make up a carriage to mount a grinding wheel and motor, with a adjustable Z axis for taking grinding passes off of your high spots to get ways back to straight , would save alot of work.

[@gena_bazarko]

This is certainly true, but much less labor will be required if the repairs are carried out according to my plan.

[@erikpecchi7462]

@@gena_bazarko I Just thought I'd Mention it, as it seems you have been rebuilding all your Machines just like I like to do when I get a new Machine , I seen some Machinery Rebuilders they had a portable Linear rail that had a Bridgeport style milling machine head which has the Z axis travel built in, along with the spindle. Also the work you put into your videos is on another level with the animations this helps to explain to people that are new to machine rebuilding and metrology measuring devices at micron or smaller .

thank you

[@therealspixycat]

How can you make sure that the 3 segments say plane alpha are all the same and are not slightly twisted from each other? The twist could be caused by the wear in the middle.
