    Amazing! If I'm correct, you removed roughly 42ccs or 280gs of cast iron from the straight part alone! I hope you do a video on your carbide sharpening setup and ideas as well.

      Exactly! At the end of the repair I will calculate, first of all for the viewers, how much cast iron was cut off. After all, I have all the measurement data. It is interesting. And BIAX is really a very valuable thing, I know that, especially since we do not have similar machines.

    wow! hand scraping 1/2 mm is quite a work out. I find your technique of removing the high spots interesting and a perhaps good idea for such rough initial scraping. I will have to experiment with that. I have just found your channel and will look at your other videos with interest. I do some scraping and will soon be trying to learn the auto collimator.

      @@gena_bazarko Trust me, it is not too quick, Ive had to grind for hours and hours with a big 125mm x 6mm disk to flaten the initial stage of 3 surface plates 300x300mm in size prior to lapping and the initial peak to peak deviation was not higher than 2 mm. As long as you make sure you are constantly moving the disk and keep a very shallow angle of atack (I mean almost flat oposed to almost perpendicular to the grinded surface), the removal rate is not too high. Also, you could use a small inserts rotary tool (dremmel style) for the latter stages if you are afraid of making a mistake, because that is much more precise, but still, the same principle of constantly moving the tool applies.

      @AndySomogyi Sorry I don't agree with that at all. Of course there is some "uncanniness" when hearing an AI voice, but it is very understandable especially for those who are not used to hearing English every day, and therefore have more trouble with all the dialects and bastardizations and such. For example, the automatic subtitles by UA-cam also have that problem. It makes an incomprehensible mess of poorly pronounced or bastardized English and then a non-English speaker has little use for it. I applaud Genaddy for doing it his way!

    personally i would use a camera with a remote monitor on the auto colimater and move there mirror with a string angered as close to the bottom as possible to remove as much of my body effecting things as possible ( yes the camera will also output some heat into it but its way less and its constant and since its constant its also much easier to compensate for unlike when you go back and forth (first you have to compensate for the heat as you are there and then compensate for the lack of heat when your not there ). unlike mine that comes and go as i go back and forth between working and reading it. plus i dont have to spend time going back and for to read it but can just look up at a big screen )

    I believe most people in the west use Connelly's book "Machine Tool Reconditioning" as their guide. In this book, in the section for reconditioning a V-way/Flat guide like this, he recommends beginning with the flat way which is then used as the datum to scrape the V way parallel. Although your methods have been wonderfully ingenious, it seems it may have been simpler to begin with the flat way? I am sure you considered this, I am interested in your reasoning to start with the V-way.

From the correct geometry of the strip already made using a level, it is possible to make a straight edge of the corresponding length, and from the straight edge a wedge-shaped prism. The parallelism of both can be controlled again using a level. But such a method will require more work, and the accuracy will be lower.

      A micron is just a thousandths of a millimeter, and is much more common than "thousandths" which is only used for an inch. In fact, you probably own several "micrometers" which were named because they could measure to a thousandths.
      Although not "accurate", for getting a fast idea of the level of precision, think of a micron as half a tenth.
