I shared your work with Inheritance Machining who has 300k plus subscribers. I hope you will get some subscribers from this. You deserve much more attention.
I admire your determination; I started correcting a little wear in the dove tail of a milling machine and gave up after two days. I decided it was good enough
Number 1, will always wait for the next video from you. Number 2, A rented machine, you should be paid for your work. Number 3, You should put something in the bottom of the V so you don't damage the bottom corner of the scraper. In the last pictures you get tool marks. Number 4, A big thank you from Sweden for all these nice videos about mechanical engineering.
i have a few years of experience on a plc controlled, Taiwan made 1000 x 560 x 600 surface grinder and I can confidently say, I don't want to grind parts longer than a meter. Especially not exotic materials.
hey, this was interesting again. thanks for showing. I'm going to scrape my shaper too. I'm still working on making a straight edge. (3 plate method.) fortunately they are only 600 mm long. nothing compared to what you do respect👍🏻
I’d like to shake your hand. But I worry you will crush my hand with your grip strength! 😂 I am impressed by your work so far. I look forward to seeing this machine do some grinding.
Hello! For me this is also an intrigue, I can roughly theoretically assume what the result will be, but what will happen in fact? Very interesting! But I have super-precise optical devices for flatness control, so in fact I will provide absolutely reliable information, and technologically I will arrange its video recording in such a way that there will be no doubts about the accuracy of the measurements.
Common wisdom in western scraping is that you want 40% load bearing surface and 60% lowspots to prevent stick slip when in operation. What marking fluid do you use for scraping? Normaly a very fine amount of prussian blue pigment in oil solution is used, otherwise you can get a false bearing reading. Same goes for smearing of the marking fluid, when used with smooth surfaces. Best of luck!
Hello! Thank you for your clarifications. My horizons are different from those generally accepted in the West, so it is useful for me to receive additional information. I have a tube of blue paint for scraping, made in the USA, I tried to work with it, but I could not see the marks well. Therefore, I use my usual black pigment for artistic paint, "Mars black", this is black iron oxide, powder mixed with oil. Do not doubt, I will not deceive myself with an uneven layer of paint, I understand that this is important. In the end, I will switch to a very thin layer. But you write all the comments you can, it is useful, it gives reason to think.
Hi sir, I keep following you channel as always keep doing the great job and take your time I prefer your own voice steady the AI voice Hugs from Brazil
Since the distance of one meter is covered by my straight edge, and its flatness does not cause me any doubts, since I have carefully checked it, then a 1000 mm long mirror stand is enough for me now. When I finish the alignment, I will use a 300 mm mirror stand too, in addition to the measurements on the 1000 mm stand, since additional measurements will not interfere with the truth.
@@fabioth283 I understand this well now, by reducing the length of the stand I will make the autocollimator's response to unevenness more significant. In this case I will check the straightness more accurately.
@@fabioth283 I will do so after finishing the alignment, I already have a stand for this 300 mm long prism, and I have already carried out similar measurements with it before this repair, in order to understand the condition of the prism. A video about this has already been published earlier.

Would you do a video on what a ground level vile is? Maybe also what makes one level more useful and or accurate than another? I see one company has viles with colored fluid and lines but i see how having multiple lines would help moving towards level
I work in Romania on a coordinate measuring machine. Precision intruments always fascinated me. Your videos are pure gold. The autocollimator is a jewel...saw the Ebay advert for one, unfortunately too expensive for me as I don't have anything to do with it. Keep up the good work you are doing and Slava Ukraini !
although you get good physical condition from scraping, I'm wondering if you could use a level of automation in 'scraping' a large amount of material when the initial error is large, perhaps significantly reducing your hand scraping effort... does such a tool exist, in a useful format/cost for this work? if not, given the effort that i see you invest in your tools, perhaps making such a tool would be worth the time and cost? i have a couple of ideas about how i might approach such a tool design. always nice to see your video pop up. unlike some people, i do miss hearing "the real you"!
Hello! I don't have a good idea in this regard. I had to remove the largest layer of cast iron on the right side along the near strip, there was a smoothly rising and then smoothly decreasing hump about half a millimeter high near the edge. I had already created support pads, and I cut until I hit them with my meter-long straight edge. I cut as intensively as possible. It took me about one working day to cut off this hump and get a straight line from one support pad to another. So this event is not so labor-intensive. But, of course, your proposal is rational, only an effective method is needed.
I am really looking forward to the video's explaining how you achieve this goal. The most interesting is how you prevent the surfaces of the V ways to "rotate" along the axis of your autocollimator. Do you have information on the autocollimator you have for sale? Warm greetings to you and your family in Ukraine!! I hope you are surviving this horrible war
I have an old Bridgeport mill with a worn banana table, about 0.15 mm higher in the center, it's 1m long, I pen it with a hammer in it's back, but it wasn't enough, I think I recover like 0.03mm. I plan to flame straighten it, but I'm not sure, I'm risking to warp it laterally. I don't want to rectify it yet. Regards.
leave the flame unlit. study how a collimator works. with a mirror on a base and a laser pointer bounced back to a poster on a distant wall you can figure out the deviations. start by setting the references as the two opposite ends of the piece, then determine how the rest of the surface relates to that reference line. mark them out, then learn how to scrape. i suggest starting with a lump of scrap iron. yes, you need a basic surface plate. then as you get the feel of it, you make your straight edges. hunt scrapyards for suitable lumps of iron. or try the "3 piece lapping" method. except you then end up with two relatively useless parts... once you feel confident and can scrape something flat, then attempt the "nasty" job. once you get the "feel" for scraping, you can make a flat surface in a matter of minutes, seriously. a lot of it is being able to "read" the bluing. roughing them in is really a lot of "guesstimation"...
@@paradiselost9946 Hi, thanks for the reply, I already scraped the saddle with help of a small granite plate, ofc, I plan on scraping the table. I just wanted to reduce the months it will take me to do it, as soon I see a big granite surface close where I live I'll buy it and put it to use :D, I'll probably copy 'An Engineer's Findings' design.
@@anemac9 sometimes it pays to ruminate for a while as well :) nothing worse than scraping in a particular part using the wrong reference, then another part... then another... and having to backtrack when things arent lining up...
Since I have to make the tools for this repair myself, I’m working within the limits of what's possible. However, I have no doubts about my straight edge. I periodically check its surface by taking measurements, and the geometry of the working surface meets the highest standards. What exactly raises doubts for you? Are you questioning its ability to maintain flatness?
@@gena_bazarko disclaimer: my only metal working experience comes from a drill press. however AFAIK welding introduces material tensions, which, over time, produce far to big and unpredictable deformations. But as long as you cross-reference it often enough you should be good to go. correct me if i am wrong, good luck and слава Україні!
You scraping with too long line.also your blade no cut very well.sometime scraping is also to know how about a high points,low points and more many particulars.you are nice,but is ok just for video
I read your comment through a translator, and I answer through a translator, so some information may be lost or distorted. Do not judge strictly. I am looking for the most convenient and effective scraping method, I do not rely on generally accepted methods to a greater extent than I consider rational. I value other people's experience, but if something attracts me to do differently, I try as I consider rational. But in the end, I will demonstrate the result of my work, I have enough means for precise control of flatness, you will see everything, and there will be no reason for doubt.
Your videos are a gem, I totally love this down and dirty demonstration of precision; so rare to see honest work on UA-cam these days.
I shared your work with Inheritance Machining who has 300k plus subscribers. I hope you will get some subscribers from this. You deserve much more attention.
"Inheritance Machining" is an impressive channel, thank you! I've watched a lot of their videos before.
Excellent work Gena,looking forward to the staight edge build video.
Looking forward to the video on that straight edge build
Спасибо за все ваши видео! Очень познавательно и много деталей о которых другие не рассказывают! Здоровья вам!

You can try to check with autocollimator every 250/300mm on V slide.
