The last experiment made me curious about the curvature at the bottom of your straight edge. You could probably get a estimate by measuring how far the gauge block can be pushed under the straight edge under different deviation (measured with the 0.2um indicator). You could also measure it with an optical flat.

Thank you. I have seen mention of autocollimators (usually around maintaining large surface plates) and had only a rough idea how they worked. Thank you for providing a deeper look at one.

@Rob_65 Ай бұрын

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 Ай бұрын

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.

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.

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 Ай бұрын

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.

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 Ай бұрын

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 Ай бұрын

@@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 Ай бұрын

@@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 😀

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 Ай бұрын

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.

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.

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 .

Your presentations are enlightening and encouraging, a recipe to get it well done if only simply followed with care and attention. It is hard to imagine a process more efficient than Yours.

Excellent Grzegordz! I have already gained my first experience in repairing a guide with an autocollimator. You see, I'm working with the same as yours, 1 arc second. Already with this autocollimator you can do the job perfectly and get excellent accuracy on the guide. If you add a good camera and display the image on the monitor, the sensitivity of the device will significantly increase.

Thanks Gena, maybe You are right and 3-5 microns per meter is enough for me at the moment. My mill is also worn out at as much as around 0.1 mm on the main axis. The tricky part being that I have 45deg dovetails on table parts weighing hundreds of kilos

Can you explain ( hopefully in the next video) how you measure the actual height of A1, A2, D1 and D2 individually?

@phrozenwun 2 ай бұрын

If I did the math right (no guaranty ;-), the total out of tram vertical angle of arctan(0.26/2/300) ~= 1.48969017 arc minutes means dropping B1/B1 by about 0.43 microns. And moving back toward tram is generally a good idea. Since C1/C2 can not rise up then B1/B2 need to drop, but only if D1/D2 have an excess of greater than 0.86 microns above flat, else the whole run will need to drop and that is a lot of work, especially when it only corrects a cosine error in the vertical measurement of ~=94 nanometers per meter! Great work, thank you for sharing!
