Nice work Manuel! By the way, there is a relatively easy way to make glass or even zerodur air bearings. Instead of using diamond milling the surface channels, you can use sandblasting with SiC. Using 3d printing resin, which is relatively blast resistant, you can create the pattern and then blast ths glass surface to depths ranging from a few to a few hundred microns deep.

Thank you. Also great tip! If I ever get around building a sandblasting chamber I will try that out.

@@DiffractionLimited Fuck youtube comments everything gets filtered :( If you want you can adjust the filtering in your setting to be not so strict. But IDK if you have bot problems. (KZitem Studio -> Settings -> Community -> Defaults) Here you can set the strictness (for new videos, old one have to be adjusted manual)

I learned a lot from this video. I was planning to use same epoxy layer application, but was not so sure about if it will work or not. Thanks to you, now I know that it works ! Nice ending music btw :)

Can you do a video on that what looks to be homemade drill press? Please.
@DiffractionLimited
Күн бұрын
Yes its a homemade drill press and its unfortunately not finished yet. But I can do a short video about it in future. It uses a JMC Servomotor as spindle allowing for very silent operation with position, torque and velocity control (e.g. for tapping). It has a small esp32 microcontroller and an Oled display for showing RPM/Torque. Its really quite neat!

You just made KZitem a better place. Really nice job and very well executed and explained. Just one question tough: how much is the pressure loss and how powerfull has to be the compressor you use for the air to push into this air bearing? Thank you in advance.
@DiffractionLimited

Thank you. I use two tiny airpumps in series, which produce about 2 bar. The amount of air consumed by the pads is really low (The air within the small 1m hose is enough to keep the bearings flying for about 20s after turning off the compressor.) You can even use canned air for testing.

Nice. Next up JB weld air bearing ball joint using a ball bearing? Or making a preloaded air bearing with two sones for vacuum and air?

Do you know of any resources that a person could use to be able to calculate the specs of a bearing for a given purpose? I'd love to be able to use them for my own project, but I'm not sure how to figure out the specs that I'd need.

I think for now you would have to experiment on your own to get the specs. There will also be an open source simulator program in future, but it will take a while until it is ready for release.

What is the role of the plaster filling? Can those bearings work without it?
@DiffractionLimited

@@timbehrens9678 The plaster filling acts as a restrictor and is extremely important. The bearings will not work without them. You only want a tiny amount of air entering the gap so that the pressure collapses as soon as the gap gets slightly larger. This produces a 'stiff' bearing force.
