@@LaneyMachineTech Nice Video, it's well put together. Ouch on the reference to New Way being expensive for what the bearings are. We put a lot of time and effort in designing effective solutions for our customers. The precision repeatability from bearing to bearing is very critical in many of our OEM customer applications. If we were manufacturing a non precise air hockey puck, I would agree with your statement. The video shows you manufacturing a flat round bearing , our 65mm puck is $215.00 for a one-off. At larger quantities they obviously become more cost effective. Is $215 expensive for the amount of work you just put into the series of videos? Again, love the video. Great explanation of air bearings. I just take offense to the expensive comment because I see first hand the design, processes, manufacturing and testing that goes into making porous media air bearings.

@taxicamel 2 года назад

Perhaps, .....for those that have never been in any manufacturing environment. Otherwise, very impractical in many cases. The lathe, as one example, very limited use and extremely impractical. Air bearings as NOT suitable for much loading. This is very much a finishing machine. When you have the money Dan has, you can easily have three or four or more lathes ....each for a different application/need.

Yes there are a lot of us and we are wandering around looking for quality content. That older dude's micrometer-accurate lathe and its air-bearing demonstration is a jewel.

@keithviolette5870 4 года назад

Great series! Years ago I had worked at Precitech, ABTech and for a while Dover. All three make air bearings. I have some air bearings left over (they were getting tossed) and I have been meaning to assemble them into a little lathe for years. Finding the time is always the issue. I'll certainly be following along with this new series of videos! Keep up the great work!

@PiotrSarnacki 4 года назад

That sounds so awesome. One of my interests is achieving a very high accuracy on a limited budget. That's why I recently learned scraping and I'd like to experiment with building some stuff that incorporates scraping in the process - the beauty of it is that after machining on a relatively decent machine you literally need only hand tools to make a very flat plane on your surfaces. But cast iron and scraping can get you only so far. I'm still not done with almost any of my projects and plans, but I'm pretty sure that when I go more into the precision land I will want to look at air bairings. So thanks for sharing your work on this!

@LaneyMachineTech 4 года назад

@OAV ® Air Bearing Thanks for the support! I want to say that I really appreciate all the design info, performance data, models and prints you provide on your website. I would be grateful for a bearing to which I can compare my shop-made version. My initial design is a simple flat round bearing with a 1" diameter bearing surface. Would you be willing to send over one of your 25mm models for comparison? How can I get a hold of you?

@Texicles 4 года назад

Seeing some of the recent youtuber discussions of air bearings, I immediately thought about the Dan Gelbart machine. Inexpensive ways and shop-made bearings get us closer to this being a project theoretically possible for dedicated home shop guys, but there's one huge sticking point and I'm hoping to see you (or someone) address this challenge. Referencing the ways. Even if you buy fully finished granite parallels, I can't think of a way to ensure the whole assembly is coplanar and square without a surface plate larger than the machine you intend to build. A way to do this that doesn't involve the money and space required for a giant surface plate is the real technical challenge of a project like this

Thanks for the great video. That Oak Ridge paper is worth the price of admission. (Well, it would be it there were a price.) It tells you everything you need to design and construct your own spindle. Their six inch diameter (with 12 inch bearings) can carry a load of 500 pounds. It might be interesting to build lathe with a two or three inch spindle. Ken

@miningbruno 4 года назад

Adam is still alive! Whatever happened to those "grinding lathe tools" series (it had only 2-3 parts released, out of 5)?

@LaneyMachineTech 4 года назад

I decided to drop the video series for a couple reasons: 1) I originally started the series to help students with the tool grinding project which is part of the curriculum in my machine technology classes. The first two videos had an enormously positive impact on student success and basically accomplished the desired result. I thought the time I would spend making the rest of the videos in the series would have had a relatively small return on investment. 2) The videos were not very popular on RU-vid. I attribute this to the large number of competing videos on tool grinding which already exist. Many of them are good and some of them are superb. Maybe, if there's a sufficient revival of interest in the video series, I'll go back and complete the other videos. But I think my time will be better spent on other projects. I apologize to folks who were waiting for the rest of the series! - Adam

@Ottmar555 4 года назад

@@LaneyMachineTech What are your plans for future videos?

@LaneyMachineTech 4 года назад

Ottmar555 Well, I think I will at least finish this air bearing series and hopefully keep the ultra high precision lathe as an ongoing project. There are a lot of fun topics to discuss in the realm of precision machine design, like rigid body kinematics as it applies to the design of machine tool guideways. I have some project-based videos I'm working on which are intended for new machine technology students and cover the basics of machine tool operation (conventional mill and lathe) and inspecting GD&T controls. I also have some side projects which I think people might enjoy, including making the aerodynamic thrust bearing I demo'd in this video, making cheap DIY monochromatic light sources for interferometry, more on steel metallurgy and metallography using a light microscope, building inexpensive Arduino-based metalcutting CNC machines, building and using a dynamic balancing machine with low-cost MEMS accelerometers, and the properties of superconducting materials. I also don't want to abandon the industrial maintenance topics and I would like to make videos on mechanical seals, hydraulics for pumping and water distribution systems, lubrication, etc. How much of this will I actually be able to do? I don't know. I guess it all depends on my time constraints and the interest out there in RU-vid land.

@JlerchTampa 4 года назад

Your series is perfect timing! I recently picked up a nearly free Brown and Sharpe CMM with no electronics and all the hoses rotted off. After spending way too long researching the 'right' air line hoses and just using super cheap vinyl hose form the hardware store I've got the air bearing working again, now I just need a use for it. Turning it back into a DIY CMM seems obvious, adding a laser and a 3d printer extruder also seems logical, but adding a small spindle seems like a great / bad idea that I'm considering.

@LaneyMachineTech 4 года назад

You should make a video about it! I'd totally watch a CMM-to-Machine Tool conversion video. (Was it a Microval?)

@Scoobyvroom 4 года назад

I used to work for the company Professional Instruments Company. I made and balanced alot of spindles, air pads, and custom bearings. Let me know if you have any questions. I will say that one of the patents is the groove compensated airbearings. Their idea of precision is unfathomable to most. I ground parts that where 36" long and hollow for Zeiss CMMs. With a tolerance of cyclindricity of .00005. That means run-out no more the 50 millonths, and size within 50 millionths. They do amazing stuff.
