Small note. After cleaning things in an ultrasonic like that, you need to flush with spotlessly clean water afterwards, give them a spin, and do it again. Ultrasonics loosen particulate, not flush it. So, for it to be spotless you need to flush it.

[@dazaspc]

If you ever do the job again a few tips. I spent 30 years doing machine tool maintenance so I can help with a few ideas. Bearings For the spindle it would be using Super Precision bearings. Matched sets are a thing but only when used together never separated like your spindle. They will work but shouldn't be used in your application. They can often be quite a bit out and are sold as a matched pair due to a failed production process. They are just matched to be parallel. If you look up the bearing number in a bearing book or I suppose these days online you will find the optimum volume of grease every type and configuration needs in a bearing manufacturers optimized fill. Try SKF for a great starting point. Grease volumes can change between bearing manufacturers but the difference is minimal. If you ever have them completely clean and dry don't spin them unless you have at least added some grease. Put the grease into the gaps between rolling elements. I normally use a small cable tie to push it into the area before any spinning is done. Then when filled with the prescribed volume as per the bearing guide slowly spin them to distribute the grease. NBU-15 has been the defacto standard for spindles ever since the 80's but there are other types that you wont need your entire arm to buy now that will work just as well and last much longer. With smaller bearings like your lathe has they can benefit from a thicker grease. Worth asking about from your bearing supplier as when you give them the speed and heat you will be encountering they can go by chart for suitability. NBU-15 I have used in 1 meter diameter bearings running at 2000 rpm so it is quite light for smaller applications. It also doesn't like heat or water, steam especially and breaks down fast. it also has a limited life span as even the tins have a 2 year use by date as it starts to break down. If you have oil in your tube or tin of NBU-15 it's done. Also a heads up with the tapered pin in the lead screw. It is in there as a shear pin so a hardened steel pin isn't really the best to use. Brass would be the best as it should shear without doing to much damage in a crash. Hollow as with a hole through the center is even better. However you were correct as the Spring or Roll pin you removed should never be used as they are hardened and will to more damage if ever broken. They are made for locking only. Cheers

[@dazaspc]

@@stanstevens3783 An alloy pin is ok but can run into a couple of problems. Long term corrosion can be an issue. I have seen them used a few times mostly in tool changers but if the start to rot it can be a pain to service. If brass is to strong drill a hole in it. Also if the shear is to weak it can cause problems during normal use. Think of the lead screw stopping mid screw cut. Trashes the part, tool and pride when you need to call the customer lol.

They ways were heavily worn near the chuck, and the headstock bearings were shot. When I went looking for replacement headstock bearings, the sticker shock was truly soul crushing. The price of the first bearing was 1200$ (what I paid for the whole lathe) - and the other bearing was $800. I couldnt bear to spend another 2k to make it "almost" useable, so it collected dust in my garage for ten years while I saved up for whole new machine. - And now it collects dust in someone Else's garage.

If I understand correctly (from my investigation into refurbishing my Bridgeport mill spindle)...

when installing big high precision bearings unsually you have to adjust the roller clearance. It goes like this: you tighten the bearing nut slightly and spin the spindle back and forth, then measure the clearance on the highest point with a feeler gauge, then repeat until the clearance is in spec. but the bearings are covered so you can't get in with the feeler gauge.

[@ChatNoirLe]

Those matched multiple bearings are when placed directly against each other, mount shoulder to bearing surface matched so that each bearing carries the same load, since you have a spacer between them it's not required, instead the spacer length sets the preload, so new bearings might require spacer length adjustment.

14:28 That is just the coolest gauge ever!

[@thorwaldjohanson2526]

Do you have any idea how that works?

[@mrimmortal1579]

@@thorwaldjohanson2526 it almost looks like the gauge is operated with air pressure created by the spinning shaft of the lathe. If that’s the case, what a simple yet genius way of doing it!

[@rsxinnovations]

​@thorwaldjohanson2526 if it's the same setup as an actual hardinge lathe, it's far from complicated. The two belts he put on ride on sliding pulley sheaves. The speed changer moves up and down and gives infinitely variable speeds. That gauge is just a window. The white/silver piece is just sitting on a 1/16 inch wire/rod attached to the pulley mechanism below. Look up Hardinge belt on youtube, and you'll see how the speed changer works. This lathe is quite a bit newer than mine, mine is an original hardinge HLV from 1956, and the technology never changed to my understanding.

[@MikeBaxterABC]

13:25 Bonus!! .. New belts before the old ones shredded!! .. that's maintenance extraordinaire!!! :) Side note .. I have no idea how lining-up marks on bearing pairs, (especially from two different countries) makes them more accurate, and i know a little bit about bearings ...

I was not expecting that heat gun to warm up the headstock casting enough that you could just slide the bearings in.

As many others have said the taper pin should be brass, not hardened steel. It stops severe head crashes. Learned that on my Smithy lathe mill drill. Bought the material from the local hobby shop.

I had a friend who was operated a precession grinding shop. His advice on lathe bearings was, 'I don't trust ball bearings. The most accurate lathe I ever used had plain bearings and it was the only one in the shop. I could always get more accuracy than the other guys in the shop doing the same job. There is always some side play in a ball bearing after it's run for some time. A well designed plain bearing will do better.'

[@bogeydope3022]

Only if you run the spindle pretty slowly, at around 1400 rpm max. They are also very hard to get right and replacement is a pain. Always needs clean oil and needs a long warmup procedure. This is nothing for the everyday job considering other options that are almost as good.

[@bogeydope3022]

@@keithstudly6071 It all depends on what he is doing with the machine. If re runs bigger parts that need slow spindle speeds no problem. However, i need around 2500 rpm all the time, no machine with plain bearings is gonna run that fast! Also, carbide tooling isn't gonna run great that slow, you would need to sharpen the inserts, otherwise its back to HSS.

I've been watching your videos for a while now and I just want to thank you for not only having subtitles, but decent descriptive ones as well. Not just "(metal clanking)" but "(hex key clinking)" and "(hex key scraping)" just before that as examples. As someone with auditory processing issues as well as a chronic hearing reduction issue, I always appreciate being able to watch a video without my neighbours having to hear it too. So... Thank you.

i appreciate the humour in your videos. it's just enough to make me smirk a bit from time to time and make it more enjoyable, while being subtle enough not to be overwhelming and annoying.

[@tolydukhovny682]

a couple of words of mechanical wisdom -- it is a bad idea to flush bearins in water, for they ought to be flushed in kerosene only. it is not the way to to prelube bearings by schmearing the lubricant . you should warm the bearing up, and let the lube melt and flow in. tapered pins are not heat treated as you have done it. tapered pins are lightly cemented in a gas carburiser. your troubleshooting is excellent. thanks for the video.

[@RyanRadford-k6d]

Gotta be honest, I'm really hoping the short intro isn't gonna keep replacing the long one, I love the long one SO much

[@austinXonXfire]

The bearings were discolored because of the HEAT in the ultrasonic cleaner!! Don’t ever use the heater feature when cleaning with degreasers or any chemicals really. It will strip any nickel, chrome, zinc etc etc plating right off of it :( Ask me how I know😭😭🤣🤣

[@kevkingofthesea]

If the cleaner gets hot enough to discolor the metal on its own, then it would also boil off any water in the tank. It's more likely a combination of the chemical and the cavitation (the mechanism by which the ultrasonic cleaner works) that caused the bearing to discolor. The heat might speed up any discoloration caused by the chemicals, but if it's going to discolor at 50°C, it will discolor at 20°C, just more slowly.

[@austinXonXfire]

@@kevkingofthesea I can assure you that it is the heat. You just confirmed it. The same thing happening using no-heat would probably take an illogical amount of time in the cleaner.

[@Sak-zo1ui]

If the ultrasonic cleaner is hurting the bearings the bearings are no longer good. Discoloration would have come from the detergents inside the cleaner. The oxides formed will easily brush off or can be cleaned off. Bearings are not plated generally. Especially bearings of these type. They are made alloys you mentioned. Not plated.

[@shademe]

My 1st watch of the channel. I couldn't stop, nice editing lol! I'm subscribed now. The wife fits well into this and your relationship made me smile. Thank you for your time and sharing!

[@LikeFactoryMade]

I have to admit, I was not expecting you to remove the bearings with a hammer, even if it was a rubber one. And once you decided to reuse the bearings, I would have not expected you to clean them in the ultrasonic cleaner. I think it might be just a matter of time until you really need new bearings :/ I am in the same stage with my lathe and I was wondering how to dilate the inner races enough so that they slip on the spindle shaft. I was not expecting a blower heat gun to do the trick. But IMHO, I don't think its such a good idea to blow them, you also have dust in the air that you blow into the bearings..

[@paradiselost9946]

i think he is demonstrating humility... he doesnt have to include those SMH moments... like hardening that tapered shear pin... but, considering the freeplay he measured, was assuming the bearings to be rooted... so hammer away. i was wincing myself... no puller? i prefer these videos... not all perfect. a standard lightbulb gets pretty toasty in a tin can... how any watts you got? and a radiant heat is nicer than a blast of hot air..

Sorry fella, you junked those bearings, they might hold up for a bit but precision bearing pairs should be silent in operation, sorry to be the bearer of bad news but your ultrasonic wrecked em, a plastic tub with paraffin would have done the job more than adequately.

[@freemanjackmsiradio]

@@shootgp Should your bearings need replacing, I once had to repair a Shenk 3 plane dynamic balancing machine whose main rear bearing had failed after a very short service, these were thousands per bearing at that time, I called our bearing stockist and the numbers cross referenced to a common russian tractor wheel bearing and the SKF replacements were under 250 bucks for a matched pair and outlived the shenk ones by years. IMHO a bearing is a bearing is a bearing unless you need accuracies in the millionths of an inch rather than just hundred thousandths.

I do love the thought that in about a year, after all of the teardown and rebuilding, you will realize that you were basically gifted more of a lathe housing than a lathe. And that's not as much of a smart-assed comment as it sounds. I too have nerd brain, and it seems that the getting into every nook and cranny to see both its story and how things really interact is way more satisfying than actually using the thing.
