@@CuttingEdgeEngineering I would have used a sealed bearing to replace the bad one, rather than another shielded bearing. I bet that black belt dust got down into the bearing and that's why it's bad; because a shielded bearing is not quite as closed up as a sealed bearing.

[@m2hmghb]

It's a heck of a lot cheaper to replace some bearings then it is to repair the excess damage done to other parts because of the bearing failing. Timing is always the problem - you don't want to jump on it too fast when it's still working fine, but if you wait for it to completely fail you risk damage to other parts. Great video!

that's the truth, after seeing the inside and how dirty it all was and burnt grease it was good to give it a birthday!

[@dikkiedik53]

In 1966 I was 13 yrs of age when I didn't know what to do with my future. My neighbor took me with him to the electrotechnical company where he was head mechanic of the department for rebuilding electric motors. It was the time factories had a 2 week summer standstill for servicing all the motors. From 0.75 kW to 200 kW. So it was busy in the shop and in no time I was busy taking electric motors and the attached gearboxes apart, cleaning them, renewing bearings etc. They taught me every thing about electric motors. I wasn't even legally allowed to work! I saw it just as a thing to be busy during summer holidays. When I had to go back to school he came to me and gave me the pay of a mechanic for those weeks. He told me I earned every cent of it. The next year I worked there too during vacation. After that vacation I entered the practicum for electrotechnical engineering at school for the first time and the teacher asked me what I thought of the it. I pointed out to him all the different types of motors he had there with all the specialties of them. He got a bit pale around his nose and told me he had 2 years to to teach me what I already knew. You brought me back to those years... thanks!

@@CuttingEdgeEngineering Well, guarantee the grease you put back was a lot more quality than the original, and you probably got all of the grit from the original casting out as well. Had that, take it apart for service and chunks of the sand from the casting was still in there, right next to the 1S bearings that were noisy. Sand all got moved, cleaned, and the new 2RS bearings went, in minus the one side seal, so the oil fitting could still work. then it got a nice fill of synthetic oil to make them happy. Original was something akin to road tar mixed with gravel....

What a great reminder of a job I did myself about fifteen years ago. "The same bearing sound" isn't a bad thing, and it's always good to begin again with new bearings and an actual installation date recorded. We easily forget the time and frustration of doing so with the years of no trouble that come after.

[@capnkwick4286]

My dad was a WW2 aircraft mechanic and one thing he impressed on us when working on the farm equipment was to always use something else between the hammer and the bearing. For bearings up to 2 1/2 bananas (63.5 mm) we would use a socket that fit over the bearing race. For really large bearings we would use a block of wood in place of the socket. And that little "pop" when pulling using a gear puller is always so satisfying.

[@TradinTigerJohn]

Hafco have evidently put some very nice effort into building a quality milling machine as evidenced by the overall build quality you uncovered as well as nice details like balancing gears that they could arguably have gotten by with if they'd left imbalances few would notice. But you also added significant value to your own machine by installing better suited-to- purpose sealed ball bearing assemblies, by using polymer composite grease in the main gear case and by scribing the precision visual guideline as a visual rotational axis cross-check. Hafco cut (or spec'd) that top drive gear set "off the involute" to give it more robustness at the expense of gear noise. This also let them specify harder (but more brittle) gears there for better long-term wear characteristics also at the expense of noise. But the machine sure sounds sweeter than it did, and I'm confident you postponed any major maintenance on that machine by hundreds, if not a few thousand, operating hours. As an old manufacturing consultant, you're a joy to watch on the shop floor. Your success as a machinist is as well-earned as your, Homeless' and Karen's work in KZbin production.

Yes, this is something I'd be scared to do. Taking complex equipment apart like this would make me highly nervous about being able to get it back together again. Curtis is braver than I am! A *LOT* braver.

Have confidence in yourself, switch the negative thoughts off. It is a series of small jobs that make a complete job, take your time, one step at a time. Having experience obviously helps. But in my experience it always works out no matter how deep a hole you are in.

[@brand-x7049]

Honestly, it sounded a =lot= better after going back together - before, I couldn't even hear the gear noise for all the other dry-bearing racket.

[@scoobtoober2975]

Some lads that worked for a few bearing companies told me to chill bearings with dry ice and alcohol if you can't get a hold of liquid nitrogen. Worked a treat on some Subaru wheel bearings. Cheers Love your work

Preventative maintenance can seem like a bit of waste of time but if definitely isn't. If it was done more often maybe your shop would be a little less busy!😉 Happy Friday - Thankyou K, K & H 👍

So awesome to have this on video. Not only for reassembly for yourself if you needed it, but will probably end up being an invaluable resource for someone else somewhere in the world. Keep making chips!!

[@libsrdum]

Maintenance, the unsung hero of every company. How on earth did you keep track of all of those parts? You could do a whole video on that. Again, Karen's video skills were excellent. As for me, I was impressed that not once did I hear you say, "Karen, hand me that wrench.".

[@ellieprice363]

Take clear photos of each assembly before taking it apart. Photos have been invaluable to me during reassembly many times.

[@quintrankid8045]

"How on earth did you keep track of all of those parts?" This is what I wanted to know too.

Always recall the forklift driver who left the company and got a new job. However one of his key jobs was greasing the machines in the morning. 2 months after he left there was 100k of scrap produced when the fixtures became worn…..

When you got deep into the disassembly it started getting quite complex and involved. I'm glad you managed to get it all sorted out with no issues. The design of the mechanical speed control was interesting.

One might think that split pully enabling the variable speed is a new innovation but it's rather old. I have a 1964 john deere garden tractor I rebuilt and it has that design to give a range of speed for each gear

[@garyprice8490]

Great videos!! You are very methodical and thorough. You were right in replacing those bearings. From my experience the 2nd source of noise is the backlash in the gears. You may want to check them and see how much out of spec they are. I replaced the bearings in a Bridgeport and had the same thing happening quieter but still loud. I then check the clearances on the gears themselves and they were way out of spec. I had a frien that had a brand new head that was damaged in shipping years ago and offered them to me. We got them off I replaced them with the newer ones given to me. It was a very quiet mill! Success was sweet.

[@tantamounted]

4:40 I'm glad to see your safety officer doing a proper job of it. It's good to have family who care about your well being.

[@brendanroberts2032]

As soon as I saw the gears I knew you were never going to be able to make it quiet for very long. My old Van Norman mill has a 3 speed box with straight cut gears and there isn’t an oil on the planet with a heavy enough weight to keep it from howling. Great video! I have Mill envy!

[@Stefan_Kawalec]

Kurtis did what he did, as usual. But Karen, you did an amazing job with sound. Hearing all those mechanical nuances is so satisfying. Thank you. BTW, HafCo should pay you for that. The video really shows how well those machines are made.

[@jasonhache389]

in my experience manual milling machines are always noisy, so i would say people that think it is noisy have zero experience running them. i am a veteran of the machining world manual and computer controlled., with that being said i admire your channel. thank you for the excellent content.

[@ThePhoenixAscendant]

Curtis, as much as I love your various videos of you repairing other people's equipment, I have to say there's something surprisingly satisfying about watching you do a shop infrastructure video... especially seeing and hearing the finished product... absolutely beautiful. Best wishes to you, Karen, and Homie in the holiday season and in the new year!

[@prometheus42472a]

As always... loved the video. you're a brave man pulling that all apart yourself but I imagine that saved a boatload of money doing it yourself. The "BANG" @42:03 and accompanying camera jump was effing hilarious! Thanks for the laugh!

[@danieledwards1081]

Yep, that bang was comedy gold, I get my Mrs with that all the time 🤣🤣🤣

[@wpo2949]

A shout out to Kurtis here... I work for an Engineering company in England and we recently got hold of a 1990's 'Manford' milling machine that looks to have only ever had light use. It's basically the same as the mill that he is taking apart here. The speed control on our machine was unresponsive and partly seized up. I thought it could be quite serious but it turned out to be in need of some fairly basic servicing. Because of this video I'm now well clued up on what goes on in the head of our milling machine..! These type of mills are basically another 'Bridgeport like' machine but are important because they 'look' slightly heavier duty and are basically newer. He's obviously put effort to get his best message across about what goes on inside a machine like this ... Nice one Kurtis...

[@proimsat]

I just love those satisfying clicks the bolts make when they come undone. The filming quality and timing just gets better and better over time and it's so amazing to see!

[@sawboneiomc8809]

Those 3 prong bearing pullers I always found it troublesome to keep the prongs separated wile I tighten down the screw. I found if I put a piece of shop rag between the prongs it gives it enough resistance/springiness to keep them apart till the screw is tight. Especially when it’s horizontal and not vertical. Then it’s easy enough to pull the rag out once it’s tight. A tip I found works really well. Maybe someone else out there can use it.

[@CuttingEdgeEngineering]

good tip thanks for sharing mate

[@Rogster559]

I was absolutely enthralled watching you pull your machine apart and maintain it, I like to follow the policy a good operator maintains and knows his machinery inside out and doesn’t have to rely on others to fix small to medium size problems the larger problems may need a specialist to fix it , some one like you Kurtis your attention to detail is above and beyond anything I have ever seen and the same goes for Karen and her filming and editing , thank you from Tassie

[@herpderp264]

As a tip, in the future if you need to rebuild the head of them. Just take the four bolts loose that hold the head to the ram assembly. We had a few machines go out for rebuilds at the shop I used to work at, and that is the beauty of bridgeport style heads. Four bolts, and you can take them off. If you want them mounted vertically, just set up an angle plate on a bench and you can keep it vertical. While obviously this is hindsight for you, it is something to remember in the future in case you need to pull the head off again.

[@pawz007]

🤔 he did take those bolts out. How is that a tip?

[@chucksmalfus9623]

@@pawz007the tip is he didn’t need to remove the ram just remove the 4 bolts holding the head to the ram , the 4 bolts in the front, and leave the ram on the base.
