    Thanks for another great video. I used to work for Cushman Chuck in Hartford CT in the 80's. All of their chucks were assembled with moly disulfide grease.

    Wow. What a great detailed video. I think after 40 years + my southbend chuck should probably be serviced. Really, really appreciate it. I am primarily working in brass so it has not gotten too dirty over the years. But I need to clean it up. Thanks a bunch.

    I bet you couldn't even hear that cricket in the background, but your mike picked it up loud and clear. Can't edit that sound out, but it's OK. Kinda adds a homey touch. Thanks for this video. I think my 3-Jaw is about ready for a clean out and this truly helps.

  • @Sizukun1
    @Sizukun1 ปีที่แล้ว +14

    My vote would be for grease: it'll last longer and give just as much lubricity and rust protection, and is thicker to stay where it should stay. I think oil is too thin to hold onto the chips making it feel like grease attract chips more whereas force just slings chips away with oil.

  • @rocketscience777999
    @rocketscience777999 ปีที่แล้ว +4

    Great video. I always wondered how a chuck worked. Most of it is fairly common gear grinding, but they probably had to create a custom grinding machine that could grind the presumably hardened scroll. By the way, tungsten disulfide grease has a lower coefficient of friction than molybdenum disulfide, but both will work well. Its probably overkill for the chuck, but in the world of gas turbines and rocket engine turbopumps, using a specialized process that bakes on the tungsten disulfie would last the longest, have the lowest friction, retain less chips in the moving parts, and would be less than .0001 inches thick (probably way more info than you wanted though).

    When I bought my Craftsman (Atlas) lathe the three jaw chuck was like new but lacked the pinion. I contacted the company and was told there were no parts available. After much pondering I noticed how much the pinion hole resembled a drill chuck key. I found a key that matched closely enough to work. I removed the cross pin handle and used it that way for many years although it really was not safe with the body of the chuck key protruding from the chuck periphery!

  • @TheUncleRuckus
    @TheUncleRuckus ปีที่แล้ว +3

    I used to use oil but I switched around 15 years ago after a suggestion from a friend.
    Now I use a Dry Moly Lube spray that has Graphite in it when I service the 4 jaw self-centering scroll chuck I use at work and on the one that I have on my South Bend lathe at home, which works quite well.
    Since switching I've found that I can go longer in between services bc the dry lube doesn't attract and hold chips & grit like oil and grease does, so there's less chance of jamming and wearing of parts. Also it's a lot easier and quicker to apply an even coat to the parts and best of all I no longer have to worry about the chucks spitting oil at me for a week or so after servicing like I did with oil lol. So for me it's a win win in my book.

  • @paulhunt598
    @paulhunt598 ปีที่แล้ว +1

    We greased our chucks in the industrial production shop. We used an extremely high quality grease with high tackifiers. This reduced how much grease was slung out by centrifugal force. High quality industrial chuck manufacturers usually specified the preferred grease. Once settled on a shop standard, chuck grease was universally applied throughout the shop regardless of chuck maker. Grease suppliers changed over the years, but usually we used a dark gray grease that probably was high lithium base. If you use flood coolant I suggest that you look for a grease with high moisture resistance. CNC spindle speeds normally well exceed the hobby lathe spindle speeds so centrifugal sling out is less of a problem in the home shop. Over greasing or oiling will likely give you a lubrication spatter pattern on your shirt, the lathe bed and wall behind the machine.

It would be different if you had a family member that was passionate about machinist work… but if you don’t… get rid of it all. Leave nothing for others to have to deal with. It’s a massive headache for grieving family to have to deal with such a hoard. You’re doing the right thing. Cheers Pete.

    Just took my 6 inch chuck from my South Bend 9A apart today.....
    a bit more complicated, as it has 3 slots for the chuck key.....
    lots of very old grease, but next to no wear.....the nice thing is, it has reversible jaws
    I think it was an after market addition, as the lathe is 1950's era...
    .I am debating using white lithium grease or oil now....hmmmm....
    it is 1 1/2 by 8 ...but Plan on using on my 1 7/8 by 8 ....13 " SB....mounted to a 4 jaw...
    as the 9A has never been set up......Cheers Lyle,

    I recently rebuilt my 12” Cushman because it was stuck together from old grease. I was very well preserved by the previous owner but with the tight tolerances and glue like grease it was near impossible to disassemble. I put it back together with oil which by the way if you are going to do this Mr. Pete is very much correct on the striped left shoulder. But it does work very smooth and I believe for my use the oil will work well. In a constant shop use environment grease is probably superior. Thanks again for another great video.

  • @DavidHerscher

    I like to use oil. I’ve tried both, and every time I’ve slathered it with grease i feel like I’ve regretted it. Oil will sling when the chuck gets to spinning, but it’s better than the grease i think.

    I took apart a Burnerd 3-jaw chuck and could not get it back together again; the clearances were too tight. Had to get someone with finer sensibilities to get the scroll plate back into the body without damage. It’s all good now. I have a few Yankee screwdrivers that keep on going even when the power is out - true “green” machines.

  • @robert574
    @robert574 ปีที่แล้ว

    Had to chuckle a little when you talked about cleaning it again after the scotchbrite considering what it looked like when you took it apart. Of course there may be some abrasive from the final sanding. Kinda made me want to go get one of my chucks and slide it out there so you could do it too while I watched. No doubt mine needs cleaning. I'll probably have to settle for regular diesel fuel. Did anyone else besides me think that the little bevel gear looked exactly like a drill chuck key? It even had the little tip to hold it.

  • @johnhawkinson
    @johnhawkinson ปีที่แล้ว +2

    I'd speculate that oil versus grease depends on how frequently you're willing to tear down the chuck for servicing, since you can [kind-of] add oil without full disassembly. What to the manufacturers of comparable 3-jaw chucks (without grease fittings) recommend? Surely there is some guidance, even if we don't know who manufactured this particular chuck.

    • @charlesvanvalkenburg7592
      @charlesvanvalkenburg7592 ปีที่แล้ว +2

      In a shop where the lathe is in daily use a monthly service and maintenance schedule is the way to go. But. In a shop where the lathe is only used occasionally I would recommend service after every 160 to 172 hours of use. I know that means keeping a log of machine hours which many of find inconvenient. But a little inconvenience is worth while to keep your tools and machinery in good working order.

  • @carrollprice1213
    @carrollprice1213 7 หลายเดือนก่อน

    Dry Graphite in spray cans seems to work well as a chuck lubricate due to it coating and lubricating the metal without attracting chips, etc. It comes out of the can as a liquid due to a carrier something like Brakeclean that quickly evaporates, leaving a coat of fine graphite that appears to go into the grain of metal. There are probably several brands available, but "Blaster" brand from Ace Hardware is the one I used.

  • @jossfitzsimons
    @jossfitzsimons ปีที่แล้ว

    I'd go for the motorcycle black used to put a motorcycle grease that comes in a broad tin which is heated up to immerse the chain in. It repels grit while lubricating with graphite in a matrix of grease. Maybe a motorcycle shop would you some.

    Because of all the chips that obviously accumulated, I believe oil is the way to go. While grease will last in place much longer, all the chips that get in will stick to the grease and act as an abrasive. I suppose cleaning and lubricating every so often will extend the life.
