- How to Clean your Lathe chuck. Cleaning and Lubricating of your lathe chucks is very important for long life and maintained accuracy. I was getting ready to put the 10 inch 3 Jaw scroll chuck back on the Lance Lathe. Since I have never cleaned it I figured it was a good time. So I do a complete disassembly, cleaning and reassembly.

Thanks Randy, I need to service my chuck and having never done it before your video is very useful. Keep the videos coming, Cheers from Australia
Thank you Doug. Not to difficult, but needs to be done.
Reminds me that i cleaned my 125mm Chuck just a week ago - Looked like yours on the inside :D
Stefan Gotteswinter My chuck has about a 14mm gap between the adapter plate and the chuck, fills with Swarf and everything else. Thanks for watching, Randy
This is what i have been waiting for, The 3 jaw chuck. Thank you.
Randall Moore Just a clean up. Thanks Randy
Thanks for showing this subject. I won't be afraid to clean mine now. Thanks!
Herb Blair Thanks Herb, Have No Fear. Thanks, Randy
Good to see the correct tools for a given task being used properly. Take care, be safe!
***** I was putting the screwdriver in a slot and turning. Thanks Randy
Wow Randy that was pretty gunked up. No doubt with your perfectionist it will be running much sweeter.
Never had one of them apart man , Great info !!
ShawnMrFixit Lee Not to hard, thanks for watching. Randy
Thanks, very informative! I need to do this
Good deal. Thanks
Enjoyed the vid Randy and the display of Snap on tools, flex head torque wrench is sweet!
outsidescrewball Thanks Chuck. I love that wrench. Randy
Randy, love the 3/8" speed handle (with a knob), have had two in forty years. Used with a universal socket, you have an extremely long (high torque) wrench.
Joe Rogers I have several of different lengths. They are very useful on aircraft for use on Phillips head screws, by the 100's. Very good tool for a stuck or difficult Phillips head screw, you can apply a lot of pressure. Thanks Randy
Hi Randy,
This video was very informative. Nice to know how a 3-jaw chuck comes apart and goes back together. I was surprised by how much gunk was under the back plate. I would have thought the close tolerances on the flat surfaces would keep that stuff out.
Thanks,
-mike
***** Thank you Mike. I am glad you found this helpful. Between the Mounting plate and the chuck there is about 1/2" gap. That is the fist plate I removed. So that space can really build up. The internals of the chuck were not to bad, but I doubt if had ever been apart. Thanks Randy
Good job
pancho villa Thanks Pancho. Randy
sweet job
+Mert Silliker Thank you, this is a fun kind of job.
Hey Randy,
A clean chuck is a happy chuck! Phil and I are making a precision grinding fixture for my 3 jaw, I figure since I had my head trammed in I would try and get out that 3 thou run out on my chuck by grinding the jaws. You are welcome to it if it works :)
Thanks,
Ray
Ray Caniglia sounds like a good idea. Are you going to wait until the temps are bit more constant and not up and down so much?
If it works, I will be looking to do that. Thanks. Randy
Nice video---------------thanks
Tom Bellus Thanks for watching Tom. Randy
Hi Randy
I'm doing a Cushman 8" chuck for my dividing head. Oh what a bunch of rust and crud. I'm using Evapo Rust for rust removal. Doing well, so far. Waiting for one more part to soak overnight.
Thanks for the video.
John
John Bazaar The chuck should clean up well. Thanks Randy
randy nice chuck clean.
Robert Kutz Works very smooth now, Thanks Randy
Good video, I've never seen a flex torque wrench that looks useful
Eric Corse Thanks Eric. Very much so on aircraft. You use a torque on so many things in tight and hard to reach spots. Thanks Randy
Thanks for showing how to dismantle a 3 jaw chuck. Need to do mine. Been meaning to ask Randy mine's quit rusty can I use scotch brite to bring it back up to a shine. Or is this not recommended. Hope your keeping well buddy. Still on the mend but will keep you up to date ounce I'm ready to pop over my parts.
👍👍👍
Grate video .
Leonard Colvin Thank you Leonard. Randy
Must be something in the water Randy! Just did the same for my 3 jaw a couple of days ago! A much smaller beast that yours but just as full of crap! It was showing up as having rather more TIR than I thought it should so it got the treatment and that returned it to what I thought it should have been. Be interesting to see how yours turned out.
Mike Clayton Thanks Mike for sharing, I have not made any measurements yet but I think tomorrow I will get some quality shop time. Randy
Nice video. I like your wood work tray. Im going to have to make one of those. Very interesting choice on the lubricant. You said its low pressure, is that right?
Dale d
***** Thanks Dale. I use the try on all messy projects of if something might cause damage to my table. My table is 3/4" milamine. Yes, the gearing is low pressure. The pressure between the gear teeth is low when the gearing is in motion. The moly lube will remain between the teeth very well and takes very little for good lubrication. The spray moil would also work very well and much easier to apply. One great aspect to the moly lube is when it gets dry it still provides great lubrication. Thanks Randy
I too like the traqy and will be making one too! :D
Excellent!

arkansas13 Thanks 13, Randy
Nice bit of house cleaning. Later
NSTRAPPERHUNTER Thanks, just a bit of maintenance. Randy
Nice job Randy, I think you'll have another hour into it just cleaning your hands,,lol Take care
rchopp Thanks, yeah clean up is always time consuming. Thanks Randy
Could gasket sealer be placed in a circle around the center bore of the back plate, then mounted back to the chuck and left to set up before use? May keep the gap between the plate and chuck from getting filled up as bad.
RantingFury That would work. But I am working on making the chuck an adjustable chuck and that void would go away.
Thanks for the suggestion and for watching. Randy
Lighting on the object of many of your videos seems somewhat wanting. Otherwise I really enjoy what you do.
MoS2 (molybdenum disulfide) lube is a fashionable marketing hype. Scientific papers have clearly shown that MoS2 is only superior in absence of all moisture. I.e. in high vacuum or in dry nitrogen or Argon environment. That means in a normal shop environment you cannot benefit from its properties. In moisture however graphite and teflon powder are doing better than MoS2. So a graphite filled grease is better and cheaper too.
For this use the it works quite well. This paste dries and is very thin and provides great lubrication without being sticky and collecting debris. It is not the best lube of all situations but for scroll chucks it works well. Thank you for the great comment about MoS2 lube.
if you want a dry lubricant try dry graphite or teflon powder and rub it into the surfaces using force. Bottle corks have been proven useful as rubbing tool. For a chuck scroll this seems not practical, though.
Sometimes when you are watching videos you get stupid, too. And then it dawns on you later...that's what he was doing. Not really in this video in particular, but many a times I've been watching and have had that revalation moment. :-)
ILGopher I know what you mean Ryan, I have the same problem. Then I go to the shop and get over it. Thanks for watching Randy
Nice work Randy! I was waiting to see if any of the "Chunder"(different from Chowder) from behind that mounting plate was going to fly into your Big Ass coffee mug...looks like you moved it just in time :D
I also was kinda hoping that when the last cap screw flipped out of your hand that it was going to dive into your jar of never-seize, that would have made me laugh so hard I'd shoot carrot juice out of my nose, LOL! I felt mischievous, I know...
All jokes aside, I do have a question for you...or maybe it's two questions, we'll see. I got a 6" 4-jaw chuck that came with a backing plate that fits my Atlas, but there are two sets of hole patterns drilled into it. The one that fits the 4-jaw is a 4-bolt pattern, and there is a non-concentric 3 bolt hole pattern also drilled into the plate. Do you think that the plate, which seems to fit nicely, can still be used, or will the holes drilled in the back affect it's balance?
The other question is that I don't think the backing plate has ever had a skim cut taken from it like they advise in catalogs and parts houses, should that be my first step or should I scrap the whole plate and wait to buy a new one? I'm not sure my level of skill requires such precision ATM, but I just want to have an expert opinion. I'll be showing the stuff I received on a video tonight and will also add some pictures of the plate in question to FB too.
Sorry about the novel, it just seemed appropriate since you were working on your Bison. Mahalo and Aloha...Chuck.
If you take a skim cut, would that make the back plate undersized and sloppy? If you chucks were anything like mine, the OD size of the hub on the backplate and the ID on the back of the chuck has to be a tight fit so it registers correctly.
Nope. I'm talking about skimming the face of it, like Randy did to his face-plate. On some of the websites that advertise "blank" back adapter plates, they recommend that you take a facing cut to true up the casting.
The only ID on the chuck is the bore, and it doesn't register on anything. The 4-jaw seems to run true when it's mounted, but without two gauges to check whether or not the face runs concentric to the bore it's all just by eye.
HERE: is the type of Chuck it is: www.grizzly.com/products/6-4-Jaw-Plain-Back-Independent-Chuck/G9865
HERE is the type of adapter plate: www.grizzly.com/products/6-X-1-1-2-8-TPI-Back-Plate/T10098
Knolltop Farms I would mount the adapter plate on the lathe. Put a dial indicator on the face, check the runout. You want zero or as close as you can get. Take a facing cut to true up then recheck. When you are happy with the runout. Mount the Chuck. Chuck. Only turn the OD to match the chuck. Should then be good to go. Randy ps: i had to throw in the the Chuck.LOL
Randy Richard Depending where the chuck registers on the adapter plate you may have to true or size the register. I did not see how that was done in the photos. Randy
Randy Richard
Thanks Randy, I will make a video of it in the morning beginning with testing the run-out of the adapter plate and working from there. I will be using your face-plate video as a guide :D...Aloha, Chuck
Polski Bison?
-Pozdrawiam z Polski Paweł.
Yes, Thanks.
That's almost as bad as the Chuck that was ok my grandfathers old lathe.
Mike Dittman Thanks Mike. Randy
Hey Randy,
Some "deja vu"....Dirty back end of a Bison... lol
"Stupid" you really forced yourself to find the leanest possible word for You Tubers producing videos
I was more worried about your cup of coffee flying than you untie the screws, good idea making indexing marks
The "Zero position" can vary according to the gear that will repeat the best, could be any of the three after testing.
That was "Chip control" now evolving to "Chuck cleaning"
Have a good one,
Pierre
pierre beaudry Thanks Pierre. I thought you might like this, I almost busted out laughing while making this video. You can see that this chuck is identical to yours. I am thinking that I could make this into an adjustable chuck. After seeing yours. Just add 4 holes and some adjusting screw/rods. What do you think?
pierre beaudry Oh I just WAGed the weight. Pretty close.
Randy, you sounded a little on the frisky side...lol
As for making an adjustable chuck with you 3 jaws, is there enough room in the back bore of it to accommodate the the adjusting pins with their associated screws, you would have to make sure the adaptor plate goes at least to the adjusting pins and there is a little drawback, the tightening screws are in the back of the chuck instead of in the front...
I would say probably doable...! Pierre
P.S. That would make you as crazy as I might be... lol
BTW try to guess how much came off the back plate, originally 1.250" ( I think, not in the shop presently) thick and 12" dia.
pierre beaudry LBs' several.
