Let's get a thumbs up for recasting that lead hammer! 😁
Thanks for sharing Keith,
Cheers
Was gonna comment on how he needs to make a video of recasting that hammer. lol
Yup it’s way past due 😁
Its that time of the year again 😂😂
Reckon he's got a good few years left in that one 😆
That old hammer goes on the wall. Mr Rucker needs to make a new one.
The old workhorse deserves retirement. A place of honor.
Please don't melt it down. Make a new lead hammer, same or similar,
with all the knowledge, pros and cons of the last one.
"You gotta hold your mouth just right to get these back in..." LOL I used to live in Lawrenceville, GA and I haven't heard that saying since then. Thanks for the chuckle and sharing your knowledge! Cheers!
I remember my Mom telling me that when I was first learning to tie my shoes. So great to hear it again!
Here in Denmark we say it a bit different: keep the tongue right in the mouth 😄
Apprenticed in Vancouver BC 1963. I enjoyed the great practical approach you displayed on this you tube. It was also very enjoyable to watch a craftsman plying his knowledge. THANKS
LOVE to see old, rusty 'junk' made NEW again. Machines truly are eternal. Thanks Keith for a little bit of permanence in my world. CHEERS!
A little late to watch this, but timely in a way. Yesterday I watched Ca Lem on his RUclips channel make a 6 jaw scroll chuck ... from scratch! If viewers of this channel haven't seen Ca Lem's channel, it is definitely worth a look. A very gifted and humble self-taught young man.
Love Ca Lem’s stuff. Def agree
Concur, that young guy is sharp!!
Ca Lem is a very talented guy.
At first I was thinking Ca Lem was ToT’s alter ego’s channel. It was the Schaublin and just hands that threw me off I think.
Couple of notes. A Bison chuck usually has threaded holes on its backplate. When you screw bolt in there they will press the backplate off. And you don’t need to use chisel on your chuck risking to damage it.
When the backplate is off you put your screws back in (at least half of the way) an bump the whole assembly against the table. The scroll will fall off and no need to bump it with a hammer.
Otherwise a great job as usual. I doubt that you did any damage to the chuck. The comment is mostly for others who will be servicing their chucks.
This guy is not a machinist!
I have one of these as well. And it's time for it to be cleaned. Thanks for the info. I had a foggy memory that these might have holes to use jacking screws, but I wasn't sure. Thanks for the reminder!!!!
Neither am I. It doesn’t really matter if you’re love this kind of stuff
Thank you.
@@deedeeindustrialsuperprecision Keith’s bio says his original interest was woodworking. Restoring vintage machinery does not require a high level of machinist skills. His machinist skills came much later.
One advantage of a six-jaw is that you may pull two opposed front jaws to grasp rectangular and square stock.
"A little bit of light work" Do NOT let your surgeon see this video! they will be horrified!
I think actually Keith's well on the way to the end of his 2 weeks of light duty work. Just keep off the painkillers so you're fully aware if you overdo anything.
Kieth channeling his inner Bob Ross "happy trees" as he puts this chuck back together. Love it.
I don't have a metal lathe but I have multiple wood lathes. I have several three jaw chucks and am amazed at how they work. When I started out learning (on my own) how to turn I had a friend show me how to make a wooden chuck that used hose clamps for tightening. It worked pretty good. When I was able to purchase my first chuck I was thrilled. Twenty plus years I still have my wood chuck on a shelf. I love turning wood and plastic into many fun things. I have a dream of getting a small bench metal lathe and learn to make some of my own metal parts for pens, etc. Thanks for sharing. I enjoy watching your videos. In Feb of this year I had surgery on a finger whose tendon was stuck. It took a long time but finally about 99% normal. Have a great Thanksgiving and Christmas season. We all have so much to be thankful for.
Love the shop assistants. You have some quality helpers.
People think WD-40 isn't a great lubricant because it isn't a lubricant at all. It has some minor lubricating properties, but it is was originally designed to de-ice wings of planes. As a mechanic I use it almost exclusively as a cleaner for metal parts and machines.
WD works well for me as a cutting lube for Aluminium and Tellurium Copper, but I buy it by the gallon to use for dealing with condensation in my unheated and draughty machine shop on cold nights here in Yorkshire UK
I admire your taking the time to clean your tools and keeping them organized. Just one of my OCD things
This was certainly an interesting ASMR to fall asleep to last night
Nice chuck restoration. Thanks.
Glad the shop cats approve of your work.
Oh my gosh! Even Keith has to occasionally back up, rethink, and persuade parts to behave themselves. Maybe I'm not as inept as I thought. Bravo! 😉 👍🤝
I've observed that many times about Keith. He is a great teacher and model.
Of course, who among us would not be a better person if we could edit how we present ourselves to the world?
I'll never run a metal lathe but I never watch one of Keith's videos without learning something of value.
Thanks Keith. Enjoyed
Great stuff as always big guy!.
I love videos like this. I can remember sitting in my grandfather's shop, tearing things down and putting them back together..... or at least trying to stay out of his way while he tore things down and put them back together. It'll always be a toss up between WD40 and Hoppe's #9.
Excellent video of how to do this task, what an apparent overhaul of a rusty chuck. That
Evapo-Rust stuff is mighty impressive. However I'm really looking forward to seeing the final adjustments once mounted on the lathe later.
That's nice. I have a lathe from the 1800's, with all the original gears and chucks. Everything. It is in desperate need of a full restoration. My friend had it, he passed away at 87 years old just 6 weeks ago. . I would love to get it to you. I live in Ms, Lauderdale
The halves that contain the scroll can be separated way easier than using a chisel and a hammer. The three screws that held it together can be used as jack-screws to pull (actually push) the halves apart. Most precision chucks have this option to avoid deforming their internals.
I would also have soaked the poor thing in evapo-rust before trying to dismantle or operate it. Most likely less hammering.
The jaws have have a separate crown which is now held together by their screws and their rust and maybe some evapo-rust residue. It would have been a good decision to get them apart as well. And Yes, I know, they might be sitting really tight.
What a beautiful piece of machinery. Awesome restoration. Many more years of use ahead now.
Really enjoyed that Keith. My first time seeing the internal workings of these beautiful Chucks.
Nicely done, I have taken many chucks apart to clean and lube them, lightly lube them. I found from my experience that any machining of bronze or cast iron material the cleaning had to happen more frequently. Thanks for info and the video, nice to see someone restoring old iron back to usable condition.
They're not shop assistants, they're shop supervisors....
Thanks for taking the time to shoot this stuff Keith.
I appreciate it.
Thanks Keith excellent commentary to accompany your practical demo. Many thanks
I was on a CNC lathe. At some point I noticed that the chuck no longer had the jam path. At first I thought the hydraulic system had a fault, but I couldn't find the fault there. Then I tried to grease the chuck again, but that didn't help. So I said it was no longer possible. Then I was given the task of removing the chuck, disassembling it, cleaning it, relubricating it and putting everything back together again.
In a good company, the clamping pressure is measured annually. Things have flown because of it. Especially small parts with high speeds. zooonngggg .... You can hardly pull your head away in that fast.
They measure the clamping pressure annually??? sounds painful... and sort of cruel.
Joke.
Is this a Google translation - I don't understand a word of it.
Keith, another great video! I really appreciate you taking the time to explain the entire process. It turned out fantastic!
Hi Keith! Great job! I love the way Evaporust works! Great job!
Gotta Love that Evapo Rust. That stuff works Great. Great Job on the Chuck. Can’t wait to see the Lathe being restored.
Great engineering makes refurbishment easy. Great video!
Great video as always! I've been a Tool and Die maker for 30 years and You're truly a man with a craft! I'd like to meet you some day.
Cell phone camera's are great when reassembling , take lots of pictures 😎👌
Very nice video, Keith, and VERY nice score on the chuck! I had been wanting a tru-set six jaw ever since ABOM got his, but just too spendy for an old retired cop like me. Fortunately, found the chinesium version from SHARS for less than a 1000 including D1-5 cam lock back and shipping, obviously not a BISON, but will work well with light machining I do as a gunsmith. I look forward to your mounting and adjusting video in the future. Thanks for the nicely done instructional video.
That huge tank of evapo rust sure is handy!
Thank You. Keith!
consistent goodness! thanks!
Lovely job. Very satisfying 👍
Thanks for the tutorial on that refurb!! Also great to see you mentioning what "WD" stands for. Nicely done Keith!!!
Just for the record, WD-40 is mostly (>75%) mineral spirits. They have done a great job marketing the stuff!!
Thanks Keith. Good show.
Thank you for sharing. Nicely done.
OUTSTANDING, always found it good therapy to bring a piece back from the dead🤗😎🤗😎
Amazing restore!
From 'recycle for beer cans' to 'showroom ready'. Cool.
I enjoyed this. Thanks!
Great find Keith. Looks like a Bison Set-Tru!! Great Channel, thanks for the share!!
Great video, thanks Keith.
Very well done video. Thanks for sharing.
Nice chuck and a job well done, thanks for sharing your video
Thats an awesome chuck Keith. They're very expensive to purchase new. Great find.
Great job! If you leave the mounting studs out, you might be able to internally chuck on the backing plate to spin it up for polishing.
Hey Keith nice chuck, I have a self centering Bison & it is great. When washing parts & you want to get all the water out soak the parts on Methylated Spirits (Denatured Alcohol). I will absorb the water then heat with a hair drier or heat gun & the Methylated Spirits (Denatured Alcohol) will evaporate leaving your part moisture free. Same if you have water in any of your petrol (Gas) tanks. Cheers Peter from OZ
BISON CHUCK factory still worken in
north-east Poland
Nice Video. Thanks. Bison has a rebuild procedure video for these chucks on RUclips - I rebuilt mine since it had done brass chip duty (also from a prior owner's Monarch 10EE). Probably a good idea to have not too much grease but Bison's own video shows them lathering the rack gears liberally. You can purchase Bison chuck grease. Also, I find an ultrasonic cleaner with orange degreaser very useful for small parts cleaning.
Super fun. I love the video. It is much appreciated. I have the shop towels, the hex drivers, and the WD40. I guess that I need to add a few tools to my arsenal. :-) Thanks again.
Great job, Keith! Don't push the left arm too much. Docs might say a couple of weeks, but it will probably take a few more to fully heal. Love the shot of the cats. They're getting so big. And so calm. One bang in my house and all four head for cover. Yours? Eh, whatever, we want to sleep, we're going to sleep.
Bison chucks are lovely chucks! and that was a great refurbish ..With the camlockstuds, there should be a ring on the pin just below the cam cutout which is a depth guide for how far to crew it in. going all the way to the bottom of the thread is usually too far and the cams wont old the pin correctly (theres pointers on the spindle nose where the cam indicator has to land between when tight, you adjust this by screwing the pin in or out as required)
Having done many of those I have found soaking them in diesel fuel 24 to 48 hours in a warm spot with occasional stiring works very well.
Hear hear.
Yep. There are two things that work better and easier with time: soaking frozen/rusted anything in diesel - preferably in a warm place, or warm the part first, and restoring cracked and dried wood in linseed oil in the sun. Linseed oil likes to soak into end grain, just as warm diesel creeps into every tight corner.
Two things I do differently are that I wash thoroughly in hot water and washing liquid before and after de-rusting.
Then I get all the water out of the pores of all metal parts by warning them in a low oven - before applying any surface protection of any kind. Makes a big difference. The first and most damaging oxidisation takes place under the surface, not on it. WD40 is oil based, so it FLOATS ON TOP OF water!! So WD40 can actually seal in moisture.
@@G58 WD 40 means water displacement.
@@lecnac855 Thank you, I know perfectly well what the WD in the name stands for. I also know the ingredients, and understand physics.
Unless you believe that water floats on oil, then I’m not sure why you thought it necessary to state the obvious.
Some bright blub found that if the adjustment screws move from 90 degrees to what you have, you get a finer/better adjustment.
Even SpaceX is moving the grid fins to this configuration on new builds. Better control on first stage reentry.
That was great! I have to go look at my old 3 jaw that I have and clean it up.
This is a great video. Decent chucks are pricey so restoring them is well worth it.

Thank you for sharing. I’ve never used a six jaw chuck.
Happy New Year Keith! Have a great day! God bless!🎚🙏🇲🇾🇲🇾🇲🇾
Wild guess about the adjustment screws not being 90°: when indicating the chuck, it would be beneficial for the adjustment screws to be in line with the jaws so you don’t need to worry about angles
Classic TLC. Well done sir
Nicely done. You should enjoy that one for years to come.
Thanks for sharing 👍
Kurtis on the CuttingEdgeEngineering channel bought a lathe which had an electrical system that was shorted out. He hired a "sparky" who _knew_ his trade, and that sparky was able to replace all the wiring, at a reasonable cost, and handover to Kurtis a working lathe. From Kurtis I learned the word "swarf: [1583] The wet grit abraded from a grindstone; thus the filings or shavings of stone or wood or _iron_ Hence, any fine waste produced by a machining operation, esp. when in the form of chips, or strips or ribbons. Sawdust." (Kurtis runs a machine shop in Brisbane, Australia, and there a "sparky" is an electrician specialized to repair machinery.)
Great job buddy 👍
Great video as always!
That cup you put all the little parts in for Evapo-Rust looks real familiar, think I've wore out 2 or 3 of them....LOL
That was very informative, thanks!
I always enjoy your videos. Thank you and keep up the great work.
As always very informative.
Magnalube is great stuff. Perfect application.
That is criminal what that shop did, putting a machine outdoors to rot. Thankfully there are people like you to find and refurbish them.
The perfect shop assistant knows when to stay out of the Master's way...
I just did my lil 3 jaw cause I had been doing a lot of boring and I started having problems I took it off cleaned with a pic still problems so I took it fully apart and it's amazing how much tiny chips are packed in there I've noticed that the biggest problem is boring cause lots of those chips eventually get pushed back into the gaps back there and get stuck
Nothing like that available in this country, if I ever find one I will polish every part. Precision Bison chuck nice. Thanks
I don’t think you’re doing your recent surgery a lot of good Keith!
I had to order mine especially from the US from travers tools! Tony Johannesburg
Great job 👍
Nice shop kitties!
This was a very satisfying "quick" restoration. Chucks are fascinating works of mechanical engineering and this one is clearly pretty nice. Definitely core content for this channel!
Oh... I think you can use some of the threaded holes to Jack the two parts apart, rather than using the chisel.
Where's the fun in doing thinks the right way?
I bet you are one of those guys that never use a hammer.
🤦
I’d guess if Keith had paid the €2000 new price for that Chuck, there would not have been a hammer any where near it!
Amen to your comments on WD-40. NOT much good a lubricant (very low film strength) but very good as a water displacer. It adheres to metal better than water does, so it creeps under any water and lifts it away from the metal where the water can evaporate without causing any new rusting.
I find putting the items in very hot water after the evporust really helps get rid of the oxides. The water will just evaporate while it’s drying due to the heat of the metal…..
good job keith
Keith had me a little on edge when placing the components in the bucket for derusting. I could hear some clinks heavier than I would have liked with such precision items. Perhaps the burr on the chuck key pinion keep groove was sustained there.
i HAVE TWO CATS THAT LOOK EXACTLY LIKE THE TWO SUPERVISORS UNDER YOUR WORK BENCH. bY THE WAY GREAT VIDEO.
Good shop assistants...!!!
Great video but God bless you for caring for those sweet animals.
Thanks Keith.
Nice Repair!
Chuck maintenance is on the agenda here - at some point in the future !
Looking way better.
Keith, your shop cats BENEATH the table are a sort of harmonic balancer for all the activity on TOP of the table and with that, balance in the universe is maintained.
Always good Videos
Ginger and Mary-Anne knew that you had it all in hand.
Came for the chuck, stayed for the shop kitties 💖
