Restoring a Rusty Bison Six Jaw Lathe Chuck

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.

[@g000phy]

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.

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.

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

[@FinnoUgricMachining]

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.

[@w056007568]

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.

[@lecnac855]

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.

[@andrewmantle7627]

Hear hear.

[@G58]

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.

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.

[@philipmackin1025]

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.

[@gsh319]

Great stuff as always big guy!.

[@jensschroder8214]

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.

[@52Ford]

They measure the clamping pressure annually??? sounds painful... and sort of cruel. Joke.

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)

[@petermurphy3354]

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

Nice Video. Thanks. Bison has a rebuild procedure video for these chucks on KZbin - 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.

What's even better is WD- 40 has a whole bunch of different formulas that are good at different things. Like they have one that is a little thicker that sticks to what you spray it on or electrical contact cleaner.

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.

At work, I use a South Bend lathe, I try to keep it clean....we use it to make a special brush that is used for cleaning out casting items for the railroad industry. I have been using this machine for the better part of 16 years and to my knowledge, it has never.....ever.....been taken apart to clean it.....it's a 3-jaw, that takes carbon steel flat wire and turns it into coils for the aforementioned brushes. Am unsure as to what areas in the casting process these are used, and I have asked several times to see a video of the brushes being used, but it appears to be secret....either on our company side, or the customer side....as if I would attempt to get into casting railroad parts. :-/ MAYBE someday I will sneak a photo of one of these brushes to you...(like in Facebook)....they do go into a tube, of sorts, to do the cleaning aspect, I would still like to see them in action.....Until another day.....Peace.

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.
