In this video I will walk you through the process of refurbishing three chucks to fit my LeBlond metal lathe - a 3-Jaw, 4-Jaw and 6-Jaw chuck. Grease, grime, and rust is all removed as these chucks are taken apart, cleaned, and put back together to get them ready for use.

I have a bag of glass marbles i got at a garage sale i use to take up space when soaking things, to reduce product usage. Kinda like a brick in the toilet tank to reduce water. Glass marbles are ideal because they are non reactive to almost any chemical you can throw at them, non conductive and fill up small spaces. They also work in an electrolysis tank. Bonus tip, marbles/ball bearings inside any container you need to shake before use like paint, or lapping compound or whatever, really speeds up the mixing. Hold on to your marbles, Once you lose them, things get weird....

@@LAsparkTVWireTestLimited Here is another: If a 4mm allen key fits into a bolt, so does a 4mm ball bearing. If you super glue it in there, nothing but a soak in acetone is gonna get it out. Cant drill it, cant hammer it out, cant grab it..... If you peen over the head of the bolt, the bearing is in there for good... Very effective anti-theft/anti tamper.

Great video as always Mr. Rucker. I'm a CNC machinist looking to go backwards. You, Mr. Booth, Mr. Fenner, and that goof Mr. Lipton have taught me so much in the manual machining world. The shop that I work in, has more antique yet still operable machinery than I've ever seen. I see machines at work...sitting in dark corners of the shop...collecting dust, that I know I could run because of you guys. I can't thank ya'll enough.

zumbazumba1 I agree and disagree at the same time. I run some impressive machines...I throw code at them...make offsets...and I'm good for days. Personally, manual machining is an intimate thing...CNC is less controlled by me...hence the CNC. I'd prefer to be in more control...intimately...while trying not to sound like a dirty bird.

I do get you what you mean ,machinist brother from another mother.For 5 years i am a machinist on manual universal lathes.If you have the right idea they are indeed universal ,from turning one to milling machine ,hobbing gears to making keyways.You aint gonna do that on a 500k worthy cnc lathe machine.Cnc machines can do amazing things but also they kill the creativity,there is no room for improvisation. I recommend that you stick to your job with cnc machines for $$$ and secretly cheat on it with a manual south bend or similar lathe in your basement. When a man owns a milling machine and a lathe with right tools and right mind and materials nothing is impossible.

zumbazumba1 Honestly, I couldn't have said it better myself. You, my friend, are my machinist brother...from that other mother of which you speak. I currently have two engine lathes on my radar...an exceptional Clausing and an old clapped out Mori Seiki. Bridgeports are a dime a dozen in my situation...but...I'm a lathe guy...have been, and preferably, will always be. It makes me think of Abom and how much enjoyment he gets out of that old Monarch of his. The thing is... I want that. I'd prefer not to have a fanuc controller screen staring me in the face all day. I do enjoy what I do...don't get me wrong...but I'd prefer the calculations were made from what's under my hat...rather than some computer.

When buying lathe biggest concern is condition of the slides,most will have wear from use(usualy around chuck where people work most of time ).Check the wiggle of the compound and the cross slide with dial indicator -those have gibs that can be tighten usualy but sometimes they need new gib(can be made new but costs money ) or they need to be ground and scraped. Check for backlash in a cross slide screw-1/10 of a mm is a normal backlash when nut and screw are new(also can be made new but costs money).If cross and compound slide have no play and gibs are set correctly backlash wont have that much of a influence on a precision. Check the main spindle,put a dial indicator on is or on the chuck and then with a long bar try to move it up and down-this will tell you a condition of ball bearings /bushings.(can buy new -again costs money). Check if bushings /taperd roller bearings can be tightend-old machines use bushings that are good up to max 600rpm and need to be oiled.Newer machines use ball bearings on main spindle axe and their speed s go up to 3000 rpm usualy.-this is important because carbide inserts like higher speeds,older machines were made for hss blanks. Open the cover of the lathe and check the main gears ,if you see any of them are blue(runing withouth oil ) or damaged if they are run away and never look back . Check the tail stock quill with dial indicator -same as main spindle.Lock the tail stock and push quill against chuck to see if tail stock thread is stripped.With your finger check if the tail stock morse taper is smooth and undamaged-this can be reamed if damaged but again its a pain in the ass and costs money. Check the condition of the pulleys on the motor and on the main gear if machine has them,And the condition of belts.-this is easy to make new but again it costs money so why not bring it down. Bring a micrometer and peace of steel to turn and test the machine you are buying.See if it turns too much of a taper.(this can be due tailstock beeing missaligned properly ,run in a slides or machine not leveld properly-i shit you not ) Try heavy cuts(10mm pass for heavy machine ,5-8 mm for meduim ,3-4mm for smaller ones ) and see how macahine handles them.If it doesnt stop the clutch is ok(if it has it,new machines do have ).If it skips the cut clutch can be worn out or simply needs to be tighten(when buying old machine check for spare parts if they are still available-thats one big factor to consider) Last thing is drop the price down for every single mistake you find that can be fixed-it will cost you.Most of the sales guys know jack shit about machines and claim that machine is in PERFECT BRAND NEW condition . I dropped the drill press price form 1000$ to a 400$ when i looked at it and said what needs to be replaced. When i fixed it grand total was 500$ and some time. Old machines can be restored to a brand new condition when scraped and restored for a half of price of a new one - if you know a place where you can send it.I seen it on a youtube guy sends in his surface grinder like 50 years old and they scrape the slides ,repalace ball bearings and for 20k$ he has old- new machine that is capeble of 1/1000 precision grinding that will last for another 50 years to come. This is all that comes to my mind right now ,probably i missed something. Hope you buy something that fits your needs and serves you for many years to come. www.homews.co.uk/page463.html check this dude its Harolld Hall -author of workshop practice series of books.he has many projects you can do and build your own machines for fraction of cost .

Just a quick comment if I may, I was taught that a "Witness Mark" was simply any remnant of the tooling marks on a machined surface left behind intentionally. They were used as an example of how much (or really how little) metal was removed in the final processing of that surface. Match marks on the other hand, were marks put on the visible surfaces to show how two different mating parts were originally assembled. In part just to make certain that they went back together in the correct orientation to each other.

Hey Keith for future reference those threaded holes in the backing plate are called jacking screws. Run into them a lot when working on things with machined fit. One word of caution be careful to turn them in small amounts and equally as you can damage the parts if you get it cocked in its bore.

After watching the video again, when you greased the wear surfaces behind the scroll on the 3 jaw, i noticed the groove in between them ran all the way around, and there was a tapped hole in the groove. I think that little tapped hole on the front of the chuck is to screw in a grease fitting and grease the chuck. If it is, it should have a plug in it when not being greased.

WD stands for water displacement developed in 1940 for drying out distributors in military vehicles. It has varnish in it so after multiple applications the object will get a red tint. I used to work in a gun shop and customer would bring in a red colored semiauto rifle complaining it had stopped working. A soak in the ultrasonic cleaner and some customer education took care of the problem.

Pull apart, de-rust and reassemble. Sounds easy when you say it.. then the work :D nice job. Only thing I would suggest is fitting the chuck to the lathe and getting it all run in true there when you put the body back together. Sure it will be out when you remove the chuck and reinstall it, but at least you are pretty close and should only have to do a little work next time.

Hi keith. Shotly after I got my Monarch lathe I was trying to dial in the run out on my three jaw chuck . My model L is a threaded shaft and the chuck screws on. It has the same kind of set up as yours where the jaws bolt on to the peice that rides on the scroll. It made a huge difference which jaw went on to each of those peices. I did notice that someone before me made an almost unnoticeable number on each one and they were in the wrong place. Once I moved them to coincide with the correct jaw it ran within .0001. Just a thought as you put yours on you might check and see if it makes a difference where they go on your lathe. But great video. Thanks because most every video you and some others do are a great help to me.

Thus you can reverse jaws instead of having a complete alternate set for Inside-Outside The lower jaw MUST be numbered in order to fit the scroll in order. Anyone interested?

I have found that a little bit of orange glow citrus furniture polish and a red 3m scratch bright helps with the stains on a chuck. I've cleaned up a 3 jaw chuck that I just inherited from my brother. See if it will work for you.

I ordered Evap-o-Rust today. I've got a six-jaw I'll have to clean after grinding and a three jaw apart now going through what we see in this video.

If you forget and it evaporates you can just add water. The chemical in the evaporust is not subject to evaporation. What out with some drills and hex keys. The evaporust work by pulling the 02 out of the rush and leaving the iron in the bottom of the pan. It does the same thing with Black oxide. If you reuse product you can dye a part with the black oxide from a previous project

Lovely job Keith. I haven't seen a six jaw chuck before, let alone used one. I must agree with someone else's comment, a brass drift would have been a better choice to get the ring gear out. All primed and ready to go. Cant beat a good drop of lube in the moving bits. Des.

Great job as always Keith, my only concerns are, grease is probably not the best method of lubricating the inner workings of a chuck, because any chips that find's they way in there, will have a tendency to stick to the grease. Oil would be a more appropriate lube for that application. Also, you need to lubricate all moving surfaces, you lubricated the flat surface of the crown wheel and not the center that rotates around that hub, you could be a little more liberal with the oil, just wipe off the excess at the end.

Heck, any "excess" oil will be taken care of the first time you turn on the lathe. ;-)

Grease is FINE. Careless use of compressed air and grinding/polishing on the lathe is a main problem.

ibkoool1 This is sadly very typical of Keith's work, particularly when lubricating parts during assembly. He likes to portray himself as a careful and experienced engineer and yet can't actually see the shortcomings of his own work. Similar examples of mistakes litter his videos.

I watch them because I enjoy the sort of machinery Keith works on. I have spent most of my career repairing antique machines and industrial installations and much of my work was putting right poor or even bad workmanship by previous people who had all the right spanners but little grasp of what they were actually doing. Keith seems to be somewhere on that spectrum in that he more or less knows what to do but cannot portray himself as truly competent to be an instructor and an example to those who wish to learn. In the meantime those chuck components are still wearing out!

The reason the six jaw chuck is more tired is that it is that it can be “bucked” (adjust center). It can also hold onto tubing with less distortion. They are typically less robust than a three jaw.

hi Keith, regards the six jaw chuck, did you get the other set of jaws with it ? there are usually two sets inner and outer. as I expect you know, would be a shame if you only have the one set, keep up the good work, JB UK

Nice videos, thanks. You were talking about the numbering of the jaws matching the slots. Is this because the chuck is balanced like a car wheel? Any slight difference in mass of each jaw might unbalance the chuck if placed incorrectly?
@stargazer7644
@stargazer7644 4 жыл бұрын
No, it's because the scroll is in a different position at each jaw location, so each jaw is cut differently so they meet up at the middle. Otherwise the first one you put in would be the first one to the center. Each successive jaw starts a little deeper as you go around the numbers.

Workshop sinks.. Well worth any extra plumbing to keep others who live in the same house happy. Greasy parts in the laundry/kitchen/bathroom sinks are nearly universally frowned apon. :) One can earn many points for coming into the house with clean hands after working in the shop.

I was taught to tighten all scroll points with the T wrench to balance the strain on the rack inside and not all pressure on one spot.
