I can attest to the awesomeness of this style of chuck- I use a 3 jaw adjustable at work with a collet holding tool in the jaws. I rework aerospace gauges sometimes in the 0.00005" TIR range using this setup manually. People who say scroll chucks can't give accuracy have never used a well made adjustable runout version- like this. Nice to see someone else actually say that out loud.
Excellent job , great the way you detail everything with explanations. Thank you , Master Machinist , my old 6 jaw I'm sure will be torn down and serviced at some point. Since I've never done it before , watching it done just inspires me to do it. I'm always amazed with your work and the way you do things. God bless
Excellent video Stefan! Glad to see you did the tubular handles in the photos. They are so comfortable. I would say something about your video frequency but who am I to talk ;-) ATB, Robin
Yes Robin what ever happened to that giant stone? Collecting dust? Weeds growing around it? Using it as a stepping stone to the get to the top shelves? or what lol. Dont know u so hope u dont mind a friendly msg.
Thanks! The tubular handles are so much nicer to the hand. Did that also to my vice-wrench and the colletcloser on my 5C indexer... Holding my breath until you release a video!
Varying run out using different pinion position on the chuck......that's why one of them has a little "O" mark on it so you don't get lost. Another nice vid Stefan, been following your progress on Instagram, keep up the good work.
Great to see you back. I noticed you use a vacuum when turning cast iron. I do the same and boy o boy, what a difference when cleaning up afterwards. My 6 jaw came with the lathe and needs the cleaning and set up correctly, so well timed video. Thanks.
Stefan, Absolutely outstanding video. I do not own a 6 jaw chuck but now plan to get one soon. Thanks for all the great ideas. Love the music and really love the drive at the end of the video.
Very nice video, great job on that backplate. I have so much respect for you guys using 6-jaws, I almost always use a 4-jaw to help compensate for my poor machining...;-) OTOH when I watch you adjusting each pinion, it doesn't seem too different than a 4-jaw...very nice how you surface ground that backplate, that bore really fit nicely on the spindle nose! :-)
some how I missed this video, glad you got on the 6 jaw chuck band wagon, I can't live with them, i need to cam-lock base to mill. thank you have good day , liked the town video at end.
Seems like an exceptionally nice Chinese chuck. I have a Chinese 5C chuck with the adjustable back and it is also very nice. So they can do nice work at still reasonable prices, just don't look for the cheapest.
Very informative video i have a second hand chuck in my collection and one pinion was marked with a ring of dot punch marks now it makes sense I learned something new thanks
Scroll jaw chucks can be very accurate. I have 2 3 jaws one for rough work and one for precision work. I’m still a 4 jaw and faceplate fan. Nice video !!
I had to chuckle at that as well. Anyone when first learning not quickly teaching themselves to automatically remember to remove the chuck key after once or possibly twice forgetting it, then maybe operating machines isn't for them? Drill chuck keys with the spring loaded "safety" addition are even worse to try and operate. The garbage can is the best place for those springs. :-) Great video as always Stefan, I have the exact same spindle nose on my lathe. I've yet to figure out why they just didn't use a D1-3 mount. It could hardly add much more to the machines selling price and would be a better and more repeatable mounting system. The later models of my lathe did start being offered with that D1-3.
That was a good logical demonstration of chuck accuracy. I was previously of the mind that if one needed to use the same pinion, then the scroll was worn. But in reality, no scroll fits perfectly. And why not aim for accuracy, even though it's not a collet. What was that about Chuck Norris? Haha.
Nice project again, Stefan. To my eye the stick-out of the whole chuck assembly seems a bit long. But since you want to mainly use it for plastic work with its rel. small cutting forces it is plenty rigid for that. Concerning the video frequency of course everybody would enjoy more and more of the good videos coming; daily if possible... But we all know that they are a lot of work. So keep the pace such that it is also fun for you then the excellent quality keeps its level to the joy of everybody: you and the viewers. (and if you keep them waiting a bit they appreciate your videos even more...;-)
Ahoi! Its not much more overhang as with my 3jaw - I used the 6j already for a bunch of stainless and toolsteel parts and, the increased holding power/stiffness from the better clamping outweights the slightly larger overhang by far B) I wish I could do more videos, but making parts and sending them out pays part of the bills, adsense doesnt ;)
Stefan Gotteswinter As I said I am happy with your output in quality and quantity. Have you asked your customers whether you can videorecord making their parts? If they allow it you could make more of your interesting vids. Fenner is doing that often. Hit two birds with one stone.
Keep in mind, filming makes stuff take 3 times as long as it would normal take ;) I try to film as much customer projects as possible, but as said, its just not always possible. And editing can be a chore if the narration is not already done when recording. Voiceover takes forever :/
My older Buck six jaws only had one pinion. Don't know if Buck did that on purpose or not? I have a newer Taiwan made Buck that has two pinions. While there is a slight difference in repeatability between the two it is very slight. Less than .0003 inch. On a older Chinese six jaw I used to run it always ran .0006 with just grinding the jaws. I do a lot of thin wall plastic parts. distortion of the parts when doing ID work is too great with three jaw chucks. I absolutely love six jaw chucks after making the change. Solid jaws like the one you have will go down to smaller diameters without having to make soft jaws like two piece jaw chucks would require you to do also. Your chuck looks to be of very good quality. Nice score!
Yes - Didnt say that it is something new. There are even different styles, Bison has an integral backplate on their adjustable threejaw chucks with tapered, tangential screws.
@Ralph Macchiato That's what we need, sorry. Sovereign states. Germany that looks like Germany, Italy that grew out of Italians, ... I don't want any of those beautiful cultures and ethnic groups to disappear or to become a minority in their own homeland.
Very enjoyable video. You have quite the following on youtube. I see some of the very best machinists and also likeable creators here following your content. = Damn good Stefan.
At 26:38 you use the technical term the scroll thingamabob. I looked at a parts catalogue and couldn't find it. Do you know something I don't...........
Great vid as always. I really enjoyed the footage at the end too. What a charming little town! I could do that on one of my vids but it would show homeless people milling around a sacked out town 😨 lol
Stefan You didn't show a final check, on nutation, or wobble of the workpiece axis relative to the spindle axis. Another way of saying this, I suppose: how perpendicular are the jaws to the face of the spindle nose? including at different diameters?
Still a pleasure to see your video (as your instagram account). A question from a newbie why are you using grey cast iron and not steel? because there no risk for safety and it's cheaper or for any other reason ? thank you for sharing both your project, experience and comments. It's always instructive and interesting. greetings from france !
Gray cast iron is used because of it's vibration dampening abilities and is pretty much standard for most factory machined back plates unless the chuck is designed for and meant to be used on a high rpm machine.
Nice job as always. Is "bee zhon" the proper way to pronounce Bison? I always assumed it was "bye son" because they use a bison in their logo.BTW, you have a "0" on that chuck marking the key hole that was used during manufacture.
Hey Stefan As always nice work, just got a set of twins in form of a 3 and 4 jaw Röhm ZS 140..😁 So i need to make some backplates..Where do you buy the GG25 in that size, Denmark is useless in that area 😏
on your 6 jaw, you use one pinion, lug position for final tightening, but, do you mark all of them and rotate the pinion you do tighten so they all get used and you don't warp something?, in different jobs of course
where did you buy it? could you share some of your ressources where you buy your lathe/mill and other machinists tools please? would be most helpfull. danke :)
It appears the geared side of the scroll plate has galled the rear body of the chuck where it absorbs the thrust of the scroll. Why: Debris? Soft metal? Lack of lube? Insufficient bearing area? Certainly was not high rpm from tightening chuck too rapidly! ;)
You're useless as a machinist if you can't use a 4 jaw. You literally just finished making a video about using a 4 jaw only with extreme pressure angles introduced. I love you videos Winter. Don't be steering young fabricators wrong.
Stefan, Whenever I dismantle things for cleaning and inspection I always wash parts with liberal amounts of cleaning solvent. However I have noticed that you do not do this, but rather use clean rags or shop towels to remove grease. Is there a particular reason for your method that has possibly escaped my logic?

Ahoi! Yes, I dont like to use solvents, especially stuff like break clean (which I dont even stock in the shop) or degreaser (which I also dont stock :D) when I dont absolutely have to.

sixjawchuck..........think i know her , shes the sister of pokerhiney about the spin option for the grinder , cant you use one of those cheapish rotary table stuck directly on the grinders table next to the magnet vice like to find one of these smaller surface grinders one of these days , they aren't eazy to find in that size though . i think you can grind tools cutters and drills with it too if you have the adapter for it
11:30 where did you buy that type of drill? i searched on ebay but hard to find, not sure if my searchwords are correct ( tried "core drill" , and "MASONRY drill") 3:09 next version they should use M16x 0,75 for the fine screws, its a really fine threat ;D (best tap+die i have for now)
@@oldog2 thank you for the idea, looks like its an US brand, shipping from US makes the price nearly double so its not an option. I found the nearest thing which comes close a re holesaws with hardmetal inserts (for metalcutting) they dont go so deep but better than nothing :) edit: found a cheap one www.ebay.com/itm/High-Speed-Steel-Alloy-Hollow-Core-Drill-Metal-Drill-Bit-Milling-Cutter-Z/113813504161?var=414006621311&hash=item1a7fd040a1:m:mwk2CG2Pp19qV-6NdXUZadQ
Hi Stefan, I got DIN55027 studs from this company here in Sweden: smaskin.se/svarvning/fastspanning/tillbehor-chuckar/stod-dubb-med-mutter I got a 200 mm cheapo Chinese 6 jaw for my nice German made Weiler Condor and needed these for making the back plate . Had low expectations on this chuck, but I must say that after similar treatment as You gave Yours, its very accurate. Needed something for large plastic tubing etc. but found it much more useful. Had for a Year now it´s probably my most used chuck. Mine also came with sets of soft jaws. I think turning the back plate in the same lathe its going to be used is a good idea. My Weiler lathe has a stud that makes sure that the chuck goes on the same way on the bolts each time. Noticed Your lathe does not have that feature, but it would be fairly easy to add.

There is always something new to learn from your videos...and yes Welcome back!
Pleased to see you back Stefan, nice work
As usual picked up something new.. rotabroach.. so tired of the chip mess from drilling and boring all the material out to get a 1" hole! Thank You!
Excellent video Stefan! Glad to see you did the tubular handles in the photos. They are so comfortable. I would say something about your video frequency but who am I to talk ;-)
ATB, Robin
ROBRENZ both of you should be posting more often :) but, you know, somehow without sacrificing quality or content...
Yes Robin what ever happened to that giant stone? Collecting dust? Weeds growing around it? Using it as a stepping stone to the get to the top shelves? or what lol. Dont know u so hope u dont mind a friendly msg.
I'm also looking for the next surface plate video.
Thanks! The tubular handles are so much nicer to the hand. Did that also to my vice-wrench and the colletcloser on my 5C indexer...
Holding my breath until you release a video!
Is ATB a secret code of top ranked machinists?
We've been waiting, and were not disappointed!!!
That runout adjustment mechanism is extremely meaty!
Varying run out using different pinion position on the chuck......that's why one of them has a little "O" mark on it so you don't get lost. Another nice vid Stefan, been following your progress on Instagram, keep up the good work.
Ian McDonald and if there is no "O" it is the key hole by the the label.
Thank you Stefan, you teach all the world, thank again from SAUDI Arabia
Great to see you back.
I noticed you use a vacuum when turning cast iron. I do the same and boy o boy, what a difference when cleaning up afterwards.
My 6 jaw came with the lathe and needs the cleaning and set up correctly, so well timed video. Thanks.
Yes - I did a fair bit of cast iron in the recent time, and I learned to use the vacuum, otherwise the shop ends up to look like a coal mine.
I've been battling a 6 jaw Bison for quite a while now. Thank you for giving me a couple things to look at. I really do appreciate it.
Stefan, Absolutely outstanding video. I do not own a 6 jaw chuck but now plan to get one soon. Thanks for all the great ideas. Love the music and really love the drive at the end of the video.

Love it, glad to hear your still alive and kicking
Seems like an exceptionally nice Chinese chuck. I have a Chinese 5C chuck with the adjustable back and it is also very nice. So they can do nice work at still reasonable prices, just don't look for the cheapest.
Top! Könnte dir den ganzen Tag zuschauen. Wirklich toll was du da machst!
Now you can machine high precision macaroni. Take that ThisOldTony ! :D
Thanks for explaining balanced cuts. I wish I had known that. So obvious once you know, but I didn’t!
Very informative video i have a second hand chuck in my collection and one pinion was marked with a ring of dot punch marks now it makes sense I learned something new thanks
Scroll jaw chucks can be very accurate. I have 2 3 jaws one for rough work and one for precision work. I’m still a 4 jaw and faceplate fan. Nice video !!
"I always loose the spring on the key..."
xD
I have realy no idea how this happens :(
Take note, He drops the key less than a minute later. All I could think was, I think I found out how he losses the spring hehe...
"lose"
"lost"
I had to chuckle at that as well. Anyone when first learning not quickly teaching themselves to automatically remember to remove the chuck key after once or possibly twice forgetting it, then maybe operating machines isn't for them? Drill chuck keys with the spring loaded "safety" addition are even worse to try and operate. The garbage can is the best place for those springs. :-)

It's a sweet Stefan Sunday !
Excellent as always, Stefan. Who ever could do a thumbs down? Strange isn't it.
Don't turn on it, take it apart!
Bobby dazzler! :D
Bloody ripper.
Bob's your uncle.
Bee's knees!
Crikey, you speak Australian too.
Nice work! I especially loved the callout to EEVBlog ;-)
call-out was nice, but the accent 'orrible ;)
Good to see you after a long time Stefan. Congratulations on the very nice new acquisition :) Don't be a stranger now, drop by once in a while lol
That’s a great idea to remove the chuck for testing the fit. Nice video man. Good to see you as always
HI Stefan- thanks so much for another excellent video
good timing on video as I am looking at purchasing a six jaw for my lathe (200mm),excellent job!
Ausgeseichnet video, Stefan. Vielen dank!
Thanks Stefan, you will be spoiled with the six jaw, you can chuck up eggs with it, and they don't have to be boiled!
Good to see you. Good job and thanks for the video.
Just so enjoyable to watch.
Great job , ENJOYED !
Another great video Stephane, keep em coming! Cheers, Doug

great video production and explanation of procedures.
enjoyed--great discussion/instruction/build
The adjustability shown is an old idea. First patented by Buck, et al. in 1953. U.S. Patent no. 2639157. It expired in 1968.
Yes - Didnt say that it is something new. There are even different styles, Bison has an integral backplate on their adjustable threejaw chucks with tapered, tangential screws.
Nice to have you back.
prefer this music 😉
Yet another great video! Thanks for posting.
Whoa, whoa, whoa, where is our regular intro music?
I used the wrong template ;)
I was wondering where the murder mystery intro music went.
Very beautiful town or village you live in.
Let's hope Angela Merkel doesn't ruin it.
@Ralph Macchiato That's what we need, sorry. Sovereign states. Germany that looks like Germany, Italy that grew out of Italians, ... I don't want any of those beautiful cultures and ethnic groups to disappear or to become a minority in their own homeland.
Nice job Stefan
Thanks/Danke!
Happy Birthday, this video!
Cool!
Steven, I have the same problem with my chuck keys... that spring always seems to fall off.
Very enjoyable video. You have quite the following on youtube. I see some of the very best
machinists and also likeable creators here following your content. = Damn good Stefan.
Danke für das ausführlich Video. Mach weiter so.
Dankeschön!

:D No hupa dupa pls ! Nice to see your stuff again.
Great work as usual
i like your video ! from vietnam
Stefan
You didn't show a final check, on nutation, or wobble of the workpiece axis relative to the spindle axis. Another way of saying this, I suppose: how perpendicular are the jaws to the face of the spindle nose? including at different diameters?

greetings from france !
Gray cast iron is used because of it's vibration dampening abilities and is pretty much standard for most factory machined back plates unless the chuck is designed for and meant to be used on a high rpm machine.
Mostly because cast iron wears better than unhardened steel. Dampening abilities of cast iron on such a solid part do not have much effect.
I tried to say six jaw chuck 100 times but only got to 4 1/2 ☹️
Stefan - backplate from cast iron or from steel? What is advantage of cast iron backplate if there is any?
Those are some tasty fuel prices at 28:53
None of the gear parts are sintered metal? Thanks for sharing with the world!
I think they are die-forged.
great video Stefan, I could imagine a chuck called chuck Norris but not a bridge cause no one crosses chuck Norris
Random chuck norris fact - Check.
Chuck Norris only has one jaw but he can grip any shape. The only catch is that he spins the lathe around him.
Good job
Nice job as always.
Is "bee zhon" the proper way to pronounce Bison? I always assumed it was "bye son" because they use a bison in their logo.BTW, you have a "0" on that chuck marking the key hole that was used during manufacture.
6 flats on the back plate would be even more useful
That's Laaber!
Can you recommend this Zentra six jaw chuck or would you have bought another chuck if it was today? How often do you center it?
Hey Stefan
As always nice work, just got a set of twins in form of a 3 and 4 jaw Röhm ZS 140..😁 So i need to make some backplates..Where do you buy the GG25 in that size, Denmark is useless in that area 😏
on your 6 jaw, you use one pinion, lug position for final tightening, but, do you mark all of them and rotate the pinion you do tighten so they all get used and you don't warp something?, in different jobs of course
yes build a spin grinding table!!!!!
where did you buy it? could you share some of your ressources where you buy your lathe/mill and other machinists tools please? would be most helpfull. danke :)
Interesting as ever Stefan. Is the three jaw going to clutter up the shelf from now on or is there a situation where you will still use it?
Yep - As a Softjaw chuck :)
As we speak, I got it mounted with large aluminium pie-jaws bored for a recuring job.
Great use for it. Looks like a 6 jaw may have to be on the birthday list for me!
It appears the geared side of the scroll plate has galled the rear body of the chuck where it absorbs the thrust of the scroll. Why: Debris? Soft metal? Lack of lube? Insufficient bearing area? Certainly was not high rpm from tightening chuck too rapidly! ;)
Good job 👍
Do you ever plan on marking or filling the pinions to have a dedicated one to use, or do you just use the pinion with the 0 punched outside of it?
I go with the 0-punched one.
You can't get them anywhere on the world. Like they will ship it anywhere, but Poland it takes almost 40 days of work, to earn this much :v
You're useless as a machinist if you can't use a 4 jaw. You literally just finished making a video about using a 4 jaw only with extreme pressure angles introduced. I love you videos Winter. Don't be steering young fabricators wrong.
Stefan,
Whenever I dismantle things for cleaning and inspection I always wash parts with liberal amounts of cleaning solvent. However I have noticed that you do not do this, but rather use clean rags or shop towels to remove grease. Is there a particular reason for your method that has possibly escaped my logic?
Regards

Ahoi! Yes, I dont like to use solvents, especially stuff like break clean (which I dont even stock in the shop) or degreaser (which I also dont stock :D) when I dont absolutely have to. I use a fair amount of IPA, which is not as bad for the health and flashes of clean. Parts like the chuck go in the ultrasonic cleaner with a basic degreaser solution.
I also use ipa, but the Indian pale ale variety, it's also good for health.
IPA = the beer ?
Isopropanol Alcohol
Hello Stefan, the Project Link does not work
sixjawchuck..........think i know her , shes the sister of pokerhiney
about the spin option for the grinder , cant you use one of those cheapish rotary table stuck directly on the grinders table next to the magnet vice
like to find one of these smaller surface grinders one of these days , they aren't eazy to find in that size though . i think you can grind tools cutters and drills with it too if you have the adapter for it
You can get circular mag chucks designed specifically to fit on a rotary table for grinding round things :)
Good video. Can you show us more of your inside micrometers ? The mitutoyo and starrett ones are very expensive. What brand are your ones ?
Those are Mauser - Old german company, got them off ebay for little money.
Is Hoopa Doopa a technical term? heh
Super technical. Makes you seem to be total legit!
Right up there with thingamabob and whosawhatsit... I use them all the time and feel completely legit.
Damn.. a bison 6-jaw chuck costs around 2500 €. I get why you're going for clones
11:30 where did you buy that type of drill? i searched on ebay but hard to find, not sure if my searchwords are correct ( tried "core drill" , and "MASONRY drill")
3:09 next version they should use M16x 0,75 for the fine screws, its a really fine threat ;D
(best tap+die i have for now)
try putting rotabroach in your search
@@oldog2 thank you for the idea, looks like its an US brand, shipping from US makes the price nearly double so its not an option.
I found the nearest thing which comes close a re holesaws with hardmetal inserts (for metalcutting) they dont go so deep but better than nothing :)
edit: found a cheap one

Hi Stefan, I got DIN55027 studs from this company here in Sweden:
smaskin.se/svarvning/fastspanning/tillbehor-chuckar/stod-dubb-med-mutter
I got a 200 mm cheapo Chinese 6 jaw for my nice German made Weiler Condor and needed these for making the back plate .
Had low expectations on this chuck, but I must say that after similar treatment as You gave Yours, its very accurate.
Needed something for large plastic tubing etc. but found it much more useful. Had for a Year now it´s probably my most used chuck.

My Weiler lathe has a stud that makes sure that the chuck goes on the same way on the bolts each time. Noticed Your lathe does not have that feature, but it would be fairly easy to add.
Thanks for the interesting video!
why
because?
HOOBAHDOOBAH!!!
was the smoo out china not great for clean parts
Welcome back :-)
Stefan-
Always glad to see another video from you; clear, concise and accurate, just like your workmanship!
Many thanks...
Bill
Glorious to see you back. Classic Stefan excellence in presentation and execution.
_Dan_
Nice clean up and get in operation video. Audio got tough there at the end, I could only make out some of what you were saying.
Thanks! Not sure what with the audio happened. But I guess what I said was not as important ;)
