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.

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.

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...;-)

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 ;)

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.

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!
