Making Copper Soft Jaws for the Four Jaw Chuck

This little thing was on my list for quite a long time. Everytime I use my four jaw chuck I have to deal with sharp bite marks from the chuck. Especially on soft materials like aluminium this is a real problem. It is quite common to have some sheet metal jaw protectors which get between the chuck jaws and the workpiece to prevent the workpiece from bite marks. So now it is time to make my own ones from a piece of copper sheet metal 17mm wide and 0,5mm thick.

I hope, you enjoy this little project.

Just made these this evening. Very happy with the outcome, thanks for the idea. Namaste and love from India

Very nice way to do it. I have a 100mm version of the exact same chuck and I know what Im going to make tomorrow. Thank you

There's a hell of a lot more to that than I would have ever suspected. They turned out perfect though, well done.

[MirekDvorak]

Simple, functional, simply great. As always...

[TalRohan]

Thankyou for sharing, these look really neat and tidy as well as being practical

[Lone-Wolf]

That a nice project that I need to do too to my mini lathe chuck. Well done. 👍👍👍👍

Great video showing an easy process.
Thanks for sharing.

Another solid video with a simple and quality upgrade 👍🏻 keep the videos coming 🤗

[boltonky]

Really cool and such a great idea i need to do this myself cause my chuck jaws ain't flat no more and requires a surface grinder to do it right

If you use quick-couplers on the hydraulics, you could put the trailer behind the other Kubota. If I remember correctly you used an "ATV-pack" earlier? I suspect that you could fit the saws and the "ATV-pack" on the side-by-side... You are a strong couple so you could manage to use the controls standing 🤭🤣.
Or just put some chains on the tractor when winter is coming. One pair of chains every ten years or more is collateral damage 😜...

Nice addition. I was wondering why you were drilling those holes at the start and it became obvious later on. 👍

Nicht schlecht, aber wenn man die 2x2 Enden miteinander hart verlötet kann man das noch schönee zum innen spannen verwenden.

Quinn lässt grüßen😉 Wenn du den Cut der Laschen exzentrisch machst (eine Lasche kurz, eine Lang oder nur eine Lange) kannst du die Backen auch umgedreht verwenden für große Werkstücke. Natürlich nur wenn man die Backen in deinem Futter umdrehen kann...

Hi. Gute Idee gegen die ständige Kratzer von der Spannbacken. Mit Kupfer kann man viele schöne Sachen machen. Wenn der nur nicht so teuer wäre. 😂
Sag Mal, wie zufrieden bist du noch mit deinem neuen Motor? Wie langsam kannst du dem Motor einstellen (Drehzahl)?
Und natürlich ob der Motor noch genug Kraft hat um zum Beispiel Gewinde zu schneiden?
Ich meine ob der Motor auf der niedrigsten Drehzahl noch Power hat?
Meinst du das du mir die paar Fragen beantworten kannst? Ich wäre dir sehr dankbar.
Danke für deine Video. Wünsche dir alles gute und ein schönes drittes Advent. Bleib gesund.

Гораздо проще на деталь намотать один оборот алюминиевой фольги от пивной банки.

Great video!
I have some questions though.
What are the name of the scissors you used to cut the plate?
And can you use these on a 3 jaw chuck? Or would they make your part run off center? Sorry if these are stupid questions but im completely new to hobby machining

Just a few weeks ago I made these for my 125mm chuck. No so pretty but still do the job :)

[elluisito]

U must be 4ich, that copper these days must be worth a furtune hehehehe all jokes aside, nice project and thanks for sharing 👍 😊

Sorder the joints, I don't know if that's how you spell Sorder.

Oh Joe, thats the worst video you have ever made.
I even had to check after the paper template that it really was you.
I am of course referring to your steel rule.
We both know that it states on it only to be used at 20 degrees C.
I think you should have a round (about dial indicator size) thermometer affixed to the rule.
The thermometer scale should be replaced by an +/- Error scale with zero error @ 20 C.

Thanks.
Best wishes.
