A Chuck To Clamp Them All | Making A Split Jaw Chuck For The Mini Lathe

Рет қаралды 63,369

Special tasks require special tools. I have a lot of workholding options for my lathe but nothing for clamping special parts like thin washers or disks. So I came up with the idea of making myself an 80mm split jaw chuck for my Mini Lathe. This type of lathe chucks is often found on bigger industrial or CNC machines. As far as I know there is no 80mm version of a split jaw chuck available on the market, so I had to make my own.
So I'm modifying in this video an off the shelf 3 jaw chuck into a split jaw version. That means that there are base jaws on which you can screw on all different kinds of top jaws. In my case I made aluminium top jaws which can be adapted to clamp very thin parts.
So in general this type of chuck is extremely versatile and can sometimes be the only option to clamp special or odd shaped parts.

But they were all of them decieved. In the land of Germany, in the Fires of Mount Doom, The Dark Channel 'We Can Do That Better' forged, in secret, a Master Chuck to Clamp all others. And into this chuck they poured their cruelty, their malice and their will to dominate all chucks. One Chuck to Clamp them all.

@Lwimmermastermetalart Ай бұрын

That was neat for your tiny lathe. Having a full size lathe they make what they call emergency 5-C collets. One for internal holding and one for external. Different size ones. With the larger ones you’ll need a tapered closer to help close the OD. They work awesome. I have several. They are soft so you can bore and reborn. And the others can be returned. They have a screw in the center which pulls to expand the fingers.

@WeCanDoThatBetter Ай бұрын

Thanks for your comment! Yes, I know them. I guess on my small lathe there is no way of using proper emergency collets. So the chuck has to do the job :)

I went through the same process for my EMCO Compact 5 CNC Chuck, except, Soft jaws are not available for these Chucks, so i made them myself.. having a CNC Mill greatly helps. So i measured the original jaws, drew them in CAD, and milled new jaws from 1.2510 steel. i milled a raised "Cross" on top, so i only have to mill a cross in the topjaws, which is way easier.. I too Faced the new Jaws in the lathe, before milling the locating features, then drilled and tapped the holes. the top jaws were also turned to the same height, after milling the cross and drilling the holes, and i now can clamp very delicate parts, like watchcase backs on only .8 mm, works a treat!.. What's also Cool, For working with Hexbar, you can Mill a hex in the jaws, to firmly grab it

@cocon16_PW Ай бұрын

for such small rings like washers to hold it the jaw the notch cut in the jaw should be slightly conical "to the inside" so it gets pushed against the face as you clamp. Your inset cutter would work great to make such notch. Either way cool build!

This is the first YT project that I genuinely want to replicate for myself but I can't find the chuck on the site. The only lathe chuck and jaws listed are from Röhm. At any rate this is great idea. I always wanted soft jaws for my mini lathe and somehow never thought of buying a set and simply modify them to fit my own blocks.

Workholding washers for id or face work can be done with a normal collet chuck- if you slip a longer piece of material the same od as the washer (with a perpendicular turned face) into the collet first Then push the washer into the collet Can get really good face runout repeatability but it can be a little fiddly to set up

@fna-wrightengineering Ай бұрын

Great work! This is something I've been thinking about doing for a long time, and it's awesome to see that it can, indeed, be done. Something to make milling the slots/registers a bit easier: Mill from only one side (I usually mill from the fixed-jaw side of the vise), and rotate the workpiece 180* every cut. This will ensure that the feature is perfectly centered, and removes any possible error from repositioning the cutting tool to the other side of the work. You just have to remember to divide your remaining material in half, when adjusting for the next cut.

I later did, you see that in the video. I was a little bit concerned if I can take so much material off on the lathe. It might have worked I guess.

@chrislawrence309 11 күн бұрын

Any reason why, after cutting the jaws to length you didn't return them to the chuck and face them to length, rather than 3 individual set ups in the mill?

@jamestennant1640 Ай бұрын

So... why not put the jaws in the chuck and turn them down on the lathe instead of sawing and milling?? Did I miss something?

@WeCanDoThatBetter Ай бұрын

Hi, good question. I could have done it that way but thought it would be easier to junk away some material first before the final finish on the lathe. But considering the time and the wasted jaw I probably should have done it as you said in the first place... :) Always learning ;)

It wouldn't be as much fun :) but Maprox makes some nice 6 jaw chucks for thin parts, not exactly cheap but they can be found used.

I think there are no 6 jaw chucks with 80mm. I'm even not sure if there are ones with 100mm. 100mm would be ok, but 125mm is definitely too big for this lathe.

Great job! I do have to point out that you are promoting unsafe practices. Even though your machines are small, unaware people do imitate what they see. Long sleeves and running spindles is quite unsafe. Also reaching in to grab a part while the spindle is running, big no no!! Please be aware of what you put out there. You do have the responsibility to exemplify good shop safety practices, both as the good machinist that you are, and also as a content creator. Keep up the good work!
