Micro chuck & Sensitive Drilling for Mill & Lathe

In this video, we modify a JT1 Morse Taper arbour to fit a micro chuck for use on the mill. . We also make an adaptor for the tailstock die holder to be used to hold the micro chuck as a sensitive drilling device on the lathe.

keep saying to myself i must make one. now i think you have spurred me on to do it!

Hi Paul, thanks for the comment. Lol, glad I have managed to provide some inspiration! Cheers, Jon

Good work. We shared this video on our homemade tools forum this week 😎

Nice job. Good review of a handy little setup. In a bit of irony KZbin was pushing an ad before your video to maximize men’s well….shop equipment 🤭. All the best Dan

[@jonsworkshop]

Hi Dan, thanks for the comment. Lol, men with small tools eh? My god that KZbin algorithm is bloody smart! Cheers, Jon

Hello Jon, Nice work, I have this on my list of things to do... I have a slightly different approach planned... enjoy you Sunday... Take care. Paul,,

[@jonsworkshop]

Hi Paul, thanks for the comment and feedback. Please share your thoughts when you do attack this as mine isn't 'perfect'. The more idea's in the mix the better. Cheers, Jon

Nice addition to the collection Jon, great for super fine work. Thanks for Sharing Take Care Kev

[@jonsworkshop]

Hi Kev, thanks for the comment. Yep, certainly going to make life easier in the future on small drilling jobs. Cheers, Jon

Hi Jon the micro chuck is going to be very useful for you engine builds I too need to make one of these thanks for sharing Cheers.

[@jonsworkshop]

Hi Paul, thanks for the comment and feedback, much appreciated. Cheers, Jon

[@mikeparfitt8897]

Another possible source of "tailstock" error could be from the chuck itself. Put a gage pin into the small chuck and the other end in your main chuck and a dti on the parallel shank and see what the runout is. West German chucks are usually top quality, but this one could be a post bierfest example.

[@jonsworkshop]

Hi Mike, thanks for the comment, yeah, no country is exempt from a Friday afternoon moment lol. I will run some checks in the mill on it and show them in a future Blether video. Cheers, Jon

[@TERRYB0688]

Nice job Jon, nice wee Chuck, didn’t realise that keyless chucks where that old,

Hi Terry, thanks for the comment. Good point, neither did I, and I hadn't given it a thought until you pointed it out. Cheers, Jon

Hi Peter, thanks for the comment. I definitely will, it's a great addition for tiny work. Cheers, Jon

Gday Jon, this sis a great setup, I really like the die holder and I think I’ll have to make one the same or similar, great job mate, Cheers

Hi Matty, thanks for the comment. It's certainly going to make model engine manufacture easier. Got you email buddy, will respond soon. Cheers, Jon

Great little chuck Jon. Will definately be handy to have in the shop. Steve.

[@dermotkelly2971]

Great work John. It's amazing what you can do to make life a lot easier in the shop. Some of those small micro chucks are very expensive.

[@jonsworkshop]

Hi Dermot, thanks for the comment, yep, every next toolmaking project enhances the overall capability, I am gradually getting more equipped and enjoying the journey. Cheers, Jon

[@KevinWoodsWorkshop]

The drill below centre won’t be a problem it’s just the clearance being taken up on the sliding parts, once it’s found the centre it will stay there. You see this often. Nice Chuck you have and it’ll be put to good use.

[@jonsworkshop]

Hi Kevin, thanks for the comment, yes, for shallow holes I think it will be OK as you say, but I think any deep holes may end up breaking drills (not sure). I may make another cartridge to hold the chuck back end, but make it in the 4 Jaw and deliberately throw the centre hole eccentric by about 0.04". This way I can rotate to find true centre, mark it up then mill the clamp slot (this should work). Cheers, Jon

[@graemebrumfitt6668]

Some guys have big things Jon others have small things... I personally have very small things, drill bits that is for my little Proxxon mill :) Nice end result Dude, stay safe n well! TFS, GB :)

Hi Dean, thanks for the comment. Lol, maybe, who knows what I will get up to. Cheers, Jon

[@daveticehurst4191]

Jon, I'm glad YOU spotted the below center problem, saves me telling you. LOL I think that you bent the 1 mm drill in the lathe as it had to cut upwards. Regards from Australia.

[@jonsworkshop]

Hi Dave, thanks for the comment. It's true what they say, the camera never lies! I honestly didn't spot this during machining but the video is very clear. Already have a solution in my head (another cartridge but done in the 4 Jaw with the bore about 0.04" eccentric) should only take 30 mins to make and will allow me to adjust to be bang on centre. Cheers, Jon

[@Bakafish]

You may have wanted to leave a small shoulder on that arbor so that you can more easily remove the chuck from it with wedges down the road. I'd also mention that (although hard to find and not cheap) "Globe" Japan makes a J1-10mm precision straight shaft arbor. I just got one for a similar Albrecht chuck for my mini-mill.

[@jonsworkshop]

Hi Jason, thanks for the comment. Good point. I think there is just about enough gap still for some thin wedges. Will check Globe out, thanks. Cheers, Jon

[@garywilliams9602]

Another great video Jon, made mine sometime ago for the very same reason, could not get small drills in my large chuck. I used a small Jacobs 0 - 1/4 for mine. Good idea to use it for a sensitive drilling attachment. You have given me another project for my workshop!!🤣 Keep up the good work Jon👍

[@jonsworkshop]

Hi Gary, thanks for the comment. It's certainly going to be much easier getting the drills to run right in the mill now. Cheers, Jon

I picked up a nice chuck like this and it had a taper loosely knocked onto it. Not sorted that yet as was still faffing with the 4-jaw chuck mount.

[@Blou55]

Great Jon Very useful. That's several time i see you drilling or tapping and i always ask myself what is that "milky" stuff you used ??? Thanks.

[@jonsworkshop]

Hi Blou, thanks for the comment and question. It is soluble cutting oil (mix with water to make coolant), there are many types available and the oil content stops rust developing. Cheers, Jon

[@jonedmonds1681]

Have you tried adjusting drill runout by knocking the collet nut when slightly backed off.

[@jonsworkshop]

Hi Jon, thanks for the comment. At this point I am not sure if it is the chuck or the drill. I will run some checks and update in a future Blether video. Cheers, Jon

[@Rustinox]

I recently bought a similar high precision drill chuck, the same brand as yours, for over 80€. It has 0,1mm run out :-( So, maybe check yours for run out too. Just to be sure. Btw, did you receive my email from 12 feb. 2022 ?

[@jonsworkshop]

Hi Rusti, thanks for the comment. I am planning to run some checks on the chuck, I will show them in a future Blether video, thanks for the info on yours. I have just checked, for whatever reason, your email had gone into my Spam box. Will reply soon. Cheers, Jon

[@eyuptony]

Enjoyed watching Jon, it works really well. Is the micro chuck a recent find or have you had it stashed away lol. Tony

Hi Tony, thanks for the comment. Recent acquisition for me, it was very kindly donated to the channel by one of the viewers following seeing me struggling with the big chuck. Cheers, Jon

Jon would it be possible to use mist coolent instead of your little bottle? Christopher from Down Under

He could but at present he has no compressor or room for it.

Hi Christopher, thanks for the comment and suggestion. As Dave has said, compressor and space are the immediate blockers, however, I may look to address this in the future. Cheers, Jon
