I’ve had mine for 50 years it’s perfect still now that is money well spent
Right On! 🙌 That’s a great testament to the Albrecht Chuck! Great quality!
Excellent video…the best I’ve seen on the Albrecht….
The reason Albrecht don’t use lubricants is because they end up looking like yours if you do…
Ive never used grease on any lathe or drill chucks as it just acts like a magnet for dirt and chips, and ends up going hard like varnish and can seize the chuck…if you do want to use a lubricant, a fine oil like 3 in one is plenty good enough and makes future maintenance so much easier…
I use just a film of CMD Extreme Pressure Lube #3 for applications like these.
Nice video. Now I know how to dismantle my chucks. One remark: Why do many You-tubers call these steel spheres which love to fall on the floor and roll into an inaccessible corner, "ball-bearings"? A ball bearing is the assembly, consisting of inner- and outer race etc., and off course the balls... So, in my opinion, these marbles should simply be called 'balls'. Another tip: Using an infrared temperature gauge on metal is likely to produce a false reading. The metal reflects light and heat (infrared), so the thermometer actually reads (part of) the temperature of the environment. Stick a piece of black insulating tape on the metal surface and read the temperature of the tape. More accurate because the tape does not reflect the radiation from the environment. (Google emission coefficient for more info). Regards, M.
hmmm, more simple then I thought. My Albrecht chuck needs service like this. Now I feel I can and will get it done. Thanks
Right On! 🙌 Yeah not too bad! Obviously I need to do more regular maintenance on mine and it’s easy to pop it open with the right setup. Thanks for watching!
The reason why tapers are longer than they should be, at least most often, is the fact that someone at some point ground the taper in as to repair some dings or dents that were imparted to the surface, most likely when the arbor was dropped during assembly or maintenance...
I like your use of stones... Those hard stones are to me known as wood chisel honing stones, tho, that is only because that was the first instance where i came across the ground hard stones for tooling... They really do some amazing work in careful hands... And you didn`t abuse them on that properly raised burr, but went for the coarse stone instead to begin on it... Nice!
Speaking of lubrication, i tend to use spindle bearing grease for chucks, non channeling spindle grease that is... Tho, every grease channels a bit in some scenarios... If you use any lube on the chucks, you have to open them up at least around every 5 years and service the lubricant all over... Shit can get contaminated, absorb moisture, collect micro chips and so on... That`s why no lubricant is specifically stated by the book... I would not run any chuck dry, but yeah, if you want it to last, you have to take period care of it... The 5 years i stated is only due to that being the recommended service interval for my specific spindle grease... NSK states that bearing grease can far surpass it`s recommended lifetime and can be safe to remain in use, yet they also state that it should be checked and even sent to analysis if you are using it after that long a period in a high grade, precision system... A chuck is no high precision spindle bearing, but it is an instrument of sorts and should be treated well... Just change that grease every so often... Better to prevent than to contend with issues caused by neglect...
All in all, a nice job!
Best regards!

When I saw you stoning the different areas like a Surgeon I knew the action was gonna be Buttery Smooth when you got done.
Man that chuck runs so smoothly now! 🙌✨ Right On! 🙌 🥓🥓🥓🥓
Excellent video. I have two chucks that need service. This motivated me to proceed.
Oh Right On! 🙌 Nice! It sure felt good to get this one cleaned up and in good working order! Thanks for watching!
@@RightOnJonCrane what Are Those Wedges Call?
@@rogertyler3237 Hello Roger, what wedges are you asking about? 🙌
I'm restoring a drill press inherited from my late father and finding suitable YT videos to manage the different components has been a life saver.
I didn't even know the shell had a threaded hood!
Looking at some differences - mine has an insert not machined jaw guides and my jaws have at the top 1/3 serrations. It's likely a cheap copy :P.
Thanks Jon.
Right On Michael! 🙌 Sounds like you have a great project on your hands. I’m curious now what kind of drill press you have. I’m glad you’re keeping it alive. The tools I have from my father and grandfather are some of my favorite possessions.
Best wishes on your restoration!
- Jon ☀️🌲
What an excellent tutorial. Really amazing camera angles and close ups. Deluxe work. Cheers
Right On! 🙌Thanks Joe! I was doing my best to get the detailed shots for a detailed job. Thanks for the compliment!
Not sure how true it is but I was told by foreman years ago the wedges are called 'Fox Wedge' and it applies to any matched pair of wedges that move outer surface parallel.
When I was doing geology in school in 1970's, we always said 'tights come down, mites go up', made it very easy to remember 😁
Right On! 🙌 Fox wedges sounds good! Yeah for some reason the stalagmites thing sticks out in my mind too. They are fascinating to look at!
Very interesting and excellent tutorial. I recently did a Jacobs Chuck that was sticking and now as good as new. Thanks for the video.
Right On! 🙌 That’s cool Tony! I have some Jacob’s chucks I’m going to do next. I’m sure that’s nice to have it running smoothly!
@@RightOnJonCrane looking forward to it
very nice and clean Jon..well explained..
Right On! 🙌 Thanks! I appreciate the nice compliment!
Another note... Jon is not kidding on how very little grease should be used. If you use too much grease or any amount of oil, the chuck will not tighten and hold a drill bit. It will feel like a spring when you tighten it, and not hold a drill shank. So just use barely any grease. Just a super thin amount. --Doozer
Right On! 🙌 That’s very true! It’s amazing how sticky that lubricant becomes! Thanks for the good comments Doozer!
Lately, I bought two Albrecht-chucks from China for USD 14.99 (free shipping). One for my milling machine and the other for the drill-press. These chucks work smooth and fine - and runout ist less than 0.01mm.
And we are shocked when our tool manufacturers go bankrupt and there are no alternatives left in the free world.
@@anandarochisha This is simply the free cannibalistic and predatory market: When one supplier sells his products for a ridiculous price and one western manufacturer buys these products and can sell his manufactured goods for a ridiculously low price too, other manufacturers have to flip their suppliers too - otherwise they went into bankruptcy. Deng Xiao-Ping, the architect of the WTO-1995 globalism decrees knew this. It is all but a coincidence, he told the world, real power would no longer come from gun barrels, but from Chines factory buildings.There is nothing, we can do against, since it would take generations (!) to reindustrialize the West.
Exactly what I've have been looking for. Thank you for the video.
Right On! 🙌 Glad you liked the video! It’s very satisfying to do maintenance on items like this!
excellent...and thank you
I can attest to the superb quality of these chucks. Oftentimes you even get one with an integral pull stud when you buy a machining center.
Right On! 🙌 Yeah such great quality! Thats interesting with the pull stud! Thanks
Cool video - I've got several Albrecht keyless chucks and they get a major refresh when you replace the jaws. Your video is full of tips to give one the confidence to do the job. Warning; the jaws ain't cheap, but neither is precision! Btw, "quite arguably" as a phrase is, well, arguably quite wrong, lol.
Everyone hates burrs, but they're rarely a problem on well-used tools. Burrs are a bigger problem on new tools, often making them feel rough or even jamming. Sometimes an old tool will grow a burr on an edge that will actually interfere, but not often because that would be a poor design. Good video, well explained!
Thanks for this, gettin` me motivated to tackle a few around here.
If you have a surface grinder, what I do is grind some wrench flats on the body in the area right above the knurled hood. This allows you to grip the chuck in a vise for disassembly without the need to make a grip collar (that brass block that Jon made). For those who don't know, the steel is too hard to mill, you must use a surface grinder. --Doozer
Dude doesn't seem to know Scotch Brite is abrasive, so I wouldn't bet on him having a surface grinder...
Right On Doozer! 🙌 That’s a good tip. Make the maintenance nice and easy!
@@RightOnJonCrane I respect you not taking the bate. It was a pretty good video, and I definitely enjoyed learning about the chuck and how it operates. Thank you!
@@Jonainmi It seems you have a firm grasp on all manners of abrasive. --D
@@Jonainmi Not all Scotch Brite is abrades steel. Some will barely scratch plastic. The hardest one will lightly scratch soft steel, but will not scratch hardened tool steel.
I think I'll 3d print a couple of parts like you have made to simplify the process - like the bearing guide.
Nice overhaul instruction Jon, Well Done. The brass clamp is worth as much of the chuck.
Right On! 🙌Thanks Randy! You’re right! That brass ain’t cheap! Especially from McMaster!
Thanks Jon, an interesting series and a timely reminder that all machines require some maintenance once in a while !
Right On! 🙌Thanks Andy! yes this is leading me to clean up those Jacob’s chucks. It’s nice to have well maintained tools. Feels good once they are cleaned! 🧼
Well done video!! Nothing more you could have added, thanks
Right On Bill! 🙌 Thanks for your nice compliment!
Mr. Jon, I'll never need to do this but I enjoyed the video. Veey informative and well done.. Now the next set you have on the docket , I have one like that..just smaller I use on the wood lathe.. good stuff, makes me want to get a metal lathe and become a wanna b machinist 🤠👍
Right On! 🙌 Thanks Big Vic! Yeah those Jacob’s chucks are awesome. Great quality as well. I’ve got those on the bench and ready to go. Would be great if you got a metal lathe! 🙌
25:05 - Magic cutaway diagram of chuck shows the collar to be seated flush to the shell, with the corresponding amount of body-parallel sticking out of the top of the collar. If the collar does not sit 'lube-space-flat' to the top of the shell, wont that tend to reduce the rigidity of the chuck?
You’re right it does look like that in the pic but in my experience it does not affect the rigidity of the chuck. The Jacob’s taper is locked in. 🙌
$600 for this when I can buy a functional equivalent of this chuck for less than £20 from China!
Then I looked up Jacobs chuck removal wedge priced at $120 - a hundred quid or so!
I'll make my own wedges!
Very useful video nonetheless & it helped me unstick my bargain Chinese copy!
Right On! 🙌 Glad you got it unstuck! I do have some Chinese chucks as well! The Chinese quality is getting better. I’ve been surprised.
I can get the wedges for $20 on Amazon here in the states. For Jacob’s brand wedges.
Informative video which for me could be applied to other tools...🖖
Right On! 🙌 Thanks! Yes lots of little details about tuning up the surfaces that can be used on many tools. Thanks for watching!
Nice work . Very informative . Is it necessary to remove the arbor & collar to disassemble the chuck ?
It all depends what type arbor is in it. If it was a small straight shank arbor it could stay on but for an R-8 it has to come off if you want to slide the body out to get to the ball bearings. With a straight shank you could slide the collar off. That brass block I machined is a nice way to hold onto the shell of the chuck to open it up. Hope this helps. Right On! 🙌
Jacobs made a modern precision keyless chuck, I have two of them-
thanks for the lesson.
Right On! 🙌 Thanks for watching!
Thank you for the video. I recently purchased a used 1/32-1/2 Albrecht in good condition but when I took it apart to inspect and clean it, it had NO ball bearings...all gone...and quite a bit of grease everywhere...it was really sluggish to twist. After careful cleaning, it looks to be ok, amazing that it spun rather nicely on the machined surfaces. The ball races look undamaged and so I will need to acquire 25 balls. Do you know what size those balls are? Also, there is no marking on the taper end, but the "other" chuck that sold at the same time and was stated as the same size and had a box that showed "Nr. 130 B 16". I bought a B16 shank that seems to fit but would like to verify before "pounding" it in. I will try to measure the taper with a bore gage and calculate to see if it's close. Thanks again.
I have found that the balls are 4mm. They are available at several sites including McMaster, MSC, and Amazon. I opted for 316L Stainless from Amazon due to quick and free delivery. The taper was verified as B16 by measuring the diameter of the large opening and using a table of DIN and Jacobs tapers.
Many thanks
Right On! 🙌Thanks for watching and leaving a nice comment!
Great job!!
Right On! 🙌Thanks!
Great video!
Right On! 🙌Thanks Magdad! I’m sure Chuck liked this chuck video!
Amazing is that albrecht today basically has again higest precision stuff with apc.
I Have A Wen Chuck I Bought
Chuck For My 10 Inch Ryobi
Drill Press Will The Wen Chuck
Fit?
Possibly! Some of the Ryobi drill presses take a Jacob’s taper 33. You will have to look at your drill press chuck. It should have a marking on it. Match up the Jacob’s taper with the new chuck. Should fit great. Right On! 🙌
So the gripping surface of the jaw should be pointy with no flat at all? I am pulling mine apart at the moment and the first thing I noticed is that the jaws have quite some wear on the point, but I thought they might have a flat like lathe chuck jaws
If it’s a half inch chuck the jaw face should have a small flat and not pointy. If it was a smaller chuck the jaw face gets smaller to hold smaller bits. Right On! 🙌
@@RightOnJonCrane ahh I should’ve been wearing my glasses, I couldn’t see the flat!
Those green Scotch Brites are around 600 grit and will definitely scratch a polished surface.
My instructions from Albrecht specifically said to NOT lubricate the threads on the spindle. It needs to be dry for proper operation. YMMV
someone had trued up the taper on the arbor while mounted in the machine... making it smaller then and go in deeper... forgetting to shorten small end of arbor..
Hi Mike! I actually cut that taper off in my previous video where I slipped a puller over it to get the chuck off. That JT6 taper was strange that it went so far into the Albrecht chuck.
@@RightOnJonCrane no I meant the jt taper, not the r8
I have had one of this. I didn't know anything about, it had I MK1 Arbor and I didn't know how tow change it. I just give it away.
I am regretting now 😢😢😢😢😢
I hope another comes your way for a good price! You gave that one away. What goes around comes around. Maybe someone will give you one. 😁🙌
Tights come down and mites grow up ... a warning to us all ;
Right On! 🙌 Nice to hear another good saying!
was the jacobs taper that was too long made in china?
Most likely it was! I did not see any markings on it.
The original arbor that the chuck was mounted to was not a Bridgeport arbor.
JIM🎉
Right! It was some off brand deal!
😊
Right On! 🙌Thanks Lukas!
Good tutorial but, I think that you did not put enough grease on the bearings.
Right On Roger! 🙌 I do like to go minimal on the grease. Just enough to stop and corrosion.
I see many ignorant people putting a 1" step shank drill bit in these and ruining them. Also a hex shank hole saw will ruin them. These are precision tools. Not for blacksmiths or neanderthal machinists. --Doozer
I’ve never been a fan of those step shank bits! Whenever I see them they are usually chewed up where the chuck grips them from spinning.
It would be nice if some RUclips presenter would do an INTEGRAL SHANK Albrecht chuck teardown and reassembly. No such video exists.

Right On! 🙌 Yes! It’s been a while since I was in a cave but now I want to go and visit those caves in Sequoia National Park. 🏞️
thxs for sharing, say Hi to Moma Kitty...
Right On! 🙌 Thanks Tom! She says hello! 🐈
