My Jacob's chuck was binding up at frequently when I tightened or loosened it. I followed your video to disassemble it and found - drum roll - attached chips at the break-through from drilling the jaw holes. When the drill or mill that was used during manufacture broke through at a great angle, it left some attached chips that were never removed. When tightening, a jaw tooth would bend the chips into the hole and the next tooth would wedge against it. All three angled holes had these chips. Poor quality control. After removing the chips it works great. Thanks for the video.

I got a 0-3/8 Jacobs chuck in a bunch of neat stuff but I couldn't move the jaws. I watched the video twice & downloaded the online instructions. Everything went down as shown; Only 1 jaw was tight and a few light taps & clean/re-lubricate, Went back together nicely in my #1 Dake arbor press. Life is good.

The bolt that attaches to the camera (and is found on most tripods etc) is : 1/4" 20tpi UNC. In the past it was a 1/4" 20tpi BSW but at some point someone decided to create a standard and use UNC instead. Most likely so they could charge you to buy a copy of their "standard". Here are some terms : tpi - Threads per inch BSW - British Standard Whitworth UNC - Unified Thread System Larger equipment sometimes uses : 3/8" 16tpi BSW and UNC? As mentioned above BSW stands for "British Standard Whitworth" and was introduced in 1841. UNC stands for "Unified Thread System" and was introduced in 1918. The number of threads per inch may be the same BUT the thread angle is different. BSW thread angle 55 degrees UNC thread angle 60 degrees Apparently a 1/4" UNC bolt will fit a 1/4" BSW nut (or camera shoe) despite the thread angle difference. For camera equipment the screw length is fairly short so the thread angle doesn't make much difference.

I enjoyed the video. I have never seen a chuck pulled apart before.. I had a lathe tail stock chuck that was so bell mouthed as to be almost useless. I had nothing to loose so I put the chuck in the tail stock and a fine chain saw file in a collet in the headstock. I then brought the chuck up to the file and while the file was turning slowly I brought the jaws of the chuck together around the file. It instantly removed the bell mouth and eliminated almost all the run out. The only down side is that I lost the ability to chuck up very small drill bits but I can live with that. The chuck has been working well for years.

+Fred Miller precisely what I thought. I have a round(and very fine) diamond file that would solve the problem in a minute without disassembling the chuck or losing a ton of time making those repairs. Frankly I don't think this chuck would be used for any precise work and the file solution can make it better than with the original parts, which would not solve any other accumulated wear issues.. About the very small bits.. first they would not be used in such a chuck.. and second you can use another mini chuck (like hex for electric screwdriver) to handle those by attaching it to the larger one chuck.

Extremely informative for the rebuild. And the threaded nut is broken because if they cut it the thickness of the saw blade (material) would be missing once put back together. what they do is drill it on opposite sides the hit it with a hammer and break it. once back together it a perfect threaded nut, also contained by the outer casing.

I have observed when rebuilding a jacobs chuck with damage to the face from hammer blows, the tapered ways the jaws travel in will be distorted more than you would think. it pays to do some careful observation before assembling in the outer end of the jaw ways for even small amounts of raised metal, you could have probably reduced the chuck runout some more. That was a good video keep up the good work!

I loved the video, but I have 3 points to say. 1. Why do you want the jaws halfway when disassembling? I really did not get your point when you explained it. On the other hand, I do believe that moving the jaws back just enough to be behind the top of the chuck so that you rest on that top when pressing on the rear of the cover, in that case, I am assuming that instead of pressing on the jaw's teeth, we are pressing on the back of the jaws because of the taper they have on their backs. It might take some time to think about it. 2. For the assembly, I think it is better to make the jaws all the way to the back. In that case, when you press you are pressing on the jaws end, hitting on their end of travel (housing) again instead of pressing on their teeth. Think about it also. 3. The last point, I want to say that I really don't think that there are 3 mating surfaces (tight fits) for the cover with the chuck body. I think only the 2 halves are against the cover. Correct me if I am wrong. Thanks.

HF press is about the same as any... need support at the front end to resist pull on the handle and support the workpiece so the press base doesn't break. You can also cut down the runout a bit if you LIGHTLY tap on the pin as you snug, and walk the chuck key around the three holes as you tighten. The key will pull the collar and the ring off center, bringing the jaws off as well.

Per ISO 1222:2010,[1] the current tripod screw thread standard for attaching the camera calls for a 1/4-20 UNC[2] or 3/8-16 UNC thread.[3] Most consumer cameras are fitted with 1/4-20 UNC threads. Larger, professional cameras and lenses may be fitted with 3/8-16 UNC threads, plus a removable 1/4-20 UNC adapter, allowing them to be mounted on a tripod using either standard. Historically, The Royal Photographic Society recommended the thread standard for attaching older cameras to tripods was 3/16-24 [(British Standard Whitworth)BSW] 3/16 inch nominal diameter, 24 threads per inch, or 1/4-20 BSW[4] for smaller cameras and 3/8-16 BSW[5] for larger cameras and pan/tilt heads. In this application the BSW and UNC thread profiles are similar enough that one can mount a modern camera on a legacy tripod and vice versa. The UNC threads are 60 degree angle and flattened, whereas the BSW are 55 degree angle and rounded crest. However, at least one English manufacturer uses No.1 B.A. (British Association) for its tripod mount thread.

Another great video. Last year before I got into this metal working and lathe business, I was working on a wood lathe making pens and bowls. Well, I had a Jacobs chuck on my drill press that failed on me. I took it off and somehow managed to get it apart. The first thing I noticed, was that broken nut and I still remember saying to myself, Ah hah !, that's what caused it to fail. There is now way I can repair that and put it back together. No sense keeping this thing and threw it into the junk and bought another chuck. Arrrrrrg, what have I done. Oh well, live and learn. Sure wished I had kept the chuck and now with your video, I know I could have saved that chuck. I just hope that chuck found it's way to chuck heaven. Great teaching technique, you make it look doable. I was surprised to see that arbor press work as well as it did. I recently bought a similar press at Harbor Freight. Now I need a good project to use it on. That chuck would have been nice ;-) . Ken

mountain out of a mole hill. Yes, you need to put the jaws back in the right place (mark em w/ a sharpie) Lower the jaws so they are even w/ the body. Align the outer gear sleeve between the jaws of a vise and hit the body & jaws w/ a BFH. The body & jaws will slide out between the vise jaws. BFH = big effing hammer. On the install put the jaws back where they belong bottomed out on the body, put the new 2 piece gear on & slide the sleeve down as far as you can. Now get a impact socket that will accept the body and w/ a smaller hammer drive it all together.

If you machined the taper yourself it's just due to variation in wear on the tapers. If you matched it to one it may not fit the same in another. If it's a purchased taper shank then it may be the tang. SB have no tang slot so you have to extend the quill ~1/4" to get it to seat.

I'm only beginner machinist, so this may sound crazy. Why not snug the chuck fully closed, put it in the tool holder, adjust until the runout is as small as possible, chuck a bit in the lathe, and drill a slightly larger diameter hole than is already there through the jaws? In my thinking, this would at least create reference edges that are parallel to each other, provided the jaws are machined well from the factory. With any appreciable pressure on the jaws, they should remain in contact with a bit on all of those edges. You would reduce its overall clamping friction and be unable to use bits smaller than the one you used to create the edges, but this seems like a fair tradeoff for higher accuracy, especially since you mentioned you would primarily use it for larger bits anyway. Would this be a solution at all?

Without reading all the comments; I'd suggest that 'freezing' the 'innards' of the chuck , then heating the outer ring would allow it to be pressed together very easily ! ? Very nice to see a great example for the use of Buttress threads . . . I wonder if it would be worthwhile to attempt reconditioning the old 'jaws'. . . 'possibly build another chuck with them ? ( It would be educational ! ) ;) Good work ! . . . As a final thought : since you changed the bearing surfaces ( split nut & jaws) you must have realized that if you don't tighten all 3 jaws, there is the potential error of the split nut NOT ENGAGING 1/2 the diameter . . . which would 'cock' the tool . . . *indicator stem, or whatever is 'partially' chucked up ! (( the split nut isn't quite as accurate as a 3 jaw scroll chuck 'could be' - ** supposing that it all depends on how closely the grinder work was done ! )) Study of mechanisms & their shortcomings will eventually lead to better engineering ;) ! . . . Once an adept mind can see inside the hidden aspects of what make things 'work' !

For a clean newish chuck there is no reason to hesitate in doing so, but for a dirty and ceased chuck it can cause the screw or jaws to chip.

P.S. for what it's worth, on my 33B Jacobs Chuck, which I was able to put the jaws all the way in / down, then pressed it out with no problem, and no press, just used a old socket I had laying around, and the all mighty ball peen hammer, with some scrap aluminum to protect the face, just hit it out, no big deal.

Perhaps, you could mark the direction of error, and lap off some of the body grooves--say two grooves lapped out .002 inch each to relocate a .005 runout. Just the right diameter rod and some 400 paper might do it. Tedious trial and error, but pre-calculated it might get it in one try. You'd almost have to guess the amounts removed, but measurement might be possible at the front.

Yes, do take it apart; even if you don't have a rebuild kit, the removal of old grease and trapped shavings can fix a balky chuck. It is also important to have a clear bore for each of the round teeth to slide in, a dented bore can jam one tooth. Drill bit worked by hand can find and clear a minor ding.

Manufactured with notches and deliberately broken at that point to be able to install. You did not break it.

I recently acquired a Walker Turner 15" drill press with a Jacob's chuck that was seized and after soaking it in Mineral spirits for 3 days and WD-40 for half a day I finally have it unstuck. My question is what type of press are you using to take the chuck apart?

Thank you, I just looked it up and for 60 bucks it might take me a bit until I can get one. I have however cleaned the press so that it works properly, I won't be able to restore it for some time due to a lack of funds but I hope to use it as soon as possible. I am only 19 but seeing such an old machine now in a better state than I found it makes a smile come to my face.

right on i know the feeling. even polishing metal to a new finish is a surprisingly satisfying feeling. I was excited when he mentioned the press, for $30, of course it seems to go for twice that. I keep hearing of great deals from Harbor Frieght, but alas those deals seemed to be over with when I catch wind. I think the trick is to check in your local store as they may push certain merchandise to clear stock.

Never shop at HF without a 20 or 25% off coupon. Print them out online and they're usually in all kinds of magazines and flyers.
