- I replace a balance staff on a Hamilton 992B. This was easy compared to the Illinois I did last year because it has a friction fit balance staff. Push out the old one and push in the new one. Very easy. There are a couple of mistakes in this video but since it took so long for youtube to tell me why it would not upload I forgot the mistakes. I have been trying since March 18, 2013 to upload this video. A couple of days ago they finally told me to try again because the video was the problem. Better late than never I guess.
This video performed by an amateur. Do not attempt at home. No watches were harmed in the making of this video. For entertainment only.
I don't reply to negative comments anymore. If they think that they can do better or that I am doing it wrong then let them make a video and show me.
Thanks Bunns
I bought staking set, complete set and your video help me a lot for understanding how to operate it .
I like your personality, plus your giving us your time. Blessing to you
I've got 25 years into this pocket watch repair. I perfectly understand the language. I'm a retired Navy Master Chief/Master Diver so foul language doesn't bother me one bit.

Thanks for watching. You are not giving me much to go on. After it runs for an hour and stops can you get it started again? Is the balance staff good? Maybe the hands touch. Maybe it needs to be cleaned and oiled.
I just purchased a K&D 18R Inverto and this video was so helpful! Keep up the great work!
Glad it helped! I have some other videos using this staking set.
I like your videos. I am just starting tinkering myself. I always do my research first but a lot is from experience... so I cant wait till I get better at methods. I wouldn't worry about comments. they made watches before 1900 that last a long time without the technology we have today, with the same basic hand tools. Please.. keep posting more videos. they definitely help me out!!
You know, I too have a fully functional full silver Anker Pocket Watch from 1910 that is guaranteed to function 70 years from now with the revision that has been made on it. Seeing all those people commenting negative stuff about your video and your way of work pisses me off. Even though you may be an amateur, you end up repairing them eventually and that is NOT BAD, you should study and try to be a master at this. You have the knowledge. Congrats! From a watch lover to another watch lover.
I believe they being negative because the way he speaks in the video. To be fair, it's kinda annoying for me to listen. He is handy and a good amateur watchmaker too. I just bought a complete set of staking set tools. This video will be handy for me
Another great video, and I thought you did a great job! I can certainly understand your frustration with the small parts and especially trying to get the hairspring stud into the balance cock hole when it's off the watch. What a pain!
Thanks for another good lesson for us amateurs!
Great to see ya back!! I really enjoy watching your vids
thanks Bunn!!! cool video as always, keep em coming
On this set the large dial on the back tightens the table. The large dial is attached to a shaft with a eccentric portion. There is a rod that is threaded into the table on one end and has a hole for the eccentric on the other end. When you rotate the large dial the eccentric pulls down on the threaded rod to pull down the table. Sometimes I rotate the table to much in one direction raising it to high for the eccentric to pull it down onto the staking set.
welcome back,missed you keep em coming please
Great video, many thanks
Sounds like Quentin Tarantino directs a watch repair. You sound like Joe Pantoliano.
I have a K&D inverto 18 set, and yes the large dial on the back tightens the table (like all staking sets I suppose), but that threaded rod you talk about from underneath (with a screw on its head in my set) is where you can adjust how much the dial from the back to tighten (at least this is how it works on my set). I had the same problem as you and I found this to adjust the tighten and solve my problem. Hope this will help.
I’m so sorry if someone has already asked this, but what striking set do you use? I’ve been trying to find that style but with no luck
I used a K&D staking set. I have a video showing the rusty state is was in when I got it.
Demm screws...! Very nice video !
Love your videos!
Yay! He's back!
Thanks for the video.
hi there Bunn! love your videos! is the staking set you're using the K&D #18 i've been seeing on FleaBay for a bunch of $$$? did you manage to find a set with all the pieces? seems like a good set to own for putting in new balance staves. Did you just order the corresponding staff or had to measure?
My staking set cost 50 USD because it is missing some tools and it was covered in surface rust. It took me a week to clean it up. I agree a nice set cost $$$ but for what I do this one works. I ordered the staff because there are still a lot of them out there.
Good stuff thanks!
Thanks so much for making this video. I learned alot. I inherited my GGrandfathers 1895 Elgin Hunter case pocket watch. It doesn't run. Thanks to your video I see what's wrong with it. What would you guess a watch repairman will charge me for this repair? BTW, I was wondering if you searched for broken piece of metal pivot. Seems like it has to be somewhere in the watch case. Thanks again
Before I started fixing my own watches I did have a couple of staffs replaced but I can't remember what it cost. Sometimes you find the broken piece still in the hole jewel but I don't remember if I found it for this watch.
Great job so what happened to the broken pivot end? And how would you like to replace a pivot on a verge balance staff for a miniature French verge fuse pocket watch. 😁
I don't remember. Either I pulled it out of the jewel or it disappeared into the watch. Don't have the tools or the skill to replace pivots, just staffs.
Brilliant video. Like watch Tinkerer I would like to know where you get your balance staffs from. I have an old Lancashire watch Company Prestcott full hunter with a broken balance staff and a damaged jewel. I would love to get it going again but cannot source the parts.
I look on ebay for staffs. There is a watch supply source on the internet that sells staffs for old pocket watches, can't remember the name, but they only carry the big names like Hamilton, Waltham, Elgin, etc. Some one put out a book listing many staffs by size in hopes that one could find a staff that is close enough to use or alter for use.
Do you ever have problems with the hole widening? So I'm replacing a staff on a BW Raymond and had no problem popping the old one out with my staking tools, but when attempting to put the new one in place there is a lack of friction like the hole got wider when I punched the old one out.. so it just falls out. I checked by putting the old staff back in and the hole definitely got wider because it falls out as well. Any suggestions?
I once replaced a staff and the hole was smaller. I think it is a tolerance thing. This stuff was mass produced. When you mass produce you have a tolerance, every item is not the exact same size. How loose is it? Maybe when you rivet it the staff will expand to make it tight.
Great Video, how can you tell if the staff is bad?
Well if the watch don't work is the first sign. Another possible one is if the watch only runs in one position. My favorite one is a wobbly balance. But the best way is to examine the balance staff. Also you should check for broken jewels while you are looking at the balance staff. I did a video on this question you posed. Check it out if you like.
Hey Bunn what type of movement holder is that? Bergeon 30211?
Albert A No. I got it at the NAWCC museum. Looks kind of home made.
Is Melamine some type of enamel? I have seen the term before but never knew what it meant.
It is a type of plastic. The problem with this type of dial is that it cracks and then could flake off the base. Look on ebay and you will see what could happen to this dial after 50 years.
Thank you bunn for responding I learned something new today.
YES ! It's been a while
Excellent video again. I notice a lot of you viewers asked about the balance staff holder. I too am looking for this attachment. I cannot find it on e bay. I did purchase a stacking tool, however this item was not provided. It is the same stacking tool your using. when I research the rex roller remover it is quite different. Hoping someone can help.
What do you mean by balance staff holder? Where in the video do I show this?
I was referring to your below statement: The Rex Roller Remover is much different then the one your using is all.
bunnspecial9 months ago
+Alberto Alburquerque Reus I think what you are writing about is called a roller remover. Bought one on ebay and my staking set also came with one. It is also called a Rex Roller Remover.
Okay. I think I show the roller remover I first bought on my tools I use video. I have also see the squeeze type.
The attaching tool I'm refer to is this one picture you sent:
It has the friction levers to help hold the balance wheel in place on the stacking tool anvil. If you know where I could get one let me know. Thanks Jim
Are all friction fit balance staffs blue?
The balance staff is not blue the hub is. The hub is riveted to the balance and they blue it so you know not to remove the hub because it is a friction fit staff. I don't know if the other companies all did it that way.
When did Hamilton go to friction fit staffs?
I am not sure. I know they use them on the 992b, 950b and other watches based on those. Also the 10 size watches. I think they may have started with the 992E and 950E. Those were made in the late thirties. It is a joy to replace those staffs. I have also seen them on Waltham and Howard (Keystone).
This is a Good video, not that it effects the functionality of the staking main plate but try some 1500 grit wet sand paper but instead of water use 3 in one oil and put a few drops on the plate and sand in a circular motion (wrap the sand paper around a small block of wood or something small and flat) you may not get all the rust stains out but the plate will other wise polish up nicely, wipe with a clothe when done, maybe you could do a video on watch tool maintenance, IE dressing screw driver tips etc; what do you think?
That is a good idea to clean up the plate I will have to try it. I do have a video showing screw driver tip dressing.
@@bunnspecial I will have to look it up
Hello. Great video. How do you call the piece you use to fit the balance wheel in to take out the roller? I bought a stacking set separately (machine, punches) but I cannot find these pieces that usually come in the set. Thank you.
+Alberto Alburquerque Reus I think what you are writing about is called a roller remover. Bought one on ebay and my staking set also came with one. It is also called a Rex Roller Remover.
+bunnspecial yes I've seen the roller removers that look like a scissor for 10 bucks but as I purchased a staking machine I thought it'll be easier to use it to remove the roller like you're doing in your video. I guess I'll have to buy these type of "platforms" from a staking set sold separately... Or just use the "scissor" roller remover. Thank you!
To bad they didn't have incabloc, kif, or diashock back then. Breguette had a crude system using a loop system with a hole that holds the jewel in place on the balance bridge. It illiminated balance staff breakage ( not completely) but did the trick somewhat. I should retrofit a shock system like that to vintage pre 1948 pocket watches.
Awesome video! Another very informative in the series. Thank you for all your videos which have been extremely helpful to an amateur such as myself, who is just beginning.
Is Hamilton the only friction fit staff?
No. Waltham and Howard (Keystone). There may be others.
fantastic its been some time since your last video i thought that you had stop working on watches please continue to make some more. How about making one on truing a balance wheel best wishers ady
Ya I like them to ignore all of the negative comments and keep making those vids
Did you make those hand levers?
Yes.
Hi,
There is a screw underneath your staking set to adjust the tighten of the table ;)
Alex
nice watch
How can tell whether it is a friction fit or riveted type staff?
The hub is usually blued. I think you can see that in this video. Also if you do some research you can find out.
Where did you get the new balance staff from?
Ebay.
the balance staffs for 992B is it the same for 950B and 950 #659

Hola los ejes no deberían ser extraídos sin antes quitar el remache, de esta manera se abre el centro del volante, y con el nuevo eje no podrá ajustarse debidamente, el aro de volante se descompensara, un saludo Antonio Varela, maestro Relojero
Thank you for your comment. We here at Bunnspecial studios read all the comments and take them into consideration when making videos.
Sol Rosenberg does watch repair!
Have you now acquired a roller remover? Best Wishes
Yes.
What makes a 992B different from a 992?
Whole new design.
I have a montandon pocket watch and it works but stops after an hour do you know why and can you do a vid on one I love ur videos and im 13
The wobble of death💀

bunnspecial 🤣 Or if your a Prius fan the red triangle 🔺 of death 💀
The pocket watck is key wound...
Tenho uma desta para vender em bom estado de conservação
Show me a picture.

Sir I was also in watch repairing job but you took lot of time to fix this balance staff it just a 10 minutes work your video is too long
I agree. In fact I just replaced a staff like this in 15 minutes. I wish I could show you but I didn't make a video. That is why it took only 15 minutes.
You have alot of watches so You know alot about watches? Then in this case im an expert becouse i have few hundreds of them. My father is a watchmaker and im learning to be one, so trust me (or him) when i say: 'timex is a chinese/philippnes piece of crap'. If You want to make a request feel free but i would rather like to watch how he fixes some nice quality swiss, u.s or even russian watches.
iLlinois watch
Unfortunately the blunders wouldn't inspire me to get you to fix my watch - sorry
Jerry Lawrence Don't be sorry. I did not make this video or any video to have people send me their watches to fix. As the description says "For entertainment only".
He does moan a bit..lol
Wrong proses.
so slow tortise
OK, I've been watching this fellows videos and all the cussing and blaming his problems on inanimate objects when he needs to be more careful. Take up another hobby if it's so stressful or try to be more organized and less careless.
Or maybe you shouldn't be sensitive lol
Bunn's running commentary is priceless...and his "mis-steps" (if you can even call them that) reinforce the point that being successful doesn't require absolute perfection. His videos gave me the confidence to even try to work on these mechanical marvels...and I get better with each new project.
Bunn provides endless entertainment while theaching for the "everyman". Always look forward to his next installment....
....and no, I'm not related...HA!
My balance shaft is broken too. But I do not have a staking device. Is it possible for someone else to fix/make a complete one with wheel and spring already balanced and poised. And I install it in my watch is that possible or does one need the watch
It is possible but I see some possible problems. Since you might not know the repair history of the watch the replacement staff may be to long or to short. The staff may have been replaced in the past with one not quite correct so the watch was altered to fit the replacement staff. Another problem is when the hairspring is put back on it might not be in the correct position making the watch out of beat. The watch can only be put into beat with the balance installed.
thanks for the video,great help for me . I even loved all the personal frustration...crap crap crap. I am glad you took the time to video. Keep it up .
Thanks you lam I learned a lot from you

Glad to hear that but like I say in the beginning 'this video is for entertainment only'. Learning is an off label use of this video.
Also that hairspring is Elinvar type. That is why it looks different from your average Breguet type hairspring. Elinvar hairsprings make watches more valuable.
Sebastian, I would guess that it is most proberly in need of a clean (this is usually the case) but there can be lots and lots of other problems that are making the watch stop. Maby take it to a watchmaker so he can tell you what is wrong with it.
Fouled anchors and decent lines do however.
