Help needed for some advice....

Well hello everyone i am John...i am not new to watches...just to this forum...i have been on SCWF and Wrist Sushi for quite a while...i have asked around and no one has been able to give me any advice on my latest project....well i am putting a very nice Seiko 6105-8110 back together but somewhere along the way...someone damaged the case tube...and as most of your know...they claim that they are not repairable and case would have to be thrown away or what most people would do is a trip lock...which i personally dislike...one of the features is that unique crown...well i think i have done my due diligence and came up with a good solution...but i can not seem to find the correct way to accomplish this...here is what i am up against....here is the crown tube....

pic is borrowed from a friend on SCWF...this is far as i can tell the only pic of the infamous Seiko 6105 case tube...this one is from the 8000-8009 model but it is same but the 8110-8119 is just longer in the crown side....

here is a few more of what i am looking to build....

well my question to everyone and why i put this hear is ....i have figured this should be able to be made from stainless tubing like the originals and my thinking is that if i had the correct lathe...and the correct inner material to fit inside the tubing...i should in theory be able to replicate these...those who own lathes and have one...please let me know if i am right or wrong?...i have all the dimensions and i think i have even found the correct 4mm Od by 1.6mm Id tubing for the job....tube length  3,8 mm,  diameter outside 2,6 mm. inside 1,6 mm

 

any help will so be appreciated...

thanks in advance 

God Bless,John

sorry for the long thread...

This is a great project.  I've heard that those old Seiko tubes couldn't be replaced but always figured there must be a way if you had the right tools and a bit of talent.  I think someone else did the same job a while back and put together a document on it but I've long ago lost the links.

I did a similar job to a chronograph cases a while back which had stripped out threads for the pushers.  Like you I used stainless steel tubing and turned it down on a watchmakers lathe (Peerless 8mm).  It wasn't too much work but it did take time- the RPMs need to be kept low and a carbide graver worked the best.

well hello and appreciate the response....i figured i can not be the only one thinking about this...i know it would take a little work and set up....but would totally be worth it...might u remember who did this?...i do not have a lathe yet....not really sure which one to buy...i have used larger wood and metal lathe's....never one this size...and never even thought about owning one...but i like to fix things myself and if u have the tools...why not do it yourself...

truly appreciate the great info....carbide bit...low rpm's.....God Bless,John

I have been retired for many years. Back in the 70’s and 80’s you could buy these case tubes for buttons from suppliers, If you bought a new button for the case it came with a new tube.

What you have said and providing you have the tools and skill it will work.

Well thank u for the kind words...i think i need to find a good lathe...that will be key...i think i will practice on some cheap cases...if i make a mistake...better on them than my 6105....any recommendations on lathe for beginners?
God Bless,John

Is the pendant tube threaded inside for the crown to screw down onto, or does it screw against the small stud?
Should be easy to turn on a lathe. 
Well the tube is not screwed in nor does the crown screw down...from what i am told..it is press fit into.the case with some epoxy....my thinking it should be something easy for someone with a lathe...i am trying to find a lathe or someone willing to make me a few...appreciate the response...i think i have found the correct material with the correct 4mm od and the correct 1.6mm id...God Bless,John

The crown just is a press fit and that little stud just locks the crown once it is turned...not the best design for sure...but it works...i just want to return it back to how it was originally made...the crown gasket is quite stout and seals quite well...but the tube itself needs to be smooth and made correctly for everything to work as it should...most of the aftermarket parts people try and use will not work...that is why genuine parts and making the tube properly will be key

You shouldn’t have much difficulty in getting someone to do this if you can find the right person. If I had more time then I’d offer to do it, but I certainly don’t. 

It would be quite simple to make on the lathe with some rod.

    • Thank you so much, Hector and CJ. I appreciate the tech sheet and the video. Gasp, I think I will make the attempt. What's the worst that can happen? I think there may be a new balance complete in my future, though.  I'll update the post and let you know the result. R, Frank  
    • So here is the new base (v 2.1), I made it so that the base will fit over and swallow the stump of the hand pusher tool (or at least my clone of the tool), I also reduced the OD of the bottom skirt a little as it looked/felt a little large, here are a few pictures and the fake .pdf file which you need to convert to .zip once downloaded.   The cut-out seen on the below image on the bottom of the base should swallow the OD (40 mm, +0.1 mm tolerance) of the stump and the height of the stump 9.5mm (measured to 9.1mm, but rounded to 9.5mm) - let me know if this works for your tool.   Note, I think you may need to print supports for the new internal shelf created? Here is the fake .pdf for just the FreeCAD base file and 3mf files Modular Movement Holder.pdf Here is the fake pdf for complete set of the new base and ring FreeCAD/3mf files: Modular Movement Holder base and ring v 2.1.pdf However, I'm wondering how often you could use this feature, adding the dial usually increases the OD of the movement, so you would need a new (larger) adapter ring tuned to the OD of the dial and I wouldn't like to grip the dial in any kind of movement holder if It could be avoided for fear of damaging it. Maybe I'm misunderstanding you?
    • Hi Frank, you have dived headlong into the deep end. Hairspring work has to be the scariest thing a newbie has to tackle. Your hairspring appears to be bent and just putting it back into the regulator would not allow the balance to work properly. It might start oscillating but the performance would not be good. The proper thing to do is to unstud the hairspring, remove the hairspring from the balance, reinstall the hairspring on the stud carrier, reshape the endcurve and centre the collet to the balance jewel hole. This challenge would either make you or break you. Hope that you will be able to fix your watch. Welcome to the world of watchmaking.  Watch this video. It think it'll give you an idea of the task ahead. From your 1st photo, I think you have a etachron type stud. Let me see if I can find a video on how to remove it from the arm.
    • Have read of the Tech Sheet attached on the balance section page 12. It may be bent but until you reposition it back in the regulator pins you'll never know. Cheers CJ 4R35B_4R36A.pdf
    • Aloha All, My Seiko 4R35B movement stopped working today. Upon closer inspection, it looks like the balance spring came out of the regulator pin. This is my first time working on a balance. Any advice on how to get this spring repositioned (back to normal)? I'm pretty sure that while adjusting the beat error on this movement, I must have turned the stud (I didn't even know they turned), and the spring eventually fell out.  Will the spring go back to even spacing when it's back in the pin, or does it look bent? Thanks, Frank
