I’m servicing a Seiko 7s26c. Watching Marks video on this movement have helped tremendously.. but I’m having trouble installing the new balance on the balance cock. The hairspring stud is different than I’ve worked with before. I’m not sure how to get the stud into the forked stud “holder “. Beat regulator.

 

How do I get this “T” shaped stud into those forks? Pictures attached.

 

Thank you as always!IMG_1015.JPGIMG_1014.JPG

I had opened a discussion about that long time ago, it can be found easily. Anyway the outcome was nothing more than what the technical guide shows with pictures: balance and cock mounted in mov't, HS in regulator, use sturdy tweezers. 

It's needed that one practices with a junk balance, as is easy to do damage.

Thank you, JDM.  What would I search for to find the thread?  Is there a name for this type of stud or regulator type?

      DIY Cleaning Machine

      By Waggy · Posted

      I'm currently 3D printing a new basket and trays for my Pearl machine - I printed one last week in PETG material and it worked well at first. I had taken a calibration cube and soaked it in old cleaning fluid for 8 weeks and then measured it, and there was no discernable swelling or shrinkage and the cube seemed mechanically intact. All went well after the print and then onto the drying..... that's when things went awry. The heat was more than I was expecting and the basket and individual trays warped and deformed. I am now trying to print from nylon - which is extremely difficult to print with, my third attempt is chugging away now while I am at work - hopefully I don't go home to a ball of wool like last time!

      It is possible to true the pearl basket to run better takes a good hour of filing though.

      Waltham A-11 Hairspring and Balance assessment help needed.

      Yes, the general pat is this. On my diagram the points where the springs rises and levels are marked with red circles. This is only to show on all pictures (the ones that doesn't show this points as they are seen only from aside, not from above) where this points are. On You pictures, the pont where the spring rises is not marked. The point where it levels is marked with A. The point B is where the change in radius should start, but there is sharp bend there which should not be that sharp.

      I agree, very minimalist dial,  but then the diamond. The 1973 R has a black dial and gold case and is similar in layout. But on the MyBulova site there really is nothing else like it...

      This is such an odd Bulova. Off of the top of my head the only other mechanical Bulova that I can think of that has the 'Bulova' logo as an hour marker is the Golden Clipper 'J' (there must be others), one of my favorite dials. And then it has a solitary diamond, which is not unusual with Bulova, but paired with the 'Bulova' hour marker, that only leaves two quarter hour markers, and I can't think of another Bulova that has only two hour markers like that. You do you Bulova, no conformity here!
