Hello

I recently ordered, from Cousins, a winding stem for the FHF 175 movement I'm working on. It's listed as "Winding Stem (401), FHF 175 PN FHF175401" When I try and install it the end section is to large for the movement hole (see picture) and the section before the threads is very close to being to big for the channel before the winding pinion. This stem is a fraction to large. I'm not sure of Cousins return policy and since I live in Canada would it make much sense to ship it back? So do I take a file to the stem and try and customise it or order another stem? Ebay has an "FHF 401 WINDING STEM x1, TAP 9, CAL. 175 175-1 175-1-3 175-3 (NOS) watch parts" that's 10.5mm long (I assume that's what the 10 1/2 stands for). The stem I got from Cousins is 18.5mm long. Ranfft lists the "Stem W842 (10.5'''), W875 (11.5''')", so perhaps my best bet is to order the replacement from ebay.  I'm seeking the advice of the experts in this group to see if someone else has run into a similar issue.

Thanks in advance for any help that can be provided.

You are not the only one getting such "roughly" finished Stems. I had to file mine as well due to exact same issue.

That's what I expected (right side) and what was shipped (on the left side) ?

 

Sorry, forgot to add: O Canada... ?

To reduce any circular section, mimic a lathe.

Mount the stem in a pin vice" your lathe", cut a piece of sandpaper as wide as the section to be reduced and bend it in the midle to shape a "V", grab the V shaped sandpaper in tweezers "V"  sandwich the section to be reduced inside the "V" eed sand paper and turn the vice.

Advantages are even reduction form both sides of the circle you are reducing the diameter of.

The piece comes out nearly polished.

This homemade lathe is also handy to increase diameter of the hole into which the stem end is to enter.

I did post a pictorial of this approach, its obviously tranfered to amazon cloud, can't search it.

Yes you can. While writing a posting click "Other Media" bottom right, "Insert existing attachment" is presently the only choice. Then enter a portion of the filename if you know it, or browse all the thumbnails.

      Calendar work certina 25-651

      By tonydagee · Posted

      Hello all, just disassembling to service, but I can’t figure out the working of the calendar work…it’s not operational the jumper and spring are ok, but the operation of the driving wheel has me at a loss. I can’t see a cam to drive anything. Is something damaged or missing? Help please!

      Unusual Seiko dial damage

      Believe the relume (not a fan) was done a long time after the damage.

      A lathe with indexing that won't break the bank?

      By nickelsilver · Posted

      I have a little milling attachment for my WW lathe, but very rarely use it and not for wheel and pinion cutting. For that I use a small Sixis 101 milling machine. I normally do direct dividing, but sometimes have to do an odd count and use the universal index which also fits on the Sixis.   Back in the day when I didn't have a mill, I would cut gearing on my Schaublin 102. It has a universal dividing attachment which fits the back of the spindle. Both it and the one for the Sixis are 60:1 ratio, and with the set of 4  index plates I can do almost any division. When I've had to do a strange high count prime number, I print a disc with the needed division and just place the plunger on the dot. Any position error is reduced by a factor of 60 so still plenty accurate.   The machines are a mess in the pics as I'm in the process of making a batch of barrels for a wristwatch 🙃.   This is the Sixis. The head can also be placed vertically, as can the dividing spindle.   Dividing plates. The smaller ones fit another dividing spindle.   Universal divider for the Sixis. I put it together with parts from an odd Sixis spindle that takes w20 collets, like the Schaublin 102, and a dividing attachment from a Schaublin mill.     The dividing attachment for the 102. The gear fits in place of the handwheel at the back of the headstock.   And the little milling attachment for the WW lathe. I just set it on the slide rest to illustrate the size, you can see from the dust on it it really doesn't get used much. I think only when I change bearing in the head, to kiss the collet head seat (grinding wheel still in the milling attachment).

      Opinions on Seiko's 4R and 6R movement quality from those more able to judge

      By SidKop · Posted

      I read a lot about the quality (or lack thereof) of Seiko's 4R, 6R, 8L  movements...or more specifically the lack of regulation from the factory. Especially when compared to similar priced manufactures using SW200's or ETA's. I thought I'd ask those more in the know, do the 4R's and 6R's deserve their bad reputation, is it fairly easy for someone with minimal skills (or better yet a trained watch mechanic) to dial in these movements to a more acceptable performance.    For background I spent more on a 1861 Speedy years ago, expecting that the advertised 0-15s/d  would probably perform more like 5-7s/d. In reality it's been closed to 2-4s/d.
