Favorite staking set question

Hi,

I've just bought a second hand Favorite staking set and have found that the pin vice doesn't fit into the staking tool bore. This appears to be due to a small pin partway up the shank of the pin vice being about 0.1mm proud of the surface. Now, being a bit new to this I assume that the pin vice is for holding reamers and the such like and having the reamer about an inch above any workpiece isn't too useful. I thought I'd have a check here before I remove the proud part of the pin that the problem I have is actually a problem. I assume that the pin is to hold some part of the internal mechanism of the pin vice and not a design feature.

Anyway, does anyone else have a favorite staking set and can they confirm that the pin vice fits all the way down the bore?

 

TIA

Yes, I went for this set as it has the jewelling feature. The lever comes off if you want to work without it. I've just seen that Mark has used this set in one of his videos and it does appear that when he used the pin vice it fits all he way as you'd expect. I think I'll adjust the pin...

This pin is for preventing the conical collet from rotating while fixing the reamer with the drowbar. This system is identical to the one seen in watchmakers lathe. You should push this pin inside to get it flush with outer shank surface. The pin must protrude inside of the shank in order to fix the collet. You should have a couple of collets of different diameters in ths set.

Ah, Thanks for the information. I thought the pin was for some purpose like that but it's nice to have confirmation. I've taken what was probably 0.01mm off the pin on the outside and all is well now. Yes, I do have a few collets. One more than I have holes for collets, actually, so one of them is an extra I think.

      About repair watch's jewel.

      By jhoho202 · Posted

      First of all, thank you for the pdf file of the book on how to replace a gem. So, if there is a problem with the ruby in the movement, should I buy a new or used movement and replace it? When I watch videos on YouTube of people fixing used watches, I feel like there should be a way to buy a gem. Is there no way to buy it?

      Parts sourcing for FHF 180 movement

      By praezis · Posted

      I suppose @donutdan is not forced to earn his living by repairing watches.  I suppose he does it as a hobby and wants to gain experience, to get better in watchmaking and time is not the issue. Then @donutdan should rather try to repair the damage instead of swap parts from a maybe intact other movement. Swapping parts is not watchmaking. And often swapped parts are not the expected solution of all problems. All mentioned damages are repairable. Frank

      Yeah I figured that one out when I googled and realized that my spindle is actually from Horia. It's smooth with no screwable cap.

      I am puzzled by something a snipped out something from your image and what exactly disassemble tell us? my confusion is the symbol for FHF looks like image I have below year symbol as a star and righted this instant are not finding what that means? I suppose we could use the fingerprint system to verify it really is what it claimed to be. Size itself is really interesting there's almost no watches in that particular size. Then were missing details in the photograph above like diameter of movements to verify it really is the size and are missing the setting components.   went to the bestfit book looking at the symbols didn't see it. Look at the link below I did find it back to the bestfit book and yes it really is there https://reference.grail-watch.com/documents/history-of-ebauches-sa/ then bestfit book says lists the size as 10 1/2. one of the problems with vintage watches is finding parts yes a donor watch would be good.

      Oiling Dubois Depraz chrono module pivots (Omega Speedmaster Reduced)

      By Simeon · Posted

      Actually, this could be the issue. Drag from the module could be overcoming the cannon pinion. It was definitely not at the point that the driving wheel was loose on the cannon pinion, it took a little bit of effort to rotate it when applying the grease. Maybe I need to look again at applying oil to the pivots.    Yeah, it's very annoying. I don't want to give up on it, so back on with it over again until I catch a break.
