It is the first time I have come into contact with a balance cock that is not screwed together or inca block type of jewel attachment.

Is the balance/jewel/adjustment pressed together or is it threaded together? 

Any tips are very welcome.

Thanks in advanced.

(oh my, how I had hoped to find two small screws on the underside of the cock)

There appears to be three notches on the underside of the balance cock around the jewel.  My guess is that a KIF tool might fit that, and it would screw/twist off.

Yes, the ultrasonic is your best friend in this situation. Whatever you do, DO NOT peg that hole.

Thls is a non-removable jewel setting. The 3 notches are to allow the cleaning fluid to penetrate and wash out any debris.

This is the first time I've seen it being used for a balance jewel. It does not offer any shock resistance to the balance pivots. It's normally used for the escape wheel and pallet fork jewels.

I have some ordinary balance jewel settings like this I'll pull one apart, it was fitted together somehow.

Ok so i found some to play with.....because I'm kind of awesome like that, shall we have a look to see if they come apart ?........easily without the use of the equaliser ? 

 

I think Nev should make me this from a crushed car engine......... to go with my spandex outfit.

Before i start, I'll point out that i agree with hector about solutions flowing through the setting, not so obvious in your photo but my first victim has 3 finer slots in the top , i think i can see yours also has these.

If it's non removable how would you replace the regulator?

So if you really want to you can break the cock and jewel setting down to these 4 pieces, the regulator arms remove quite easily with a sharp knife under the beat arm then the setting can also be prised out from the cock with the same sharp knife. Thats about as far as you'll get and tbh i dont think you need to go any further the US should flush it out, so I'll  try that. But for interest there does look like a fine seam that will split the jewels holder in two and yes the jewels are seperate....a holed and a cap...the cap is a tad wider as usual. Lets give it a blast in the US and see how it comes out...this one is grubby as hell and the jewel hole is block...so a little poking around is required to free up the crap. To summarise....dont bother stripping it down even to the 4 parts unless you're really fussed about it, just blast it in a USM. Let us know about your outcome with it please.

Yes it comes apart Andy..... to 4 pieces 

I'll flush it, and then try split the jewel holder, 99.9 % sure it wont survive, the equaliser is ready and waiting to take over when it goes pear shaped 🤣

Thanks a ton for the disassembly test. Very value information. I will now put it into my USM and lubricate it with an automatic oiler.

Wow!! What a great forum. Waking up early morning loaded with many good answers to my question.

It feels very inspiring to continue with the movement.

Thank you all!!!!

Yes, that was my first thought too. Due to the notches.

I only disassembled that one, but the rest of the examples seemed pretty much the same setup. The jewel holder itself will not split without some specialist tools. It cleaned out ok, you might need to swish it out a few times to get it really clean, uou could try  injection with solutions....like a mini jet wash 😅

Here's what I'd use 😅

Yeah , i think that probe end would be a fair whack bigger for what you imagined Andy 🤣

      Oiling Dubois Depraz chrono module pivots (Omega Speedmaster Reduced)

      By Simeon · Posted

      Righty ho, I re-serviced the chrono module and got a reasonable result with minimal loss of amplitude when not running the chrono and about 30 degrees loss when running. Great. The problem is now that the chrono (and movement) stops running after about a minute or so, a tap on the watch starts it running again. No issues with the movement running when the chrono is stopped. Going to service it yet again, obviously some residual issues with friction in the chrono module (Very frustrating - I wish there was some way of testing it as I go!) I also seem to have a problem with the cannon pinion where the movement is running continuously (with the chrono stopped) but it's losing significant time / stopping. This is one of those two piece ETA style with a driving wheel pressed over the cannon pinion, obviously arranged for driving the chrono module. I had no issues with this prior to service and just added a small amount of grease between the driving wheel and the centre cannon pinion as the technical guide required. What's the best way of tightening these up? I would like to replace it but I guess this is going to be hard to find as it is dedicated to the DD chrono movement.

      He uses the micrometer cap, but he leaves the spring out (you can see that in the video). If you leave the spring in, the spindle will move up as well (as shown by @Knebo).

      Seems like he doesn't have the micrometer cap  attached to the spindle so he can only push down but cannot pull up? If the cap screws into the spindle I guess you don't need the spring? I only have a "normal" Seitz so I really have no idea.

      Lathe motor advice

      By Dell · Posted

      Yes in my opinion the 3/4HP is plenty but it’s your decision & yes it does come with speed control but foot operation so my reason for changing to potentiometer was because my leg shakes so it was like me revving the lathe & anyway I prefer to set the speed. I & a few others that I recommended the motor to run a Pultra 10mm lathe so if you have a 6 or 8mm B & L then it will be plenty, if you have seen any of my videos you will have seen that when using a graver I run quite slow without any problems.
