Cheers Mates!

This time Im working on a Baumgartner 582, Buler Aeromaster.

Watch did not work because the impulse stone or finger was on the opposite side of the pallet fork, and when feeling the collar on the spring. It was very very lose. It almost fell of...

My question is:

Can this collar be pressed smaller?  Or if I do that, can I be sure the balance staff is not ground down to much?

Is this usual practice for an watch maker ?  Or is it better to get en replacement  ? (spring and balance wheel)

 

Again, again  thanks for all help,  ....    :-)

 

Best Regards

 

Armand

How do you know this HS resonates the wheel to the accurate beat.

If the collar fits nice and firm on the staff with just a press of the collar's gap, you may  want to gives it a try.

I have seen collar glued on the staff seventy years ago. Runs too.

If you got suitable tools , the collar can be replaced.

You may find and buy at reasonable price ,such obsolete HS or balance complete off of the owner, through watchparts.org of UK.

If a learner, I would glue the collar on,to read the results on your machine. If acceptable or slow, I will continue to consider shortening HS, collar replace.    And so on.

The Aeromaster is a cool Watch I have one of those too stored in the corner of my dark abyss.
The HS looks like the original one so I can't see why that would not resonate correctly.
But sometimes when serviced one use the HS collet slot to adjust the impulse stone to the correct position. When doing this one might widen the slot or gap a little bit and the end result is what you seen in your Watch, the impulse pin moves to a erratic position.
Gently tightening the collar will solve this problem but be carefull when doing this so you don't mess up the HS.
Gluing  anything into Place in a watch is not anything I recommend to do. In this case you might want to adjust the collar position a bit and that will be impossible if glued into place.

Oh no  removability with ease and reducing risk of damagd, is a good part of the idea with glue.

I use a type of glue that will disolve in solutions friendly to HS. That way the risk of physical damage to HS is reduced. 

If Arko can " tighten the collar ... But be careful   not to mess up the HS"    Lets all listen to his watch ticking.

And the story in going further on....  I need an new escapement wheel to this same watch, when CouseinsUK say

Balance Roller, Pin Lever, Ordinary (799), BFG 582

Is that the same as escapement wheel???

      Epilame / Fixodrop

      By Neverenoughwatches · Posted

      Might that be the viscous nature of oil resisting gravity H  ,  we have been comparing water and hydrophobic surfaces which are similar in principle but water is much less viscous than oil. I guess what we trying to discover is if epilame also has an adhesive trait as well as being oleophobic.

      But it also makes it seem less susceptible to gravity. If you place a droplet of oil on an epilame-treated surface the droplet of oil will still stay in place even if you then flip the surface from a horizontal to a vertical position. That is, the oil droplet remains anchored, and that's the purpose of epilame. If it was just a matter of creating an oleophobic surface we could probably use other, less expensive, methods!? I don't know @Waggy but my gut feeling tells me you're spot on (pun intended!). I believe the oleophobic property is a side effect of epilame which is designed to keep the oil anchored.

      I'm going to be setting up a decent little workshop here at home.

      Saturday morning 27/4 Sunday evening 28/4 Monday evening 29/4 Floor has a drain in the middle so I am hoping that there is very little fall on it, if any. Room is about 2.5 x 2.5 metres square. Can only use about 1/2 of one wall on the right of the pictures which has a sliding glass door in it. And only about 3/4 of the wall to the left of the pictures as it has the door to the house in it. Progress. 🙂

      This makes much more sense now, the oil is withdrawing itself to make as little contact with the epilame as possible. Same principle as wax on a car creates a hyrophobic surface that makes the cohesive properties of water molecules pull together.  The water beads run off only when under the influence of gravity but still remain cohesively beaded up. And as mentioned earlier a pivot would keep the oil in place on a cap jewel.  Epilame on an escapement would be a different scenario, there is nothing to hold the oil in position if gravity tugs at the bead to move, plus the escape teeth pull the oil about Maybe this is why its suggested to run the watch for a short while to remove the epilame to make two oleophobic surfaces either side of the oil, creating a ring of fire 🔥 around it 😅 The oil is repelled by every surface of the epilame even that which it sits upon. So the oil pulls together to make as little contact with it as possible, but the oil cant float above that area, it can only sit there on top of it. Under gravity the oil could potentially run away as an oil bead, unless the epilame has an adhesive property which i dont think it does ? So something else keeps it in position ie a pivot under a cap jewel . But that isn't the case in a pallet jewel situation.

      Balance wheelwheel crooked

      As with every skill it watchmaking, it takes practice. Notice at the top of the document it says, "Practical work - 40 hours".  I can get the balance wheels 'close enough' to flat, but never seem to get them perfect. Same with gear wheels. Guess I need more practice.
