Avoid Small Parts Flying


danizzz

Recommended Posts

I'm working in replacing a spring in the balance incablock, the spring that holds in place the jewel on the balance.

The last time I tried the spring literally flew away.

Is there a technique or a protector to avoid small parts fly away forever?

The bag/clingfilm tectonics work BUT I find them a hindrance when working with them. Once bitten twice shy I always, always when loosening a click spring to remove a jewel I steady with a piece of sharp peg wood so when it is released it does not spring & fly.

The best way of fitting is to modify & shape a sharp piece of peg wood to once again to hold steady whilst fitting.

So did I. I've lost a spring of the Incabloc while trying to put it back to the cap.

Later I found that it'd better to use No2 tweezer instead of No5. By the way, the price of the springs are not comfortable, 3$ for the lower and 6$ for upper (ofrei).

I forgot to mention on my recent reply to this post is I have found (through many mishaps & many attempts) is to make sure everything is spotlessly clean, tweezers,pin, peg wood etc.

BUT also make sure that the spring is not magnetised. They are supplied in plastic pouches & although plastic keeps items nice & clean it is notorious for creating static. These springs are incredibly sensitive the least bit of grease or static & it is just an impossible task to fit.

Another help for the really small springs is a microscope. 

 

If the spring flew when just re-locating a jewel then the spring was either not seated correctly or damaged.

If it is incabloc should not fly. Incabloc has a hinge that prevents falling out. If is Seiko antichoc system or similar you can manipulate its spring without lifting the twizers from it as you can see in this video I made.

I use much the same method, with resetting the spring once you get 2 legs set you pretty well have it under control if you work gently, that said I was working on a Seiko clone yesterday and it was a different fish all together, either the spring is too small or the groove is too deep but even with 2 legs in it was still not secure, talk about a pain.Don't think I have ever spent so much time getting one installed.

A set of good tweezers is a must when handling delicate parts..eg hairsprings, inca-springs..

 

You can try all the tricks above (and do help..!) but if you're tweezers are still not up to the mark you will still have problems.

 

After hitting the 'buy' button on that high end tweezer you may feel some regret/doubt but once you try them the difference is like night and day.

Well, I found the wayward Novodiac spring for a second time; it was hiding in my glasses case. I used an extendable magnet that I bought to get small metal things out of piano actions but it works for watch parts too.

You are right about good tools. I always got the better tools for working on pianos; yes, more expensive, but it makes all the difference and ends a lot of frustration.

Wise advice.

    • I have read some suggestions that it can cause wear , particularly on the fork horns of a fully treated pallet fork. I've had half a kilo of steriac acid powder on a shelf for almost a year now, might have a little play today with a heater and a jar.  I think its because it gets into their cleaning solutions Mike. Theirs or anyone else's that services the watch next time, or if they need to strip back and rebuild. Could preclean but thats all time for a pro.
    • As I'm only cleaning watches in small numbers at home, I pre-clean any significant deposits of old grease and oil before using the cleaning solutions. I scrape off deposits with pegwood and Rodico, and if really dirty, wash parts in naphtha with a brush.  So I'm happy using DX, but can understand why it's avoided by the pros.
    • I think attaching a nut to the lid to pull it off is the least destructive, any damage damage on the outside is going to an easier fix than any created when trying to push it out from the inside. Scratching up the inside of the lid , mainspring or arbor bearing will be risk. Just my opinion.
    • yes the things we read in the universe I did see some where it was either difficult to clean off or it contaminated the cleaning fluid there was some issue with cleaning. I was trying to remember something about grease where as opposed to a substance of a specific consistency they were suggesting it had a base oil with something to thicken it. That conceivably could indicate that the two could separate and that would be an issue. But there is something else going on here that I had remembered so I have a link below and the description of the 9501 notice the word that I highlighted? Notice that word appears quite a bit on this particular page like 9415 has that property all so they 8200 mainspring grease and that definitely has to be mixed up when you go to use it because it definitely separates. just in case you didn't remember that nifty word there is a Wikipedia entry. https://en.wikipedia.org/wiki/Thixotropy   https://www.moebius-lubricants.ch/en/products/greases I wonder if what you're seeing is the boron nitride left behind after cleaning. In other words it's the high-pressure part of the grease and it's probably embedding itself into the metal which is why it doesn't clean off and shouldn't be a problem?
    • Yes and no. I use Moebius 9501 synthetic grease and it is significantly runnier than the Moebius 9504 synthetic grease (and I assume Molykote DX) that I previously used. I haven't seen 9504 spread and it is in my opinion the best grease money can buy. However, my current method of cleaning doesn't remove it from the parts, so that's why I have decided to use the 9501 instead. I believe I read somewhere that Molykote DX too is difficult to clean off. Thinking about it, I'm pretty sure my 9501 grease which expired in June 2022 is runnier now than it was when it was new, but whether new or old it always needs to be stirred before use. So, that's why I treat the parts of the keyless works, cannon pinion, etc. with epilame. That was very thoughtful of you and something that had completely passed me by. Not sure what the epilame will do when it wears off in a non-oiled hole. Anyone?
