How do I remove shock springs in Smiths Cal 0104

[mikepilk]

Just dismantling my latest acquisition, a 19J Smiths Cal 0104 and notice the shock springs are of a type I haven't encountered before.

I assume they just rotate and lift out ?

You rotate it counter clockwise and the spring will come out on one side through that gap. I'm assuming that it's not fixed onto that metallic bar so on that end you might just be able to lift it.

You almost got it. It is connected to the bar and creates a hinge so it won’t get lost. When you rotate the spring ccw to the gap, it will pop up, rotating on the bar.

Thanks. Sounds like a better design than some (e.g. Seiko) that are only too keen to ping-off never to be seen again!

When parts fly away the problem is with the person that does the job, not the design.
Check my video showing Diashock installation technique using a carved toothpick.

That's the way I did it in the end - not that difficult on the larger ones on the balance. It's the smaller ones on the train that I struggled with.  

It's not good engineering as they are relatively difficult to fit,  compared to the Kif, Incabloc, where you are less likely to lose them.

Maybe that Kif/Incabloc have enough patents to stop similar designs.

Small ones can be safely and cleaned together with the place.

Again, that's your opinion. But with millions (?) of units produced, Diashock is an excellent shock system which poses no problem when handled properly.

I use Jdms method or something similar. I use a piece of hollowed out pegwood and ease it around with pegwood and tip of tweezers. Never had any real issue with diashock

No it's not my opinion - one is a better engineering solution than the other.

You have to admit however, there is nothing like having a part fly away into oblivion, hearing the report of it's vicinity and successfully finding it with the broom. I don't think I have ever been closer to God and Jesus than when I decided to take up collecting and repairing as a hobby. "Thank you God ohh thank you Jesus" LOL...! Can I get an Amen..!?!?

Amen brother! Although I have been known to use different words when the part has disappeared...

I would also like to add, however good or an expert one might be, it is inevitable that very fine parts will at some point go missing or ping away.(to be found or not) It is just the nature of the craft. We can lessen the events with due diligence and preparedness. With time and practice I have noticed a definite decrease of incidences in my own work. I also have a pull out "catch all" that has saved me time and heartbeats on many occasions. If you've never gone wide eyed, open mouthed gasping in horror at the floor, you're doing it wrong! LOL...!

Yes indeed, depending on the piece I'm working on I usually just sob for awhile, curse my existence and then just move on after searching around on the floor for the better part of an hour like some crack fiend. LOL.....

You forgot to add, “while hoping my wife doesn’t come into the room and find me.” ????????

My skills are improving, but I still get careless and the occasional part pings off the table.

My first search is using a powerful torch

Then I uset a strong Neodinium magnet to sweep the area.

Finally, I empty the Dyson, and vacuum the hole desk, me, room and examine the contents.  The time I've wasted ......

Until I perfected the art (and realised a slighly soft surface helps a lot), I had problems with cap jewels - like playiing tiddly winks, and not being magnetic even harder to find.

We all loose parts from time to time. Good tweezers such as Dumont help and when dressing them; leave a slightly rough inner surface near the tip makes a big difference [emoji16]

I've just this minute finished dressing my Dumont #2 with some medium wet and dry !

I removed the shock springs by turning them - I like them

Much easier than Diashock
