Afternoon on the 409


Recommended Posts

I spent the afternoon yesterday working on the grade 409 Elgin. I disassembled it, washed all the parts and began reassembly. It's good that I have two of these movements because (as always) I lost a few screws along the way. This is a photo of one of the kind of screws that I lost. It is sitting on the graduated surface of a 6" Starrett rule. The thick lines represent the marks on the rule and they are 0.0156" apart (or 0.39mm for the rest of you - I don't have a metric rule, I have a metric dial caliper). The point is that the screw is really (really) small. It looks like a piece of black pepper.

Explain to me how/why my stainless/non-magnetic tweezers seem to be magnetically attracted to these screws?

By the way, two of these hold the upper balance jewel setting into the balance cock.
