... example needed?
The worm hook to extract cartridge remains ...
... already I glued a nice long spiral onto a stick and just then looked into the literature ...
... bloody mental cinema ...
... it is not one long spiral but two short opposite spirals, which makes sense for the purpose.
First soldering trial with the 0,3 mm copper wires went bad until I remembered that there is a protection around
Once removed, results became better, but still quite breakable, but then realised, the spiraling method does not work ...
... okokokokokoko ...
... back to start, rethink and resolder ...

... but how to do the double helix?
Took a fitting drill with the right lead ...

... and carefully embedded the wire into the grooves.

The lead still being too high, respaned the opposite way against a 1 mm mandral, and carefully readjusted the lead.

And here we are, it finally worked ...

... even fits for the bore

That is why I sometimes hate myself, took me days to work this out until it fitted ...
... so I got really time enough to hate myself ...
... deeply contrited ...
...yours dafi
