[QUOTE="marcochezzi, post: 958412, member: 21001"] Flipped again in the collet housing and a 2nd 2,9mm hole drilled through the centre of the shaft, 9,6mm from the first.. [IMG]https://i.imgur.com/pAd3hfE.jpg[/IMG] finishing the ordeal by silver soldering two correctly sized pins through the 2 holes... Silver soldering leaves a hard flux behind, much like brazing, and you need to polish the part on a spinning wirebrush wheel... The part is way way too small for me to push onto a spinning brush by hand without risk of damage to the part and lost fingers, so I scraped where I could, but this is how she will stay until I find a small polishing brush for my dremel tool, then will try again...
