Thanks - I considered that too but on this drill its tight with the main shaft (spins with the chuck).. I tried looking up similar drills and haven't found any with a similar fixture
I apologize if this isn't considered vintage - couldn't really find any other info on it. I don't know much about it other than it was used very little - it was given to me for some work I did. What is the knurled piece by the chuck used for? I couldn't tell if it was for assembly of some other...
