i picked this tool off ebay last week and it arrived today. i have watched a few vids on youtube in regard to its use. however, i feel like there is a missing link somewhere. the shaft in the actual tool on the top right only has pointy ends. it seems like it would be really difficult to install a male ended pivot into that male ended shaft? the random wheel laying on top of the velvet case in the smallest one i have from the strike train in a pendule de paris movement. even that one seems too big to fit into this tool? oddly, all of the holes in the pivot sizer on the top left in the pic are too big for these pivots. i have the technology to cut the tool and weld in a plug to make it longer. i also have a lathe to make a different shaft with female ends for the top right side. why would anyone need pointed ends to begin with? what exactly do i need to make this work correctly? this seems more confusing than it needs to be.
