who ever designed the movement spacers for the 8ae&ac, never thought of parts being rare

TODAY WAS BAD i broke a staff on an 8ae today putting on the spacer...i hate these things..they never go back on..always a pain in the a@#.. i saw my watchmaker do once before, now i did it...i mean this has to be a bad design..does anyone agree that these were a bad idea...thats why i think you see alot of the missing because people didn't want to risk breaking a staff like i did...good thing i had a spare balance complete..i guess the next major buy i make will be a staking set and a good roller jewel remover....or a lathe, sorry for the rant but i had to relieve some stress from breaking a staff...
