Having purchased so many manufacturers chucks over the years I find dedicated chucks quite t5he go for me. My pen jaws are permanently fitted to my dedicated VicMarc chuck that also has a fixed 1 inch ten thread entry. So I used to have and have reduced the number of lathes and chucks accordingly. To me changing jaws was always a pain in the bum,the screws holding to me are not really up to scratch in closeness of thread or real alignment.
So the bottom line for me has been hit and miss for reasons stated above and my determination in the end to use dedicated ,beaut fitting chucks. Guess it comes down to real use and how long you keep and use things. Your choice.
