In the humour to buy another chuck and I was considering a Vicmarc. I have a PM 3520B that it will be used on.
I have discovered that Vicmarc cannot be locked on the spindle via a setscrew like my Oneway Stronghold. That would make me worry about spinning it in reverse for sanding, etc.
Have you found a solution for that?
Perhaps I should stick with Oneway since I am down that path already??
