Hello again Chris. Forgive me if you all ready know about this but I've a Sherline lathe tip I'd like to pass on.
Get a couple or three of the 1/4" Two Position Tool Post (part no. 3003) and load each side up with cutters and centre them. When you need to change to a different tool, simply swap the tool posts. It takes seconds and doesn't interrupt the work-flow.
At around £16 per post, it's a lot cheaper than a quick change system.
They also make tool posts for 3/8" if you need to do something a bit beefy.
Steve
