I just purchased a Van Norman 22LU and it is time for the silly questions to begin.
For starters, I have no idea how to change the collet.
It has a 1/2 inch 50v Hardings sitting in it with an end mill attached.
From internet pictures, it looks like the back is threaded, but i have no idea how to get a hold on it to even attemp to spin it out. I do not see any set screws either...
