The other day I got tired of the tail stock not locking down tight enough so I tightened the nut on the bottom too tight and the iron part of the tail stock broke on the back side where the tightening handle is. I called Delta and they sent me a new one and I got them to send me a new eccentric shaft too because I thought something was wrong with the one I have since the tail stock won't get tight enough. I put the new one together and it does better but it still will move if I crank the center very hard. Is anyone else having trouble with this or am I just trying to put too much pressure on the center? I am using a Oneway live center on the tail stock and have strarted using the spur center on the head so it will have some bite. I typically use a safety center that has the center pin in it that springs in when pressure is applied. I can't remember the brand name.
Sorry for the long post. I would appreciate any insight you may have.
