Here is my problem.. The tip of my live center is being eaten away.
The diameter of it is being reduced to a little bit of nothing. Back about 1/16 or a little more. Should the taper of the live center, and the taper of the mandrel both be 60 degrees?
From an earlier post, I read where the pilot hole in the end of the mandrel might not be drilled deep enough...and that might be my case.
It is real close for depth. I will check more on it tomorrow.
I don't put any more pressure on the mandrel than i feel is necessary, usually just sliding the tailstock up to it and then just touching up the pressure just a very little.
If I have to replace the live center, then tell me what is the difference between the cupped center and a regular center...and which one is better and why?
This really has me puzzled.
Thanks
Harry
