This is my first forum post so please bear with me. I hope I have this question in the right area.
I have been pen turning for a while now and lately been having a problem with some of my pen blanks. The problem I am having is I mark center on the blanks drill the blank out from center and look at the other end its no where near center. I will sometimes have a major differnence from one side to another. I use a center finder to help mark center. My table is level and I have checked for square between the bit and table. I did check to see if the blanks I am getting are square and some of them are not square but I didnt think this would make such a differance between ends.
Is there anything I am overlooking? In theory if the bit is going down straight at one end of the blank at center it should come out the same spot at the other end :P. Or so i thought…..Also I am using a blank vise for pen blanks mounted to the press table.
So if anyone has any ideas of what I am talking about or solutions many thanks.
