ExoticBlanks Precision Machine Pen Center

Has anyone used one of these :

If so, could you please tell me the cone angle between the sides.

I am looking for a MT2 live center with a cone angle quite a bit smaller that 60 degrees.

I do not use a mandrel so the hole down the center is not important to me.

Hi Mal,

My geometry is not what it once was, but with a little calculation, I believe it closely approximates a 30 degree angle, each side is 15 degrees off the centerline.

Hope that helps.

Dimensions: In a length of 1.25", the diameter changes from .98" to .35". Please let me know if my calculated angle is completely incorrect!!

Thank you, Ed.

Right nice of you to resuscitate your trigonometry cells for me like that !!

I think I will add one to my order.
