Nov 6, 2014   //   by Bob Warfield   //   Blog, Manufacturing, Products, Techniques  //  24 Comments

You know what I’m talking about–those little nibs that are left after parting off.  If you’re lucky, you’ve got a hole down the middle of the part and no nib.  But if the part is solid, there will be a nib.  It’s just the physics of it–the part starts to wobble as the nib gets…
