    Peter,
    Learned something today, never heard of quad rings or X rings. I've worked with O rings for my whole career. Googled them and and understand the advantage. Wonder why they aren't more popular?

    My experience, you won't hold .002 tolerance consistently. The electrode will be tapered as it is being used, and the guide and electrode needs clearance which will cause some run out. I think you...
