    Got air blast?

    How about a whistle attached to a toolholder?

    Oh how annoying that would be. But also so effective at getting people to run to that machine!

    Impossible to know without seeing the toolholders.

    Chances are you have some tools that are perfectly fine and others that should probably stay out of the new machine.

    IME, the importance of full 4th has more to do with the ability to index in increments finer than 1 degree.

    For the parts we make, we're happy with 1-degree and it's bulletproof.
