Having had a few parting-off disasters I've been doing some searching around for ideas; now it's time to consult the experts ...
Is it better to run forwards with the tool in the normal position, forwards with the tool inverted in a rear toolpost, reversed with the tool inverted in the front tool post or reversed with the tool in a rear toolpost (all assuming a camlock chuck mount)?
What speed? With power feed or manually? With or without coolant? How should the parting tool be ground? Does it help to use a spring or bungey to take out any play in the cross slide? What are the other secrets (other than squareness and rigidity)?
