    I do not have a twisted bed, but other than coolant drainage it matters not on the other planes mentioned. As you probably know a "shift" pot of them were installed on Navy ships. Monarch 10ee was their choice, heavy and the best and most precise made.
    Kinda hard to level a ship.

    Dusty, put your level front to back on the lathe both in front of the headstock and at the far right. If they read different, you will have twist.
