Note:Since this lathe has an Inch lead screw, do
not use the thread dial when cutting metric threads.
Instead you must leave the half nut engaged until
the threading operation is totally complete.
During threading keep your hand on the
half-nut lever ready to disengage the half
nut to avoid potential carriage/chuck crash.
