No cutting the parts apart required. The use of a "paper glue joint" -
glue on both faces to be joined with a piece of newspaper between them,
also with some glue on it, creates a plane at the joint that holds for
turning - but can be opened up by starting with a ultility knife to
begin opening the joint, then using a kitchen knife to open the joint of
completely. Leaves a little paper on each joint face that's easy to
sand off.
