Copyright will exist in the 'industrial' design of the Jacobs Hobber.
A redrawing will not infringe the drawing copyright but it will infringe the copyright in the mechanical design (which is different from aesthetic 'design rights' which apply to non-functional aspects of a design).

Neil, that would count as "unregistered design rights" I think (assuming that the design was not registered) which expire after 15 years.
