How should a mandrel for a close end fountain pen for Lou's nib holders plastic should look like?
I assume it's a plastic rod threaded at the end that goes into beall chuck.
Right?
Now, since this is not an expanding mandrel it will not fit tightly into all drilled holes. A hole made with the same drill bit has slightly different diameters in different materials. If unthreaded part of the mandrel does not fit tightly into drilled pen body hole then mandrel does not provide much support along the whole length.
Am I missing something here?
