some are metric, some are U.S. standard. U.S. Standard can be 4-40 or 6-32. Not sure the sizes in metric.

for metric sizes, its not unusual for shafts to be 4mm diameter

Try building your stuffing tube similar to these suggestions...

You can vary the shaft size, tube size, and even substitute some real bearins or oilite bushings if they are available.
