Hey David...

check with MSC industrial supply or Grainger  for shaft couplings    ( used 
to join 2 shafts say from a motor to a pump)
they are normally standard shaft size inside diameters and have set screw 
securing...  by using half of one and the disc, you have a wonderful set up 
for rotory disc gap....

if all else fails    email me and I can probably turn one down on the lathe....
