OK - finally got some time in the shop and (almost) finished off the drawbars. I decided to reduce the length of the hex. I also had to remove the bearing, as the second one that I purchased had a 13mm bore, where the first had a 12mm bore! So now, only the 12mm race is incorporated into the drawbar and the 13mm race and 13mm bearing are in the quill.
Here they are next to the ones I have been using:
Note the spacer needed to fit between the top of the quill and the pulley bearing housing. This is incorporated into the new drawbar.
Close up (blue is 1/2-13 and red is M12x1.75):
All that is left to do is drive in the ø4mm roll pins and they are ready to put into use
