I haven't tried it yet, but I was thinking of a wooden dowel or even some Silver Steel to bend round, hope fully by hand.
I was thinking
if I tubed a pen blank and cut this in half, about an inch long, then got a piece of silver steel slightly smaller.
If I put a watch part across the pen blank, rested the silver steel on it and then used the pillar drill to gently ease it to shape, it should work
