Unless you want to see a whole load of pens coming back for new transmissions and customers bad mouthing you for shoddy workmanship, I would suggest leaving the transmissions seated as designed...
These pens are designed to be used in a certain way... playing with shapes is a fine and dandy thing to do, but unless you know the intricacies of the mechanisms we are better off leaving it alone.
I just let the customer know that the pen is meant to be twisted in either direction and that continuing to twist count-clockwise (looking down from the cap) will unscrew to top and allow them to change the refill... I will know also let them now about unscrewing the nib as Eagle suggests...
On pens like the cigar where the top fits the mechanism tightly, I really don't like the idea of the customer pulling the top barrel off... besides they will never get the grain match again..
