Hi Duncan.
I have just completed the bell stand on one the clock I am making.
I decided to fit the pins into the finials rather than the arms of the bell stand and you are right about the angular position of the holes in the finials. I just fitted the finials and tightened them and then set out the holes diagonally opposite each other. I have numbered the finials, square washers and columns to be sure they go back in the right place.
Let me know if I can be of any further help

This is how I rolled the hoops
The bell is not really the correct shape for this clock but it is the best I can find/afford at the moment. If I can find a better one in the future I will remake the bell stand.
I cut the two half round rings in two and soldered them to a central disc where the bell is fixed.
I need to shorten and tidy up the length of the pins
