Hi Paul,

I am using a 12mm diameter main shaft and have drilled holes through this. This way, as I screw the coil cores together they tighten and grip the shaft.

I think by doing it this way I can keep the centre of the core solid and not have it interupted by drilling a hole though it. Not sure if it makes a difference as far as the magnetic flux goes but you never know.
