I need to fairlead my Main Halyard through the Mast of my Hunter 240 and have been unsuccessful so far. The problem is that I cannot get an electricians tape (snake) through the top of the mast. The Main Halyard roller prevents the tape from bending and moving down the Mast. When I try from the foot of the Mast the same roller prevents the tape from bending and coming out the top. I do not see any way of removing the roller. I'd prefer to not remove the rivets at the mast head if I do not need to. Has anyone successfully rethread their Main Halyard through the Mast and can provide me with instruction?To date I have removed the rollerfurling hook from the Mast and successfully fairlead a messenger throught the Mast down to the foot of the Mast, but am still about 18" short of the top of the Mast. It has been recommended that I use a guitar string to fairlead a messenger from the rollerfurling grommet up the Mast to the head. I will try this tonight.
