Just had a couple of halyards unreeve from a 28ft mast-yes, my fault! Anyone recommend easiest method of re-threading them, please? (Mast is in the garden now)
then go to the the mast head with an electricians' 'mouse', or length of old riggiing wire, and thread that over the sheeve, and down through the mast. Tail on the halyard, and pull it through from deck level.

I've recovered this situation with a mouse consisting of a galvanised shackle pin tied to length of whipping twine, dropped down the mast. The mast does not need to be vertical, only inclined enough to persuade the pin down. It can be eased around obstructions either by rotating the mast, or by drawing it past with a magnet on the outside. The maget will also help draw the mouse to the correct exit hole, or you can insert a loop of fine wire at the exit hole to catch the mouse as it comes down.
If there are remaining halyards or loose wires still reeved, then these may obstruct a mouse. A better method then is to use one halyard (or wire) to draw a light line up the mast, then attach the two dropped halyards to the line and draw all three back down. This method is a bit fiddly around the masthead blocks (remove first if possible), and at the exit holes, but is otherwise simpler and does not involve inclining the mast.
Situation now recovered! Thanks Neal and Andrew,all good stuff and pointed me in the right direction. I did it with a length of fencing wire, 2.5mm with the mast horizontal, works fine!
