Have seen a old reel (Penn senator 12/0, from memory), and a cordless drill with a U shaped thing in it. The 2 fingers of the U grab either side of reel handle and winds in. No mods to reel needed....

Now you need a shimano beastmaster 9000, to 'assist' in reeling it back in...... :)

(I do have one, but only used on 200m + drops - not for surf casting...)
