All of the "worm gear" winches I've seen were not true worm gear, worm 
gear wheel, which have very little friction, but a tremendous gear ratio.

All the winches had a worm gear, but in place of the worm gear wheel, 
they had a pair of stamped spur gears stuck together with the teeth 
offset enough that the angle allowed the worm gear to kinda fit/mesh in 
the angled slot.

These have a lot of friction because the gear mesh is not a good one in 
addition to the gear ratio.  OTOH  the appropriate worm gear wheel would 
likely cost more than the whole winch and most importantly, they work 
and are inexpensive!
