Why not use a winch with only 1 circlular plate on the axle? Once the
projectile is re-loaded turn the winch through 90 degree's so that the axle
is in line with the dart. Fire the dart and the thread will spool off the
end of the axle automatically, you will of course have to be careful how you
wind the thread onto the axle in the first place so it doesn't get tangled.
