For those who are interested in putting together their own equipment
(etc.) Harbor Freight makes a hand winch, rated at 2000 pounds, that
has a 40:1 worm drive. If you hooked it up on your draw bench a four
year old could turn the handle for you! The winch has just gone on
sale at HF for $19.99 under number 5798-5VGA, it is normally $30.
