Thanks for info

After agonizing over many Spur and Worm gear winch details and even
considering a JET 2000N for $750
( moment of insanity ! ) I decided on the *Fulton  KW3000* and a powerful
half inch drill motor
that turned low revs ( like the 300 RPM of a *Milwaukee Hole Hawg* Drill
Motor )
which I am now eyeballing as I could use a nice drill like that around the
home jobs !

Also since on sale at Grainger right now for $143 - that wasn't too hard to
swallow for something should work fine
and save my arm muscles during occaisional tilt downs !
