Guys, tnx for the interest. Some A's fr yr Q's:
This is for a possible assist in raising the main. I'd gotten a new
one, and it's a fair bit heavier as a result of heavier cloth, full
battens, metal slides, etc.
WRT how much torque I need for this, I wish I had a solid number. The
sail itself is maybe 60-70 lbs before applying the winch gearing. My
guess is that it's maybe 20 pounds (friction included) on a 12"
handle, so 240 in-lbs? (Sail is off the boat at the moment, so it's
guesswork right now.) I'll try it with a corded drill as a test when
the cranker adapter arrives.
The winch is cabin-top under a dodger, so handle swing is somewhat
restricted. I can relocate that a few inches, but wd prefer not to.
News (to me anyway): I stumbled across Sears Craftsman Pro series,
and I see a new(ish?) 20V drill with about a 500 in-lbs torque spec.
At $80 for the drill and $40 for the battery/charger, this looks like
good news for me. It reviews (YMMV) as a good bit superior to the
19.2V one it seems to replace, which has gone on sale.
