Folks, I'm thinking of using subject drill in an unusual application,
turning a sailboat winch to hoist about 40 lbs; occasional use, not a
steady workload - and a right-angle drill.
I've read where the 28-V Milwaukee will do this, but that's an
investment I ain't prepared to make, and I'm looking at Ryobi 18V and
Craftsman 19.2V My concern is torque capacity.
The Ryobi spec says 130 inch-lb minimum, but I haven't seen anything
on the Craftsman. Anyone here have a manual, or spec, or some
experience with this admittedly oddball usage? Thanks, all.
How much torque do you actually need? The Milwaukee is rated for 1081
in-lb, or about 8x as much as the Ryobi. That's a significant
difference. Most of the other name-brand tools (Makita, etc.) max out
at around 600 in-lb or so.
Enough to trim a #1 Genoa sheet in 30 knots of wind when you are up to
your ass in alligators and 4-6 footers are running on 200 ft centers.
This is a classic sailor problem.
The wind is free and sailors expect everything else should be to.
BTDT, don't need the t-shirt.
I'm curious--if you are strong enough to resist the torque of the drill, why
can't you just use a winch handle and do it the old fashioned way? And the
winch handle doesn't get upset about being doused with salt spray.
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.

That boat has a masthead rig with a relatively small mainsail. I think
your real problem is friction, not weight. Personally, I would forget
the electric winch and install a Tides Marine Strong Track system. I
put one on my boat and it now feels as if the sail is not actually
attached to the mast. On your boat, the strong track would mean you
would raise the sail almost completely without using a winch at all.
We aren't exactly young, but my 110 pound wife can fully hoist our
main by hand. The winch is used just for the final tensioning. The
other nice thing about the Strong Track is that when you want to lower
the sail, it drops like a rock.
It's about $25 a foot installed. Worth every penny.
Yep, I have the Strong system installed. (It replaced the world's
oldest Hood Mainfurl.) But 60 lbs is 60lbs.
Awwwww, believe me that I need the winch. Yep, it drops right now;
that's not the problem. But thanks. ~ AS

But that's part of sailing, and keeping sails in trim manually keeps
sailors in trim.
