HOW2 match winch torque with electric drill ?
I would like to try powering my main winches [Barient 28s] by a
[preferably] portable drill/impact wrench/etc., as at least an emergency option. Has anyone successfully done this ? If yes, how'd you determine what you needed ? I see that there are now numerous new portable ones that range up to 24v. If portable ones are insufficient, how 'bout such as DeWalt and Milwaukee 1/2" corded models ? What has been found unsatisfactory about such an application ? Appreciatively, Courtney -- s/v Mutiny Rhodes Bounty II lying Oriental, NC WDB5619 |

It had a 5/8" hex shank on one end and a winch star on the other. I am sure it would require a lot of torque. The demo was being driven with a 24V low speed right angle drill. Similar to a Hole Hawg but battery operated. It was red so I assume it was a Milwaukee. The thing is, electric winches up to the mid 50s use a 3/4 HP motor geared down to about 50 RPM. I don't know of a hand drill that can deliver that much torque so you will have to do the last few turns the old fashioned way.. -- Glenn Ashmore I'm building a 45' cutter in strip/composite.

A unit similar to what you describe is commercially available. I think its
"The Wincher". You can probably find the specs for the motor on the Net or call them. I'm sure they would give you specs like motor HP, torque, current draw, etc., if you make is sound like you might be interested in a purchase (and maybe you are).

I use a very inexpensive 120 vac 1/2" drill motor from Harbor Freight for
going up my mast. It works like a charm. Only trick is coming up with the bit that fits into the winch socket. Simple for any machine shop to make. Tsailor If portable ones are insufficient, how 'bout such as DeWalt and Milwaukee 1/2" corded models ? |
The Milwaukee 3109-24 right angle 18 volt drill delivers 600 inch lbs
of torque at the low side rpm of 350. I use this drill with a winch head bit on the low speed side of my barient 27's to hoist a 500 sf full batten main. Works out to approx 30 rpm at the winch at full speed. Works like a charm. I get 4 hoists to a charge. No drawbacks and I can decouple the tool and use it for other tasks. Buy an extra battery and charge it off your inverter. $350.00 all up.

search winch bit on ebay. they sell them for $20.00

I don't know of a hand drill that can deliver that much torque so you will have to do the last few turns the old fashioned way.. I suspect those winch motors were turning the drum directly. The drill motor would be using the winches gears. A person can exert only about 50 lbs with a one handled winch handle. Maybe a bit more if he grunts and is big. 50 lbs x 10" = 500 in.lbs A Milwaulkee 18V cordless drill spec gives 600 in. lbs of torque. Maybe it is enough. You would probably want a short tether on the end of the drill to clip to the deck and provide a reaction force (otherwise you would still have to provide 50 lbs of force on the end of the drill to stop it spinning!) I do recall the "Wincher" used such a strap but it was $2500 or so! I suspect that this drill is just enough grunt for the job, but I wonder how long the batteries would last tacking up a narrow channel? Perhaps the corded one would be better suited? -- Evan Gatehouse you'll have to rewrite my email address to get to me ceilydh AT 3web dot net (fools the spammers) |

... Marc, What do you do, if anything, regarding the previously referred to [potential] problem of....the drill's reaction force of ~50 lbs ? Evan suggested a tether. Thoughts ? Also, since a much less expensive AC drill can be had with similar capabilities, why did you think the DC unit worth the difference, especially since the batteries must be recharged anyway ? I would definitely consider a length of cable shackled to a pad eye. When my heavy duty drill grabs it is impossible to hold on. It could break your arm. The battery operated drill will be a little more mobile but mainly you don't have a cable carrying 120VAC laying around the cockpit. -- Glenn Ashmore I'm building a 45' cutter in strip/composite.

TSailor,
If you also use the drill with the sails, what's your boat's displacement and how big's your main sail, please ? If you don't use it with the sails, why not ? Is it inadequate to the task ?
