Battery Drill to operate winches

I posted this last February so I thought I would follow up with an update.

"I took note of the links and picked up what pvc posted above the Milwaukee (I think the 28V version) is twice the torque of the most powerful competitor.

It certainly looks a good bit of kit.

A number of American sailors use them all the time from comments I have read on Sailnet.

As charter quality sails are often heavier than normal, I was tempted to order an electric halyard winch for the 43DS but didn't as I was not sure charters would use it with care (I once had the main batten cars pulled out of the mast where a Bonzo tried hoisting the main with it still reefed).

Having once had to unexpectedly sailed back from Spain singlehanded on a 38 the idea of a portable drill that enables the winches to become effectively electric ones is attractive. "

Update,

Bought the 28V Milwaukee right angled drill and the "cranker" winch bit that others recommended and they make life a doddle.

On recent trip to France, leave wife in bed , get the boat out under engine, set the boat into the wind on autopilot and hoist the relatively big and heavy mainsail on the 43 using the drill. Goes up quickly and I can then get on with the sailing. If you are short handed can't recommend them enough but it is lazy sailing - but I like it!!

I did need to additionally buy an USA converter transformer from Maplins to recharge the battery. The Milwaukee drill is not available in UK so you have to order it on the internet from the USA.

Milwaukee are one of the top quality power tools, in the same league as Fein, Metabo, Perles etc. Atlas Copco and Milwaukee tools are one and the same thing. There's a fair few on ebay.

I'm going to be absolutely daft now ...

Wouldn't a portable electric wheel nut job do it ? Torque and power to undo wheel nuts ... and at 12v ...

Ok Ok ... I'll go back to sleep !!

Is it impact ? I don't know ... I just saw a web vid for one and it seemed to do the job ...

I suppose it must do impact to "break the hold" for nut to start turning ...

Like I said - was only a daft idea !

None of those except it does have the 28V battery!

I looked into it and only limited range of models are imported officially into the Uk.

DeWalt make a right angle drill but their top one is only 300lbins of torque. The one I bought was the Milwaukee 28V Cordless Lithium Ion Right Angle Drill Product No 0721-21 (Torque 600lbins).

For a larger sail you need a right angle drill with the aditional handle to be able to hold it still while apply the torque - ever had a drill snag when drilling through a steel sheet and it twist out of your hand?

Just looked up a website in USA Tools Plus.

The Milwaukee had lots of torque and stops when luff is under sufficient tensionits

I\'m a little concerned about this....

...What do you jam the handle of the drill up against? For surely it will be trying to go back in the opposite direction to the winch and if you're relying upon manual means to counteract this, aren't you going to use just as much effort as you would in grinding the winch yourself in the first place?

The drill has a reverse direction switch so you can use the winch at fast speed at first and slow speed but high torque at the end.

You dont need to jam the drill against anything just hold it with both hands (similar to an angle grinder) and let the drill do the work. In fact the only work is pulling the drill trigger with your fore-finger!

So how good would it be at turning the starter handle on the front of

a diesel then?

I'll have to wait a couple of weeks for your answer as I'm off to Greece at 5am

I supose it depends if you have a compression lifter.

The drill certainly "stalls" once the luff is too tight so it produces enough torque to lift a wet 43' main and overtighten the luff. I was concerned that it might have enough power to rip the sail but thankfully not.

In the blurb it said ideal for drilling large diameter holes in timber beams (floor joists).

Members of this Forum pointed me to it in the original thread on this subject last February (use search Facility).

AFAIKR its was called the cranker. I ordered it separately from the USA.

Get a piece of 17 mm square bar and turn one end diwn in a lathe to about 12 mm dia to fit in the drill chuck and bobs your etc

One I saw advertised in the states was as you describe but the one I bought had all 8 splines as per the normal winch handle.

Yes, they are started with one of these....

Which, as you can see has a substantial reaction "wand" which is hooked under the rear wing mounting (on a McLaren anyway)

Also, it is NOT the same situation as an angle grinder as someone else has said. Not unless you try locking the angle grinder spindle into the top of the winch that is, which would not be a good idea at all.

Spinning the unloaded winch with the drill would be no problem but then even the most crippled arthritis or angina victim wouldn't have a problem with that. It is when you want to put some real load onto the sheet that the basic laws of physics come into play and controlling the reaction of the drill handle will be the major factor.

I can only add I use the drill and it is no problem to hold it as the Torque delivered is easily held in your hand due to the mechanical advantage. The drill head to handle is about 15" and there is a second handle at rt angles but it is not too heavy or awkward.

Demonstrations will be available on the Scuttlebutt Cherbourg cruise if people give me enough Alcohol!!

Give me a long enough lever and I will move the world!!

Of course another law of physics is that mechanical work done = force X distance moved. In other words exerting a force without producing movement does no actual work. So statically resisting a force does indeed require significantly less energy than exerting that force over a distance.
