I am sure there was a YBW product test of these in either PBO or Yachting Monthly, but can't find it.

Are they any good, I would need to cut through a 15 mm shackle, bobbing about on the top of a mooring buoy?

£7 for an article?! Ridiculous.... from memory - their budget best buy was the one from either Toolstation or Screwfix...?? Get yourself a free trial of Readly and read the magazine online there? https://gb.readly.com/accounts/sign_up

Thanks very much indeed, but their Buy Articles site must be broken as it cannot pick up any search option I put in on this subject. Hey Ho.
But thanks
 
Ofcourse it would cut it ...Put a 1mm wide disc in be very easy but be careful
it Could also have your finger off!
You could also use a normal grinder with an inverter off ships battery OMG be even more careful!

They tested four, all cut through 6 mm 1x19 cable something like 20 times without drawing sweat. I was somewhat taken aback by the cost of them, mostly well over £200. Recommendation was to buy the cheapest one as all performed equally well in the test.
 
If you have an 18volt drill or other cordless, get an angle grinder of same make, you can then buy a bare unit (no batteries) substantially cheaper and share the battery
 
If you download the Readly app as publicised in the forum today then you can sign up for a free trial and read the October edition of PBO for nothing. It works, I have just done it!

Yes, some of them are excellent.
I used my Makita one to do exactly what you suggest.
Be very careful though - I chose a flat calm day, but a passing boat caused enough wash to create major problems and I could easily have done permanent damage to myself. I'd wear abrasion resistant gloves if I ever did it again.

This is the recommended Screwfix one ... http://www.screwfix.com/p/erbauer-eri662grd-18v-li-ion-4-cordless-angle-grinder-bare/5037j

It comes without the rechargeable batteries which you can't buy separately. Fortunately I was also in the market for a compact drill to keep on board so I bought this which has two interchangeable batteries ... http://www.screwfix.com/p/erbauer-erb679ddh-18v-2-0ah-li-ion-cordless-drill-driver/7611k

So £140 for both tools including batteries.
 
It will all depend on what kind of access you have to the shackle. If you could get the buoy up on deck, or maybe lashed tightly alongside if it is a big one, then a hacksaw with a decent blade will get through it in a few minutes, in greater safety and with fewer flying shards of hot metal to melt their way into your gelcoat and then forever weep rust.

Having said all that, I've got a Makita cordless grinder and it is brilliant. But I already had some other Makita gear so it meant buying a bare cordless unit for c.£80 vs a decent quality corded one for about £50.

Surely you can cut through a 13mm shackle with a good HSS blade in a hacksaw and save yourself ££££s?.

Even bigger mild steel shackles are no bother; I cut through mooring ' destroyer chain ' with hacksaws , using a mole grip or two to hold the stuff steady on top of a buoy, if out on the moorings - otherwise ashore it's the club vice or a workmate.
 
Hi
I use a cordless Makita most days in my work. They are great. Trick is not to overexert the motor. There is a little red light that for best battery life should NEVER come on until the battery needs recharging. Go gently and it will cut 20mm rebar, scaffold tubes and just about anything else. Definately wear goggles as damp cutting discs can fly apart. I would say that gloves are a good idea at least until you get a good level of skill in handling the tool. Always check the disc you are about to use. If it is badly frayed, use another. Eyeballs are difficult to replace.

Only problem with Screwfix is that once out of 12 months warranty, they don't want to know about spares and customer service for many Erbauer products which I think is their own brand. I won't buy any again.
 
Apart from echoing Malabarista's statement about wearing safety goggles (I remember taking my dad to the hospital with grinding wheel bits in his eyes...) I'd like to register my total despair about the fact these cordless grinders are only now being made available.

About a year or two after wheel clamping was made illegal... These grinders would have made wheel clamping a faint threat to illegitimate parking.
 
' Illegitimate parking clamping practices ' surely ?

Those people need the grinder taken to them directly !

Good point about goggles though - essential for this sort of thing, and no excuse not to have them as they're sold for buttons at places like Homebase, anywhere selling power tools; and if one wears glasses they make a good substitute ' ski mask ' if sailing into spray / rain.
