The article doesn't give much detail - but it sounds like he got a
massive kickback (not surprising at the rpm involved), presumably from
a the kerf pinching up, or twisting the blade in the job. Presumably a
9" grinder.

How on earth was he positioned though for the blade to strike his
neck? Maybe he was attempting to use it in a vertical chopping motion
through a horizontal log, with the rotating blade in-line with his
bodyline (and the blade (disc!) guard removed).

Nothing to stop the kerf gabbing the blade (i.e a riving knife), poor
ergonomics to control the force of the kickback (because it's a
grinder), no kickback protection (as on a chainsaw) - and bad luck to
sustain a fatal injury, rather than a very scary warning.

Assuming a 9" grinder, it was prolly a 184mm dia blade - very popular & easy
to find size. Can't be arsed to work out the edge speed at 6000 rpm - but I
would scare me!

Instruction manuals are full of OTT safety advice, but it would take a very
brave - or stupid man to fit a saw blade to an angle grinder.

QVC were recently selling an accessory for angle grinders. It let you
cut and sculpt wood. It was a circular blade with a chain saw chain
wrapped around it.

The one's I've seen are designed for *small* grinders, have a suitable
tooth spacing for the rotational speed, *limiters in front of each
tooth*, proper blade guards etc

There are two sorts. The Arbortech (rigid disk) is a lot more
controllable than the chainsaw chain (Lancelot) form, particularly for
avoiding kickbacks, probably because it has better cut limiters. I
wouldn't allow the chainsaw chain sort in the workshop. I even know
chainsaw carvers who won't use them, preferring the Arbortech.

One of the most dangerous similar things to do is some amateur
chainsaw carving, without using a chainsaw that has been set up for
carving. If you do this with a top-handle saw, it really doesn't bear
thinking about.

That will be circular saw blades banned from DIY use next tuesday

Nah - all H&S legislation is only as a result of presumed incidents,
never real ones.


I sympathise with the guy and his family (really) but where was
'common sense' in all this? Neither schools nor parents seem to play
any part in inculcating any thought by their charges. H&S people
positively discourage any 'messing about' with which people develop
sense and thought - we're all being led to becoming zombies, it would
seem.

Only this evening the local rag was hailing a few schools in the area
which have become "Academies" (I thought they were supposed to be
independent of the local authority, but it seems not), and only
highlighted their dance studios and hair salons (oh - and computer
suites - wow!) - never mind woodwork and metalwork shops, maths or
science classrooms. In fact a friend of mine who retired from
teaching a year or so ago assures me that science teaching at
secondary level is now a dead duck. Ho hum.

I was somewhat bemused watching University Challenge this evening when
Paxman read out a good clear description of what a carburettor does, and
asked what was the name of this part of an engine. None of the students
knew; the second answer happened to be right but was clearly mostly
guesswork.

I'm only 28 but I already fear for the youth of today.

I thought that when I saw it. OTOH, how many modern engines have
carburettors? The answer 'injector' was given...

But the first answer "injector" was probably correct for the
equivalent function in the chap's own car.

Just because you're paranoid doesn't mean they're not out to get you.

I've been avoiding this thread - misread as Angle grinder care!
