    The trigger lock button is a right nuisance for lefties such as myself. Right hand users need to reach around to it with the finger tip whereas a lefty pushes the button in every time with the base of the finger unless we can consciously and deliberately avoid it. I've been known to have a trigger locked drill in hand when the bit binds up. Not fun when it's a good sized drill. Let go, duck and pull the plug or risk broken bones. Similar problems exist with most power tools but we southpaw are a cunning type.

    While I must agree that operator misuse is the largest reason behind angle grinder accidents, there are scenarios where mechanical failure can also create the scene for an accident.
    I have an old 9" Hitachi angle grinder, a beast of a thing that weighs about 10kgs, is about 2HP, and which will just about throw you off your feet on startup, if you aren't prepared for the initial torque reaction of the motor springing into life.

    It's been reconditioned at least twice, and despite not long ago having a new switch fitted - when I was grinding on Wednesday afternoon (in a difficult, "cutting off heavy lugs under a truck turntable" job), I was stunned to find that when I released the switch trigger, the grinder continued to run on, with the switch having failed, and jammed in the "on" position.

    It was disconcerting, to say the least - and downright dangerous if it had happened right when the disc had jammed, and I wanted a quick shutoff.
    I have a feeling this particular switch mechanism is prone to failure, and I'll be interested to find exactly what has gone wrong with the mechanism, when I dismantle it.

    I have the same level of attention to all angle grinders, as I do to coming across big snakes in the wild. I treat them with extreme respect, and know full well they will kill me, first chance they get.

    One of the things I find is, as I'm getting older, I've decided to never start on any serious angle grinding jobs, from mid-afternoon onwards.

    I find my attention level tends to drop from mid-afternoon onwards - and when faced with a need for serious angle grinder use, I find it's better to approach the job in the early morning when you're still fresh, and ready to give these dangerous beasts, the full attention to grip and job approach, that they demand.

    hey mate your game, i,m only new here but, for myself i have a general rule with big grinders, #1. don,t lift it over my head, #2, don,t stick big grinders into confined places.
    i know it sound of me being to criticize, but would hate to here of another big grinder accident.
    can you use the gas axe on it?

    Thanks Mick, the job was a couple of years ago, and I "got 'er done" without any major drama. The turntable (5th wheel to our U.S. friends) wasn't mounted on a truck it, was mounted on the end of a couple of lengths of huge channel iron (around 3M long), and the channel iron was used as forklift tyne extensions. I'm guessing they were using the setup to move semi-trailers around with a big forklift.

    I bought the setup at an auction, and I had no need for the arrangement, so I cut off the turntable and sold it, and used the steel channels on another fabrication project.
    I didn't have a gas-axe available at the time, but I've made sure it's available at all times now, as an option. Then when I get the gas-axe out, all I have to worry about, is setting myself alight!

    I started in heavy equipment at 16 and I've got to 71 without killing myself with powered machines, so I must be reasonably careful - or else I'm just lucky!
    I've gashed a couple of fingers a couple of times with angle grinders, without long-term damage - and you wouldn't believe it, both times it was with small 100mm (4") and 125mm (5") grinders!

    ha,ha , yes, i get that.

    yeah, thanks, i get all that, we do what we can with what we have, been there to many times.

    i hope you didn,t mind me pointing it out, i didn,t know the circumstances, i guess its a habit to point out safety stuff that was drummed into me and seeing/hearing of accidents.

    funny you should say, ive never had a 9" accident, but the smaller ones have given me a couple of nicks over the years.

    In this day and age, oxy for cutting the small stuff say up to 5/8" is old technology compared to a modern single phase plasma cutter. Fantastic for gouging as well. A few days ago I was replacing the ball joints on a 6S blade. A decent generator, air compressor and it blew the metal away quick as you like, and now we have auto darkening helmets that also go down to the low shades, visibility is great. Need a bit deeper here. Zap and it is done.

    Of course the small single phase stuff will not do big jobs very efficiently, but I struggle to think the last time I fired up the oxy just for cutting steel.
    Gold, the colour of choice for the discerning person.

    Agree. Got to be well over 25mm thick before the plasma cutter has problems.

    And now we can actually get oxy & acetylene from Bunnings without having to part with a kidney to the big gas suppliers for bottle rental too.

    I don't know anything about ankle-grinders causing death, you'd have to be doing something very wrong although I have killed a few of them in my time. Now heart attack when using a wet saw?
    I actually find them safe to use although switching on the later made Euro tools are a bit silly and the hands of a Gorilla are necessary to use some of the Fein grinders.

    It would be a glorious death.
