Like when a used 9"disc on my 5" grinder exploded when its circumfrencial speed exceeded its design speed and a quarter of it embeded itself in the palm of my left hand.It hurt a little bit and left a 3" scar
You win Wayne, I can't beat that. My grinder was only a cheap 100mm Ozito but I must admit I did put oversize discs in it. The switch type required it to be slid forward and then a lip dropped into a slot to hold it on. In practice rubbish jams the slider from moving easily and often vibration makes the switch let go. The other problem was that you had to press the rear end of the slide switch to make it turn off. Most other grinders have a spring loaded "deadman" switch which has to held on by one finger. As usual you get what you pay for.

I am interested to learn whether the grinders come with a switch other than the slide variety.If so I'll buy one
The angle grinders that fitters used on our rigs, had spring loaded switches - and some type of brake.
When you released the switch, the grinding disk stopped real fast.
Dunno what make of grinder - but they are out there.

On the mine maintenance shuts I have done, all grinders had to have deadman switches.
I hate them, as when you are working for hours with a grinder it becomes awkward to use having to lock the trigger continuously down.
Even the long tang safety down the handle of the 5" and 7" are bad with gloves on.
They all really need the new "Makita safety setup" I saw at the Makita road show last month when it went through here.
It works with the electromagnetic energy from your body near the switch and if your hand/finger moves away from the handle for a fraction of a second the brake activates.
It was hard to understand how it works as we were all distracted by the girl demonstrating it. She was so pretty. 
The smallest tool belt I had ever seen.
They reckon it will be incorporated into all electric hand tools in due course.

Chook,how would a small tool belt help with safety switches
Do they promise it will come with the pretty girl with the small belt?? Where do I get one.
so now we have to have special switches to make up for twits being able to operate grinders unsafely.
they will have SPECIAL COURSE AND A LICENCE NEXT!
Unfortunately Paul that has already happened.
That's part of my workplace job.......... training and assessing before the students can use ANY tool they must be accredited.
We live in a NANNY state. Who know where it will end.
Back onto the theme of this thread what are you building guys.
I've been sucked into making 3 veranda poles for a mates house. Mick "Mr Carpet".
This is one, made out of 100mm x 100mm x 5mm wall and they are 11.2 metres long.
agreed with wifey to not build any bikes this year after buying myself a carbon roadie
(my first new bike in my life!!!!!!!!
so ive just finished a 42cm "special" race bike for the lad next door, restored a Giant Yukon MTB for a camping trip , and 1/2 built a small MTB with disc brakes for lil stig , so she can camp too
the micro roadie 8 speed brake shifters,carbon fork
my new MTB.tip salvage ,cost about $25 in new cables
the new carbon roadie$11spd 105...... however,ive earned scorn aplenty for dropping the brooksB17 narrow leather saddle onto the frame . aparently one doesnt do such things in the lycra wearing world.
If anybody actually asked me how it feels i could tell them its like sitting on the silken hand of an angel, but since they dont ask , i ain't tellin'
now Ive got the bikes for the season out of the way, i can clear the shed for some spoke building and a new class 5
Just rebuilt the trailer for my ski boat. It's been sitting in the back yard for approx 6 years unused. Trailer just rusting away. Thought it was time to either use it or sell it. Reused running gear etc
This is how I spent a few of my hours this year while not sailing. It's a re-build of an older electric tricycle onto old kids bikes frames that I scrounged free from the local tip. Speed regulated to under 25kph etc and complies with all the W.A transport department requirements as a power assisted bicycle for unlicenced/unregistered use on roads and shared footpaths. Does about 40km on power only or unlimited distance if I am silly enough to pedal. Cheap as chips to run and keeps the locals smiling.
During this build was when someone about my size dropped the angle grinder on my leg for added interest!!
PS: If you look closely it's not really a BMW. Cheers....Wok
I am in the process of building a new trailer for my bike for when I do my weekly shopping.
Its to replace the one stolen with my bike from in front of the local cinema a couple of weeks ago. I'd chained and locked it but they used bolt cutters to remove it.
They threw my helmet away. Paul had given me new parts to build a new bike only the week before. Worst thing was that I had fitted the controller for electric conversion to the top bar. So now I have motor + batteries but no controller! Will show pix as I progress.
Wayne, do you still have the rotating hand speed controller or has that gone taa taa with the bike? It is possible that I can copy my solid state controller and build you one. Making a new hand throttle is the hardest part. I'll pull mine apart tomorrow and have a look....Wok
I have the hand controller which is a magfet(magnetic field effect transistor). The motor is a 36v 8wire unit( three phase wires, two power{+and-}wires and 3 fet {speed feedback control}wires. I acquired 6 second hand 36v lifepo rechargeables from someone I made contact with while I was a member of AEVA(Australian Electric Vehicle Association), for the cost of postage
have you had a good look out behind the cinema . I cant see them riding far on that bike.
let me know what aprts you need from the graveyard. feel for ya
