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

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

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!

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 a thought !
What to do when there's not enough wind
EAT BEANS

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.

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
