Thread: SEMI OT - how NOT to cut branches down.

#### that a bit scary that heaps of stitches. Isn't it funny sometimes we just do things without thinking. Scary thought..

When I was doing the training course to be the workplace OH&S rep, the presenter used an example of the circular saws with guide fixed open and on switch tapped on (was going into and out of a table) that was inadvertantly used by a 2nd person. Had it on the floor as he plugged it in, it jumped and cut his leg off!

My Father near lost a leg when he was ripping a sheet of ply - the saw hit a knot and jumped into his leg (Dad decided later that the spring on the saw must have gotten tired, so that saw was retired permanently btw). Only thing that saved him was his strange practice of always having his (overly packed) wallet in his pocket, even when doing stuff around the place, and it had some coins in it - they got shredded, and it defected the saw down his leg, rather than its initial trajectory that was going straight through. Even so, the damage was significantly worse than a skinning.

Fair few hundred stitches later, and a semicircular scar the size of a 7 1/4" blade to show for it.

One of the tug skippers here in Newcastle is called Captain Craw
He climbed a tree sat on the branch , the tree side , and used a circular saw one handed to cut the branch off , took his thumb off and part of his hand as well , They managed to reconnect it and save the thumb but the nickname remains

I really wanted to have a cool and very witty reply, but I am just speechless... :eek: :confused: :eek:

Same bloke by any chance? :eek:

he's crazy too..lol

At least the branch won't fall on him but certainly mad.

It never fails to amuse me how people think they have the might of Atlas to stop a couple of kg's worth of spinning blade simply with their bare hand(s) in the slightest of a second. Be it a circular saw, or in the case of richard cranium with the chainsaw and no foot hold consider newtons laws:

Newtons first law states that "every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it." Thus, once the circular saw or chainsaw passes uniformly through the tree, it's force is then affected by gravity or by a kickback force associated with a pinched blade. Either way it tends to commence it's path of travel back towards the unwary user (either in an arc or in a more direct line of sight motion)
Second law: Force = mass x acceleration. Gravity or the power of the motor during kickback accelerating the saw towards the user now combines with the mass of the saw = force. Typically the force exerted by the richard is less than the force exterted by the saw. Now Newtons thrid law takes action, where the typically wide-eyed richard cranium exerts an equal but opposite force back against the blade, normally with some part of the body...

Nasty one, Stu.
