Today , I will show you how we can saw a wood with paper! You may think i was kidding, but I don't. We really will saw wood with paper and the paper will serve as a saw, as if it were a saw blade and that tool I will use to make this saw blade?
I will use a micro grinding is this little machine here and it spin 32000 times per minute 32000 rpm And. . .
. -. to give you an idea if we divide it by 60 533 rotations per second It's very fast!
and . . .
I will use only a small piece of cardboard which will serve as saw blade first I'll do a circumference of about 4 cm radius or 8 cm (3,15 inches) in diameter then I will cut with scissors to fix the tip of my tool I'll use two little discs that is just to support the paper and it does not get soft then I'll screw the tip of the micro grinding and just to give a "tchans" I'll make some saw teeth here You are not putting faith that cuts here, right? I'll put the goggles because it can fly a piece of paper if it does not work And I will start cutting the soften things Like a Styrofoam cup So. .
. , as styrofoam cutter is a beautiful round piece of cardboard Let's see how it behaves in cardboard He began to get better the game We will now test with a wooden sheet Of about 1 mm diameter 1 mm (0,04 in) diameter 1 mm thickness Oh, boy! Let's increase the boldness now: a pipe of PVC!
We will combine the PVC pipe seemed to butter my saw Let's try now finally with a broomstick As my saw is already half impaired, I'll change the paper disc with a new Fulfil promised, huh? If it was me who was watching, I took a like! Two things!
First . . .
if it serves here for something Whether it is worth even make a paper saw to cut out things very worth it if you have a micro grinding If you have a drill, it does not work because the drill. . .
What I have here, at least, runs up to 2000 rpm This one runs at 32000 So. . .
For micro grinding work, yes I'll never cut PVC with "cegueta" Cause it's better the finishing, cuts much faster using a sheet of paper (#ÉNóisHTLE xD) Second thing Paper is half soft, paper is not as hard just to cut things What happened here, the paper worked as saw? The explanation of this thing is weirder than we think I'll show with a nut hanging this woolen yarn here If we turn the nut You gonna realize that it tends to escape the whirl, right? So I'm spinning here, I have to hold strong here in the middle nut to not escape If I drop the nut, for example She escapes to the circle edge that she was forming You realized that what leaves the nut escape is the line How much faster I spin the nut, more this line will be stretched, the harder this line will be And that's what happens in our paper saw blade It's like having various nuts here at the edge, which is the mass of the paper itself, right?
