This is a miter saw I built for a contest. The blade spins and can cut paper. The best part about it is that the blade guard lifts up automatically as you push the saw down, just like the real thing. Plus, it's huge, heavy, and uses lots of flexi-rods. :-)

Here's how it works; when you push the saw down, fishing line gets reeled out in the back. A shaft turns, which is geared up so another shaft spins faster. Another strand of fishing line is attached to this shaft. When one strand of fishing line gets pulled out, another gets pulled in at a faster rate. One strand goes through the base and up into the saw, going through many wheels (yes, this was very hard to put through the wheels). There's also rubber bands that help reset everything.

Here are the instructions!

Here is the complete parts list, plus deconstruction pictures!

Here's the video:

I don't have any white rods, I ran out of them on my current project. I bought 1000 from ebay, but I have to return them because they were dirty and discolored. :-(

This thing is AWSOME!!!!!!!!5*
Shadowman39 (author)  DontShoot2624 years ago
Ho. Lee. Crap.

This thing is a BEAST. Have you ever tried cutting anything stronger then paper, like cardboard? Or a finger........ What! You got ten of 'em...... Lol, just kidding.
Shadowman39 (author)  videogamemaster4 years ago
Thanks! I highly doubt it would have cut anything thicker than paper.
Your welcome :)

Have you ever thought about using something more powerful for the motor, like, say, a drill?
Shadowman39 (author)  videogamemaster4 years ago
I never thought about using a drill, but I rather use a different motor, like a motor to a weed eater. :-)
Or a chainsaw! Heh heh, that saw would going at like 1,000 RPS!!

But, a weed eater is good, too. I bet you could also sharpen the pieces a little bit more.

Not to ruin your 'ible or anything. Just trying to give you ideas to see if you could make it better.

:O oh buddy this thing is awesome!!!!! i was just about to design one when i seen yours. Great Job, i'm going to try and make one that angles and bevels. 5* keep up the good work!!
Shadowman39 (author)  norton2204 years ago
Cool. Maybe you could add a k'nex motor with a placeable power switch so that the switch is activated when you lower the saw turning the blade? 5* keep up the good work!
Shadowman39 (author)  Matrix-technician4 years ago
Thanks, that's a good idea.
