Can Plastic Cut Wood?

I made an invisible saw blade to see if it can cut through wood! Maybe the world will be a safer place with this invention. We tried plastic wrap, glass, and plexiglass to see which transparent material works best.

There's finally a maker channel that makes me feel like a genius.

I like that the premise of this video is that "if people can see what they are doing they will get injured less" and he proceeds to make a frag grenade

[@Ryder7223]

Oh course! What better way to avoid touching something than by completely removing the ability to see it! Pure genius!

Thanks mom!

Bro boutta make his hand invisible too

Real sawblades have splayed teeth with sharpened edges. The splay of the teeth is wider than the rest of the blade. This both reduces friction and binding against the bare wood, but also helps clear the saw dust which causes a lot of friction and binding as well. It also exposes more cutting surface area which is the main advantage making for more efficient cuts. Perhaps by making a two half mold, one for a each side of a real sawblade, and heating a transparent material to malleability, and by using weight or a powered-press to compression mold the material into a more accurate sawblade, there might be better results.

The idea of a glass blade scares me. I've been cut many more times by glass than I ever have been by all my power tools combined.

This video made History!!! While watching it, I said out loud to myself, "That is one tough piece of Balsa!" which is the first time that's ever been said in all of Human History! Well done, crew!

I love how you can see that these "sawblades" are more an equivalent to shovels than saws. It doesn't cut as much as it chips the wood and then flings out big chunks of wood at a time

I like how that box was made with a slot in it but it was backwards lol. Then they still use the box and just reach over it only exposing the arteries in his wrist. Genius I tell ya

Machinist here. There is a secret to cutting using hard tools. It's fixture rigidity. If you ran the same tests again with glass blades in a stiff slow moving rig it would cut.

[@Heptofite]

pine is actually a softwood, and balsa is a hardwood. it turns out the definition isn't really about how hard the wood is, but about the way the fibers are laid out or something

If you ever try the plastic wrap again you might try a t-shirt heat press. It has a controllable heat setting and will apply even heat and pressure. Just make sure you put in in between two sheets of parchment paper so you don't melt the wrap too the press.

The hole in the middle should be round so the bolt won't catch like its supposed to and create a point-load that will shatter the glass. Make the hole bigger and use a thick rubber o-ring to keep any glass from touching metal

You need to start a museum of stupid ideas. I'd visit. This one cracked me up, I even had to take cover on this side of my computer!

Thanks, Mom!

My man has developed a blast shield case for his chop saw...

[@zippylamb]

You should do an episode testing saw blades cut from different metals (lead, brass, tin, aluminum etc)
