Last year John Heisz replaced his table saw blade with a paper disc, and discovered it could actually cut through wood. This month two different YouTube channels, "The Q" and "Mr. Hacker," put paper wheels into their angle grinders to see what other materials they could cut through:

While the food stuff is a bit silly, I was surprised to see what clean cuts the paper discs made in the polycarbonate Coke bottle and the corrugated cardboard. I also didn't think it would penetrate the coconut shell.

Obviously the big problem with a paper blade is blade wander. I was thinking that if they reinforced both sides of the blade with large arbors made of a stiff material, and with a smaller diameter that left just 1/2" of the blade exposed, that might keep the blade tracking straight; but then you'd lose depth-of-cut. Do you have any ideas for other ways to stiffen the blade?

am engaged in cosplay and I would like to note that given these videos, I could use a sheet of paper in full to cut out some details of EPS. I use it when I do bulk things. Engaging in crafting sometimes has to do a lot of unusual things, from the staffs of the priestesses of Elune and ending with various ornate crowns, cuff links, weapons and other things. But there is one point, on some models (for example, as mentioned in this review, https: //www.bestadvisers.co.uk/angle-grinders) and on my grinder too, a sheet of paper it will be inconvenient to use because of the protective arc ( I have it, for example, and it can not be removed). For example, I made a blade from the League of Legends game. Which could be cut out with paper) p.s. Dude using this blade on the scene is me))

Gee guys, very snazzy but if it is slow and does not cut straight.....??  Maybe in some desperate situation where you have a grinder but no blade.  Just get a thin segmented diamond blade, they're cheap now.  You'll cut straight through whatever and it won't blow up in your face.

What about adding duct tape in the middle section, previously to the circle cutting process? 

How about using a gelatine size. I've sized handmade paper with a gelatine solution and been surprised at how stiff it can become depending on your ratio of water to gelatine 

It took me a few days watch this because all I could think was how much more worried about paper cuts I would be!

Well you could soak it in resin, but at that point it sorta becomes more phenolic and less paper. 

Well anything else simply becomes - let's use a better cutting material.  Potentially introduce glue to the inner part of the ring to stiffen up. The heat from friction might see it melt but that's an option.

I’m a lapsed industrial designer. I was born in NYC and figured I’d die there, but a few years ago I abandoned New York to live on a farm in the countryside with my wife. We have six dogs.
