People, don't do this. It won't work as an appropriate table saw, will overheat the driver and rapidly discharge the battery.All you may end up with is fingers cut off from inappropriate use of a saw blade and driver. And why the word "hack"? It used to be "tip." Hack sounds like you're doing something illegal. I laud your creativity and effort, but this rig isn't safe nor will it work properly.
Good comments. Best rule of thumb: so you can keep both of yours, use tools only for what they are intended. As for the word "hack," while it might be appropriate for these dangerous projects, it shouldn't replace "tip" generally. I get tired of seeing it.
