  • mini circular bench saw from scrap [UPDATED]

    Very interesting, but I think this could be a bit on the dangerous side. Having nearly cut the end of my left thumb and index finger at the second knuckle off about 20 years ago with a very similar home made tool, I would advise caution and some modifications with this instructable. The cutting wheel side of things is completely exposed, and the table is particle board. And putting fasteners into wood when mounting an electric motor is not going to last long, with every jolt from the motor starting the wood around the fasteners will wear a small amount causing things to loosen up over time.

The cutting wheel side of things is completely exposed, and the table is particle board.

With a power tool, the cutting wheel/blade/grinder/etc should be enclosed to protect fingers/rings/shirt sleeves/etc from being caught as much as possible. The case and all points where the motor mounts to it should be metal. And some provision should be made to securely mount the tool on a bench or sturdy stand. Great idea, but please be careful if you build this. Better yet, go to lowes or home depot and get one of many inexpensive saw options with the REQUIRED safety features. Just one opinion.

    The problem is, your BRAIN doesn't always protect you from accidents, particularly when the is an exposed spinning wheel that can catch a shirt sleeve or a ring, or long hair. It's a POWER tool and they can be dangerous even in experienced hands. An electric motor doesn't stop because you get caught in it. Common sense is part of using tools responsibly. Even still, I think it's a good instructable!
