    Dangerous homemade grinding/chainsaw conversion

    I am the first to rebut the claims that homemade tools are "dangerous", as people roll their eyes, wondering why everyone would ever dare to build a tool instead of buying it.

    On the other hand, there are some genuine gems out there of truly dangerous homemade tools, and this is one of them. There's so much sketchy stuff in this video, it almost seems planned, as if the tool lobby is organizing an information campaign against homemade tools.

    When watching that on YouTube it suggested the following link that shows you how to make one.

    It actually seems to be well enough made. I wouldn't have any reservations about using it. There is a company that makes a similar attachment for circular saws and charges $130 for it. It is used to cut mortises in beams for log construction.

    The first chap seems to be wearing sensible trousers and boots unlike the one I found who's wearing shorts.

    Here's the main criticism: no brake, no chain catcher, and the chain moves whenever the tool is powered, as opposed to using a centrifugal clutch that does not engage the drive when the tool is idling.

    Less important, but still worth mentioning: no safety gear, and wobbly methods for securing the logs. To their credit, the second video does show a guard that they made.

    More stuff, some admittedly nitpicky: https://en.wikipedia.org/wiki/Chainsaw_safety_features

    In the first video, unless something is happening off-camera that we can't see, the tool is converted without ever unplugging it.

    Despite all of this, it's still clever, and this concept can be harvested for "idea value" for making various homemade tools.

    Surely the centrifugal clutch is not a requirement for electric chainsaws there is no idle

    Valid point! I've never used an electric chainsaw.

    Although I agree that the on off switch you commonly get on a grinder is not appropriate for a saw. If you let go it should stop.

    You can do it the other way too, which is arguably safer: chainsaw-to-grinder.




    You may laugh, but at least the guy above is wearing shoes. Here's a nice one with sandals, balancing on logs:

    Lyckily both of those angle grinder- saw conversions seem to be without any chain lubrication, so lets hope those broke before accidents happen. ��
