Homemade metal cutting saw

Wouter writes – “Home made metal cutting saw. No welding required. My wife’s grandfather made lots of his own tools, this is another nice one. This metal cutting saw uses an abrasive disk spinning at about 5000rpm. Because of the big pulley on the motor it’s all pretty quiet. This machine offers no protection to the operator. Do not copy the design without adding a belt guard, blade guard and other safety measures. “Link.

  1. I’d add a belt guard, a momentary switch on the handle and modify the table a bit to include a stop on the back. Otherwise if used with proper respect it looks like a decent tool.

    kurtronix, et al.
    Why the fear? Besides polish, the only difference between this tool and the commercial offerings is that with the commercial you (or your next of kin) have a company to sue if the tool malfunctions or you make a mistake.

  2. As Hammerthumb notes, the saw is not fundamentally different from any other abrasion cut-off saw. There are many commercial versions available.

    The only differences are
    a) there’s a full guard around the belt, as I recommended in the notes,
    b) there’s a double sided guard around the cut-off disk, and
    c) there is a spring or some other mechanism to keep the cutter in the ‘up’ position by default.
    These are all easy modifications.

    The machines I’ve posted were all made by a depression-era, do-it-yourself guy who grew up on a farm. Safety was not necessarily his strong suit.
