    A friend gave me a microwave oven
    Im thinking to use the transformer to make a mag drill
    And the rest of the oven to make an electrode oven or a something like that
    Any other ideas to use it ?

    Would it go "ping" when it drilled through?

    Sounds good, if you're not familiar with dismantling them watch out for the insulators, contain nasty stuff that you do not want to breathe in.

    That used to be true but not so now. The beryllium oxide in the magnetron ceramic insulator has long sonce been replaced by aluminium oxide.

    What you do need to be aware of is the potential for a large shock from the capacitor if the oven has recently been used.

    When was 13 I build my first welder from mots burned in a day ,I think that I made something like 4 stick welders before to got a proper one
    Then I made two spot welders ,a battery charger ,an insulation transformer ,some inductances ect..
    I know that is not a good idea crush a magnetron
    Generally I cut the copper wire to allow me to extract the dangerous part and recycle the magnets
    Now for the mag-drill I will use the transformer ,I will cut the welds and extract the secondary winding without cut it
    Now the question is which kind of drill use ?
    Was thinking about concrete mixer or something like this to have low speed and high torque

    I made a little Rod oven
    Now I'm studying for the mag drill I think that the biggest problem will be to make the the electromagnetic contact surface square with no gaps

    I started the project of the mag drill
    I simply tear down the oven and put out the transformer .
    Removed the secondary winding ,power on using a car battery ...
    Is a single transformer enough strong to control the moment of the drill?
    I saw the video and he used two mot
    I tried to pull the transformer but I moved the bench so I think that is enough strong
    But I'm not sure what do you think about?
    So have intention to use metal only for structural parts of the project ,an a use an elettrician box to put into all the wires the AC DC adapter the SCR controller and the switches
    Was also thinking to put a safety switch on the contact plate as if the drill jumps it will automatically get off
    So a safety features

    ive got one of these

    https://www.ebay.co.uk/itm/Hand-Dri...445422&hash=item3b20cff1be:g:Cv8AAOSw5sBbhlR4

    as your drilling it comes loose as you put pressure on it or it slides up with the plastic nothing worse than that drill spinning and it coming loose

    strengtheners to keep drill in line and also easier to fasten the front plate usine the lathes method of a slider with even a lathes cogs and tooth bar is what id consider

    Still micro wave related.

    The glass platter is great when chilled, to serve cold drinks on. Plus great to serve cream cakes off as well.

    The door micro switches are a 3 way small switch, great for projects.

    The magnets great to make a earth clamp etc.

    The thin metal, when cleaned makes great welding practise.

    Timer switch can be used, as a timer.

    If it has a grill that makes a great small paint oven.

    I think that is to dangerous for me
    I don't like guns
    Or better I love guns ,the history ,the mechanism how they works etc
    But a weapon is always something born to kill so nothing good can be make by any kind of weapon

    Magnets im looking for a use
    With the grill and the rest of the oven I made a little rod oven (180°C or something like this)

    So little test this morning
    Put the mot on the welding bench
    Used an F clamp as an handle
    Used a 1¹/4 inch tube and a prybar as a lever
    Put my own weight on the very end of the lever after gave power to the mot
    I used 12V 4A
    This little thing is powerful I think that can manage the power of a 1600W drill
