    My toaster resurrection project :)

    Need to (re)connect the nichrome wire to the insulated, stranded supply wire.
    The existing (now overheated and useless, due to heat via bad connection)
    connection is a rivet (stainless?) with the nichrome wrapped around the head,
    and a brass (looking) crimp on the backside that accepts the supply wire.

    Barring an original replacement item, what replacements would you recommend?
    Most crimp ring terminals aren't brass. Should I use brass? A rivet would be
    difficult to install here. Would a threaded fastener (nut & bolt) be
    sufficient? Stainless?

    Thanks,

    those are specially rated terminals and wire ... a first rate
    appliance repair shop would have them and might sell you a
    few..otherwise search google.

    brass and copper wont work unless plated, ni chrome or silver
    usually. the insulation is special also

    Can't use anything off-the-shelf?
    Don't need more nichrome or supply wire; there's enough slack to make it
    work. Just need a means for connecting these together through the mica (?)
    composite backing board.

    Thanks,

    How do I determine that it is plated? As opposed to ... just a bare metal
    sleeve? What plating?

    Are the common plastic-covered crimps (which, of course, will be used sans
    plastic) plated? They seem to me to be made of softer metal that would lose
    its strength when heated. How to tell if a particular crimp is suitable?

    Thanks,

    This is what I used. Found plated crimps at local appliance "fix-it" shop.

    Used short length of 14 ga solid copper wire between supply wire and nichrome
    wire. Two crimps, one for supply-to-solid wire, one for solid
    wire-to-nichrome.

    Looks solid and works. Time will tell.

    Thanks to all who contributed ideas.

  6. I needed to repair a 1955 toaster element after someone stuck a
    fork in to remove a piece of stuck toast. First time, I used a
    small steel washer folded in half and effectively used as a crimp.
    That repair lasted about 25 years before the nichrome wire burned
    through at the edge of the washer (probably the contact got bad
    and it locally overheated). I've recently repaired it again with a
    tiny crimp cut off the end of a crimp connection washer, which I
    suspect was brass. I scratched the nichrome wire clean where it
    went into the crimp, but I don't know if that really makes any
    long lasting difference.

    If you're playing this game, think carefully what the consequences
    of the join breaking are, and the nichrome wire contacting the case
    metalwork. In a British earthed toaster, this is not much of a safety
    issue, but I wouldn't dare do such a repair on a US toaster which is
    likely not earthed anyway, and even if it is, the outlet might not be.
     
  7. why not brass and copper, many terminals for copper wire are made from
    brass, and copper is widely used for connections
