    Some Optimus 111C stoves keep coming up on the Bey that are new in the box but have a flaw. The nuts om the fuel tank were never welded to the tank, thus no way to fasten the tank/heat shield to the stove. These stoves sell for about $100. less than one with welded nuts. The 2 bolts and 2 nuts are supplied. Anyone know of a fix?

    Optimus used either Lead/tin solder or hard braze to fabricate their No.111 fuel tanks.
    It is likely that tanks intended for kerosene fuel, such as the original Op.111, were assembled using relatively low melting point lead/tin solder.
    The No.111 stoves intended for gasoline or multi fuel use appear to have been fabricated using the higher melting point, and stronger, copper-based braze.

    Optimus 111 Pump Tube: soldered or brazed

    Best Regards,

    I didn’t see @Twoberth’s post on the insert kerfuffle at the time but it makes good reading. Thanks again George for your powers of recall, helped by an effective CCS search engine of course.
