    yup thats the one that wont stay engaged

    we've found the problem tho
    the lever that controls the cross feed travel has a part broken on it
    the engagement dog on the inner end
    thanks for your interest

    Operators who don`t know what they are doing break that bit.The newer machines have various interlocks and people force things.The favourite here is to try and force the long power feed on while the handwheel is still engaged with the rack.
    I`ve got a manual for one of these but seem to remember there`s not much in it.
