• Thanks very much for your thoughts and suggestions - much appreciated.
    I was thinking of filing down the slot, but the ideal position would mean taking the spot between the bottom of the slot and the bottom of the braze on thus compromising the braze on totally, but I suppose if a bodge as per ^^ was done then it may not affect the strength of the braze on, however, I may as well then get the whole thing removed and stick a band on instead.
    It is about 14cm from the bottom of the braze on slot to the bb centre so it doesn't seem abnormal.
    I am going to see if I can get a cheapo 53t off ebay and see if that makes for an acceptable arrangement - but then I guess there may be a problem with switching to a 34t inner. Gah.
