recut the two frame threads for the nearside footrest outrigger/swing arm clamp thing. the screws were stiff all the way out and then wouldn't go back in without flattening the thread. It must have been overtightened last time someone had the swinging arm out. lovely now. can't do much more just yet because my arm's in a sling but am basically replacing a lot of rotten stuff ruined by 16 winters of commuting. .
