I have seen this happen if the washer with the flats inside has rotational play on the shaft. If this has play it will loosen the lever a little bit each time you shift. This happened when frame builders use braze-ons from suppliers other than Campi.

Probably a much-answered question, but here it is:
Here is a mid-80s set of Super Record down-tube shift levers. Following previous instructions, I've gotten them as dry and clean as possible on the inside, and believe me I've tightened the right lever more than finger-tight--even used a small hex wrench to crank some more. But there is still slipping under pressure (standing up on uphills especially).
Is there a trick to make these hold? Is this age and wear or...?
Thanks,
Bill
Ps I have the impression from a few emails that I should introduce myself, since I'm new to the list. My first "real" bike was a mid-60s Frejus, old-style crankset 45/54 and grease nipples to boot. Stolen in 1974; I hope someone has taken care of it. It saw a lot of nice use in the Santa Monica Mountains outside L.A. in the early 70s. After that, a 73 Raleigh International for many years (I've always been a recreational rider) and lately a binge-and-purge succession of Windsor Professional (now in the window at Encino Cyclery, if you want to see it); a 73 Masi in A+ shape (sold; $1300); a mid-80s DeRosa (ditto; frame only $425); two red 'n' black 80s Raleigh Racing USA bikes; and (whew) a Miele and Gios, both late 80s and very enjoyable. At 53 and working in hi-tech I don't get out for long rides much; mostly commute to work and cruise about on Sunday.
Thanks for all the good news and advice.
