I have a Peugeot PX10 from the 1970s, which makes a dandy touring bike.
But I'm not so young anymore. I converted it to all Campy many years
ago, but now want to put a triple crankset on for loaded touring
without going broke in the process (TA would be nice, but would cost
more than $300 once I finish paying for the new bottom bracket,
chainrings, etc.--if anyone knows where to get a triple TA with French
thread for cheap, lemme know). Any rate, what I'd like to do is replace
just the spindle, keeping the existing Campy cups and bearings, and
then throw on a Sugino or equivalent, i.e. affordable, triple. Is this
possible? Anyone know what spindle would work with the Campy bottom
bracket and a crankset with a 30-tooth inside chainring (or even
lower)? I want something with a 52 tooth big ring for when the wind's
at my back and a granny bail-out gear for when it's not. Any other
options to get me to my destination for $100 or so would be much
appreciated. Thanks.

I think you're on the right track with the Sugino idea. There are some
serendipitously compatible Campy-Sugino combinations, though they may
not be the ones you'd need. I'd check with Andy Muzi at
yellowjersey.org, who sells the Suginos and knows about BB-compatibility
issues. He might even be able to supply a French-thread BB cheap, who
knows, although Sheldon Brown seems to specialize more in the
French-thread stuff (http://www.sheldonbrown.com/harris/).

Once you get the crank & BB sorted, you *may* need a new front
derailleur, and almost certainly a new rear one, unless yours is already
a long-cage affair.

Good luck,
