As @bwilli88 notes, he graciously dropped off the Peugeot mixte frame at my house this morning, and I got to meet his wife and daughter and give him a quick tour of the bike cave. A few hours later, I started the process of stripping the parts and getting ready to give the frame an oxalic acid bath. Everything came off easily except for the cotter on the NDS arm, which started bending as I went at it. However, given that it was the NDS, I was able to remove the lockring and cup, then pull the whole unit still connected to the axle. And I can confirm French threading as the NDS cup was lefty loosey.

Some pics of the subject before I went at it:

I scoured the basement for possible OA soaking vessels: plastic lined cardboard boxes, building a wooden box, getting a kiddie pool. Then, I realized that in deep storage was a fish tank of appropriate length:

Of course, I'll need to keep rotating and probably could make it twice as deep, but we'll see how this goes for now. Plus the clear glass will allow a close-up view of the magic happening!

I didn't know Peugeot made a white to yellow fade bicycle in the 70s...?

Serious note...will the oxalic acid eat through caulking in the fishtank?

Get the aquarium bubbler going to circulate the solution, it'll help.

aquarium is of a construction termed "all-glass" and is assembled with silastic/rtv sealant which is both the adhesive which holds things together and the sealant which makes it watertight

this sealant should hold up to the OA all right

bent stud on wedgebolt due to pressure which is not directly inline with long axis of pin

if things are well lined up and then maintained during the pressing process this will not happen

Peugeot wedgebolts of course take more pressure than others due to their larger contact area with the spindle

frame looks to be a UE18 of 1970

are shift levers alloy?

old style Juy skewers?

The drop off, and a nice visit to the bike grotto. Enjoy.

How hard was it to get the crank off and the bottom bracket out.

nlerner

Guess we'll see! There's a drain hole in the basement floor just to the left of the tank in any case.

It was actually used as a hamster tank, so no bubbler possibilities. Still, the action is happening quite quickly:


The NDS cotter had a different nut size than the DS, but was not as deep into the crank arm as the DS. One is a replacement. I don't know if I'll be re-using this crankset again (leaning toward an IGH build with a single-ring cotterless crank), so not a priority.

Shift lever as passed along by @bwilli88 is standard Simplex of the 70s. Don't know if it's original. Didn't come to me with wheels or skewers, but Brian might know. It does have a numbered plate on the bottom of the BB though I believe those serial #s aren't a terribly reliable indicator of origin year.

As I noted, one cotter was stubborn, but the cups spun right out.

That's the single benefit of French or Italian BB threading, unless the previous owner used thread locker, which I generally do.

Roger M

Those poor fish.

nlerner

Well, I did have to hold the Park wrench with my Stein cup tool and whack it with a hammer, but it gave.

nlerner

It's the ghosts of the hamsters that I'm worried about.

First results are impressive!

Those threads are getting a nice cleaning as well!

The mixte seems to have benefited from some lovely box lining on the seat "stays" that the other AO/UOs didn't get..... That was a pretty gross start but looks like it will clean up much better than one would think.

markk900

juvela Just a guess but I would put the bike perhaps 1-2 years later than your guess, mostly because I think the triangular shield was replaced by the square shield in 1972 (or maybe 1971). But it *is* Peugeot so who really knows!

thank you so much for your observation!

between the 1971 and 1972 model years they began coming through with the NERVAR chrome steel chainguard which the cycle lacks

the late production model year '71's seem to receive the guard while the early model year examples do not

of course it could have been removed...

one reason asked anent the shift levers is that the 1969 & 1970 model years received the alloy shift levers while the 1971 and subsequent received the black Delrin shift levers with the sheet metal overlay

the latter type first appears in Juy materials of 1970 but does not come through on new cycles until the 1971 model year

always delighted to defer to your vastly greater knowledge on leone rampante matters...

markk900

Or it could be we have narrowed the birth year to 1971!

- agreed!

My awareness of some trivia around this subject pales against the overall historical cycling vault that is your mind and experience!

should they be yet in attendance the machine's Juy Prestige mechs may prove of aid in establishment of a datum, if marked

another tool are the Lyotard 36's

up to a certain date they either came bare or with the bolt-on Cibie reflectors

then they began coming through in one of the R versions

here is the manufacturer's catalogue page for the U.S. market UE8 and UE18 models of nineteen and seventy-one

note how the cutouts in the spider of the drive side DURAX crank arms have already disappeared yet they are present in our subject machine -

^ Nice that they pre-sagged the saddle on that Caravelle!

The Prestige RD that came with the frameset seems to have a date code of 1971.

Oh, and the pedals do have bolt-on reflectors on one side. And, of course, one is missing a dust cap.

Always wanted to see one of these actually built up for and used for touring.

nlerner

Sounds like another good clunker challenge!

Okay, the OA bath treatment is complete.

Before:

After:

You'll notice that the paint on the fork pretty much completely bubbled off (I had to help the last bits with some paint remover). That's not a bad look as the chrome is in good shape. As far as the rest of the frame, the lack of rust revealed that it's kind of a tired old paint job:

I'll go at it with rubbing compound and whatnot (and ordered a replacement head badge), but I don't have high hopes for a fine white sheen without a repaint (which isn't in the plans).

Can any BFers confirm the seat post size for this model? My calipers seem to show 22.5mm, which is pretty odd.

And anyone have some fish that need a tank with some fine accomodations?

thanks very much for the update - she is coming along most nicely!

yes on pillar

saddle clip requires a bolt in shim/adaptor, if not using the OEM clip

some clips produced for use with small diameter unstepped pillars have a tongue bent over their top so there is no chance of the clip sliding down and damaging the saddle

and as with all of the Peugeots with a small diameter unstepped pillar one needs to get the clip nuts very tight to make sure clip cannot slip down and ruin saddle...

greasing the bolt threads makes this easier

I had some time this weekend to commence with the rehab. In progress:



27” wheels, Conti tires I’ve had around forever, Sturmey Archer 3-speed rear hubs with coaster brake, MAFAC front brake, Pivo stem sanded down to fit 22.0 steerer. Still sorting out what I’ll do for a crankset. Perhaps use the original with the outer ring as a bashguard if I can find an alloy 116bcd ring. Or maybe a Stronglight mod 93 w/ one ring as a bashguard. Gel saddle doesn’t look the part, but it’s what I have.

The paint overall is in pretty bad shape with the head tube perhaps the worst of it. I might try for a light touch up to blend in with the rest of the distressed look, perhaps with a brush. I do have a replacement headbadge decal on order.

nlerner

Finally had a bit more time to work on this project. Stronglight 93 crankset w/ single ring installed on a Stronglight French-threaded BB, rear hub had a broken indicator stuck in it, which I didn't realize until last night, but was able to pull it apart today, get some purchase on that broken rod, and spin it out. My collection of replacement indicators is a motley crew (all those little chains seem to be mangled right at the point they contact the axle nut) but found one that works. And I retapped the DS shifter mount to M5 and installed a cable stop. Chain guard is a V-O project, which also took some modification to get it to fit. Those pedals are placeholders as the NDS one is quite bent. I'm thinking of installing fenders and a kickstand, and that should be it.
