The Italian postal service isn't exactly the Pony Express. The last three items I've bought were instantly mailed and they are projected to arrive in mid October. While a lot of their parts are new old stock and in very good condition, of what worth are they if you cannot get them in a reasonable amount of time.
Andrew stated that the Cinelli stems used 26.4 mm bars. Now that sounds close enough to 26 that you could tighten it in but no, you can't. You have to find Cinelli bars. There are a lot of Cinelli stems advertised as 26 mm but apparently people do not know how to measure since they will not tighten onto 26 mm bars.

Hell, you want to try dealing with the Chinese postal system and their export inspections, presumably to avoid foreigners stealing Chinese technology -- which in the first instance they stole from those foreigners. Or the Greek post office which is so ill-informed that they don't even know Ireland is in the EU, and Greek customs who are outright crooks and will never admit to making a mistake. You won't have any hair left after dealing with either the Chinese or the Greeks. The make the Italians look angelic. Which is why I prefer dealing with the Dutch and the Germans and the French, especially now that it is so expensive shopping in England because they're no longer in the EU. -- AJ

Classic Cinelli stems (#1, #1A, #1R) were indeed 26.4mm and
yes you really do need 26.4mm bars (or a piece of a 0.2mm
feeler gauge)
Later Cinelli products (1E) are 26.0mm stem and handlebar.
Changed in the 1990s.

is advising his riding companion that he can stop his BMW's handlebars from slipping by cutting a
shim out of beer can metal. The BMW guy refuses. He seems to think using beer can shims on
a BMW counts as desecration.
(My BMW, from that era, has bars that have never slipped. But I used to teach freshmen how to
read micrometers, calipers, etc.)

I discovered some Cinelli bars owned by what sounds like a UCBerkeley student and he will sell me three of them. Hopefully I can pick them up today so that I can put the Moser together. Those carbon fiber bars are slipping no matter what steps I take. Plus they are making cracking sounds that are worrisome though are probably the bar slipping slighting in the stem which is coated with carbon paste. Sunday I

Heh-heh! On RAT (rec.audio.tubes) there was one idiot who bragged of his MSE from Stanford, much like the RBT credentialist slime brag about having passed out of community and other no-count colleges better known for producing shoe salesmen than engineers. And then this moron, name of Henry Pasternak advised a newby to load a power tube with 1x impedance. Oops, guarantee of a spectacular, expensive, possibly lethal failure! His excuse was that he suffered a mindfart "in my zeal to flame Andre." He never lived it down. He was so pompous and his single amp design was of such turgid cookbook dullness that I christened him Pompass Plodnick. And then he advised the rest of the gang be belonged to, the Magnequest Scum, when another member challenged me to a design contest. An engineer who had a better grip on the numbers christened my amp "Andre's Hedonist's Delight" and I christened their expensive challenger "the Bubbaland 300B Noisemaker" because it had about a hundred times the residual distortion of my amp.

I don't think dissimilar metals (316 stainless and aluminum alloys),
which are at opposite ends of the galvanic series, is a good idea.
0.20mm aluminum shims are available:
<https://www.amazon.com/10pcs-0-2mm200mm200mm-99-6-Aluminum-Sheet/dp/B07G2WFVY2>
<https://www.amazon.com/SOFIALXC1060-Aluminum-Aluminium-Material-100Mmx1000mm/dp/B08FRBG9Q2>
I just did a crude test to see if a soft aluminum shim would cold flow
under compression. Nope. The surface areas and stem bolt location
don't produce enough pressure (psi) to squash the shim. However, the
edges of the shim will get squashed by the handlebars as the rider
alternately applies and releases downward pressure. It might be
useful to extend the shim slightly beyond the edge of the stem.
I've seen people recommend aluminum foil or aluminum duct tape wrap
for shims. Every time I try to use foil, it eventually tears and
becomes loose. Bad idea because it will require 8 to 12 layers of
foil. Maybe some glue between layers, but that seems like
it might make a mess when compressed.
Heavy duty household aluminum foil is 0.024mm thick.
A 0.2mm shim would be:
0.20 / 0.024 = 8.3 layers of foil
The commodity household so heavy duty stuff is 0.016mm.
A 0.2mm shim would be:
0.20 / 0.016 = 12.5 layers of foil

An actual feeler gauge is $3~$4 and you won't use all of it.

What is a 1x impedance? Impedances are measured in ohms. Perhaps you

I tried typing the alt code for omega on my PC keyboard (alt 234) and
cut-n-paste but kept getting an upper case letter "O" in Forte Agent
news reader:
<https://softwareaccountant.com/omega-ohm-symbol/>
However, it worked just fine from the command line and in various text
editors. Probably related to lack of Unicode support:
<https://groups.google.com/g/alt.usenet.offline-reader.forte-agent/c/5Xq78kR64Po>
It is possible to drive a 1 ohm load with a power tube, if you have an
appropriate step down transformer to match the tubes output impedance
to the load. The problem is the output current through the 1 ohm load
would probably be high enough to justify using welding cable.

I don't drink booze. Fruit juice or carbonated sugar water cans
should suffice. Good idea.

(salt water) and we have corrosion. Some sort of plating, paint,
paste, putty, glue, etc, to prevent electrolyte from entering between
the dissimilar metals might work, but I don't think it's worth the
risk. A shim made from an aluminum beer can will eliminate the
problem.

has long been known. You make a shim out of an aluminum can. "I have a
26.0 Cinelli bar in a 26.4 stem with a beer can shim; have ridden
thousands of miles on that bike w/o a problem," see
<https://www.cyclingforums.com/threads/cinelli-26-0mm-in-26-4mm.309136/>.
I would also suspect that the Nitto steel shim, that is used to go from
a 26.0mm stem to 25.4mm bars would also work.
