Do you promise that you won't use the same soldering that you use for
plumbing. : )

Not the same soldering as for plumbing? What else?
Just curious ;-)

Here, in the US, copper pipe is soldered together. The plumbing solder used
to be something like 50-50 tin/lead with an acid flux core....

Hi Frank.
You didn't see my smilie? Hmmm?
In germany soldering for copper is somewhat 70/30 tin/lead -much more
tighter than 50/50. 50/50 is only used for repairs on old lead-pipes
wich are no longer used for new pipes since decades here and it has the
flux core in it and looks like VERY thick electronics solder. It's very
tricky to solder this over head. I learned to handele this more than 20
years ago... :-)
On copper we use acid flux with very fine solder gravel in it wich is
brought to the copper skin with a brush before putting the copper things
together. You will have the copper tinplated when heated only without
adding any additional solder.
For electronics I prefer thin electronics solder with 0.5mm (0.02") in
diameter with my temperatur regulated soldering station. Also have 1.0mm
in use for bigger parts like cable connectors or repairs on car-electrics.

Of course not! :-)

Lead pipe hasn't been used in the US for decades, either. Except in
Chicago, where it was required by code for the hook up from the underground
water main to the house. Chicago dropped the lead pipe requirement less
than 20 years ago.

I'm a bit surprised that lead alloy solder is still used in Germany for
drinking water pipes. I thought the Europeans had been more agressive in
their concerns about lead. As far as I know, lead base paints had been
banned first in Europe, and there is more concern about disposing electronic
items with lead alloy solder there.

The bismuth alloy plumbing solder I've used was solid core.

The 50/50 solder you describe sounds exactly like the kind of acid flux core
solder we kitbuilders were warned not to use.

On copper we use acid flux with very fine solder gravel in it wich is
brought to the copper skin with a brush before putting the copper things
together. You will have the copper tinplated when heated only without

Yes, that sort of flux is commonly available here. It works well. And
copper pipes are always cleaned, then fluxed with external flux before
soldering. Solid core solder is prefered for plumbing because it doesn't
feed in so quickly, but acid core solder produces just as good a joint.
Acid core solder is better for general purpose work, such as soldering sheet
metal with a torch. If a handyman has only one roll of solder, it's
probably acid core.

For rosin core, I just buy the thin stuff. I don't like having extra spools
of solder around. Good thing I read the warning about acid core solder!

Hi Frank.
We are going way too off topic....
When you come to Berlin one day we may have an extended talk in my
living room. You're invited for a coke at least.
I have to push my vocabulary used by handcraftsmen... ;-)
You may bookmark the reply adress of this(!) posting for private mail.

Be warned. They drink Coke just like beer, room temperature.

I have a microwave oven ;-)
I don't know about beer because I do not drink beer. It does not taste
to me... But Coke has to have 2-4 degrees Celsius(!).

On our honeymoon trip of 5500 miles through southwest US in summer of
'87 we had to get crushed ice twice a day on the gas-stations to keep
our Coke real cold. :-)

Cold Coke and no beer? Are you a traitor?

A traitor of what?
For sure I like a good wine or a pure whiskey (without ice and coke)
sometimes.. :-)
I do driving a lot for buisiness and privately and like driving. And I
do never drink _and_ drive. So I drink alcohol very seldom.
Just got my "new" used Volkswagen T4-van on friday.... :-)
