Glue for stavework mugs

Exactly... I'm using RLO :)

Certainly if they were completely period, there wouldn't be glue used
and they would be coopered. I'd certainly be interested in photos of
the tankards :)

So raw is safe and boiled is poisonous?

Raw linseed oil is just that. Oil extracted from the Flax seed.

BLO is not "boiled". While boiling some oils does change their
characteristics, BLO is RLO with several chemicals added to make it
cure faster. The additives are almost all certainly poisonous. I have
read some sources which claim that the poisonous heavy metals all get
contained inside the finish when the linseed oil cures, but I wouldn't
trust it after looking at all the nasties that get added.

You can buy food grade linseed oil (You can even buy it at health food
stores as flax seed oil). It takes a few weeks to cure, but possible
health concerns should be well worth it.

Especially walnut. It is not uncommon for woodworkers to develop
an allergy to walnut.

Epoxy would seeem to be the glue of choice for the staves. Cured
Epoxies should be pretty resistant to any chemicals found in a
beverage.

302 stainless steel one presumes. Lead-free pewter might be easier.
You can buy it in sheets that could (I think) be cold rolled over a
form
and the seams soldered with lead-free solder.

Be aware that most (maybe all) epoxies have a 'glass transition
temerature'
around 150 F. They soften at that temperature and do not regain their
properties when cooled.

I am no expert. However, I have three stave-built things in the
house. Two ;tankaard-style mugs and a small bucket. I watched one of
the mugs being assembled. No glue. So far as I know, neither of the
other two uses glue either and it was certainly not the norm for
barrels. FWIW, the tankards I have were made in Japan. I'll post a
picture if you like.

Polyurethane cleans up easily with acetone. Let the mug sit long
enough for the acetone to completely evaporate before applying BLO.

Tried & True makes a line of LO finishes that are made according
to a 19th century recipe, by heating -- no driers added, but it's
claimed it dries as fast as the stuff with driers.


Personally, for a drinking vessel, I'd use epoxy.

Or line it with metal.

BLO? Somebody might be using these things.

Tape the inside staves with blue masking tape. The glue will foam
up attached to the tape. Remove the tape.

That looks like what some people I know in Oregon make, except their
staves tapper.

I do understand the desire not to use a modern finish, but allow me to
explain why I do... I never know what people are going to drink and I
don't know the reaction that liquid would have with linseed oil and the
componds in the wood. Second, even walnut and maple wood have some
compounds in them that some people might react to. The people in Oregon
also was a number of "exotics", which increase the chances that people
could react to the wood. The result is, an interior finish that is
stable and safe.

Also, in my experience, raw linseed oil never seems to completely
harden.

Of course, an authentic mug would not be glued at all. The mug would
be coopered, much like a barrel. There really isn't a good glue for
this, until the modern glues were invented.
