rescuing a cracked kuksa?!

[forrestdweller]

recently i made my first kuksa from a seasoned (scrap) piece of oak but sadly it developed a crack when i used it the first time (""baptizing"" it with hot mint tea boiled in my billy over the campfire).... . is there a way of sealing the crack?! bit of a shame to have it just siting around for decoration....

Cyanoacrylate (superglue) is good. Flood the crack (put a bit of masking tape on one side to stop it running out). Leave to dry, top up if necessary and sand flat. Will work on fine cracks - don't know how bad yours is.

thats what I did to may last one when I noticed it starting to crack seems to have stoped it from further cracking...

If it's just a leaking crack try boiling in milk. Lot on here recently about that.

If bigger, I've used epoxy and brass powder. Sands down nicely (eventually) to a gold finish.

Worth a try.

Cheers

I repaired one of mine with epoxy, first drilled a small hole at the bottom of the crack to help prevent further spliting.

Try Sugru!!

So far everything I've tried to fix with it has been successful

Another way it to use wood glue.
You first hold the crack "open" a bit and force the glue in to the crack with your nail. then clamp it or hold it close until the glue dried.

superglue sounds like an idea- is it suitable for food related items?!

the crack is only visible when i have (hot) liquid in the cup and disappears again when it's empty.... . i guess it might have to to with how the grain of the timber ""runs""---> hot liquid causing stress in the timber...

We have an old maple butter bowl with a crack that was repaired by inletting a couple "butterflies" across it. Hourglass-shaped pieces of hardwood. The repair adds to its character.

Its fine for food use - I've done it myself. It sounds like something is expanding and contracting with heat in an uneven way. The superglue may hold the crack together - but if the stresses are too great any glue can rip away.

Still - there isn't too much to lose!

indeed nothing to loose so i'll give it a try and see what happens- otherwise it will make a nice measuring cup for dry cooking ingredients...
