I have a berimbau verga that has cracked at the top. I've tried to glue or tape it it back together but the wood keeps cracking apart where the leather is nailed in. Does anyone have any suggestions for repair?
The pressure that is generated from the string (Arame) is high and constant thats why your tip keeps cracking, If the broken piece is not too big I would suggest to get rid of it and try to make a new tip. The sound won't be the same (it will be a bit higher) but it's a solution.
