i am noticing now the stick is starting to get straighter and straighter. I don't think im over tightening it, is this just something that happens over time. Do i need it re-haired or do i need a new bow?
What is the bow stick made from? It might well be brazil wood, which is much softer and less resilient than pernumbuco. Brazil wood sticks do eventually lose their 'spring' and three years is roughly their life span.
A rehair will not return curvature to the stick itself and unless the bow is valuable, it won't be worth having it re-shaped - which is done using a flame, heating the wood and literally bending the stick while it's hot.
Time for a new bow I think.
NB. to all readers of this post. DO NOT try to reshape a bow stick yourself at home. It is a skilled job and you will damage your bow if you attempt a DIY.
