Simon sorry to hear about the stave. Were you working to build a bow out of it or was it still air drying and started fretting? How were you going about tillering it since that can cause some problems?
I hadn't started tillering yet, just thinning the sapwood. I'd been a bit hasty with the wood - it was in the log for 6 months, then a stave for about 4, then bow sized for 2 months. I'd also brought it in to the warm house to work on it. I'm hoping it will still be ok as the major problem is a split in the sapwood at the nock area ...if I glue it well, maybe the string will sort of hold it together?
I have another bit which is two years old now and definitely dry. Possibly a bit brittle though. Do you work with yew?
