Ash are becoming extinct here also.Many many very large ones standing dead.It's a shame.
An Amish family who have a saw mill I know personally make all of their buggys from ash for frames.They use expensive plywood too.Average base buggy costs $6500.00.They've sold them for over $10,000.00 though too.
They do buy parts for them like springs and wheels though.
Pretty sophisticated buggies with battery powered lights and even kerosene heaters.
After construction they have a paint booth.
I keep a lot of straight edge grain ash strips for backing bows.
They were fascinated watching me bend wood with a heat gun.A few of the boys in that family make bows through my assiciation with them.They still prefer to use compounds though.They don't want to go through the practice of shooting to achieve accuracy.
