Alternative timber to replace vertical bamboo?
Posted: Tue Nov 16, 2021 3:17 pm
I am looking for a suitable timber to use in laminated bows once my stock of vertical bamboo is depleted.
Previously I have successfully used hard rock maple but I was looking for another alternative.
Has anyone used Australian white cypress for laminations?
