Queensland Rosewood
I was fortunate enough to be given a fairly large piece of milled rosewood. The timber works and finishes well.
The rosewood handle in my latest static tip recurve has accent strips of African blackwood and hard maple.
The handle shape will not be to everyone's liking but I'm happy with the result.

Re: Queensland Rosewood
Riser looks nice Daryl,that rosewood is beautiful stuff mate
Re: Queensland Rosewood
Hi Rod.
At the moment I am not aware of any numbers for it. 'Gut feel' is that it shoots fast and has nil 'shock' with appropriate mass arrows. My expectations are that its arrow velocity(energy)/bow efficency performance will be 'above average'.
Daryl will not say it however, the bow itself looks very nice plus is a pleasure to shoot. The workmanship is high, typical of Daryl's work. It is still in the tuning stage and the grip does not suit me but suits the builder appropriately.LB rod 55 wrote:Riser looks nice Daryl,that rosewood is beautiful stuff mate

Re: Queensland Rosewood
Red gum and milk wood for bow making ? ?

Re: Queensland Rosewood
Red gum for riser maybe limbs and milkwood for arrows
Re: Queensland Rosewood
If from a split bush billet of red river gum, you could remove the bark and possibly use the sapwood for the back of the bow.
A wider and thinner limb cross section is probably the most forgiving profile for this timber.
Milled boards are a little more difficult because of the violated grain. Backing with pole bamboo can eliminate a lot of durability issues.
