ty, the bow is 57 lbs at my draw length of 29.5". I shot 500 grain arrows through my chrono, and it averages 164 fps. I'm not sure how good that is, but compared to the 1st bow I made this one seems like a rocket launcher.
I've only worked with yellowheart a couple times, but I did some research before I started the bow. It has fairly straight grain, and from the 10 boards at the hardwood lumberyard, I was able to find 2 that had straight grain running from the bottom to the top. The growth rings are subtle, but you can definitely see them. It has diffuse porous grain, as is common with hardwoods in tropical climates.
You can see the rings on the belly of the bow, and the pores on the knife handle :D
