Working on another trilam. Osage, red elm, and boo. 68" tip to tip.
5 3/8th" brace height here. You can see there is still a slight bit of reflex out past mid limb.
Here it is with a 6.5" brace height and tillered to 22 inches thus far. You can see the limbs are pretty much straight now. That is normal for this design.
Here it is after tillered to 22 inches. Still has a nice reflex at the tips.
