Working on a giant bow to beat Allen Case!
willie:
strains for the few larch and DF bows I have tillered were about .6 vs .7 for birch, for the same amount of set
sleek:
You may consider white oak? I know its used as planking for plank on frame ships. They like to get the planks long, so perhaps source boat lumber.

You were able to get the bows to 0.6% strain and live? That’s pretty impressive. I keep my hardwood bows around 0.5%, depending on species & condition.

avcase:
White oak would be great choice!
Badger:
If possible I want to make the limbs 1 solid piece. I plan to use 2 timbers about 6" or 7" thick, 2 feet wide and 32 feet long attached to a stationary center piece about 20 ft long. I am open to a stack leaf design if I can get it to work right. I am hoping for a draw weight of about 8 to 10,000 pounds and about a 24 ft draw length. I plan to draw it to destruction going up incrementally until it fails. Hoping for a little over 100,000# stored energy.
