Thank you friends, very much... I will keep them coming!
randman - I am glad I can give back something to bowmakers comunity. When I was younger I was just taking, now is time to give some expirience. I use B-50 for lighter bows and ff for heavier.
sa- just do not overdraw them during tillering. The saplings we work on were bended by the wind without problems- why making them into bows would change anything...?
The groove you see is place where I chopped out it's spoongy core.
