OK! I finally think i established the draw length. I did some scraping and then sanding to lighten the bow. I can draw it to 21" now, and anything after that is a wall because of the short limbs. Yes this bow stacks badly, but i was shooting it today with some makeshift arrows and it's definitely fast, but the arrows are divine crap so they go anywhere but what i'm aiming at. Don't worry, there's a rudderbows shop relatively close by so i'll buy some of their wooden arrows which i like a lot. I'm going to keep the bow as is, because looking at the limbs i think their working quite a bit, especially at the weight its at. If anything i'll just lighten it a bit more. I'm looking forward to making a longer bow, but these shorties are really fun to make and i am impressed how much serviceberry can take. Plus it helps me learn alot. Right now the bow is 60#. here's some pics of my draw after i scraped, its probably a good three inches longer than what it initially was.
