I’m sitting in a ditch with the first bow I’ve finished for me...gave my first two away...waiting on an Antelope to come by. I started two years ago. I’ll reinforce...get and read at minimum the Trad. Boyers Bible Vol 1...more you read, the better. I second looking up Clay Hayes on YouTube and you might consider joining his Patreon group. He does a lot of great vids regarding a lot of this stuff...but he has a great series on building bows from Osage. You might have people tell you to start with hickory or start busy building a board bow...it’s probably wise advice. I, however, figured I’d just jump into working with Osage, as this is the wood that really cranks my scooter. I made a couple of kids bows then got 4-6 different bows to various states of completion before making fatal mistakes and screwing them up. Failure is a great teacher! I have places in Indiana and Ohio where Osage is plentiful and the landowners care nothing for the tree. If you take a weekend and ride toward Ohio and scout it out, I’m sure you can find folks willing to let you cut Osage off their property...just knock, chat, and ask. Lots of good videos on harvesting, splitting, and sealing staves on YouTube too. Good luck! You are about to get hooked on something you’ll try to perfect and not quite get there for the rest of your days...it’s awesomely addictive!
