I tried to repair two osage bows with similar breaks, I used urac glue and a superglue soaked serving thread wrap to put them back together, both failed in short order. Both of these bows had over 200K shots through them when they broke, the owners shot them almost every day, one for 5 years and one for 8 years before they blew. The one that shot his for 8 years stopped every day at a public range on his way home from work and put 100 arrows plus through it. If he shot it 300 days a year that's 240,000 shots. Osage is amazing!
