## Summary

Mike Pekovich and Aneesa Capsales discuss the structural integrity of end-grain glue joints following Patrick Sullivan's viral video, concluding that while end-grain glue is strong, wood movement and long-term stability make it risky for critical joints. They advise on joining long runs of crown molding, suggesting scarf joints or breaking up spans with architectural details to avoid visible gaps. The hosts also compare floating tenon systems like Festool Domino and Biscuit Lock to traditional mortise and tenon joinery, recommending routers for beginners seeking strength and versatility.
