Agree with TampaJim. Epoxy is a bonding agent, not a mechanical filler. Any glue joint, lesser is better for stongest joint. Best scenario is a slip fit of the reel seat to the blank. Next best is a full contact slip fit of an arbor to the reel seat and arbor to blank. Realize these are not always possible, but gear any solutions towards thin layer of epoxy if at all possible. Glues are designed for thin layer application for strongest mechanical connection.
