what to do with ipe

It glues up fine if you use a solvent to remove the oil the wood produces from the surfaces. It is hard and so heavy it sinks like a stone if dropped in water. Ipe is pretty stable once it's fully dried, shrinkage of boards that haven't been properly acclimated is the only issue. It's so dense it doesn't absorb moisture from the air like many woods so seasonal movement isn't a problem. It finishes well but you need to use a good sealer to lock in the oils that will cause most finishes to bubble and peel. It's a difficult wood to work with but once a project is completed it's as durable as concrete. Have fun and have some extra blades on hand, you'll need them.
