Nested Sets and a BOM with subassemblies

I get the concept of nested sets as presented in the examples. The problem I have is making the leap to a BOM where a given part can appear in multiple places.

partID
rightEdge
leftEdge
...

isn't going to work so what am I missing? I thought about having a table of parts with parent data and table that just has the nested sets. But, then I'm back to recursion to populate the sets table.
