@Rebelwork beautifull bar, I like all the profiles, belvenie 12 is just a bonus. Nice! You glued tiles on with some universal glue? I like that edge is made of wood.
Anyway, yeah, as discussed, holding power is my concern regarding rabbets, but if many of you have good experience with it, then it surely has to hold. Especially reinforced with dowels.
I know it's not as strong as dovetails and I doubt it's as strong as with box joint like mine up there, but if it will hold regular use, it's good enough for most projects.
