This is a slightly exploded view of half a table top. The semi-lunar center is to be 3/4" MDF veneered on both sides; it is 24" in radius. The outer ring is to be quarter-sawn oak 3" wide (24" inner radius to mesh with MDF to 27" outer radius) with a 1" inner shelf for the MDF to rest on. My plan is to glue the ring solidly to the MDF. I have used this technique on many smaller tables without any evidence of splitting or separation. Is this technique viable on a tabletop this large?

Don't bother with the shelf. Just biscuit the edge to the panel. Works fine in these dimensions - we do it all the time.
