I would also thing that the tops of the leg assemblies have the same kind of tusk tenons. This would make the leg assembly entirely independent of the top. That way if you bumped the top, all of the leverage would not be stressing the legs, some of the energy would be absorbed into the top and it might slide just a tad. A very small tad.
This gets us to exactly how large of a man are you? Even the components of this table will be heavy.
This trestle table could be a lot of fun to build. Everything is separate.
The two trestle legs, 3 stretchers and the top. Oh yeah, the top, hope you have large friends to move it.
