Does not require a "Coffin" to do the torus ... well ... not same kind of "coffin".
1) Make a heavy torus ... thicker and more stubby than you desire. Voronoi encrust volume with 1000 or more points not welding during process. Leave tidbits as separate.
2) Make a new torus with default + maybe 1 smooth. Use it as a CUTTER ... not with cut command but with a new boolean command that might not be on Mac. (Accumulate). It does intersect over and over serially.
3) Remove curtter object and combind new tidbits.
4) Select higher valance edges and then invert. The inverse is all the edges you didn't want that were projected by the cutter torus.
5) Select coincident faces and invert to get faces to STITCH into new manifold lab. Hide the faces that are in coincident pairs. Then stitch. This will almost always FAIL the first time you try it. Now is a good time to save your work.
6) Fly INSIDE your torus looking for faces that should have been removed as per coincident pairings but were not ... probably because of discrete match issues in Wings/MLAB. Remove them by hand uing hide. This is not easy .. but is quite doable with patience.
7) Run clean-up.
Stitch. If fails ... look HARD for a reason.
