Finished the warp last night.
Not sure if the middle space is the best for the sectional beam. If not, I can
always change it and fit it to the top space (mind you, I'll have to
take some of it apart again). I've added an extra beam, that way I'm
free to warp whichever way I want.
Tomorrow I'm going to the grandchildren so, the warping will have to wait another day.
