Hello,

If you look at images 68 thru 71 you will see three bolts in each
cross brace. These are every 15 inches dorn the full length of the
playing surface. The bolts are in slots which will allow infinite
adjustment including making the surface concave or convex at any point
or along the entire length.

Try doing that with a 3 inch thick maple slab!
