ted, pls help me get this right...

definition of swamped rib: where the top rib lies below the top surface of the barrels...

concave rib, where the surface of the top rib is not flat and appears to be scooped out at angles between 180 ane 360 degrees...

which begs another question...what is the opposite of concave?

reverse concave? crowned?


keep it simple and keep it safe...
