For gobans I made, I used isosurface objects:

Two half of sine a sphere for the foot:

  function {sqrt( x*x + y*y + z*z ) - .9 + abs(sin( 4*atan2(x, z) )*0.1)}

(the two half spheres are on top of each other and top one is scaled 
down along y).

One sine-cylinder for the leg:
  function {sqrt(x*x + z*z) - 0.9 + abs(sin(4*atan2(x, z))*0.1)}


I will post the image in p.b.i so you can see the result.
