Here is the image I drew the pans from. I haven't seen the actual piece so I
suppose it is possible that the original is 30" high - a table you could sit
at, but that would make the top 3" thick. I have drawn it 18" high with a 2"
thick top 36" in diameter which I think is very likely how it is. A table
for my house needs to be smaller still so I will probably scale it down
further and make it 24" diameter when I come to build it. It appears to be
made of clear knot free deal. Would the experts agree?
