I built the table for a lay out yesterday evening with the help of my 3 year old grandson who was mad cause he was wearing his bob the builder hat and i didn't have one. I'm going with a 4x10 for the time being. I must say that the cultivater I built looks a lot better than my wood work. I still haven't decided on a track plan but i am thinking about the one from that greatest hobby vid with a few changes unless someone has a better idea
