heya Folks> just planed up some really nice quarter sawn oak for my outer rails (8 1/2' boards). Would like to know opinions on where to place scarf joint. Should I just join in the middle or would it be better to leave the middle joint free and join on both ends to make up the 151/2 feet required. Also...I was thinkin of cutting a rabbit in the outer rail so the top edge of the plywood is covered......thoughts????
