Panic over, the local woodyard did all the calculating and cutting for me.
So what kind wood are you using? I think it would be a fun project but I hate sitting in them. My dad made a pair of Adirondack chairs and I didn't like to sit in them and I was a boy.I have been asked to make two adirondack chairs. Thats 44 different sized planks. if I get the timber wrong I could easily be losing money. Any programmes to organise for mimimal waste?
