Hey Will,

Could you please point me to a source(s) that can 1)explain/walk me thru the type of calculations you did here for my post size in regards to height, load, and removal of wood after joinery, and 2)list the various values for different species of wood. I want to qualify my feeling that Oak and Hemlock will work structurally with a taller kneewall, especially if Oak will be used for the posts in the middle bent. In the meantime I'll see what I can find.
