I been tinkering on my project all spring and summer long. Bought several new parts to use to better align the center spar. Also got the living room dining room and big bedroom remodeled since the begining of the year. With the new parts the spar is exactly where the plans show within less than a mm.
Took me a while to plan the bottom work.
Both side Center Spar supports turned out natually symetical. No forcing the two sides into plum.
