if i wanted to join this vertical piece, is it better to put screws going the red way, or the green way?
Why not both?
>>2964225both obviously? if not around a column red would be the only option.
yes both but i would add a toenailed screw in through the center would maximum strengthsee the blue line in my diagrambe sure to counter sink the tonailed screw though
Green ones should go in from the outside. Red out from the in side.
