I shortened the bar on both sides and have two questions.
1.on the measurements list under the ht. and width columns, it sometimes puts under the width col. 3.5″. does that mean I’m supposed to lay the 2×4 flat on the ground or stand it up on its edge. 2nd, the #6 middle base support is 6″ long and fits between the #3 and #4 pieces, but it seems to be too short. I can’t figure where I’m messing up.
