ok! Railings!
I lay out the frame for the box that goes on the inside of the railing. 8' 2x4 cedar boards at top and bottom, 29" pieces at each end and in the center.
then, on the outside they get a 38" piece that will sit flush on top of the outer frame. and a 49.5" that goes down the side and bolts on. I beveled the edges of those 1 1/2" from the end on a 45 deg angle.
Then I attach the balusters. I cut 2 triangular pieces of scrap wood at 3" width, and centered them on a baluster and screwed them in. I use that to space my balusters. i flip it over for each new baluster because there is a slight difference in the width of the two spacer pieces... this keeps that slight diff from growing into a noticeable one. I also check for plumb with my level after 8 or 10 just to keep on track.
