"Today was one of those days - 2 steps forward, one step back. I almost gave up at one point but I wanted to press on. I did manage to get the remaining verticals cut and tacked. Three of them are angled so that took a little more time. I was hoping to get as far as the firewall today but it wasn't to be.
I really like the procedure that Paul Minegla used to set station B-P so I did the same thing. I happened to have a partial sheet of 1/2 plywood in my plywood rack that fit perfectly to use as a jig. That station was layed out in place on the plywood then tacked. The cross tube at that station is important to place correctly and level because it is the bottom of the instrument panel. The plywood makes the layout fool proof (almost!).
When I was making the angled verticals for station B-P I completely missed the fact that the verticals angle in slightly from P to the cross tube. I was using the figure of 42-1/2"" at both the top and the cross tube when the cross tube should have been 41"". I cut the angle and welded both tubes and made the fish mouth cuts and had it secured to the jig on the frame before I realized my mistake. I was getting ready to scrap both pieces when it dawned on me that I could re-cut and weld the angle because it would actually add some length. That worked out fine until I was trying to refit the first corrected piece to the wrong side. I realized it before I screwed it up too much. With the verticals corrected I fit the cross tube then tacked it all."
