Drawing Corrections
Eccentric Rod Length
Error noted on drawing AH8 - eccentric rod is 11-1/8 inches long not 10-1/8 inches long. I spent about 3 hours chasing it down today. I would hate to build this without first modeling it entirely in CAD. I had to scale the print to find the error.
Rod Interference
Found another fairly obvious interference issue. The reversing shaft interferes with the coupling rods (see drawing AH14).
I had just completed an animation of the Baker valve gear when I noticed it. The Baker valve gear was a quality job except for the eccentric rod and drop arm.
