I purchase the Kreg Projec Hole Plans CD. I am in the process of building the workbench. However after reviewing the PDF files on the CD, it don't see the dimensions and layout of some of the parts. In particular the square end frames C, D, E. Does anybody know the LxW of these pieces. The PDF projects plan are not that well written/organized and leaves a few things out like the lumber/cut list! Any help would be appreciated or pics of owners building the workbench ((#WB02).
