Thanks for the kind words. I am enjoying it. The weird thing is how accurate it needs to be. Unlike house framing, where window openings are called "rough in" for a reason, the window openings in the coach framing are the actual window frames. The window sashes are 1/4" narrower than the nominal openings, and there are leaf springs on the sides to keep them from rattling. So at most there is 1/8" to play with -- over a 40 foot length.
