Because he hasn't asked folks to go help him build benchwork for them... When you announce you're working on a project, and people go out of their way to help you (either physically and in person, or by posting useful information) and then you simply abandon it, you shouldn't be surprised when people take issue with each new project announcement.
get off your horse Ed - i've thanked those who've helped with time, effort, and information. what exactly have i abandoned? i have the benchwork that Brian and Lee helped me with - i didn't NEED help with that, i could have used dimensional lumber, but it was about more than just building some benchwork - learning, sharing, eating - you know, being social. Mr. Smith has been an invaluable resource, the exchange of ideas has helped others i'm sure. not every plan is a home run, and sometimes, you don't see that until you have the benchwork up and the plywood cut. i was talking with Eric this afternoon and my quest to build a layout has been an evolution in thinking - moving from HO scale required a new approach - it easily allows for more action in the same space of HO, but it's best tempered. the balance of operations to running to scenic elements is difficult to "see" when switching scales. i know what an 18" or 24" radius looks like in HO, i don't know what that is in N scale - i don't have 25 years of N scale experience.
so forgive me if i've aired my "growing" pains as i've come to terms with what is and is not possible in N scale. i didn't mean to offend your sensibilities. i'll try to enjoy my hobby on your terms in the future.
