Hi guys, with the purchace of my new laptop computer, im able to get rid of my bulky computer desk to free up ATON of room in my room lol. I will also be getting rid of my dresser and TV. Goin to put my clothes in the closet and im getting a 42" plasma screen TV. My dad suggested that I should build a small shelf around the room. The only reason he said this was because of home much ive been complaining an dtalking about building the layout i planned a few months ago. So I went with his idea and though up a cool plan. Ill have a 15"-18" shelf that goes all the way around the room. Ill mount it on 15" heavy duty shelf brackets. It will be 48" off the ground. Where the shelf will cross the door I want a lift out section. I have never attempted one before so im going to hope you guys can help me thru it when I get there. I also am going to have a under layout staging yard. I plan on a 3% grade going down from the layout to the yard and back up from the yard to the layout. I will use the WS 3% inclines to achieve the climb and the decent. My question is, how much room should I leave between the the layout and staging yard? I think i can get away with 6" between the levels. Will that be okay? I know that might be a little difficult to set-up the trains but...... What would you guys suggest?
