In my plan below, on the middle table, my track... starting at the 0 elevation point, climbs steadily to 3 3/4ths inches then levels off for the bridge over the lower track. It stays level across the bridge and then starts it's drop back down to a height of 3 inches..
figuring on the 'decline' stopping and going back into level right about where you see the red arrow or just past the turnout for the passing track, but just before the turnout for the siding. This is just about 5 feet from the bridge to that point and a 3/4 inch drop. I'm making the incline out of a single piece of 1 inch foam and I'm placing foam supports about every foot. The only way I can figure it is that if it's a 5 foot long run is to divide 5 into 3/4ths and I come up with less than 1/8th. Thats getting pretty hard to measure and accurately cut out of scrap foam for the intermediate supports. The logical way to do it would be to pin down the top of the incline on the upper support (by the bridge) and at the bottom and start placing foam blocks underneath and building it up til it touches the incline. Is there a good math way to do this or is it so close just do it the 'eyeball' method?
Also, this incline has the passing track on it. The mainline track has a 22 inch curve radius. I'm new at this so imagine my surprise when I learned my inside passing track can't be a 22" radius also. Not and stay parallel to the main line anyway. I wanted to keep the same radius though so I have more clearance between the two tracks on the curve and that's how I've drawn it out on the benchwork and it looks like it will work fine as it joins back into the turnouts. Am I doing the right thing or is there something I'm missing?
