Dilemma... faithfully reproduce the track plan but have to extend the baseboards by 2 inches width, or drop one of three sidings and fit in the boards I have already made?
That's my idea if I go for it, Mr Duck ... a length of 1" square timber along the front and back to make everything fit. Damn that third siding, if I add a kickback siding along the front of the fiddle yard board and blend that into the scenic I could do without the third siding...
