I will make this modelling thread totally relevant by declaring that we are,
of course, modelling only the DL&W, Erie, and/or EL!!

Jeff's masking tape technique for super-elevation is a terrific variant with
wide applicability. I just want to add that I found masking tape to also be
a fantastic leveller along with dial calipers. Using 3/4" ply as a
subroadbed and Tru-Scale wood roadbed, I became aware with my fingertips at
first and then with the dial calipers of how much variation there is in the
thickness of these products from piece to piece and even on the same piece
of plywood. If you join them from below, you can get a sudden "step" on top
that really does not sand down too neatly. Strips of masking tape underneath
on the less thick piece where the joining piece will be, especially with the
plywood, provide the equalizer -- so that instead of a "step" one simply
gets an imperceptible little gradient between risers (assuming the
difference in ply thickness is not outrageous). Usually after getting the
thickness equal on the calipers, I'd add one or two more layers of masking
tape to allow for the compression from power-screwing. With the Tru-Scale
roadbed, I'd usually try to simply match the ends before doing any tape
routine. Simple old masking tape! -- a great item for the track laying gang!
