Thanks, guys, but I have to give proper credit....I stole the idea from Bob Willer :-) I use 1/4" wide masking tape, layered from the start of the easement transition. Offset the start of each successive layer to get a smooth transition into the superelevation -- I found between 1 and 2 inches works best. I use a digital level to determine when I have enough superelevation, but usually about 12 to 13 layers does it. As an aside, I used masonite spline for subroadbed and homasote roadbed. The masonite was glued together using industrial-strength hot glue, and goes together quickly. The downside is that you must sand the top to get a smooth surface. Unfortunately, that sanding combined with the uneven thickness of homasote, creates lots of opportunities to perfect your shimming technique (and your langauge skills). It also makes installing the superelevation challenging. I initially tried using stripwood as has been suggested, sanding the ends into a smooth transition, but once track was installed, the variations in roadbed created enough irregularities in the track that I had tracking problems with longer cars. Using the digital level to measure the actual superelevation, I was able to fine-tune the numberof tape layers to accomodate the roadbed irregularities.
