Oops! I skipped a post. In the previous post I mentioned sanding the cork roadbed. After receiving comments on the railroad forums and PMs asking why and how about sanding cork roadbed I realized I had failed to include a post on the subject before pronouncing the roadbed finished. So here goes an out-of-sequence post to make up for the oversight.
No big deal really. All I did was run the belt sander over every bit of the roadbed and then used the time tested bodyman hand sliding feel across it to make sure it was flat and defect free. No different than shaping body filler with an air file. Ah yes, the good ole days in the bodyshop. After the trip around the layout with the 50 grit belt sander I followed up with 120 grit by hand on a flat board to remove the fuzzies left behind by the 50 grit. Once happy with the results a quick vacuuming finished the task. The roadbed is smoooooth and super flat. Should make a beautiful surface upon which to lay track.
