I have been using homasote spline for about 8 years, it has been trouble free. I ripped the 4X8 sheets into 2in wide strips, then cut grooves in the splines at about 1 to 1 1/2 inch intervals to make it more flexable. I glue the strips together in place and use clamps and/or drywall screws to hold it in place until the glue drys. Once the glue is dry remove the clamps/drywall screws and smooth the top surface with a Stanley Sureform tool. If any depressions are present in the surface, apply joint compound using a wide tape knife. I lay either cork or Homabed on top of the splines. I have found that the vertical grooves cut in the splines for flexability are unnecessary for my 32in min. radius curves. Tortise switch machines are mounted by cutting an approx. 2"X3" square of 1/4 plywood, run the sureform tool on the underside of the splined roadbed to make a smooth surface, the glue the 2"x3' square to the underside of the roadbed with white or carpenter's glue, screw the switch machine to this wood square. It sounds more complicated than it is. A hole is drilled through the roadbed for the acutating arm from the Tortise through the throwbar on the turnout. Hope you find this information helpful.
