As we started placing and marking final position for turnouts, we were able to mark all the centerlines for cork roadbed. It is always good to mark everything using actual tracks and turnouts. It is possible to have some errors on drawn plan (depending on the templates and software you use). There were no major errors, actually only one which was easily corrected by curving one straight piece in very gentle curve.
Cork is glued on one of the loops (double tracked, more complex one) and interlocking module. Those two are the complex and risky one and because of that by tracing all the lines and gluing cork on them we hit another big milestone. We used regular white wood glue (PVA) and pins to hold cork in place while the glue sets. We cut the cork into 2cm wide strips and glued along both sides of centerline. That way is much easier to bend cork and have naturally flowing curves.
After the glue has dried we cut out all the non-necessary part of sub roadbed plywood. Modules are now mostly very shallow plywood frame and as a result they are very light.
At the end of the day we started gluing cork on second loop (single tracked).
Furthermore, we screw small wood screws into tops of the module end plates (two on each end). Rails will be soldered to those screws to keep them firmly positioned on module ends.
