More Roadbed!

As we explained in a previous post, we're using cork for the roadbed, gluing it to the plywood base with brown silicone sealant.  We had traced the planned rail locations using a pounce, or dressmaker's wheel, and then darkened the lines made by the pounce with a marking pen.  Following that, we inserted push pins at the mid-point of the lines, spacing them about every six inches or so.

The yard section of the layout, with push pins marking the centerpoint of the intended rail lines.
Then we laid out the cork against the push pins, cutting it to shape where needed to fit the turnouts.  We pinned the cork into final location to ensure that we had everything cut to fit the way we wanted it. 

A section of cork cut and pinned into location, ready for gluing.  This section will become the logging camp when the layout is finished.
Then, we lifted the cork sections and spread silicone sealant generously in the spot where the roadbed was to lie.  We pressed the roadbed back into position against the pins marking the center of the rail lines and, again using push pins, tacked the roadbed firmly down to the plywood base.

Because the silicone sealant is messy and because it was often easier to smooth it into place by hand, we wore gloves.

Neatness didn't count here.  The fact that the silicone was spread around the plywood won't matter once we add scenery later.  We intentionally chose the brown sealant so any of it showing through the seams in the cork would not detract from the earthy appearance of the roadbed.

We laid one section of rail to test our planned method for joining sections on curves.  Since most of our layout is curves, this is especially important for us.  The method we'll be using is to stagger the joints in the rails by about six inches so no two rail ends appear side-by-side.  Although this is somewhat non-traditional, we feel it will make it much easier to avoid kinks in the rail at the point where joins occur.  Our test proved us right.  The fit of the rails when joined by our method was perfect and should lead to no derailments at those points.

 In our latest session, we managed to get all the cork fit into final position and glued all of it except the yard portions.  We'll finish those in our next session and then start laying rail.  We're pleased with our progress and excited to see the bare bones of the benchwork taking the shape of an actual railroad layout.
