I am doing some track planning, at this point I'm just layout out the benchwork edges. I have a protrusion to deal with. It's a solid concrete post, probably rebar reinforced, load bearing, and definitely not modifiable. Don't even think about cutting into it. I need to narrow the layout width at the point that it squeezes past this protrusion, and I want the layout wide enough for a pair of parallel tracks. 

HI Folks:

Hopefully going to start cutting wood and building in the next day or 2, and I have been wondering if cork roadbed on directly on the 1/2 inch plywood or if putting 1 inch of pink foam under it first (allowing me to carve creeks and rivers and other depressions is the way to go.

Ive in my other thread about cork / homosate ive gotten a variety of opinions, and I've decided that Homosate is out for sure, but I'm curious about using foam, and how to secure track if I do?

Thanks

TIM

I am at the point where I need to put up a backdrop on my peninsula.  It is a 2x4 type wall.  Past layout I used masonite hardboard - but i can't remember if i used 1/4" or 1/8".  My studs are on 24" centers - i am concerned that 1/8" may end up being wavy once put up?  

Curious what other approaches you all have used.  I could use drywall for the straight areas and masonite for corners.
