I thought I would share with the forum my layout design and the current progress of construction. I love going through this thread and seeing all the great work and ideas people share with this community. Please share your thoughts and considerations.
First images are the 3d model in sketch up of the full layout.
The following shots are the current construction of the ramps and the bridges. The ramps were CNC'd in xps foam and the bridges have been laser cut from 1/8" mdf. Slope of ramps is 2% total rise is 6-1/2"
2x4 benchwork with (1) layer of 1/2" osb and (1) 1/2" layer of homesote on top.
