|A model abutment . . .|
|. . . starting from this mockup|
Bruce Petty showed how he built a highway overpass with styrene sheet and Rix Products highway overpass components in the September 2011 Model Railroader, and my model is drawing on Bruce's techniques.
|.040" styrene sheet on the top and|
ends, .080" sheet on the outerwall
|1/4" square styrene bracing--|
stiff and strong. Grrr!
To really add some beefy bulkiness to my abutment, I added bracing with 1/4" square styrene strip. The abutment is quite solid and heavy as a result. This sucker will not warp or even flex.
Next steps: filling and finishing edges of the abutment and preparation for painting. Then the actual span and a support pier. Stay tuned for more.
