The last detail that I wanted to add to the underside of the bridge was some thinner cross bracing. I used this image of the CNJ's Newark Bay Drawbridge as a guide.<!-- m --><a class="postlink" href="http://lcweb2.loc.gov/cgi-bin/displayPhoto.pl?path=/pnp/habshaer/nj/nj0800/nj0876/photos&topImages=112212pr.jpg&topLinks=112212pv.jpg,112212pu.tif&title=10.%20%20DETAIL%20VIEW%20OF%20FLOOR%20SYSTEM%20FOR%20210'%209'%20LIFT%20SPAN%20%3cbr%3eHAER%20NJ,7-NEARK,16-10&displayProfile=0">http://lcweb2.loc.gov/cgi-bin/displayPh ... yProfile=0</a><!-- m --> I didn't want to put too much detail into it as it can only be seen when the bridge is raised, and even then, it's still not too visible.
after that I started on the counter weights. Once again I went to the library of congress web page for Ideas. I used the same prototype for inspiration, <!-- m --><a class="postlink" href="http://lcweb2.loc.gov/cgi-bin/displayPhoto.pl?path=/pnp/habshaer/nj/nj0800/nj0876/photos&topImages=112217pr.jpg&topLinks=112217pv.jpg,112217pu.tif&title=15.%20%20DETAIL%20VIEW%20OF%20MAIN%20AND%20AUXILIARY%20COUNTERWEIGHTS%20FOR%20299'%20LIFT%20SPANS%20%3cbr%3eHAER%20NJ,7-NEARK,16-15&displayProfile=0">http://lcweb2.loc.gov/cgi-bin/displayPh ... yProfile=0</a><!-- m --> I did change the look a little but you can still see the similarities.
They were cut from some .015 styrene and braced with plastic straws on the inside.
Here is the almost finished product of one of the main counterweights. I added the small aluminum blocks on the left to the inside of the weights. This added some heft to the otherwise light box. I felt it would help to keep the "wire rope" stretched when they're installed.
