Elliot, great job, I think you have inspired several of us to try and make one! But I think I will wait and see how Dave does with his!
SO today before work I got a little more tracked laid, secured the track to my second bridge. Wasn't sure how I was going to do it as the bridge deck is metal, but had a brain storm. I drilled holes and use the 2-56 screws and nuts to fasten it down. Worked great cause the size of the screw heads are really small! Stole them from my Kadee coupler kit! LOL
