I've been struggling with laying flex track on 1 inch blue foam board for about an hour, contructing a simple dog bone design that covers almost 16 feet on my new shelf layout. (I'm only test fitting to see if I can make the layout I designed on the computer work on the foam...so nothing is being glued/nailed down yet.) It seemed like to even get the track to connect, I had to cut away the first couple of ties since the track connectors wouldn't go under the rail and join with another section. Then after getting a few feet connected, the rail connectors would widen out and come apart - usually when I was trying to get another section joined. Am I doing something really wrong with this flex track? Is there some secret to using it that I just don't know? Should I have pinned it in place to hold everything still while I joined pieces? It was really frusterating trying to get this simple dog bone up and running. I finally succeded, but it wasn't easy. So all you flex track wizards - what's the secret to using this stuff? I really don't want all the joints from using six inch snap track - I've got to make runs of almost 16 feet - so flex track is the way to go...I'm just really bad at using it effectively.
