I'm trying to build round handing signs for over the doorways of my A&P warehouse (see http://www.the-gauge.com/showthread.php?t=12926) in N scale. I have the signs themselves. The problem is....how do I construct the sign supports? What's the best material to use to get the basic shape I'm looking for? I've tried thin styrene rods, but they're pretty flimsy. I was thinking brass. Any ideas? Just to clarify, the round sign itself is about 4 - 4.5 N scale feet.
