I'm trying to support a couple loops of track with a circle under the track. These loops are used temporarily for testing, and stored up against the wall. The circles would be approximately 18" radius but open in the center to save on materials and weight. To do this, I plan on cutting straight segments with the appropriate angle to approximate the circle.
However, it seems that all the joints on these segments would lead to a rather flexible circle, so I'm looking at my options to stiffen the circle. The two I've come up with thus far are cutting twice or three times the segments required and overlapping the joints (basically building my own plywood) or using some kind of bolt and nut system to keep the joints together.
Are there better options?
