The bridge on my banjo looked like it was sagging in the middle. I thought it was an optical illusion, but when I laid a straight edge across the top of the bridge, it does indeed sag a little in the center. By this is mean the third string is closer to the head than the first or fifth strings. The head tension doesn't seem loose.
Is this normal? I suspect the downforce on the third string is greatest because the string is in-line with the tailpiece. Should it distort the shape of the bridge?
I don't think so. I would take off the bridge and check it against a straight edge. That is the purpose of the center leg and why old 2 legged bridges usually distort and break. I think you can only tell what's going on if you take off the bridge and check the feet and top. Maybe a bit of sandpaper on a flat surface would do the trick but you have to determine if the issue is the top or bottom.
