Hmmm a valiant atempt, but it will fail, i see the arm you have cut away, you plan to glue an arm on the other side? is that correct? not a hope, the glue area is too small, and that plastic is difficult to glue at the best of times,if thewire leg is secured into the body, and will pull out, better to find a mate with a lathe, and have him make a double sided arm for you, with a boss that is drilled and tapped for a short grub screw (the type with no head, just a hex hole for an allen wrench) this can also be brazed or soldered up out of sheet steel, and a metal wheel collar,
