Tetters,
i agree with you. In some times a detail made out of wire instead out of plastic is the far better choice. As with plastic there is standard styrene (PS), cheap, superior glueablility, but prone to break. Then on the other end polyethylene (PE), also cheap, unbreakable, but unglueable.
And there between these two extremes the so called engineering plastics, in comparison expensive and according to the type affectionate either to the glueable/breakable or the unglueable/unbreakable end.
Here at the exposed spots the metal parts cut in. Thin brass or nickel-silver wire is simply more rugged and if anchored into bores onto the body even still more rugged. Remember the old wisdom of glueing; the stability of of an glued joint depends strongly onto the seize of the available area.
In the case of the steps out of engineering plastic there are the bugbears of a only very small adherend, a badly glueable plastic material and a exposed position. No wonder the parts were departing like interstellar rockets if "looking to sharp" on it.
And to your work tetters, as we Germans have a different definition code for acclamation as Canadians,
"hervorragend" means really the highest class of praising.
