Last night I said a bad word as my usual attempt to hold a Kadee coupler box together by creating a weld around the edges with a soldering iron failed. Of course the spring went west leading to an interesting time examining the floorside debris ( must find that vacuum cleaner again soon). It doesn't often happen but when it does it makes me wonder why the coupler box could not have been designed to lock itself.
Thoughts of finding suitable screws and wouldn't it be nice to just rivet it entered my mind once again, to be quickly dismissed as usual and then just get on with the job.
Sometimes the obvious finally hit me in the back of the head.
I had some plastic rod that looked about right.
Touch the hot iron to one end to form a head, wait a few seconds, insert from bottom of box in hole (one not being used to attach said box), cut off at top with side cutters, mash down other side of rod with iron until flush with top of box, voila!
You could make 2 rivets if you like but one is enough to enable attachment now or at a later date.
Why didn't I think of this years ago ?? Well, we won't go into that :>)
