Over the years, many clock movements have come and gone across my bench. One type that always got to me was the kind that has a hole through the end post for the levers and such. I've seen some debate on here (long ago) about what to use and what not to use. The "what not" to use were tapered pins because the larger end of the pin could interfere with movement of the lever or what ever else could come into contact with it, especially when some novice doesn't trim the pin a little shorter. The other method was to take a short piece of wire, bend a hook on one end, insert the opposite end through the hole, and then bend that end.
But! In cutting that wire, you leave it sharp on both ends, and you snag your tender flesh on those sharp ends. And then, you want to try and leave that bent wire so it lays flat up against the lever or such so it looks nice and doesn't engage your flesh when you brush against it. So you install all those little bent wires on all the posts of the movement, and find out you need to remove a few of those wires a little later because of an adjustment, a problem or whatever. Tiny pieces of wires like this get lost on the bench, fall to the floor, etc. Reinstalling them can be a pain also.
I remember on some clocks there were little linchpins that held dial posts to the movement. I had saved some and decided to give it a whirl. I bought some more at an auto parts store. They are easy to put on, and to take off. when positioned properly, there should be no interference with other parts. I have never seen these used before, other than to hold dial posts to the movement.
So that is my "horological heresy". What do you think?...........................gary
