Tetrode, what did you do to prevent the speedring from spinning around the adapter?
I'm not sure I'm understanding your question. Do you mean how do I prevent the speed ring insert from turning? With the insert I'm using, once the four retaining screws are tightened, the insert cannot turn. I secured the insert in the correct orientation to ensure the Speed Pro would align properly when mounted.
Also, the speedpro bracket accepts umbrella rods, were you able to mount your 86 PLM in there?
The Speed Pro umbrella holder doesn't work particularly well right out of the box:
Technically, the answer to your specific question is, yes, I could
mount my 86" PLM using the Speed Pro's native umbrella holder. I certainly wouldn't want to, though, because of the bracket's inability to retain an umbrella shaft parallel to the Speed Pro's track.
With the PLMs in particular, a better solution is to just use the supplied "cage":
PCB doesn't offer a Bowens compatible "cage" but modding either the AB or Elinchrom cage is a piece of cake if you can drill three holes:
To be able to use umbrellas other than (more accurately, in addition to) the PLMs successfully with the Speed Pro, I went to the considerable trouble of adding a proper umbrella holder to the bracket:
