I'm having trouble getting the screw from the 13mm tube to be tight with both the shogun inferno and samurai blade, the monitor just spins around. Tried using a few washers, did the trick but is clunky. Anyone else have the problem?
The trick is to not screw the screw in all the way, you just poke a few threads in then when you twist the 13MM post the threads in the monitor jam against the threads in the post and lock the system. It's quite a bit of genius engineering and works just fine if you use the mount the way it was designed instead of the way you think it should work. The head of the internal screw on my rig is not quite flush with the top of the post. If it were not locked up in the equipment locker I'd post a photo.
