We have two of these Strong Pedestals (picture from a post by Steve K)
I need to readjust the image position on the screen but don't quite understand the adjustment assembly design. The large threaded rod obviouslly adjusts the table up and down by the turning the nut. But then behind it is a smaller threaded rod with its own nut that is clamped to the cross bar. What does this do and why is it needed? It looks to me as if someone adjusted the main, larger assembly without adjusting the smaller rod and now the smaller rod is slightly bent (the one in the other pedestal is not bent so I am assuming bent is wrong). I loosened the smaller rod and nut (which was no easy task trying to get in there with a wrench) so that it has no tension on it. With that, the larger nut adjusts the table and thus the image position without any problem. So what's the function of the smaller rod? I don't see it.
IMHO, the whole thing is poorly designed to begin with. To get at the large nut on the adjusting rod, you have to open the control panel (which, if you want to keep an image on the screen to see what you are doing, is AC live), push it out of the way but if it is wired tightly with little slack, it won't swing all the way open, so you have to avoid electrocution while working with a big metal wrench right in that vacinity. Then, they put the adjusting rod and nut in tight against the metal side of the pedestal so that the jaws of the wrench can't properly fully engage the nut, so you wind up making little turns instead of being able to make a proper turn of the nut. This causes the wrench to slip on the nut and cause scrapes and scarring of the nut.
I know you only need to make this adjustment very rarely, but still, it doesn't have to be such a chore if it were better designed. Gimme Simplex's nice big ole adjusting wheel any day.

. But I do agree with you 100% about the lack of quality of their stuff. The part I hate about those interlock machines is the stupid Moviola clutches they stole/adapted into it.... those were not designed for turning a full 2000' house reel and can barely do so! That base is deplorable too... weighs a ton because of the steel bottom plate but in many ways is still not very rock solid.
