This might not be what you mean, but I will write anyway.
Some of you looked at the link of my Tower units for big reel projection. No modifications are made to ANY machine used in the Towers. You can run with the rear arm up, but the front arm must stay down to avoid contact with the large upper reel.
The Tower is designed so that the machine is free of heavy take up on the mechanics. That being the projector need only pull the film through, slightly more engery than running with out film or reels.
My only true modifications to any such equipment have been the cradles for 35mm scope lenses, and I have also converted a Kelmar cleaner from 35 to 8/16mm. But that of course, has been done before as well.
The only modification that I have ever done to an Elmo projector, was a private sale of an HD and the unit came to me with the missing white take up roller just before the take up reel. While it was true it was missing and not in the box, it turned out the shaft screw was broken and the threaded hole could not be reused. So I carefull drilled a hole through the main case and inserted a bracket for a 35mm Kelmar roller to take the place of the part broken/lost. It was abit tricky for me as I am not good with these kinds of things, but in the end it worked out well and the Kelmar roller being sealed bearings rotates alot better than how the little white roller would have eveb if it had been complete and restored.

Jean-Marc, people have extended the arms of the GS to use 2,400 foot spools. Not something I fancy doing; I can see the benefit but once done the arms don't fold down flat as they overlap.
John, I totally understand that. But, in case of a permanent installation, this is tempting. Perhaps fitting the arms from a DOA Beaulieu or a Fumeo, even an Elmo 16CL. Although I'm not sure the original motors would be able to cope with the extra weight. Anybody tried this? Just curious...

Modify the threading mechanism so the loop is just held down whilst the auto-thread is required.
Pardon me for being such an ignoramus. I'm not a GS owner *yet* but should be in the near future. So, I'm trying to grab as much details as I can.
Does this mean that, in case of the push-down auto-thread malfunctionning, you need to keep pressing down on that greenish part until the film's run to the take-up spool? Or is it risky?
I'm asking because there's, for instance, a slight misconception regarding the Beaulieu 708. People think you can load manually. Not quite. Well, you can but it's tricky. Some sections are so narrow (particularly the one leading to the sound heads, I think Kevin will agree) that threading the film in there is quite a perilous task. I don't even want to talk about removing the film in case of an interrupted projection. So, threading the Bealieu requires you to push down on the threading/loop button until there's enough leader to attach to the take-up spool.
