I hope you guys don't mind I started another topic, but here are some photos of my manual thread conversion of an Elmo ST-180.
I cut off the upper section that connects to the loop former and added a new roller to prevent too much contact when exiting the sprocket.
And here I cut away access to the lower sprocket for easier threading and unthreading. Finally, I permanently moved the lower loop guide into its recessed position and use the loop restorer to help form the lower loop when threading.
On this unit I also did a two blade shutter conversion and added a mounting bracket for a Film-O-Clean. Recently I have been using a small barrel Bell and Howell 2 inch lens for a smaller picture at a longer throw to match the size from my 16mm machines at the same distance. Overall this projector has been quite fun to get to this point and shows a very nice bright image. Now I feel it will be very safe for my precious films as well!
Looks good, does the extra roller "diameter wise" is it large enough to keep the film from wearing in that "green" guide?, if so thats a good fix. I notice you have also removed the green feed guide thats right at the front. That was another area that would scratch film once worn. The Elmo ST-180 is a nice projector, what you have done, plus fitting a two bladed shutter makes it even better...well done.

Graham, I would like to find a roller(or make one)just a little bigger but for now it appears to relieve pressure against the sprocket guide, so I think it will inhibit wear.
Eventually I will do something about the tension thingy after the pinch roller too, as I know that can also wear and scratch.
