  • Elmo ST 1200 HD issues

    Picked up old st1200HD . It turns on, something spins inside, but it doesn’t seem to spin the threading mechanism - see the video.

    Does it need cleaning up and lubing or a motor needs replacement?

    Ooops, looks like I need new belts.

    It’s a big mess

    a bit confused here - on eBay there are 2,4,5 sets of belts?

    what is the best place to buy - in North America?

      Hi Martin,

      The Ebay seller isellprojectorbelts has always done well by me. I've probably bought something like 10 sets of belts over the years.

      On ST-1200HD there are these belts and "belts"

      1) Motor belt
      2) Rocker assembly belt
      3) Belt to the rear spindle
      4) Footage counter belt
      5) Shutter wheel surface replacement band

      You can probably get it to run by replacing 1,2 and 3. You may need to remove the decomposed remains of 5, and you can replace it if you want (I did).

        Thanks, how do I remove this wheel - it gets stuck to the frame that holds the fuse. I want to clean the mess behind.

          I don’t remember having that problem, then again it‘s been 8 years since I did that particular surgery.

          Can you pull the shaft out from the other end (the roller), to make clearance?

            Weird, I looked at this video, and it appears the one on video has 3 holes, mine has 4? Around 9:30mins in the video

              Managed to force it out. I tried cleaning as much I could, but there is a spring at the back Click image for larger version

ID:	78892 that I can’t clean due to the limited clearance - I hope it won’t affect operations?

                The holes are there to create the final balance of the flywheel. They may vary in number.

                  Looking at your last picture Martin it looks like the drive pulley on the motor might be starting to crack. I would keep an eye on that if I were you. Van Eck can supply replacements if needed.

                    I bought square belts frpm The Real Image for my ST1200.
                    Never knew I could glue those myself.
                    Probably not cleaned good enough, cause the takeup reel cannot take the full 360 meter reel and stops turning when it gets more heavy
                    This have always been the case, but in the past 240 was the max we used anyway.

                      I managed to install the shutter wheel belt using your tie wraps method. Didn’t remove anything.30 mins job now that I know how to do it.

                      the problem is I didn’t have the glue, so I was hoping it would stay on without it as the eBay guy advised you. NOPE! It fell off almost immediately.

                      which glue widely available in North America I should use?

                      and how many glue points should I have?

                      thanks Click image for larger version

                        Hi Martin,

                        I used Eclectic Products E-6000 adhesive:

                        http://eclecticproducts.com/product/...-tip-adhesive/

                        This is a slow drying, pretty tough, temperature resistant adhesive, and works nicely for this. It's nice to have for other purposes too.

                        It's very commonly used by people that make jewelry, so in addition to Amazon (etc.), you should be able to find it in places like Michaels, maybe hardware stores. I think I bought it at Home Depot once too.

                        I put the tyraps on about every two inches, and applied the cement in between. When it was cured, I cut the tyraps off. This worked out to about 8 bonds around the circumference.

                        Every so often I go back in and check the bonds and redo any that have loosened. Most times they are all OK.

                        (I can't imagine this working without the glue!)

                          Just curious--has anyone found a solution for the anemic capability for larger reels on the ST1200HD? The rewind is truly pathetic and slows to a crawl before stopping on larger reels. On top of that, it spools the film so loosely that it makes more sense to use mounted rewinds than to use the projector's function. I've owned several projectors over the years--Eumig, Chinon, and Elmo--and none had a rewind as marginal as the ST1200. It's like the Elmo engineers set the bar low and barely hit the mark on that count.

                            Done, but the 2 rubber wheels (both 18 and 24) are still not touching the shutter wheel…

                            How do I go to close the gap and adjust the « pressure »?

                            thanks

                              Ethan, I take it you are pushing the Yellow rewind lever down when selecting reverse to rewind the film. I have never really seen an issue with rewinding on the ST1200 range of machines.
