Author Topic: Knocking Sound Robert E. Allen Phenomenal Film Handler Posts: 1078 From: Checotah, Oklahoma Registered: Jul 2002 posted 01-11-2014 02:21 PM                     One of my Simplex 35s has developed a sound that, if it were in my car's engine, I could only describe as a knock. The machine seems to have plenty of oil as it splashes on the glass. Do I need to worry?

That makes it possible for the affected shaft to wobble around inside the hole, instead of rotating smoothly. This was a cause of knocking for some of my first machines.  |  IP: Logged Frank Bolkovac Film Handler Posts: 27 From: Monroeville, Pa.

Seriously... You are having so many problems lately I'm thinking digital is a better alternative for you. Knocking can also be caused by a vertical shaft that has come loose at the bottom bearing retainer. The possibilities here are almost endless... Getting back to should you worry or not... What's your conversion to digital time frame? If that's happening soon then don't worry. If that's not any time soon then start worrying in a week or two or if the knock gets louder.

I can hold it with my hand and there's no knock. As for digital it may take me to the end of the year. I'm already feeling the lack of film prints problem.  |  IP: Logged Peter Howard Film Handler Posts: 44 From: Forster, NSW, Australia Registered: Dec 2005 posted 03-19-2014 09:19 AM                        Slightly OT, but can you still get 35mm trailers on all titles, Robert?  |  IP: Logged
