Its our annual new year time of servicing the projectors. This task usually takes me a good few days to complete the collection throughout the various film gauges but has saved many a scratched film or in show projector failure I am guessing.

My beloved first GS1200 has given tremendous service and has been loved so enjoyed a pretty trouble free life except one new gear and belt in its time. Although a pricey machine new I've had value for money from this one also fitted with a 2 blade shutter for a bit more on screen illumination.

Film guides are removed and wiped with Silicone annually, that seems to work out well. I also use it on the plated guides in my 9.5 and 16mm machines.

Happy servicing boys and girls.

Hi, Lee
The silicone treatment seems a good idea. Can you illustrate for us what exactly you use.
Liquid or cream?

Hello Maurice.

I use the 3in1 Aerosol Silicone usually about £6. Spray it onto a lint free cloth then rub on for a smooth coat. Its best to remove guides where possible so as not to get any on capstans on sound machines. In difficult to reach spots use it on a cotton bud.
Leave to dry for 24 hours but it does actually dry quickly although I'm always cautious. Do all of my machines as I say once a year without a problem thus far.
Best wishes

Thanx for this tip Lee! Never thought to silicone spray the guides once a year. Great tip that I will now include in the maintenance program of my machines!

Good tip. I've used silicone lubricant on my cars but never thought of using some on projectors. I bought a 400ml can of the 3-In-One stuff at Halfords for £5.99 today. I have Eumig and Sankyo projectors. Is it OK to use it throughout the film path, including the gate, on silent models, please?

Don't get it on the lens. You will never get it off!

Paul makes a good point. I accidentally sprayed some silicone lubricant on part of my car's back window once. It was still there when I sold the car years later. It's probably best to remove the lens to a safe position before you start and only replace it when you've finished.
