Hi All, You may have seen in other threads that I have a Sinar electronic behind the lens shutter that is intermitent.

Sometimes it works fine at all speeds without any problems, it manually opens and closes using the slide switch to focus etc. The iris control also works fine.

Occasionally a blade (two rotary type) will stick and if it jams it will blow the 1.25A slow blow fuse in the battery box ..I've blown about 20

The more I play with the shutter the more convinced I am that a little lubrication on the circumference of the blades will cure the problem...Here comes the question.......What type of grease/graphite/other should be applied and is it easily available?

Any offers of help appreciated....Cheers Dave

ps If I get it working reliably I promise to shut up about this shutter:rolleyes:
