Graphite powder, though it is an fantastic dry lubricator, has been shown to be corrosive to aluminium when there is possibility of moisture being present. Consequently, the USAF banned the utilization of Graphite lubricants on any USAF aircraft, several years gone. While graphite was the standard when the Velocity Graphics were now, there is at present a much better alternative : Molybdenum disulfide powder ( Chemical symbol=MoS2 ).
A Graflex pamphlet on their roll film backs ( with the film flattening pin rollers ) advises the correct way to lubricate them, with Z Molykote powder ( Dow Corning trade name for MoS2 powder ) melted in alcohol and applied in small quantities to the ends of the pin rollers, letting the mixture penetrate. The alcohol evaporates, and after wiping off the surplus, you have the MoS2 powder left at the back in the rollers.
Graflex even sold this powder under their part number. It's a dark, nearly black powder, like graphite in appearance. Sloppy if you spill it. Used just like graphite powder. You can "burnish" it on metal parts by rubbing it in with a fabric or stiff bristle brush. Some target shooters burnish MoS2 powder on their bullets--better accuracy, less bore fouling with lead. Ought to work extremely good on shutter leafs ( carefully! ) Some bike chain lubes have MoS2 powder in a carrier liquid to penetrate the chain links and then vaporize, leaving the powder behind. Ought to work in screens too .
MoS2 can be acquired from at least two sources : local distributors ( bearing supply homes, as an example ) typically have the DJX Corning Molykote Z powder in ten oz bottles for just about fifty bucks. Or online at : Rose Mills Company, LLC. Click on Bemol Lubricants and scroll down to the three grades of powder they sell online . I love the superfine grade, with particle sizes avg. 1.5 nanometers. It actually gets into small spaces. ( .001 inch of clearance equals twenty-five microns--I expect some camera shutter clearances are even less this ) Sold in one pound tubs ( one or two lifetimes supply ) for just about 30 greenbacks plus shipping. ( a bargain ) Get a tub and sell low amounts on Ebay for mucho bucks each!! Spray the powder in your door locks. Masses of other potential uses, it won't go to waste. Use your imagination.
The Z Molykote powder averages four to 10 microns particle size, and would also work if you'd like to buy locally and use precisely what Graflex mentioned, but it is expensive. Read about it at : Dow Corning Click "Products / info sheets" and follow the rabbit trail to get a PDF file you can download. ( product information sheet touches on use on camera screens ) The site will also give you a catalogue of local distributors in your area.
