matt c Posted June 29, 2016 Share Posted June 29, 2016 I'd hazard a guess that you need graphite powder for irises and shutters. High temperature, won't dry out, and readily available. Stick graphite powder in a search engine of your choice. Link to comment Share on other sites More sharing options...
the kid Posted June 30, 2016 Share Posted June 30, 2016 I have used graphites before, worked well for an iris. A little TOO well. Shutters were fine with them. Link to comment Share on other sites More sharing options...
Jivemaster Posted June 30, 2016 Share Posted June 30, 2016 Graphite powder (again) it can sometimes be found in small dispenser bottles at locksmiths. Link to comment Share on other sites More sharing options...

Tomo Posted July 1, 2016 Share Posted July 1, 2016 Caution - Some shutters and irises have special coatings that mean they are lubricated-for-life and adding anything at all will basically destroy them. Check with the manufacturer first. Link to comment Share on other sites More sharing options...
mikelx Posted July 1, 2016 Author Share Posted July 1, 2016 The maintenance is on some old Strand lanterns pre Source4,so I don't think they did special coatings some 30 years agoThanks for the reminder though, I know ETC lenses are specially coated Link to comment Share on other sites More sharing options...
Tomo Posted July 4, 2016 Share Posted July 4, 2016 Yes, more than 25 year-old fixtures won't have any coatings on the shutter blades, so graphite will be perfect! Do check the irises though, they're probably not original. I rather doubt any irises are likely to survive 30 years of use... Link to comment Share on other sites More sharing options...
alistermorton Posted July 4, 2016 Share Posted July 4, 2016 Interesting point, Tomo - I wonder how old our Patt 23 irises are. Link to comment Share on other sites More sharing options...
Salazar Posted July 10, 2016 Share Posted July 10, 2016 Our Patt 23N irises are at least 40 years old now and no problems. Link to comment Share on other sites More sharing options...
