Polaroid 195 shutter lubrication and missing spring

[rbultman]

Two issues here.

I have a Polaroid 195 with the 114mm Tominon lens that had a slow shutter release. I disassembled the shutter and cleaned the surfaces of the speed setting ring, cover plate, and cocking ring. The shutter now operates fine although I have not tested the speeds. A manual I found on line for Seiko shutters states that these surfaces should be lubricated. Can someone suggest a lubricant? The first picture has the speed ring and cover circled in black. The cocking lever is at the bottom of the shutter in the picture.

Now the second issue...

While re-assembling the shutter into the front standard, I had difficulty getting the retaining ring started on the shutter thread. The aperture and speed rings were slightly in the way. I came up with the (not so) brilliant idea of removing the rings so that I could get the retaining ring started. There are 3 balls that engage detents (1 for the speed ring, 2 for the aperture) and associate springs. Long story short, I lost one of the springs. I'd like to find a replacement for the spring. Anyone know where I can get one? The spring measures approximately 0.055" OD X 0.100" long. The spring in question is shown in the following picture circled in orange. The aperture ring is shown with one ball and spring installed an another below it.

Any help would be greatly appreciated.

Regards,
Rob

oh yeah that black hole eats everything. sweep your floor n work surface, then run a magnet through the dirt pile.

those tiny springs can be found in glasses hinges. if you have an old pair laying around?

that ring in the photo with the ramps... you can use lithium or moly or silicon grease but only a very very light smear on the ramps the pins ride on.

when putting that ring back, make sure the pins are in their slots, if trapped below, that retaining ring will be very hard to get on n will also squash n bend the pins. as you put the ring on, rotate it a bit as the pins find their place.

Is the automotive lithium spray lubricant ok? I was thinking of spraying it on and the wiping most of it off, or spraying it onto a cloth or paper towel and then wiping the surfaces with it. Do you have a recommended method?

just apply a very tiny amount on the ramps only, not the entire plate. the pins ride the insides of those slots. put the ring back on and see what i mean?

by very tiny amount... i mean a smear that is a molecule thin. wipe it on by finger.

spray the stuff onto a piece of paper n just wet a finger. the insides of the slots are where you want it.

find a replacement for the spring

Donor camera for parts.

Unfortunately that camera is "collectible", aka expensive. Finding a donor might not be easy.

Thanks to John's kindness in supplying some replacement spring material, I was able to reassemble the shutter assembly and aperture and speed rings. I just have one more small mechanical issue to fix and a couple if cosmetic issues and it will be ready for a film pack.
