Yeah, in a fit of Shelter-In-Place induced madness, I decided to disassemble a
Supermatic (X) Shutter with a bum 1/10 speed. Surprisingly, I got it back
together and now all the speeds work, though most of them are a hair fast.
When I’m working on something like this, I typically work over a small cookie
sheet; not only does it keep small parts from going astray, but anything that
falls off unexpectedly make a distinct ’tink’ when it hits the pan. I do like
the idea of working in a bag for anything involving springs, I had never
thought of that. For parts storage I usually use poly inventory bags from
Office Depot. The 1” x 2” size works well for this application. I’ve been
meaning to get some Deoxit for my motorcycle projects (Lucas connectors,
anyone?), but I’d never thought of using as a lubricant. The biggest problem I
had was the about half my tweezers had some residual magnetism, which makes
working with small parts irritating as all get out. Another thing that is
useful is a set of dental picks: These can be used to unhook/hook springs or
nudge parts into place.

Its helpful to have a couple of DuMont style non-magnetic tweezers but even
regular make up tweezers will do.
I have recently been using Caig Labs Deoxit 5, an electronic contact
cleaner as a lubricant. Seems to work. I apply it with a small artist's brush.
A magnifying glass, a jeweler's loup is good. You can get reading glasses
at the 99c store for 99c. These are often very expensive ones marked down.
It helps to have some specialized tools but I am not sure which ones, if
any, you need. If a lever has been pushed out of place you will see it pretty
quickly. Work in a shallow box and make sure the corners and edges don't have
holes. This will prevent losing screws and small parts. I use old medicine
bottles for parts, also small freezer bags work well. A close visual
inspection will probably find the trouble. Most shutters are not very
complex. Don't get fatigued and have a good strong light to work with.
Good luck and report what you find. Since its broken you really can't break
it further. Have a shot at it.
