M3

[stephen_w.]

When wound and cocked the film advance lever, under stress, moves w/o moving the film. with my m2/4/6 the lever stays firm. why is that?

 

<p>

 

is it the clutch?

 

<p>

 

is it normal?

 

<p>

 

will i damage the mechanism if i slip it too much?

 

<p>

 

what is the purpose of the slipping, i prefer solid.

Steve:

Is your M3 a single or double stroke 3? Both of my M3's slipped

after cocking, but after they were changed to single stroke it is

just like my M6. This is normal on a double stroke. I did not

intentionally make mine slip and I did not have a problem. The

double stroke takes getting used to, but after 30 years it is second

nature (stroke).

[stephen_w.]

it is a double stroke. the previous questions remain.

[john_collier2]

Yes.

 

<p>

 

No.

It is not going to get better as the damage is done.

 

<p>

 

It is not supposed to slip, it should be solid.

Time to get it fixed. There are no spare parts for the DS

mechanism so you will have to a SS mech installed.

The slippage happens with a lot of cameras, and I think it is to

prevent you from ripping the film sprockets. The whole Leica double-

stroke concept was to prevent film stress (I am grateful that they

dropped that "feature"). I haven't tried it on my SS M3, but I would

be loath to try to induce slippage. In the worst case, you could

conceivably polish the clutch surfaces and make them slip all the

time.

[stephen_w.]

john, it was cla'd by dag late last year.

i had another ds m3 15 yrs ago, and it did the same thing, wasn't

broken.
