SINAR: mounting Copal shutter to lens?

Hi folks,

In my quest to better understand my newly acquired P2, i decided to dis and re-mantle it!

One thing so far which has me stumped:

Please take a look at the picture below. Am i right in thinking that nipple (sorry if that's the wrong word! ) A should go inside hole B?

If so, what is the trick to achieve that as they seem very difficult to align?

Thanks in advance!

Hoping someone can advise on this!

Additionally, could anyone tell me the purpose of the two accessories shown in the images below?

The plastic piece with lens front on it is used to make an extra bellows into a lens shade. The octagonal holes it onto an octagonal rod. The other end of the rod fits into a similar hole on the front standard. The extra bellows clips into the piece.

The cable is part of the flash system for the Sinar shutter.

I've never tried to fit the pin on the shutter into the hole. I just attach the lens board in the proper orientation and it works for me.

The red spots are your clue. Rotate the lens board so that they line up and all should work. Don't force anything.

@juan, thanks for the info!

About the lens aperture / shutter connection: so you're saying that the "nipple" should actually just push on the aperture lever at the point marked in yellow in the pic below?

If so, it's kinda strange, why is the lever (green outlined) shaped like it is and why is there a hole it it?

It happy to believe you, but the design of the lever makes me wonder.

The point being, if the nipple goes in the hole, that gives a slightly different aperture from if it pushes on the lever!

As Fred Picker would say, "Try it."

I tried it, it works!

My doubt is that, if the nipple is supposed to go into the hole, you'll get a different aperture compared to it pushing on the side of the lever.

The design of the lever suggests that either it's supposed to go in the hole, or otherwise has some other functionality. That's my doubt / question.
