Re: Eclair ACL New kid on the block ...

Phil --- check out the step-by-step directions for the conversion at:
and make sure that you feel comfortable doing it yourself. While the
directions are fairly detailed, they were written assuming that an
experienced ACL Tech would be interpretting them.
If you are new to working on the ACL, I would suggest that you forego the
mirror re-centering for the time-being. Although re-centering the mirror
would technically put the camera at 100% Super-16 specs, practical experience
suggests that it is not vital for the ACL (though the timing of
mirror/shutter/claw will have no margin for error.) The other parts are
simple enough to replace --- but when re-assembling the camera you will need
1) make certain that the shutter isn't scraping --- some gentle bending will
probably be required, and a great deal of patience;
2) Reset the timing of mirror/shutter/claw; (as the claw is just about to
advance the film, the shutter must be just closed, and the mirror just about
to cross the aperture opening; needs a jewels screwdriver. Tests must be
shot, or timing checked with a strobe light.)
3) The Ground Glass will need to be re-aligned anf focused; (needs a jewelers
screwdriver, a small piece of ground glass, a magnifying lens, and a ton of
4) The Flange will need to be shimmed and collomated; (needs a depth gauge in
mm and small piece of metal to place inside the aperture plate)
5) may need to add a shim under the cam/counter-0cam assembly (requires
calipers in mm);
6) Have a range of stainless steel washers on hand from .85mm to 1.15mm to
reset the tension on the mirror; you may need to have these machined ---
finding the exact thickness is critical. (I've also been sucessful shimming
with a piece of aluminum foil. but technically I recommend maching a washer
of exact thickness).
I plan to put instructions for ground glass realignment and focus on my site.
Perhaps if people are going to try the conversion themselves, I should add
"resetting the timing" as well.
PS - The ACL packs a lot in a tiny space with no breathing room. It is very
easy to turn a near-silent camera into a "machine-gun". Quieting an ACL is an
art unto itself!
