Hi Les --- Do you have any of the ACL II Rosettes for sale yet? Thanks.

Ray,
It's very plausible to do your own Nikon conversion on the CA, I've done
many the way you cite. The only difficulty you will have will be making
the
pin and release mechanism.
I order Nikon mounts for the F301 camera as these fit perfectly inside the
CA convertor. Whichever Nikon mount you are using you're going to have to
get a precision engineer to lathe the excess off the CA mount until it's
close to a thousandth of an inch (No problem as most machine shops can
handle this precision.) They shouldn't charge you any more than about $30
or so to do it. Ask them to tap screw holes for the Nikon mount to be
fitted down. Once they have machined the CA down and the Nikon ring is
screwed into place you will have to measure the entire depth of your mount
and ensure it's exact to approx + or - 5 microns. They're unlikely to have
a depth gauge such as most technicians have, but I'm sure they have precise
enough tools to measure this depth. Remember that the final length of the
CA convertor with the Nikon mount on top will be the Nikon depth
subtracting
the C mount depth of the Eclair ACL. Otherwise you'll have to check the
entire Nikon depth with the mount on the camera right up to the gate to
ensure your engineer has lathed the exact amount off.
Ask the engineer to cut a rectangular channel into the mount beneath the
locking pin hole on the Nikon mount. This will allow clearance for the
release catch to be fitted and pushed up and down when a lens is mounted.
You will have to drill a small hole into the CA mount for the bottom of the
locking pin to slip into when the release catch is pushed down (you can do
this at home with a small drill).
To make the pin and release just find an offcut steel pin that fits snugly
into the pin hole inside the Nikon mount. The release can be made out of a
piece of thin steel, and bent in such a way that it is self sprung.
Unfortunately it's a bit complex so I tend to drop a tiny spring down the
clearance hole to push the release catch back up. I'd have to send you a
diagram of how to make it, but it can be done at home for next to nothing
with a drill and a file.
You can go ahead and make the mount meanwhile without the locking pin, it's
just important to get the right depth.
Auction it on Ebay and you'll get a lot more for it than a simple CA.
Regards
Robert
Hi all,
Has anyone attempted the conversion of their original CA-1 mount to a
Nikon mount? I was looking at my increasingly obsolete CA-1 mount
wondering what to do with it (besides selling it cheap on ebay) and it
occurred to me, given the CA-1 has a flange focal depth of 48mm and
Nikon is 46.5mm the conversion might be fairly simple. The internal
brass sleeve can be removed by undoing 3 retaining screws. The brass
sleeve is approximately 2mm thick so removing that leaves us at 46mm.
Add the depth of the Nikon bayonet ring (the one I have is appoximately
1mm thick) and you are pretty close. Some precision shaving of the mount
might have to be done (1/2 a mm or so) to get us back to 46.5, but any
good machine shop should be able to do it. The trickiest part looks to
be the adding a locking pin for the Nikon mount and getting the Nikon
ring dead center on the original ACL mount. Surprisingly the Nikon mount
is approximately the same diameter as the ACL mount.
I purchased a Nikon-ACL mount about a year ago and upon studying it, it
looks as if it once enjoyed life as a CA-1 mount and was converted at
some point (albeit it is obviously a professional conversion).
Whadda ya guys think?
-Ray
